Empty function removed since ´public bool addSchemeLimb()´ makes sure the function never gets called.

Global dimension functions removed and replaced with methods in XpShape.

To prepare for a full implementation of AutoElevations in 16.5 Minor, interface changes around AutoMeasure has been done.

Parents clientbound changes are no longer passed to parentClientBoundChanged method.

articleView.cm

The behaviour of the additional adjustments have been changed to allow for standardization of the main article view. New interfaces have been added and others modified to manipulate adjustments instead.

The overall stability and performance of CollabPro has been improved:

• A facelift to simplify user experience
• Cleanup and simplification of window resizing logic
• Improvements to logging and error handling
• CollabPro now attempts to synchronize realtime project data with server on load, before applying appropriate load world or space hooks, to ensure data consistency.
• RTInvalidate calls that were invoked before the RT runtime is initialized are now deferred and will be invoked when the runtime is ready.

See also related changes in cm.network.cbb.

For a developer's introduction to supporting CollabPro (G3), refer to this document.

The DWG dialog (commonly known as "CAD Settings") have received a large update to allow selecting and editing multiple DWGs at the same time. As a result, many interfaces have been updated to accommodate the new functionality.

Apath2D would sometimes return incorrect or inconsistent results when asking whether it contains a point or not.

It has been updated to have fewer errors and more consistent behavior when the point lies on the edge of it. This may in rare cases cause issues in code that relied on the incorrect behavior. Fixing these issues should lead to CET having fewer unexpected issues overall.

Cleanup of Dwg entity classes, removing redundant constructors. In preparation for upcomming improved DWG export.

CBBClient is the networking client used by CollabPro to exchange data with the cloud. We have improved the connection stability and reliability through better error handling and clearer status information.

DIB Images

The handling of DIB (Device Independent Bitmap) images by CET Core has been improved, and it can now draw DibImage that have transparency.

As DIB images are regular memory allocated objects, it does not consume Windows GDI handles, resulting in reduced system resource usage, improving performance and stability.

MessageWindow

MessageWindow was originally made only to show in toolbox libraries. But now that there are more cases of it being used generally for UI, changes are made to easily use and size this outside of toolbox libraries. It sizes itself according to the text along with 3 sizing modes:

• No width is provided : Size itself without text wrapping. (Use setWidth passing a 0 value)
• Width is provided : Attempts to wrap the text if it crosses the width provided. (Use setWidth)
• Calling extendRight : Attempts to wrap text according to how far it can extend right. (Use extendRight)

As CET manufacturers grow in scale regarding products, we also need to keep that in mind of GDI Ojects from Windows having a limited amount for use in showing each image. While using any ExploreDialog in CET, the amount of GDI Objects use can soar if the folder being navigated is full of products being shown. Hence changes are made to use DibImage instead of MemoryImage for that very purpose. It is strongly recommended to look through your code base and determine whether to migrate into using DibImage wherever large amounts of images are being shown. Here are some suggestions on how to migrate.

Read as DibImage from a source.

If the image is loaded from a source, it is best to save the image as a DibImage from the start. Utilizing the functions inside cm/win/DibImage.cm, which takes in either Url, RawImageData, MagickWand, Stream.

MemoryImage as a transient.

If beginning with from DibImage is too difficult, you can instead opt to convert MemoryImage to DibImage, then destroy it, else it depends on the garbage collector to clean up the GDI Object. You can utilize memToDibImg(MemoryImage) in cm/win/DibImage.cm

Props argument compiler warning

A warning has been added when passing a str->Object with the same name as the props argument name. This to make the developer aware that this will NOT pass your value as argument. Keyword and value will be added to props.

public class MyClass {
    public constructor() { }

    extend public void put(str key, props: args) {
      	pln(#args);
    }
}

{
    str->Object args = {str->Object: "a"->1};

    MyClass myclass();
    myclass.put("key", args=args);// props argument value has the same name as the props argument name
}

args={"args"->{"a"->1}}

class AbsItemTagInfo

Two new constructors have been added to the AbsItemTagInfo class.

• str articleCode parameter has been added
• Allows for setting the new str articleCode field on construction

New: public constructor(str text, str k, AbsDwgLayerInfo info, str articleCode, double textHeight=4inch) {}
New: public constructor(str text, str k, AbsDwgLayerInfo info, str textType, str articleCode) {}

Dib image resizing functions

The following resizing interfaces have been replaced:

Old: public DibImage dsDibResize3(DibImage im, sizeI newSize, str filter=null) : deprecated {
New: public void dibResize(DibImage im, sizeI newSize, str filter=null) {

class DsiPData

Changed: public double basePrice()

The basePrice method was refactored to remove the final and inline modifiers and is now declared as an extend public method.

Old → New behavior

Old:

• Declared as final → could not be overridden by subclasses.
• Marked inline → compiler inlined the method for performance optimization.

New:

• Declared as extend public → method can now be extended/overridden.
• inline removed → no longer enforced as an inline method.
• Core logic remains unchanged:
  • Returns the styleProduct price if present.
  • Returns -0.01 otherwise.

class DsPart

Constructor Migration: List Price → Base Price + Option Price Sum

The DsPart class constructors have been expanded and split to support the new part pricing system (introduced in 16.5). New constructors now accept basePrice and optionPriceSum separately.

Old constructors that use list price remain available but are marked for future deprecation.

Old Constructors

• constructor(Snapper, DsPData, double listPrice, …)
• constructor(Snapper, DsPData, str articleCode, str description, double listPrice, …)
• These constructors use list price (a single cached price) instead of separating base + options.
• Still supported in 16.5 for compatibility.

New Constructors (preferred, introduced in 16.5)

• constructor(Snapper, DsPData, double basePrice, Double optionPriceSum, …)
• constructor(Snapper, DsPData, str articleCode, str description, double basePrice, Double optionPriceSum, …)
• These constructors use separate base price and option prices instead of utilizing a single cached list price
• Preferred in v16.5+

Impact

• If you use list price constructors today → update to the new basePrice + optionPriceSum pattern
• See new pricing API documentation in cm.core.part.Part compile-time section for more migration tips

New Pricing API

The following functions were introduced or modified to support the transition to the new part pricing system. Find more documentation on the new pricing system in the compile-time section for cm.core.part.Part.

Added: public Double generateOptionPriceSum() {}
Removed: public double basePrice() {}
Removed: public void performPriceConversions(ProjectInformation projectInfo) {}

Added: extend public Double generateOptionPriceSum()

Old → New behavior

Old:

• Not applicable.

New:

• If the Part has an associated pData (DsPData):
  • Delegates to pData.optionPriceSum(specOptions, this)
• Otherwise:
  • Falls back to superclass implementation (super()).

Impact

• If you have custom option price logic, override generateOptionPriceSum() in your extended Part class.
• Invalidate the cache (invalidateOptionPriceSum()) when option state changes to trigger regeneration.

Removed: public double basePrice() {}

The basePrice method was expanded to support the new pricing framework by adding parameters and delegating to the superclass when new pricing is enabled.

Old: public double basePrice() {}
New: public double basePrice(bool includeChildren=false, Space space=null, bool translatePrice=true)

Old → New behavior

Old:

• Simple signature:
  • public double basePrice()
• Always derived base price from:
  • Adjustments via PartSpecial (replace or append)
  • _data.basePrice

New:

• New signature with optional parameters:
  • public double basePrice(bool includeChildren=false, Space space=null, bool translatePrice=true)
• Behavior changes:
  • If useNewPricing is enabled → delegates directly to super()
  • Otherwise → falls back to legacy logic (_data.basePrice with PartSpecial adjustments)

Impact

• Functional expansion: method now supports contextual pricing (child parts, space, translation)
• Under the new pricing system, logic comes from the superclass, not local overrides
• Legacy behavior retained for backwards compatibility

Removed: public void performPriceConversions(ProjectInformation projectInfo) {}

• This overidden method was removed as it is a complete duplicate of the super class version (in ProdPart).

New Lead Time Interface

As of 16.5, a new interface for lead time has been added to core Part and overridden in DsPart. It's value is displayed in the new LeadTimeColumn implemented in cm/core/init/leadTimeColumn.cm.

In cm/abstract/dataSymbol/parts.cm

/**
 * Get lead time string.
 * Ex. 20 days, 3 weeks, etc.
 */
public str leadTime() {
	DsProductType product = pData.product();
	if (!product) return super();

	int days;
	for (ref in product.leadTimeProgramRefs()) {
		DsLeadTimeProgramType ltp = pData.leadTimeProgram(ref);
		if (!ltp) continue;
		days = max(days, ltp.days);
	}

	return days > 0 ? spnn(days, ' ', days == 1 ? $day : $days) : "";
}

Other DsPart changes

Removed: public void generateOptAdjustmentSifRows(SpecOption opt, str[] lines) {}

The abstract ProdPart interface for generateOptAdjustmentSifRows has been changed to accept PartOptionItems instead of SpecOptions. As a result, the empty override of this function in DsPart has been removed entirely.

Old: public void generateOptAdjustmentSifRows(SpecOption opt, str[] lines) {}

Changed: public str optSpecialKey(SpecOption opt) {}

The abstract ProdPart interface for optSpecialKey has been changed to accept PartOptionItems instead of SpecOptions.

Old: public str optSpecialKey(SpecOption opt) {}
New: public str optSpecialKey(PartOptionItem  opt) {}

Changed: public PartInfoTree[] infoTrees() {}

When collecting PartInfoTrees on DsParts, the specOptions sequence is no longer filtered by DsSpecOptions. All options within the specOptions sequence will have a tree constructed.

public PartInfoTree[] infoTrees() {
	PartInfoTree[] items();
	PartInfoTree[] parents();
	
Old:	for (DsSpecOption tp in specOptions, index=i) {
New:	for (tp in specOptions, index=i) {
            ...
        }

	return items;
}

Changed: public str flattenableKey() {}

With the addition of the new part attribute description/notes system, DsParts now need to be differentiable/split by their attribute values.

The following change has been made in flattenableKey to account for this:

public str flattenableKey() {
	StrBuf buf(uniqueKey());
	
	...
	
New:	buf << annotationFlattenableKey();

	return buf.retireToS();
}

class DsFreeformPicklistPart

Removed: public double basePrice() {}

The basePrice method was expanded to support the new pricing framework by adding parameters and delegating to the superclass when new pricing is enabled.

Old: public double basePrice() {}
New: public double basePrice(bool includeChildren=false, Space space=null, bool translatePrice=true) {}

Old → New behavior

Old:

• Simple signature:
  • public double basePrice()
• Always derived base price from:
  • item.price()
  • Adjustments via PartSpecial (replace or append)

New:

• New signature with optional parameters:
  • public double basePrice(bool includeChildren=false, Space space=null, bool translatePrice=true)
• Behavior changes:
  • If useNewPricing is enabled → delegates directly to super()
  • Otherwise → falls back to legacy logic (item.price() with PartSpecial adjustments)

class DsFreeformItem

The following functions were added to support base price for DsFreeformItems.

Added: extend public str currentCurrencyKey(str key) {}
Added: extend public double basePrice() {}
Added: extend public double basePrice=(double value) {}

Added: extend public str currentCurrencyKey(str key) {}

The handling of currency-based pricing was refactored to make currentCurrencyKey more flexible.

Old → New behavior

Old:

• currentCurrencyKey() directly constructed a key using cDsFPriceKey and the current currency symbol

New:

• currentCurrencyKey() now delegates to a new overload:
  • currentCurrencyKey(str key) → builds a unique freeform key from the given key and currency symbol.

Added: extend public double basePrice() {} and extend public double basePrice=(double value) {}

Explicit support for base price has been added to DsFreeformItem.

Old → New behavior

Old:

• Only list price (price) was supported via field data

New:

• Added explicit basePrice field accessors:
  • basePrice() → retrieves the base price using cDsFBasePriceKey
  • basePrice=(double value) → sets the base price.

CatalogTocLimbBuilder changes

We have removed the field info field from CatalogTocLimbBuilder. You can get relevant information from code and versionCode fields.

Old: private DsSqlImportActiveCatsInfo info : public readable;
New: private str code : public readable;
New: private str versionCode : public readable;

DataCatalog changes

The following methods with bool retDibImage=true have been removed. DibImage are now used by default for performance reasons.

Old: extend public Image getThumbImage(Url url, sizeI size=sizeI(),
                                       DsCommunicationCB callback=null,
                                       int priority=2, bool retDibImage=false) {
New: extend public Image getThumbImage(Url url, sizeI size=sizeI(),
                                       DsCommunicationCB callback=null,
                                       int priority=2) {

Old: extend public Image getThumbImage(DsiPData data, sizeI size=sizeI(),
                                       DsCommunicationCB callback=null,
                                       bool useCache=false, int priority=2, bool retDibImage=false) {
New: extend public Image getThumbImage(DsiPData data, sizeI size=sizeI(),
                                       DsCommunicationCB callback=null,
                                       bool useCache=false, int priority=2) {

dsMemoryImageCache.cm

We have improved handling of DibImage by the system. It can now draw DibImage that have transparency. This means we no longer need convert a DibImage into a MemoryImage and cache it. The following interfaces have been removed:

Removed: public MemoryImage dsThumbnailMemImageCache(DibImage dib) {
Removed: public void startDsMemImageCacheIdle() {
Removed: public int dsMemoryImageCount() {

class MirrorSelectionAnimation

Old: extend public View currentView() {
New: public WindowView currentView() {

The visibility of many interfaces across the whole abstract have been changed from public to package or private, as they were not intended to be used elsewhere. If you require any of the changed interfaces, consider making a local copy of it or contact developer support.

The following function has been removed from K2ApplianceLibrary:

Removed: public void addSchemeLimb(LibraryLimb parent)

The following function has been removed from K2SinkLibrary:

Removed: public void addSchemeLimb(LibraryLimb parent)

Global dimension functions removed:

Removed: public double getCabinetWidth(XpShape shape)
Removed: public double getCabinetDepth(XpShape shape)
Removed: public double getMeasureWidth(XpShape shape)
Removed: public double getMeasureDepth(XpShape shape)
Removed: public double getMeasureHeight(XpShape shape)

Use these methods instead:

public double nominalHeight()
public double nominalWidth()
public double nominalHeight()

Dib image for whitegoods appliances

The WgApplianceEnvSnapperDibButton class has been removed as LazySnapper3DMemoryButton has been updated to use DibImage.

Old: public class WgApplianceEnvSnapperDibButton extends SnapperImageButton {
New: public class WgApplianceEnvSnapperButton extends LazySnapper3DMemoryButton {

KitchenAutoMeasureGroup

When adding a measure to the group, the snapper which the measure belongs to needs to be passed along with it.

Old: final public void add(KitchenAutoMeasure measure) {
New: final public void add(Snapper snapper, KitchenAutoMeasure measure) {

createAutoMeasures now returns which snapper that are mapped to which AutoMeasures.

Old: public KitchenAutoMeasure{} createAutoMeasures(Snapper{} snappers) {
New: public Snapper->KitchenAutoMeasure{} createAutoMeasures(Snapper{} snappers) {

accept now requires the AutoMeasure which belongs to the snapper.

Old: final public bool accept(Snapper z) {
New: final public bool accept(Snapper z, KitchenAutoMeasure measure) {

autoMeasureToGroups now requires the AutoMeasures to be mapped from their Snapper.

Old: public KitchenAutoMeasureGroup[] autoMeasuresToGroups(KitchenAutoMeasure{} measures, symbol category=null) {
New: public KitchenAutoMeasureGroup[] autoMeasuresToGroups(Snapper->KitchenAutoMeasure{} measures, symbol category=null) {

KitchenAutoMeasures

The global public function updateAutoMeasures now have closeElevationDialog=false as a default argument.

Old: public void updateAutoMeasures(Space space) {
New: public void updateAutoMeasures(Space space, bool closeElevationDialog=false) 

The following function has been removed from DesignDialog:

Removed: public void parentClientBoundChanged()

class COMPart

Removed: public double customListPrice(bool includeChildren=false, str currency=null, Space space=null) {}

The pricing override in COMPart shifted from a custom list price implementation to a standardized basePrice override.

Old: public double customListPrice(bool includeChildren=false, str currency=null, Space space=null) {}
New: public double basePrice(bool includeChildren=false, Space space=null, bool translatePrice=true) {}

Old → New behavior

Old:

• Method: customListPrice(..)
• Returned pricePerUnit() as the list price unless includeChildren=true (in which case 0).
• Treated COM pricing as list-price–based.

New:

• Method: basePrice(..)
• Calls super(..) for base price, unless includeChildren=true (still returns 0).
• Pricing responsibility moved to align with base price in new model instead of custom list price.

Impact

• Aligns COMPart with the new part pricing API (basePrice + optionPriceSum).
• Removes dependency on customListPrice (legacy, tied to pre-16.5 system).

Engine entry changes

In class MhEngineEntryBase, removed argument MhEngine engine from method parent as it is no longer required (explained below).

public class MhEngineEntryBase {
    Old: extend public MhEngineEntry parent(MhEngine engine) { return null; }
    New: extend public MhEngineEntry parent() { return null; }
}

Moved a field MhEngineEntry parent from child class MhEngineConstructionEntry up to the parent class MhEngineSnapperEntry.

public class MhEngineSnapperEntry extends MhEngineBoxEntry {
    New: public MhEngineEntry parent : copy=reference;
}


public class MhEngineConstructionEntry extends MhEngineSnapperEntry {
    Removed: public MhEngineEntry parent : copy=reference;
}

With this, MhEngineSnapperEntry now has a direct reference to its parent entry. The parent() method (previously parent(MhEngine engine)) no longer needs to refer to its snapper's parent.

public class MhEngineSnapperEntry extends MhEngineBoxEntry {
Old:
    /**
     * Parent.
     */
    public MhEngineEntry parent(MhEngine engine) {
        ?MhSnapper parent = z.parent;
        return engine.?entry(parent);
    }


New:
    /**
     * Parent.
     */
    public MhEngineEntry parent() {
        return parent;
    }
}

For your info, there is now a proper interface to change the parent of an engine entry.

public class MhEngineEntryBase {
    New: extend public void changeParent(MhEngine engine, MhEngineEntry newParent) { }

In class MhEngineBoxEntry renamed methods box unmodifedBound() to box unmodifiedBound() and Transform unmodifedTransform() to Transform unmodifiedTransform().

public class MhEngineBoxEntry extends MhEngineCollisionEntry {
    Old: extend public box unmodifedBound() {
    New: extend public box unmodifiedBound() {

    Old: extend public Transform unmodifedTransform() {
    New: extend public Transform unmodifiedTransform() {
}

The public function box unmodifedBoundIncludingChildren(MhEngineBoxEntry entry, MhEngine engine) has been renamed to box unmodifiedBoundIncludingChildren(MhEngineBoxEntry entry, MhEngine engine).

Old: public box unmodifedBoundIncludingChildren(MhEngineBoxEntry entry, MhEngine engine) {
New: public box unmodifiedBoundIncludingChildren(MhEngineBoxEntry entry, MhEngine engine) {

MhAlignLoadsToAisleFunction changes

The method box unmodifedLocalBoundIncludingChildren(MhEngineEntry entry, Transform t, MhEngine engine) has been renamed to box unmodifiedLocalBoundIncludingChildren(MhEngineEntry entry, Transform t, MhEngine engine).

public class MhAlignLoadsToAisleFunction extends MhSystemEngineFunction {
    Old: extend public box unmodifedLocalBoundIncludingChildren(MhEngineEntry entry, Transform t, MhEngine engine) {
    New: extend public box unmodifiedLocalBoundIncludingChildren(MhEngineEntry entry, Transform t, MhEngine engine) {
}

MhMasterLinkFinalizeFunction changes

Added new argument runMultiChildrenLink to this engine function. The purpose of this argument is to link nested bays/frames together (bays within bay, frames within frame). See "Multi-bay and multi-frame support" in New Features for more info.

public class MhMasterLinkFinalizeFunction extends MhSystemEngineFunction {
    /**
     * Run multi children link.
     */
    public Bool runMultiChildrenLink;

MhRowFillVoidEntriesFunction changes

Added new argument flattenedFill to this engine function. The purpose of this argument is for racking systems with multi-bay/multi-frame structure (see "Multi-bay and multi-frame support" in New Features for more info). Set this argument to true if you want to fill empty bay space depth-wise when you have a multi-bay. Control this argument with MhBayRowEngineBehavior.shouldFlattenRowForFill(symbol event="", Object env=null).

public class MhBayRowEngineBehavior extends MhEngineBehavior {
    /**
     * Should flatten row for fill voids?
     */
    extend public bool shouldFlattenRowForFill(symbol event="", Object env=null) {
        return true;
    }
}

We've also broken up the existing logic in fillVoidEntries(MhEngineEntryBlock block) into several new methods for easier override.

public class MhRowFillVoidEntriesFunction extends MhSystemEngineFunction {

    /**
     * Fill removed snappers void entries.
     */
    extend public void fillRemovedSnappersVoidEntries(MhEngineEntryBlock block) {
        ...
    }


    /**
     * Fill gaps between entries with void entries.
     */
    extend public void fillGapsVoidEntries(MhEngineEntryBlock block,
                                           sorted int->MhEngineVoidEntry[] voidEntries) {
        ...
    }

MhRowRemoveLoneFramesFunction changes

Added argument MhEngineEntry{} bayEntries to the method shouldRemoveEntry.

public class MhRowRemoveLoneFramesFunction extends MhSystemEngineFunction {
    Old: extend public bool shouldRemoveEntry(MhEngine engine, MhEngineEntry frameEntry) {
    New: extend public bool shouldRemoveEntry(MhEngine engine, MhEngineEntry frameEntry, MhEngineEntry{} bayEntries) {
}

MhBayConfigurationItem changes

Added argument SnapperFilter filter to the method getBay.

public class MhBayConfigurationItem extends MhStorageConfigurationItem {
    Old: extend public MhSnapper getBay() {
    New: extend public MhSnapper getBay(SnapperFilter filter) {
}

MhRowApplyAnimation changes

Added argument MhSnapperGroup group to the method applyPickedUpSnappers.

public class MhRowApplyAnimation extends MhSnapperApplyAnimation {
    Old: extend public void applyPickedUpSnappers(Snapper[] groupSnappers, Snapper firstS, Snapper first, box oldBound, bool needToRotateChildren) {
    New: extend public void applyPickedUpSnappers(MhSnapperGroup group, Snapper[] groupSnappers, Snapper firstS, Snapper first, box oldBound, bool needToRotateChildren) {
}

Config function changes

Added argument SnapperFilter childFilter to the public function basicConfigEq.

Old: public bool basicConfigEq(MhSnapper a, MhSnapper b) : inline {
New: public bool basicConfigEq(MhSnapper a, MhSnapper b, SnapperFilter childFilter=null) : inline {

Added argument SnapperFilter childFilter to the public function childrenConfigEq.

Old: public bool childrenConfigEq(MhSnapper a, MhSnapper b, function(mhConfigSortEntry, mhConfigSortEntry, Object):int sortFunc, Object env=null) {
New: public bool childrenConfigEq(MhSnapper a, MhSnapper b, function(mhConfigSortEntry, mhConfigSortEntry, Object):int sortFunc, Object env=null, SnapperFilter childFilter=null) {

These work together with MhStorageConfigBehavior now having a new method Snapper childrenFilter() that is used in the existing method configEq(MhSnapper a, MhSnapper b, Object env=null) to now be able to filter out specific children from the equality comparison.

Removed deprecated class MhUnitLoadOffsetBehavior

The class MhUnitLoadOffsetBehavior has been deleted as well as the global singleton mhUnitLoadOffsetBehavior.

As such, we have also updated MhRowAnimationInfo and removed the method Point unitLoadPopulateOffset(MhSnapper snapper) which used this removed class.

public class MhRowAnimationInfo extends CoreObject {

Removed:
    /**
     * Unit load populate offset.
     * Override here if you have different overhang values.
     */
    extend public Point unitLoadPopulateOffset(MhSnapper snapper) {
        for (MhUnitLoadOffsetBehavior b in snapper.behaviors) {
            if (Point p = b.unitLoadPopulateOffset(snapper, configuration())) {
                return p;
            }
        }
        return null;
    }
}

MhBayEditorMeasurementsBehavior changes

Removed method void removeOldMeasurements(Space space) as it is not used.

public class MhBayEditorMeasurementsBehavior extends MhBehavior {

    /**
     * Remove old measurement.
     */
    extend public void removeOldMeasurements(Space space) {
        for (s in space.?snappers)  if (s in MhBayEditorMeasureDimension) space.remove(s);
    }
}

This logic already exists in MhBayEditConfiguration and this class handles the removal and insertion of dimensions (e.g. re-inserting dimensions when pulling props from snappers).

public class MhBayEditConfiguration extends MhStorageEditorConfiguration {

    /**
     * Remove old measurement.
     * Will be added on validate.
     */
    extend public void removeOldMeasurements(Space space) {
        SpaceSelection sel = space.?selection;
        for (MhBayEditorMeasureDimension s in space.?snappers) {
            if (!s.isActive) continue;
            if (s in sel) sel.remove(s);
            space.undoableRemove(s);
        }
    }


    /**
     * Pull props from snappers.
     */
    public void pullPropsFromSnappers() {
        removeOldMeasurements(space);

        for (s in snappers) {
            forChildrenRecursive(MhSnapper c in s) {
                if (c.isBay and hasRealConfig(c)) {
                    pullPropsFromSnapper(c);
                    insertMeasurements(c, space);
                }
            }
        }
    }
}

MhStorageEditorConfiguration changes

Updated interface of method Object{} pullPropsFromSnapper. The argument MhSnapper snapper has been widened to Snapper snapper.

public class MhStorageEditorConfiguration extends MhSystemConfiguration {
    Old: extend public Object{} pullPropsFromSnapper(MhSnapper snapper, Object env=null) {
    New: extend public Object{} pullPropsFromSnapper(Snapper snapper, Object env=null) {
}

MhStorageEditorItem changes

Updated interface of method MhSnapper{} applyToSnappers. The return value MhSnapper{} has been widened to Snapper{}.

public class MhStorageEditorItem extends MhSystemConfigurationItem {
    Old: extend public MhSnapper{} applySnappers(Space space, CoreProperty property=null) {
    New: extend public Snapper{} applySnappers(Space space, CoreProperty property=null) {
}

MhSystemConfiguration changes

The interface of various methods in this class have been updated such that their arguments MhSnapper or MhSnapper{} have been widened to Snapper or Snapper{}. See below for the full list.

public class MhSystemConfiguration extends CoreObject {

            forChildren(MhSnapper c in root) if (c.isBay) { rotated  = c.rot != 0deg; break; }
            Snapper[] snappers = sel.snappers.seq;

    Removed: public Rect systemRect;
}

public class MhRowRemoveLoneFramesFunction extends MhSystemEngineFunction {
    Removed: extend public bool shouldRemoveEntry(MhEngine engine, MhEngineEntry frameEntry) {
    New: extend public bool shouldRemoveEntry(MhEngine engine, MhEngineEntry frameEntry, MhEngineEntry{} bayEntries) {
}

    for (entry in insertEntries) {
        ... // insert snapppers code
        insertedEnv = inserted(insertSnapper, insertedEnv, sel);
    }

        if (insertedEnv) insertedEnv.owner.invalidateBehaviorsIfRequired(sSnapperInserted, insertedEnv);
        if (sel) space.select(sel);

MyRowChildWidthChangePropagateFunction changes

Removed field propagateFrames. It was used to block propagating width changes to frame entries. This ability has now been moved out to a new method bool shouldPropagateToEntry(MhEngineEntry entry, MhEngineEntry refEntry) to better control which entry we propagate to.

public class MyRowChildWidthChangePropagateFunction extends MyRowChildChangePropagateFunction {
    Removed: public Bool propagateFrames;

    /**
     * Props.
     */
    public props : cached=true {
        Removed: "propagateFrames";
    }


    Added:
    /**
     * Should propagate to entry?
     */
    extend public bool shouldPropagateToEntry(MhEngineEntry entry, MhEngineEntry refEntry) {
        return refEntry.isBay and entry.isBay;
    }

Propagation changes and alignment of row's children

The propagation mechanism within the racking system has undergone minor revisions. Previously, propagation functions would attempt to reposition the row based on the directional vector of the noticer or refEntry, aiming to maintain alignment across operations. However, this approach proved limiting in multi-bay or multi-frame configurations, where entries within the same row may have differing orientations. Moreover, the previous behavior introduced unnecessary overhead by performing additional row movements solely for alignment purposes.

The rationale behind these changes is to ensure that updates and propagation to affected snappers occur prior to any row adaptation or alignment. This sequencing improves clarity and control over the propagation process, allowing adjustments to be applied more predictably.

MhBayRowEngineBehavior changes

During depth propagation changes, when the system collecting snappers needed to be propagated, the method now will only try to populate affected snappers that will get the changes instead of having additional filter during function execution to filter out non-propagatable snappers.

    /**
     * Append propagation for row children?
     */
    extend public void appendPropagationRowChildren(MhSnapper row, MhSnapperChangedEnv env, str key, MhSnapper{} res) {
	    if (key == "d") {
	        MhSnapper owner = env.owner;
	        if (!owner.isBay and !owner.isFrame) return;

    	    ?MhSnapper parent = owner.parent;
	        Transform t = parent.?isMulti ? parent.?toSpaceTransform() : null;
	    
    	    forChildrenRecursive(MhSnapper c in row) {
		        if (c.isFrame or c.isBay) {
    		        if (!t) {
			            res << c;
		            } else if (c.shapeBound.d == env.oldValue.safeDouble) {
    			        point p = point0.transformed(c.toSpaceTransform() - t);
			            if (p.y == env.lastPos.y) res << c;
		            }
		        }
	        }
	    }
    }

As for the function arguments, the flag moveRow is set to false by default. We're expecting only to update row position and shape during MhRowAlignToChildrenFunction and MhRowUpdateShapeFunction.

	  case "rowChildWidthPropagate", "rowChildDepthPropagate", "rowChildHeightPropagate" : {
	      if (env as MhSnapperChangedEnv) {
		  SnapperSet rows();
		  for (s in propagatingRows(snapper, env)) {
		      // should probably handle aisles in the aisle/flue gap engine behavior.
		      //if (s.rootParent.isAisle) continue;
		      rows << s;
		  }
		  
		  return props { snapper=snapper, noticer=env.owner,
				 rows=rows,
				 moveRow=false };
				 //moveRow=animation.?isStretchAnimation() };
	      }
	  }

MyRowChildWidthChangePropagateFunction changes

Row child propagation will no longer implicitly trigger row movement. Instead, during width propagation, the function now attempts to reposition the propagated entry based on the directional vector of the refEntry. This adjustment clarifies the function’s intent by explicitly aligning movement behavior with reference-based directionality.

public class MyRowChildWidthChangePropagateFunction extends MyRowChildChangePropagateFunction {
    public Object exec() {
        ...

	    double diff = refEntry.w - e.w;
	    e.setW(refEntry.w);

	    angle eRot = e.toSpaceTransform(engine).rot.yaw;
	    if (eRot != rot) {
	        // Get the sign direction to move this entry.
	        double v = eRot.v - rot.v; v /= |v|;
	        if (refEntry.pDiff == point0) {
		        e.move((v*diff, 0, 0));
	        }
	    } else {
	        e.move(refEntry.pDiff);
	    }   
        ...
    }

MyRowChildDepthChangePropagateFunction changes

Similarly, the depth propagation function will no longer initiate row movement by default during propagation. To streamline its execution and clarify its intended behavior, a new method has been introduced and to opt out from this new approach, please set the return type for this useNewPropagate to false.

public class MyRowChildDepthChangePropagateFunction extends MyRowChildChangePropagateFunction {
    /**
     * Return true if use new depth propagate.
     */
    extend public bool useNewPropagate() {
	    return true;
    }


    /**
     * Propagate depth.
     */
    extend public void propagateDepth2(MhEngine engine, Snapper{} set, MhEngineRowChildEntry refEntry) {
	    MhEngineEntry rootParent = refEntry.rootParent(engine);
	    Transform parentT = refEntry.parent().toSpaceTransform(engine);
	    box refB = refEntry.bound();
	
	    for (MhSnapper s in set) {
	        ?MhEngineBoxEntry entry = engine.entry(s);
	        if (!mhFrameOrBayEntryFilter.accepts(entry)) continue;
	    
	        entry.setD(refEntry.d);

	        if (entry.rootParent(engine) == rootParent) {
		        box b = entry.localBound();
		        b.transform(entry.toSpaceTransform(engine) - parentT);
		        double diff = b.p0.y - refB.p0.y;
		        entry.move((0, -diff, 0));
	        }
	    }
    }

With these changes, the depth propagation function will no longer attempt to rearrange deep racking frame configurations. Its execution is now limited strictly to applying depth changes, minimizing unnecessary operations. Consequently, extensions utilizing deep racking frame setups must explicitly exclude these frames from propagation by applying the following filter when collecting affected objects.

public class DrBayRowEngineBehavior extends MhBayRowEngineBehavior {
    /**
     * Propagating filter.
     */
    public SnapperFilter propagatingFilter(MhSnapper noticer, str key) {
	    SnapperFilter res = super(..);
	    if (key == "d") {
	        if (noticer.isFrame) { // Exclude selection snappers from propagate.
		        return makeCombinedFilter(res, NotSnapperFilter(CurrentSelectionFilter()));
	        } else {
                // Added this filter so depth change will not be applied to the frame.
		        return makeCombinedFilter(res, NotSnapperFilter(frameFilter)); 
	        }
	    }
	    return res;
    }

MhRowChildrenAlignFunction changes

The current alignment implementation is no longer compatible with the newly introduced multi-bay and multi-frame configurations together with non-movable row during propagation. With that, we introduced new concept in the MhRowChildrenAlignFunction class to anchor the affected object and only push next or previous objects while maintaining the position of changed object.

X-axis alignment:

    /**
     * Align X.
     */
    extend public void alignX(sorted double->(MhEngineEntry[]) groupedEntries) {
	    // This is anchor index.
	    int index = {
	        if (ignoreAnchor.?v) result 0;
	        for (k, entries in groupedEntries, index=i) {
		        for (MhEngineBoxEntry e in entries) {
    		        if (e in tempList) ?e = tempList.get(e);
    		        if (e.wDiff != 0) result i;
	    	    }
	        }
	        result 0;
	    };

        ...

	    for (x in xs, start=index + 1) {
            // Push objects to the right of index
	    }
	
	    for (x in xs, reverse, start=index - 1) {
            // Push object to the left of index.
	    }
    }

Y-axis alignment:

    /**
     * Align Y.
     */
    extend public void alignY(sorted double->(MhEngineEntry[]) groupedEntries) {
	    // This is anchor index.
	    int index = {
	        if (ignoreAnchor.?v) result 0;
	        for (k, entries in groupedEntries, index=i) {
		        for (MhEngineBoxEntry e in entries) {
		            if (e in tempList) ?e = tempList.get(e);
		            if (e.dDiff != 0) result i;
		        }
	        }
	        result 0;
	    };
	
	    double[] xs = groupedEntries.keys;
	    box bound;
	    for (e in groupedEntries.get(xs[index])) if (first) bound = e.bound; else bound += e.bound;

        // Will prioritize to align on the object that changed.
    }

These alignments now can also be performed on different groups (blocks). All the populated entries of the row can be grouped into distinct blocks based on their y-position. This grouping by default will be conditional, only done if a difference in the y-bound of entries at the same x-position is found between entries of the same classification. However the grouping can be always done or always skipped, controlled with the groupByY argument and Bool shouldGroupByY() method. There may be cases where you would want to turn off this grouping, such as deep racking implemented with a non-multiframe structure (one row owns multiple child frames).

    /**
     * Align rows. 
     */
    extend public void alignRows(MhEngineRowEntry row) {
        ...
        if (MhSystemEngineEnvironment env = systemEnvironment()) {
            MhEngineEntryBlock[] blocks = env.getPopulatedBlocks(snapper);
            MhEngineEntryBlock[] blocksToAlign = blocksToAlign(blocks);
            populateDistancesBetweenBlocks(blocksToAlign);
            
            for (block in blocksToAlign, index=i) {
                sorted double->(MhEngineEntry[]) groupedEntries();

                MhEngineEntry[] entries = mhYSortedEntries(block.entries, unmodify=true);
                // Group entries based on x-location.
                for (e in entries) {
                    ...
                    groupedEntries.put(x, es);
                    es << e;
                }

                // Align along x-axis.
                alignX(groupedEntries);

                // Align along y-axis.
                alignY(groupedEntries);
            }

            // Align filtered imported block.
            alignBlocks(blocksToAlign);
            
            // Move back to original parent.
            resetToParentTransform(engine, row, blocksToAlign);
        }
    }


    /**
     * Blocks to be align.
     */
    extend public MhEngineEntryBlock[] blocksToAlign(MhEngineEntryBlock[] populated) {
        ...        
        MhEngineEntry[] entries();
        bool grpByY = false;
        Bool forceGroupByY = shouldGroupByY();
        if (forceGroupByY) grpByY = forceGroupByY.v;

        // Collecting all populated entries into a seq.
        for (block in populated) {
            for (e in block.entries) {
                ...
            }
        }

        sorted double->(MhEngineEntry[]) groupedEntries();
        // First pass to create all groups.
        for (MhEngineBoxEntry e in entries) {
            ...
        }

        // Second pass to add other entries that overlap with y to group.
        if (grpByY) {
            ...
        }

        // Create groups sorted by x.
        for (y, es in groupedEntries, index=i) {
            ...
        }
        ...
    }


    /**
     * Should group by y-pos?
     */
    extend public Bool shouldGroupByY() {
        return groupByY;
    }

MhRowAlignToChildrenFunction and MhRowUpdateShapeFunction changes

All logic in this class has been moved up to more generic class to be used by multi-bay and multi-frame as well.

    New: public class MhAlignToChildrenFunction extends MhSystemEngineFunction {
    New: public class MhUpdateShapeFunction extends MhSystemEngineFunction {

MhSystemPopulateFunction changes

Removed argument int adders from method buildRows.

public class MhSystemPopulateFunction extends MhSystemEngineFunction {

    Old: extend public void buildRows(MhSystemEngineEnvironment env, rect r, int adders) {
    New: extend public void buildRows(MhSystemEngineEnvironment env, rect r) {
}

This argument can be replaced with the following code in this method.

    /**
     * BuildOfRows
     */
    extend public void buildRows(MhSystemEngineEnvironment env, rect r) {
        ...
        int adders = info.aisleCount(config);
        if (adders < 0) return;
        ...
    }

Removed class MhCantileverFrameChildAdjustToBehavior

The class MhCantileverFrameChildAdjustToBehavior has been deleted as well as the global singleton mhCantileverFrameChildAdjustToBehavior. The logic within this class has been incorporated into parent class MhChildAdjustToBehavior.

Removed:
public class MhCantileverFrameChildAdjustToBehavior extends MhChildAdjustToBehavior {

    /**
     * Child intersect pos.
     * Position used to find closest snap alternative.
     */
    public point childIntersectPos(MhSnapper owner, MhSnapper child, Object env=null) {
        if (isArm(child)) { // Maintain z-pos of arm regardless of its bound.
            box bound = child.localBound;
            point center = bound.center.transformed(mhTransform(child.pos, child.rot));
            return (center.x, center.y, child.pos.z);
        }

        return super(..);
    }
}

class CustomSpecOption

See cm.abstract.part section in 16.5 New Features migration guide for new CustomSpecOption class documentation .

class AbsPart

Old Pricing API

The following functions are now part of the old pricing system. They are still available for backwards compatibility (except basePrice which has been overloaded in core Part). Migration to the new pricing API should happen as soon as possible. The new pricing API is introduced in v16.5 and documented in the cm.core.part.Part documentation.

public double customListPrice(bool includeChildren=false, str currency=null, Space space=null) {}
extend public double specialListPrice(double listPrice) {}
extend public Double baseOptionPrice() {}
extend public Double specialOptionPrice() {}
extend public double optionSpecialUpcharge() {}
extend public Double upcharge() {}

Old: extend public double basePrice() {}
New: extend public double basePrice(bool includeChildren=false, Space space=null, bool translatePrice=true) {}

class CustomOptionSpecial

See cm.abstract.part section in 16.5 New Features migration guide for new CustomOptionSpecial class documentation .

class SpecOption

Changed: extend public double upcharge(ProdPart owner=null) {}

The upcharge method for SpecOption has been extended to support:

• A broader Part owner parameter (instead of only ProdPart).
• Currency translation via a new translatePrice flag and Space context.

Old: extend public double upcharge(ProdPart owner=null) {}
New: extend public double upcharge(Part owner=null, Space space=null, bool translatePrice=false) {}

Old → New behavior

Old:

• Logic:
  • Started from the option’s price.
  • Applied any applicable OptionSpecial adjustments (replace or add).
  • Returned the resulting value.
• Only accepted ProdPart as the owner.
• No currency translation was possible.

New:

• Logic:
  • Same base calculation (price + special adjustments).
  • If translatePrice=true and the owner uses a non-default currency, the result is converted using owner.translatePrice(...).
• No longer assumes ProdPart owner.

class OptionSpecial

The following fields and methods have been added and changed in the OptionSpecial class:

// FIELDS
Added: public int level;
Added: public int sequence;

// METHODS
Added: public void copy(PartSpecial special) {}
Added: extend public str optStr=(str value) {}
Added: extend public str optDescStr=(str value) {}
Added: extend public int level=(int value) {}
Added: extend public int sequence=(int value) {}
Added: extend public Part originalPart=(Part value) {}
Added: extend public str originalOptStr=(str value) {}

// UPDATED
Old: public constructor(str partNum, str descr, bool priceReplace, double amount|, str optStr, str optDescStr, Part originalPart, str originalOptStr) {}
New: public constructor(str partNum, str descr, bool priceReplace, double amount|, str optStr, str optDescStr, Part originalPart=null, str originalOptStr=null, int level=0, int sequence=-1) {}

public str flattenableKey() {
	StrBuf res(super());
	res << optStr 
		<< optDescStr 
New:	<< level 
New:	<< sequence
		<< originalPart 
		<< originalPart.specialsKey();
	return res.toS();
}

class ProdPart

Changed: final public SpecOption[] specOptions=(SpecOption[] newOptions) {} and extend public void appendSpecOptions(SpecOption[] newOptions) {}

Both specOptions and appendSpecOptions now accept a new boolean parameter invalidateOptionPrice (default: true). This works with the new option price caching mechanism by allowing the system to selectively invalidate the cached option price sum when spec options are modified.

Old: final public SpecOption[] specOptions=(SpecOption[] newOptions) {}
New: final public SpecOption[] specOptions=(SpecOption[] newOptions, bool invalidateOptionPrice=true) {}

Old: extend public void appendSpecOptions(SpecOption[] newOptions) {}
New: extend public void appendSpecOptions(SpecOption[] newOptions, bool invalidateOptionPrice=true) {}

Old → New behavior

Old:

• Option prices were not cached.
• Every time option prices were accessed, they were recalculated on the fly based on current spec options.
• No invalidation step was needed.

New:

• Option price totals are now cached
• When spec options are modified, invalidateOptionPriceSum() is triggered to ensure the cache stays correct
• Developers can pass invalidateOptionPrice=false to skip cache invalidation if they plan to manage it manually or delay recalculation.

Impact

• Performance improvement: frequent option price sum lookups no longer require full recalculation
• Cache management: introduces the concept of invalidating/regenerating option price sums as options change.
• Default safety: with the default true, cache stays consistent automatically — existing usage behaves as expected
• Advanced optimization: developers can set false during bulk option appends/updates, then explicitly trigger invalidation once, avoiding multiple regenerations.
• Migration note: developers should be aware that option pricing is no longer computed “live” — results are now cache-backed.

Other ProdPart Changes

• Added optional bool invalidateWorldPrice parameter to special functions
  • Allows control over invalidation of world pricing when making a special change
  • Originally invalidated world price on every special change
• Expanded special interfaces to accept PartOptionItems
  • Previously was exclusively accepted SpecOptions

Interfaces

Added: extend public void putOptSpecial(PartOptionItem opt, OptionSpecial special, PropObj s=null, bool invalidateWorldPrice=true) {}

Old: extend public void generateOptAdjustmentSifRows(SpecOption opt, str[] lines) {}
New: extend public void generateOptAdjustmentSifRows(PartOptionItem opt, str[] lines) {}

Old: extend public str optSpecialKey(SpecOption opt) {}
New: extend public str optSpecialKey(PartOptionItem opt) {}

Old: extend public OptionSpecial getOptSpecial(SpecOption opt, PropObj s=null) {}
New: extend public OptionSpecial getOptSpecial(PartOptionItem opt, PropObj s=null) {}

Old: extend public void removeOptSpecial(SpecOption opt, PropObj s=null) {}
New: extend public void removeOptSpecial(PartOptionItem opt, PropObj s=null, bool invalidateWorldPrice=true) {}

Old: extend public void removeOptSpecials(PropObj s=null) {}
New: extend public void removeOptSpecials(PropObj s=null, bool invalidateWorldPrice=true) {}

Old: extend public void removeAllSpecials(PropObj s=null) {}
New: extend public void removeAllSpecials(PropObj s=null, bool invalidateWorldPrice=true) {}

class ProdPartGridBuilderEnv

Added: extend public GridCell getOptionRowCell(PartOptionItem opt, int columnIdx, Part part=null) {}

• Gets option row cell for parameter values
• Parameters:
  • PartOptionItem opt: Option for row to get cell for (can be null)
  • int columnIdx: Column index to get cell for
  • Part part: Part owning option row to get cell for (can be null)
    • mainly utilized for acquiring option specials data

Behavior

• If opt is null or column index is out of bounds, returns getDefaultCell
• Otherwise, returns a cell for the option data associated with the column index
  • Assigns a background color to the cell by calling getCellBrush

Changed: extend public GridCell[] getOptionRowCells(SpecOption opt, ProdPart part=null) {}

Old → New behavior

Old:

• Directly returned a sequence of GridCells

New:

• Loops through columns, calling getOptionRowCell for each column and appending it to the returned GridCell sequence
• Allows for more flexibility when building option row cells

class OptionMakeSpecialDialog

Removed: public void onOKButtonClick(Object sender, Object args) {}

• This method was originally overridden to allow for returning an OptionSpecial type on OK button click
• The super class now calls generateSpecial to create the new special on OK button click

class QueryProdPartGridBuilderEnv

In 16.5, the ProdPartQueryDialogDataEnv has changed it's backing data structures, replacing the str->Part parts, int->str rowIDs, and str->str{} options maps with a single QueryRowData[] queryRows data sequence. Cell highlighting has also been introduced in the QueryDialog.

As a result, the following functions have been removed and added to QueryProdPartGridBuilderEnv.

Removed: public str rowIdentifier(Object data) {}
Added: public GridCell[] getRowCells(Object data) {}
Added: public Brush getCellBrush(Object data, int columnIdx) {}

class ProdPartQueryDialogBehavior

New Add Option Feature

With the addition of the new "Add Option" feature in the query dialog and the new data structure of QueryDialogDataEnv, changes in ProdPartQueryDialogBehavior have been made.

• Overrides of top window related functions:
  • initTopWindow to utilize new ProdPartQueryControlWindow for ProdParts
  • initTopWindowEvents to handle events from ProdPartQueryControlWindow
  • onAddOptionBtnClicked to handle add option button click from ProdPartQueryControlWindow
• Overrides of new getCustomSpecialDialog function:
  • Overidden to return custom special dialog for a ProdPart option
• Modified interfaces to support new index-driven data model (vs. previous str-based data model)
  • Shown below

The following interface additions, removals, and changes have been made in ProdPartQueryDialogBehavior:

// ADDED/REMOVED INTERFACES
Added: public SubWindow initTopWindow(QueryDialog parent) {}

New: public DialogWindow getSpecialDialog(QueryDialog dialog, int row) {}

Old: extend public DialogWindow getOptionSpecialDialog(QueryDialog dialog, str id |, Part part) {}
New: extend public DialogWindow getOptionSpecialDialog(QueryDialog dialog, int row |, Part part) {}

class ProdPartQueryDialogDataEnv

With the new data structure of QueryDialogDataEnv, changes in ProdPartQueryDialogDataEnv have been made.

• New data building functions:
  • buildQueryRowData: Overridden to support ProdPart option rows
  • buildPartOptions: Created to build part option rows for ProdParts
  • createPartRowData: Overridden to create QueryProdPartRowDatas for ProdPart rows
  • createOptionRowData: Created to build QueryOptionRowDatas for ProdPart option rows
  • refreshQueryRowData: Overridden to optimize rebuild process

  • No longer needed with new data structure
  • Option rows are stored in new QueryRowData[] queryRows as QueryOptionRowDatas
• Removed old data building/manipulation functions:
  • setParts: No longer needed with new data structure
  • buildParts: ''
  • buildPartOptions: ''
  • getPartIDFromOptionID: ''
  • getPartFromOptionID: ''
  • getSpecial: Logic has been moved to new QueryRowData type

// ADDED INTERFACES
Added: public void buildQueryRowData(Part[] parts=null) {}
Added: extend public void buildPartOptions(QueryRowData partRow) {}
Added: public QueryRowData createPartRowData(Part part) {}
Added: extend public QueryRowData createOptionRowData(SpecOption option, QueryRowData partRow) {}
Added: public void refreshQueryRowData() {}

// REMOVED INTERFACES
Removed: public str->str{} options;

Removed: extend public void buildPartOptions(str partRowID, ProdPart part) {}
Removed: extend public void buildPartOptions(ProdPart part) {}
Removed: public PartSpecial getSpecial(str id) {}
Removed: public void putSpecial(str id, PartSpecial special) {}
Removed: public void removeSpecial(str id) {}
Removed: extend public str getPartIDFromOptionID(str id) {}
Removed: extend public Part getPartFromOptionID(str id) {}

ElevArrowG2

The field elevSpace has changed its type from Space to a more specific ElevSpace. This reduces the need for casting.

Old: public Space elevSpace : stream=null, copy=null;
New: public ElevSpaceG2 elevSpace : stream=null, copy=null;

# Example
Old: if (elevSpace as ElevSpaceG2) {
New: if (elevSpace) {

ElevAutoSnapperEnvG2 changes

A new field bool locationLocked has been added. As such, the constructor has been updated to set this field.

public class ElevAutoSnapperEnvG2 extends PropObj {
    Old: public constructor(str key, point pos, orientation rot) {
    New: public constructor(str key, point pos, orientation rot, bool locationLocked=false) {
}

The class ElevAutoDimEnvG2 has also had its constructor updated to set this field.

public class ElevAutoDimEnvG2 extends ElevAutoSnapperEnvG2 {
    Old: public constructor(str key, point p0, point p1, double d, UserTextStyle ts, UserDimensionStyle ds, str prefix="", bool allowDimSelect=true) {
    New: public constructor(str key, point p0, point p1, double d, UserTextStyle ts, UserDimensionStyle ds, str prefix="", bool allowDimSelect=true, bool locationLocked=false) {
}

UnitLoad changes

Moved a method Transform loadDirectionXForm() down from UnitLoadPallet to UnitLoad.

public class UnitLoad extends CoreObject {

    /**
     * Transform for load direction.
     */
    extend public Transform loadDirectionXForm() {
        return null;
    }
}

Updated interface of method bool eq. Added a new optional argument str->Object args=null.

public class UnitLoad extends CoreObject {
    Old: extend public bool eq(UnitLoad m) {
    New: extend public bool eq(UnitLoad m, str->Object args=null) {
}

At the moment, only one value in args is used in this method, "propsToIgnore"->str[] which can be used to ignore specific props in specific equality checks. It serves as an alternative to overriding str[] propsIgnoreEqCheck() which will ignore the props for all equality checks of that UnitLoad.

public class UnitLoad extends CoreObject {

    /**
     * Equal?
     */
    extend public bool eq(UnitLoad m, str->Object args=null) {
        ...
        ?str[] propsToIgnore = args.?get("propsToIgnore");
        if (propsToIgnore) propsToIgnore += propsIgnoreEqCheck();
        else propsToIgnore = propsIgnoreEqCheck();
        for (k in propDefs.order) {
            if (k in propsToIgnore) continue;
            ...
        }
    }
}

As a result of this change, we have also removed the function bool unitLoadEq(UnitLoad unitLoad, UnitLoad l). Previous calls to this function have been replaced by directly calling the eq(UnitLoad m, str->Object args=null) method.

Removed:
public bool unitLoadEq(UnitLoad unitLoad, UnitLoad l) {
    return unitLoad.eq(l);
}

Example usage:
unitLoad.eq(l);

Added a new method MhPalletLoadSide getLoadDirection() so that UnitLoad can return a direction value. This value was previously only used in UnitLoadPallet but now there is an interface so that other unit load classes can return a direction as well.

public class UnitLoad extends CoreObject {

    /**
     * Get load direction.
     */
    extend public MhPalletLoadSide getLoadDirection() {
        return null;
    }
}

UnitLoadPreviewSnapper changes

Updated the interface of method Primitive3D loadDir3D. The argument UnitLoadPallet pallet has been widened to UnitLoad ul.

public class UnitLoadPreviewSnapper extends UnitLoadSnapper {
    Old: extend public Primitive3D loadDir3D(UnitLoadPallet pallet) {
    New: extend public Primitive3D loadDir3D(UnitLoad ul) {
}

Previous implementations of loadDir3D(UnitLoadPallet ul) would often access a direction value mhPalletLoadSide that was previously only available to UnitLoadPallet. You can switch those calls over to UnitLoad.getLoadDirection() instead without needing to cast to UnitLoadPallet.

Example:
public class UnitLoadPreviewSnapper extends UnitLoadSnapper {

    /**
     * Load Direction Arrow 3D.
     */
    extend public Primitive3D loadDir3D(UnitLoad ul) {
        MhPalletLoadSide dir = ul.getLoadDirection();
        if (!dir) return null;
        ...
    }
}

UnitLoadDialog changes

Updated the interface of method void zoomToPreview. The argument Snapper s has been removed. The reason for this is we have switched the previous implementation of zooming in to a specific snapper's bound to a zoomExtents of the view.

public class UnitLoadDialog extends DialogWindow {

    Old:
    extend public void zoomToPreview(Snapper s) {
        if (!preview3D or !preview3D.space) return;
        if (!s) {
            for (ns in preview3D.space.snappers) {
                s = ns;
            }
        }

        if (!s) return;

        disableUndo {
            preview3D.zoomBound(s.bound);
        }
    }


    New:
    extend public void zoomToPreview() {
        if (!preview3D or !preview3D.space) return;
        if (preview3D.space.snappers.empty) return;
        preview3D.zoomExtents(undoable=false);
    }
}

UnitLoadTemplateSelectorDialog changes

Updated the interface of method void zoomToPreview. The argument Snapper s has been removed. The reason for this is we have switched the previous implementation of zooming in to a specific snapper's bound to a zoomExtents of the view.

public class UnitLoadTemplateSelectorDialog extends DialogWindow {

    Old:
    extend public void zoomToPreview(Snapper s) {
        if (!preview3D or !preview3D.space) return;
        if (!s) {
            for (ns in preview3D.space.snappers) {
                s = ns;
            }
        }

        if (!s) return;

        disableUndo {
            preview3D.zoomBound(s.bound);
        }
    }


    New:
    extend public void zoomToPreview() {
        if (!preview3D or !preview3D.space) return;
        if (preview3D.space.snappers.empty) return;
        preview3D.zoomExtents(undoable=false);
    }
}

Renamed class MhUserSettings to UnitLoadUserSettings

The class MhUserSettings has been renamed to UnitLoadUserSettings.

The global function MhUserSettings mhUserSettings() has been replaced by UnitLoadUserSettings ulUserSettings().

Old: public class MhUserSettings extends UserSettings {
New: public class UnitLoadUserSettings extends UserSettings {

Old: public MhUserSettings mhUserSettings() {
New: public UnitLoadUserSettings ulUserSettings() {

Removal of StdApplicationManager

The class StdApplicationManager and ApplicationManager has been combined into a single class now. This should simplify existing code by eliminating the need to cast (a sample example is listed).

Old: public class StdApplicationManager {
New: public class ApplicationManager {

# Example
Old: app = appManager.StdApplicationManager.?getApplication(id) ?? application;
New: app = appManager.?getApplication(id) ?? application;

notifyStrip.cm

Added new arguments to addButton method to control the standard brush and the hover brush of buttons in the notify strip.

Old: extend public NotifyPartButton addButton(str text, str tooltip=null,
					      function(Control, NotifyButtonArgs) callback=null,
					      Object callbackArg=null,
					      bool closeAfterClick=false,
					      Timespan snoozeAfterClick=null,
					      function():Timespan snoozeAfterClickCallback=null,
					      bool highlight=false,
					      bool triggerCallbackOnShow=false,
					      Image image=null)
New: extend public NotifyPartButton addButton(str text, str tooltip=null,
					      function(Control, NotifyButtonArgs) callback=null,
					      Object callbackArg=null,
					      bool closeAfterClick=false,
					      Timespan snoozeAfterClick=null,
					      function():Timespan snoozeAfterClickCallback=null,
					      bool highlight=false,
					      bool triggerCallbackOnShow=false,
					      Brush customStdBrush=null,
					      Brush customHoverBrush=null,
					      Color customLabelColor=null,
					      Image image=null)

notifyMessage.cm

Added new arguments to the constructor of NotifyPartButton to store the standard brush and the hover brush when creating buttons for the notify strip.

Old: public constructor(NotifyMessage message, str text,
		       str tooltip=null,
		       function(Control button, NotifyButtonArgs args) callback=null,
		       Object callbackArg=null,
		       bool closeAfterClick=false,
		       // MergeTODO : add a close callback here in 8.0
		       Timespan snoozeAfterClick=null,
		       function():Timespan snoozeAfterClickCallback=null,
		       bool highlight=false,
		       bool triggerCallbackOnShow=false,
		       Image image=null)
New: public constructor(NotifyMessage message, str text,
		       str tooltip=null,
		       function(Control button, NotifyButtonArgs args) callback=null,
		       Object callbackArg=null,
		       bool closeAfterClick=false,
		       // MergeTODO : add a close callback here in 8.0
		       Timespan snoozeAfterClick=null,
		       function():Timespan snoozeAfterClickCallback=null,
		       bool highlight=false,
		       bool triggerCallbackOnShow=false,
		       Brush customStdBrush=null,
		       Brush customHoverBrush=null,
		       Color customLabelColor=null,
		       Image image=null)

class Entity

Force initAfterInstantiate() to call ancestor super class in order to ensure gid protocol is always respected.

Old: extend public void initAfterInstantiate() {
New: extend public void initAfterInstantiate() : require super {

copySelection.cm

The restoreCleanup() function has been removed. Its primary functionality made unexpected modifications to the snapper being copied. As a replacement to calling restoreCleanup(), use if (Space space = getSpace()) space.select(SpaceSelection(this)); to restore the original selection.

If modifications to the original snapper is required for some reason (which is highly discouraged), consider making use of the snapper functions beforeUserCopied(..) or userCopied(..) instead.

Removed: final public void restoreCleanup() {

CET QL

In the class CetQLWorldManager, the method destroySpace has been renamed to removeSpace.

Old: extend public void destroySpace(Space s) {
New: extend public void removeSpace(Space s) {

In the class CetQLSpaceManager, the field removeSnapperSet has been removed.

Old: public SnapperRef{} removeSnapperSet : deprecated;

SnapperRef

As SnapperRef has been reworked to also keeps track of the space guid to enforce greater consistency, we have a new and recommended way to construct a SnapperRef.

Old: public constructor(guid gid) {
Old: public constructor(Snapper z) {
New: public constructor(Snapper z, Space space) {

ToolbarModelItem

The access modifiers for field image has been changed, a new setter method is introduced.

Old: public Image image : copy=reference;
New: private Image image : copy=reference, public readable;
New: final public void setImage(Image i) {

class Space

A new function for invalidating ItemTags in a space has been added.

• Iterates ItemTags in bsp.singularities, calling invalidate(..) on each
• Iterates BlockSpaces, calling invalidateItemTags(..) on each

/**
 * Invalidate all item tags in BSP.
 */
extend public void invalidateItemTags(dirty2D flag2D=dirty2D.all) {
	for (ItemTag s in bsp.?singularities) s.invalidate(flag2D);
	
	for (BlockSnapper blockSnapper in snappers) {
		BlockSpace blockSpace = blockSnapper.block.?blockSpace;
		blockSpace.?invalidateItemTags(..);
	}
}

class BlockSpace

A new function for invalidating BlockSpace ItemTags has been added.

• Overidden from the super classes implementation
• Calls block.?updateOwners(..) after the invalidation has been done

/**
 * Invalidate all item tags in BSP.
 */
public void invalidateItemTags(dirty2D flag2D=dirty2D.all) {
	super(..);
	block.?updateOwners(recursive=false, excludedSpace=this, flag2D=flag2D, flag3D=dirty3D.none);
}

# CollFilesDialogResizer
Removed: resize
Removed: needUpdateOnResize

Added: resize0
Added: resize1

CollProjectTvItem

The constructor for CollProjectTvItem has been updated to always show customer information by default. Additionally, the constructor now allows optional configurations like bolding the labels for active projects and whether the tree view item itself should be clickable or not.

Old: public constructor(CollProjectInfo project,
                        bool showCustomer=false, 
                        bool showLastModified=true) {

New: public constructor(CollProjectInfo project,
                        bool showCustomer=true,
                        bool showLastModified=true,
                        bool boldActive=true,
                        bool allowClick=true) {

The following mouse operation handling methods have been removed as the tree view item no longer displays a CollProjectTVITag beside local CollabPro projects.

Removed: public bool enter(TreeViewMouseInfo mi) {}
Removed: public bool exit(TreeViewMouseInfo mi) {}
Removed: public bool move(TreeViewMouseInfo mi) {}

FilePageCollaboration

The following class field has been removed and dereferenced from the FilePageCollaboration dialog.

Removed: public Button refreshProjBtn;

As part of our efforts to standardize the layout and interface of CollabPro's file menu page, the following build and relayout methods have been removed. To further extend from the FilePageCollaboration dialog, additional customized build methods should be supplied by overriding the main build() method instead. For customized relayouts, they should be included by overriding the main relayout() method as well.

Removed: extend public void buildInfoSW() {}
Removed: extend public void buildContentSW() {}
Removed: extend public void buildButtons(Brush brush) {}
Removed: extend public void buildSearch(Brush brush) {}
Removed: extend public void relayoutInfoSW() {}
Removed: extend public void relayoutContentSW() {}

class DwgBsp

Removed an argument that was not used

Old: final public void endModify(ProgressDialog pd) {
New: final public void endModify() {

dwgDialog.cm

Old: public Snapper loadDwgFiles(Url[] files, DropFiles drop=null, Point dropSpacePos=null, Point pos=null, bool exception=false) {
New: public Snapper{} loadDwgFiles(Url[] files, DropFiles drop=null, Point dropSpacePos=null, Point pos=null, bool exception=false) {

class DwgDialog

Many interfaces have been changed to accommodate the new multi-select functionality. Most notably, a lot of functions now take a Snapper argument that they operate on instead of always operating on the selected DWG. This makes it possible to operate on individual DWGs in the selection when necessary.

The following interfaces that were used to get the currently selected DWG have been updated to return the set of all selected DWGs.

Old: package Snapper activeDwgSnapper : public readable;
Old: final public Snapper snapper() {
New: final public Snapper{} selection() {

Old: extend public DwgTvi selectedTvi() {
New: final public DwgTvi{} selectedTVItems() {

The following interface that was used to select a DWG has been updated to also handle appending to selection. The reason for it being 'smart' is that it is not a simple select. It can pop up a modal dialog and keep modified DWGs in selection even if removePrevious=true.

Old: final public void changeActiveDwg(Snapper s, bool rebuild=true) {
New: final public bool smartSelect(Snapper dwgSnapper, bool removePrevious=true, bool invokeCallback=true) {

To be able to select many DWGs at once the following interfaces have been added.

Added: final public bool smartSelect(Snapper{} dwgSnappers, bool removePrevious=true, bool invokeCallback=true) {
Added: final public bool smartSelect(str{} keys, bool removePrevious=true, bool invokeCallback=true) {

The dwgSnapperIsParent-field has been removed as it is no longer needed. To figure out if a tree view item is a parent it is possible check item in DwgParentTvi instead. Selected parent tree view items will not contribute to final public Snapper{} selection().

Removed: private bool dwgSnapperIsParent : public readable;

The following methods are deemed no longer needed and have been removed. There is no direct replacement for them.

Removed: final public void setScaleFromInsUnits(bool update=true) {
Removed: final public Snapper snapperFromItem(TreeViewItem item) {
Removed: final public str getUnitKey() {

The fileTreeViewChanged()-function has been removed. To update the file tree view, call updateFileTreeView or updateContent instead.

Removed: final public void fileTreeViewChanged() {

These methods can be replaced with methods with the same name on DwgCaptureSnapper.

Removed: final public bool sourceFileMissing() {
Removed: final public bool sourceFileOutOfDate() {

The isCaptureSnapper()-function has been removed. As a replacement, check snapper in DwgCaptureSnapper instead.

Removed: final public bool isCaptureSnapper() : inline {

The getDwgSource()-function has been removed. Use the getSource()-function on DwgSnapper or DwgCaptureSnapper instead.

Removed: final public Url getDwgSource() {

The getDwgRoot()-function has been removed. Use the getDwgRoot()-function in cm/core/dwg/dwg.interface.cm instead.

Removed: final public DwgRoot getDwgRoot() {

Old: private bool dwgSnapperHasMultipleCopies : public readable;
New: final public bool hasMultipleCopies(Snapper snapper) {
Old: extend public bool apply(Point pos=null, bool exception=false) {
New: extend public bool apply(Snapper snapper, Point pos=null, bool exception=false) {
Added: extend public bool apply(Snapper{} snappers, Point pos=null, bool exception=false) {

The functions below have been updated to return the loaded DWG snappers, in order to improve code readability. For the method that returned a bool, the new will return null if and only if it previously returned false.

Old: extend public bool loadDwgFile(Url file, bool xref=false, Window parent=null,
New: extend public Snapper loadDwgFile(Url file, bool xref=false, Window parent=null,

Old: final public void loadDwgFile(Url file, DwgRoot root, bool xref=false, bool exception=false, bool dragDrop=false) {
New: final public Snapper loadDwgFile(Url file, DwgRoot root, bool xref=false, bool exception=false, bool dragDrop=false) {

Old: final public void animate(Url file, bool repeat=true, Window parent=null, DropFiles drop=null, Point dropSpacePos=null) {
New: final public Snapper animate(Url file, bool repeat=true, Window parent=null, DropFiles drop=null, Point dropSpacePos=null) {

A Snapper argument has been added to replace uses of the activeDwgSnapper-field in the following methods. The argument expects either a DwgSnapper or a DwgCaptureSnapper.

Old: extend public bool importSettingsChanged() {
New: extend public bool importSettingsChanged(Snapper snapper) {

Old: final public DwgSnapper{} getXRefsNoInsert() {
New: final public DwgSnapper{} getXRefsNoInsert(Snapper snapper) {

Old: final public void groupActiveDwgSnapperWith(Snapper{} snappers) {
New: final public void groupDwgSnappers(Snapper main, Snapper{} snappers) {

Old: extend public int checkForChanges() {
New: extend public int checkForChanges(Snapper{} snappers=dwgDialog.?selection()) {

Old: final public void dropOnCursor(DropFiles drop, Point spacePos) {
New: final public void dropOnCursor(Snapper snapper, DropFiles drop, Point spacePos) {

Old: extend public void locateSnapper() {

Remove methods

Remove an item from the dwg dialog:

Old: extend public void removeSnapper(Snapper candidate, bool update=true, bool anySnapper=true) {
New: extend public void removeSnapperFromDialog(Snapper candidate, bool update=true) {

Remove item from space and dwg dialog:

Remove: extend public void removeSnapper() {

To remove from space use removeDwgSnapper(Snapper snapper) instead.

class DwgHideLayerOp

Renamed variable for clarity

Old: public int64{} l;
New: public int64{} layers;
Old: public constructor(DwgSnapper dwg, int64 l, bool undo=true) {
New: public constructor(DwgSnapper dwg, int64{} layers, bool undo=true) {

class DwgLayersCard

Many methods now take an argument to specify the DwgSnapper being edited.

Old: final public void setSnappableLayer(DwgLayer z, bool v) {
New: final public void setSnappableLayer(DwgLayer z, bool v, Snapper snapper) {
New: final public void setSnappableLayer(DwgLayer z, bool v, Snapper{} snapper) {

Old: final public void setLayerColor(DwgLayer layer, color c, bool ignoreUserMaterial) {
New: final public void setLayerColor(DwgLayer layer, color c, bool ignoreUserMaterial, Snapper snapper) {

One method was given the responsibility of finding all snappers being updated itself, since it needed this to create the proper undo steps:

Old: final public void setVisibleLayer(DwgLayer z, bool v, bool updateVisibility=true) {
New: final public void setVisibleLayer(bool v, DwgLayerTreeViewItem clickedItem, bool updateVisibility=true) {

Instead use

final public DwgSnapper{} insertAllXRefs(Window parent=null, Space space=null, bool relocate=true, bool insert=true, Bool xRefImportCancelled=null) {

class DwgPropertiesCard

Some interfaces have been changed from public to private as they are not intended to be used outside of DwgPropertiesCard.

Removed: final public void setRawScale() {

The reBuild()-function is no longer needed, since updateContent() now updates all UI elements.

Removed: final public void reBuild() {

The setScaleFromInsUnits()-function is no longer needed and has been removed.

Removed: final public void setScaleFromInsUnits(bool update=false) {

Old: extend public void fitToPaper() {

New: public void fitToPaper(Snapper snapper, Space insertSpace=null) {
New: public void fitToPaper(Snapper{} snappers=null, Space insertSpace=null) {

class DwgHideLayerOp

The undo operation can now undo multiple layers at once.

Old: public int64 l;

Old: public constructor(DwgSnapper dwg, int64 l, bool undo=true) {
New: public constructor(DwgSnapper dwg, int64{} layers, bool undo=true) {

class DwgExporter

renamed styles map and made it package

Old: public str->DwgStyle styles();
New: package str->DwgStyle nameStyleMap();

class FavoriteCache

Return DibImage for the use of SaveFavoriteDialog and BrowseFavoriteDialog

Old: final public MemoryImage thumbnail(Url location) {
New: final public DibImage thumbnail(Url location) {

class FavoriteInfo

Change to store DibImage for the use of FavoriteCache, reducing GDI Object usage.

Old: public MemoryImage image;
New: public DibImage image;

favorites.cm

MemoryImage to be casted to DibImage and destroyed explicitly to reduce GDI Object usage.

Old: public MemoryImage favoriteThumbnail(Url location, bool progress=false) {
New: public DibImage favoriteThumbnail(Url location, bool progress=false) {

class APath2D

The area method in APath2D has now been implemented.

public double area() {

Therefore, this approximate area method has been removed.

Removed: extend public double area(angle arcResolution=15 deg, double deviationTol=0.1) {

class LeadTimeColumn

As of 16.5, a new interface for lead time has been added to core Part. As a result, a new lead time column has been created in cm/core/init/leadTimeColumn.cm. Extensions who have their own Lead Time column should migrate to the core version to avoid duplication.

Developers can migrate by:

• Preferred option:
  • If applicable, remove registry of a custom Lead Time Column
  • Implement leadTime() in Part to get accurate value for core Lead Time column
• Secondary option:
  • If custom lead time column exists...
    • Remove registry of a custom Lead Time Column
    • Utilize overridePartColumns() on Part to return custom lead time column in place of core column

/**
 * Lead Time Column for Parts
 */
public class LeadTimeColumn extends BasicPartColumn {

    /**
     * Constructor.
     */
    public constructor() {
		super("coreLeadTime");
    }
    

    /**
     * Initial Visibility.
     */
    public symbol[] initialVisibility() {
		return [#none];
    }


    /**
     * Return property value for part.
     */
    public Object value(Part part, Space space) {
        return part.leadTime();
    }
}

hooks.cm

A new hooks.cm file has been added to the cm/core/itemTag package. The public functions below have been moved to it from the itemTag.cm file.

public bool updateWorldItemTags(World world, bool validate, PriceChangeEnv env) {}
public bool updateSpaceItemTags(Space space, bool validate, function():bool interrupt, bool force) {}
public void updateSpaceItemTags(Space space) {}

class ItemTagInfo

A new field str articleCodeText has been added in ItemTagInfo.

• Holds the article code value of the Part associated with the ItemTag
• Allows for the new control panel setting toggling article codes as Ind tags (only visually, not on export)
• New getTagText() function returns ItemTagInfo text based on setting
  • See runtime behavior documentation for ItemTagInfo

The fields value is set in core Part during updateItemTags() or it can be set on construction with this new constructor:

/**
 * Creates a new ItemTagInfo.
 */
public constructor(str text, str k, str textType, str articleCode) {
	articleCodeText = articleCode;
	this(text, k, textType);
}

The new getTagText() function checks the setting value to return either the articleCodeText or the tagText:

/**
 * Get tag text.
 */
extend public str getTagText() {
	if (displayArticleCodeForItemTag) return articleCodeText;
	return tagText;
}

functions.cm

A new functions.cm file has been added to the cm/core/itemTag package. The public functions below have been moved to it from the itemTag.cm file.

public void enableItemTagsAlwaysUpdate(bool on) {}
public bool itemTagsAlwaysUpdateEnabled() {}
public void removeItemTags(Snapper this) {}

class PartProxy

The following functions were added to PartProxy in v16.5. These functions were added in support of the new pricing model which is documented in the compile-time section for cm.core.part.Part.

New: extend public double basePrice(Part part, bool includeChildren=false, Space space=null, bool translatePrice=true) {}
New: extend public double optionPriceSum(Part part, bool includeChildren=false, Space space=null, bool translatePrice=true, bool invalidate=false) {}

class Part

Constructor Migration: List Price → Base Price + Option Price Sum

In v16.5, a new constructor has been introduced for Part to support the new pricing model. Previously, Part accepted a cached list price (listPrice) directly as a parameter. This behavior is now being phased out.

Old Constructor

• constructor(Snapper snapper, str articleCode, str description, double listPrice, ...)
• Relies on cached listPrice.
• Marks Part with data._useNewPricing = false to use old pricing behavior.

New Constructor (preferred, introduced in 16.5)

• constructor(Snapper snapper, str articleCode, str description, double basePrice, Double optionPriceSum, ...)
• Accepts basePrice and optionPriceSum separately.
• Marks Part with data._useNewPricing = true to activate new pricing behavior.
• Double optionPriceSum Parameter
  • Nullable
  • If a value is provided → it is treated as the cached option price sum.
  • If null is provided → the option price sum will be generated on demand when required.
    • Recommended approach for most use cases.
    • See new pricing API section for generateOptionPriceSum() documentation
  • NOTE: cached option price sum value is removed in invalidateOptionPriceSum

Impact

• Migrate to new constructor and split your values into basePrice and optionPriceSum.
• All new core features and pricing rules will rely on the new constructor/pricing system.
• The old constructor remains for backward compatibility

Example Old and New Constructor Usage

Old: new Part(snapper, "PART NUM", "PART DESC", listPrice=199.99);
New: new Part(snapper, "PART NUM", "PART DESC", basePrice=150, optionPriceSum=49.99);
New: new Part(snapper, "PART NUM", "PART DESC", basePrice=150, optionPriceSum=null);

Old Pricing API

The following functions are now part of the old pricing system. The new pricing API is introduced in v16.5 and documented in the next section. The old API will remain for backwards compatibility but is expected to be removed in a future version of CET.

extend public double customListPrice()
extend public Double upcharge()

extend public double customListPrice()

Old → New behavior

Old:

• if applicable, returns PartProxy list price value
• returns PartData cached list price value
• overridable interface to customize list price value

New:

• Same behavior within method.

Impact

• Migrate to new pricing API and plan to remove all reliance on customListPrice()
• See listPrice() and calculatedListPrice(..) documentation for more migration information

extend public Double upcharge()

Old → New behavior

Old:

• upcharge() returns null.

New:

• Replaced by optionPriceSum().
• Still supported if useNewPricing() == false.

Impact

• Migrate to new pricing API and plan to remove all reliance on upcharge()
• See optionPriceSum(..) and calculatedListPrice(..) documentation for more migration information

New Pricing API (v16.5 and later)

The following functions were introduced as part of the new pricing system. They replace Old pricing methods that relied on a cached list price.

Added: final public bool useNewPricing() {}
Added: extend public double basePrice(bool includeChildren=false, Space space=null, bool translatePrice=true) {}
Added: extend public double optionPriceSum(bool includeChildren=false, Space space=null, bool translatePrice=true, bool invalidate=false) {}
Added: final public double calculatedListPrice(bool includeChildren=false, Space space=null) {}
Added: extend public Double generateOptionPriceSum() {}
Added: extend public void invalidateOptionPriceSum() {}

Added: extend public bool useNewPartPricing() {}

Indicates whether the new part pricing system should be used on the Part instance. An opt-in feature flag to the new pricing system.

Behavior

• Returns cached value from PartData
• Value is set during construction:
  • Using new constructor sets this value to true
  • Using old constructor sets this value to false

Impact

• Acts as the feature flag for determining which pricing path is followed in constructors, listPrice, upcharge, basePrice, optionPriceSum, etc.
• Developers should begin migrating logic to use base price + option price sum rather than raw list price.

Added: extend public double basePrice(bool includeChildren=false, Space space=null, bool translatePrice=true) {}

Parameters

• bool includeChildren (optional)
  • default false
  • if true, recursively adds child part base prices to returned value
• Space space (optional)
  • default null
  • utitlized for calling translatePrice
• bool translatePrice (optional)
  • default true
  • if true, translates price value to current currency for space

Old → New behavior

Old:

• basePrice() is implemented in cm.abstract.part.AbsPart
  • returns list price by default
  • does not utilize cached base price
  • does not utilize PartProxy
  • does not implement the core specials system
  • overridden in DsPart to return catalog base price

New:

• basePrice() is implemented in cm.core.part.Part
  • if applicable, returns special amount if a PartSpecial is found
  • if applicable, returns PartProxy base price value
  • returns PartData cached base price
  • Supports:
    • Including child part base prices.
    • Optional currency translation via space.
    • Accounting for specials (PartSpecial).

Impact

• Utilize the new constructor to set the cached basePrice for the Part
• Replace usage of raw listPrice with basePrice where you need only the product’s inherent cost

Added: extend public double optionPriceSum(..)

Parameters

• bool includeChildren (optional)
  • default false
  • if true, recursively adds child part option price sums to returned value
• Space space (optional)
  • default null
  • utitlized for calling translatePrice
• bool translatePrice (optional)
  • default true
  • if true, translates price value to current currency for space
• bool invalidate (optional)
  • defaults false
  • if true, invalidates cached option price sum value, triggering regeneration

Old → New behavior

Old:

• upcharge() is implemented in cm.abstract.part.AbsPart
  • returns null by default
  • does not utilize cached value
  • does not utilize PartProxy
  • does not utilize core specials system

New:

• optionPriceSum() is implemented in cm.core.part.Part
  • if useNewPricing is false, returns upcharge()
  • if applicable, returns PartProxy option price sum value
  • returns PartData cached option price sum
    • if cached value is null (or invalidate=true), value is regenerated automatically with generateOptionPriceSum()
  • Supports:
    • Including child part option price sums.
    • Optional currency translation via space.
    • Accounting for specials (PartSpecial)

Impact

• Replace calls to upcharge() with optionPriceSum()
• If your code updates Part options dynamically, call invalidateOptionPriceSum() before recalculation.

Added: final public double calculatedListPrice(..)

Parameters

• bool includeChildren (optional)
  • default false
  • if true, recursively adds child part list prices to returned value
• Space space (optional)
  • default null
  • utilized for calling translatePrice
• bool translatePrice (optional)
  • default true
  • if true, translates price value to current currency for space
• bool invalidateOptionPriceSum (optional)
  • default false
  • if true, invalidates option price sum value for regeneration

Old → New behavior

Old:

• customListPrice(..) is primary source of list price value
  • if applicable, returns PartProxy list price value
  • returns PartData cached list price value
  • overridable interface to customize list price value
  • Used by listPrice() when useNewPricing == false

New:

• calculatedListPrice(..) is primary source of list price in new pricing model
  • no longer relies on a cached list price value
  • returns calculated list price value (basePrice(..) + optionPriceSum(..))
  • not an overridable interface
  • Used by listPrice() when useNewPricing == true

Impact

• If your system overrides customListPrice(..) to customize list price, migrate this logic into:
  • basePrice(..) (for foundational Part price)
  • and/or optionPriceSum(..)/generateOptionPriceSum() (for option pricing logic).
• listPrice() will automatically call calculatedListPrice(..) if useNewPricing is enabled.

Added: extend public Double generateOptionPriceSum()

Old → New behavior

Old:

• Not applicable.

New:

• Returns the newly generated option price total.
• Default implementation returns null.
• Extended Part classes should override this method to compute option pricing correctly for their system.
  • Overridden in ProdPart and DsPart

Impact

• If you have custom option price logic, override generateOptionPriceSum() in your extended Part class.
• Invalidate the cache (invalidateOptionPriceSum()) when option state changes to trigger regeneration.

Added: extend public void invalidateOptionPriceSum()

Old → New behavior

Old:

• Not applicable.

New:

• Invalidates cached optionPriceSum value to trigger regeneration
• Call invalidateOptionPriceSum() whenever Part configuration changes (options, children, etc.)

Impact

• Add invalidateOptionPriceSum() after any Part modifications that may affect option pricing.

New Part API

The following functions were added or changed in Part in v16.5. The new pricing model API is documented above and not included in this section.

translatePrice functions were modified to remove unused includeChildren parameter.

Added: extend public double totalBasePrice(bool includeChildren=false, Space space=null) {}
Added: extend public double totalOptionPriceSum(bool includeChildren=false, Space space=null) {}

Old: final public double translatePrice(double price, bool includeChildren=false, Space space=null) {
New: final public double translatePrice(double price, Space space=null) {

Old: final public double translatePrice(double price, currencyId currency, bool includeChildren=false, Space space=null) {
New: final public double translatePrice(double price, currencyId currency, Space space=null) {

New Lead Time Interface

As of 16.5, a new interface for lead time has been added to core Part. It's value is displayed in the new LeadTimeColumn implemented in cm/core/init/leadTimeColumn.cm.

In cm/core/part/part.cm

/**
 * Get lead time string.
 * Ex. 20 days, 3 weeks, etc.
 */
extend public str leadTime() {
	return "";
}

class WorldPart

Constructor Migration: List Price → Base Price + Option Price Sum

In v16.5, a new constructor has been introduced for WorldPart to support the new pricing model. Previously, WorldPart accepted a cached list price (listPrice) directly as a parameter. This behavior is now being phased out.

Old Constructor

• constructor(World world, str articleCode, str description, double listPrice, ...)
• Accepts a total listPrice value to cache.
• See documentation in compile-time section for cm.core.part.Part for more info

New Constructor (preferred, introduced in 16.5)

• constructor(World world, str articleCode, str description, double basePrice, Double optionPriceSum, ...)
• Accepts basePrice and optionPriceSum separately for caching.
• See documentation in compile-time section for cm.core.part.Part for more info

Impact

• Migrate to new constructor and split your values into basePrice and optionPriceSum.
• All new core features and pricing rules will rely on the new constructor/pricing system.
• The old constructor remains for backward compatibility

Example Old and New Constructor Usage

Old: new WorldPart(snapper, "PART NUM", "PART DESC", listPrice=199.99);
New: new WorldPart(snapper, "PART NUM", "PART DESC", basePrice=150, optionPriceSum=49.99);
New: new WorldPart(snapper, "PART NUM", "PART DESC", basePrice=150, optionPriceSum=null);

class PartSpecialHolder

Added: public str[] specialKeys();

• Stores an ordered sequence of special keys
• Allows for tracking of order of insertion of added custom specials

Behavior

• Appended to during put
• Removed from during remove
• Cleared during removeAll

class PartAnnotationHolder

See cm.core.part.attributes section in 16.5 New Features migration guide for new PartAnnotationHolder class documentation.

class PartData

New Interface

The following functions were added to PartData in v16.5. These functions were added in support of the new pricing model which is documented in the compile-time section for cm.core.part.Part.

// FUNCTIONS
New: extend public bool useNewPricing() {}
New: extend public double basePrice() : abstract {}
New: extend public void setBasePrice(double v) : abstract {}
New: extend public Double optionPriceSum() : abstract {}
New: extend public void setOptionPriceSum(Double v) : abstract {}

class PartAnnotation

See cm.core.part.attributes section in 16.5 New Features migration guide for new PartAnnotation class documentation.

class BasicPartData

Constructor Migration: List Price → Base Price + Option Price Sum

In v16.5, a new constructor has been introduced for BasicPartData to support the new pricing model. Previously, BasicPartData accepted a cached list price (listPrice) directly as a parameter. This behavior is now being phased out.

Old Constructor

• constructor(Snapper snapper, str articleCode, str description, double inPrice=0, double outPrice=0, ...)
• Accepts a total outPrice (list price) value to cache.
• Marks _useNewPricing as false to use old pricing behavior.

New Constructor (preferred, introduced in 16.5)

• constructor(Snapper snapper, str articleCode, str description, double basePrice=0, Double optionPriceSum=null, ...)
• Accepts basePrice and optionPriceSum separately for caching.
• Marks _useNewPricing as true to activate new pricing behavior.
• Sets _outPrice field to (basePrice + optionPriceSum)
  • This field is unused in the new pricing model
• Double optionPriceSum Parameter
  • See new pricing API section in cm.core.part.Part for documentation

Impact

• Migrate to new constructor and split your values into basePrice and optionPriceSum.
• All new core features and pricing rules will rely on the new constructor/pricing system.
• The old constructor remains for backward compatibility

Example Old and New Constructor Usage

Old: new BasicPartData(snapper, "PART NUM", "PART DESC", outPrice=199.99);
New: new BasicPartData(snapper, "PART NUM", "PART DESC", basePrice=150, optionPriceSum=49.99);
New: new BasicPartData(snapper, "PART NUM", "PART DESC", basePrice=150, optionPriceSum=null);

New BasicPartData Interface

The following functions and fields were added to BasicPartData in v16.5. These functions were added in support of the new pricing model which is documented in the compile-time section for cm.core.part.Part.

// FIELDS
New: package bool _useNewPricing;
New: public double _basePrice;
New: public Double _optionPriceSum;

// OVERRIDDEN FUNCTIONS (from PartData)
New: public bool useNewPricing() {}
New: public double basePrice() {}
New: public void setBasePrice(double v) {}
New: public Double optionPriceSum() {}
New: public void setOptionPriceSum(Double v) {}

class PartMakeSpecialDialog

Constructor change

The PartMakeSpecialDialog constructor has been changed to accept a new parameter label. The new parameter allows for customization of the dialogs label but the label is still defaulted to the title "Make/Change Special".

Old: public constructor(Window parent, PartSpecial original) {}
New: public constructor(Window parent, PartSpecial original, str label=$specialsDialog) {}

Added: extend public PartSpecial generateSpecial() {}

The helper method generateSpecial() has been introduced to streamline the process of creating PartSpecial objects from dialog input.

• Encapsulates the logic for constructing a PartSpecial from dialog contents.
• Uses current values from UI fields to populate the new object:

return PartSpecial(partNumTF.text,
                   descrTF.text,
                   priceReplaceRB.currentState > 0,
                   amountDF.value);

Added: extend public PartSpecial generateCustomSpecial(PartSpecial original) {}

The helper method generateCustomSpecial() has been introduced to streamline the process of creating custom PartSpecial objects from dialog input.

• Currently returns null but provides a clear hook for future overrides.

In 16.5, the QueryDialogDataEnv has changed it's backing data structures, replacing the str->Part parts and int->str rowIDs maps with a single QueryRowData[] queryRows data sequence. Cell highlighting has also been introduced in the QueryDialog.

As a result, the following functions have been removed and added to QueryPartGridBuilderEnv.

Removed: public str rowIdentifier(Object data) {}
Added: public GridCell[] getRowCells(Object data) {}
Added: public Brush getCellBrush(Object data, int columnIdx) {}

class QueryDialogDataEnv

In 16.5, The QueryDialogDataEnv has changed it's backing data structures, replacing the str->Part parts and int->str rowIDs maps with a single QueryRowData[] queryRows data sequence.

Old vs. New Behavior

Old:

• Relied on maps for matching grid row ids to Part instances
  • str->Part parts
  • int->str rowIDs
• Challenges:
  • Heavily relied on keys and ID management for aligning UI with data
  • Prone to issues with duplicated keys/IDs which led to more complex handling
  • Introduction of custom specials unraveled this structure

New:

• New atomic data structure to represent single rows in the grid (QueryRowData)
• New single sequence in data env to hold rows (QueryRowData[] queryRows)
• Improvements:
  • Direct access to row data using int indexes rather than str keys/ids
  • Single data structure to connect UI and data values
  • Ordered data sequence directly represents grid rows

As a result of this change, the following functions and fields were modified in the QueryDialogDataEnv interface.

// Modified data fields
Old: public str->Part parts;
Old: public int->str rowIDs;
New: public QueryRowData[] queryRows;

// Modified data field accessors/manipulation
Old: extend public Part[] setParts(Part[] value) {}
Old: extend public int->str setRowIDs(int->str value) {}
Old: extend public void buildParts() {}
New: extend public void buildQueryRowData(Part[] parts=null) {}

// Modified to new data structure (str id -> int row)
Old: extend public PartSpecial getSpecial(str id) {} 
New: extend public PartSpecial getSpecial(int row) {}

Old: extend public void putSpecial(str id, PartSpecial special) {}
New: extend public void putSpecial(int row, PartSpecial special) {}

Old: extend public void removeSpecial(str id) {}
New: extend public void removeSpecial(int row) {}

// Added helper functions
New: extend public void refreshQueryRowData() {}
New: extend public QueryRowData createPartRowData(Part part) {}
New: extend public bool contains(PropObj propObj) {}
New: extend public bool any() {}
New: extend public bool empty() {}
New: extend public QueryRowData getRowData(int row) {}

NOTE: Things labelled as Old were removed interface and those labeled as New were added. The Old/New labels are utilized to clearly demonstrate the migration of changes.

In 16.5, the QueryDialogDataEnv has changed it's backing data structures, replacing the str->Part parts and int->str rowIDs maps with a single QueryRowData[] queryRows data sequence.

As a result, the extended type QueryPartRowData has been created to represent a core Part query dialog row.

class QueryDialogBehavior

Data Backend Changes

In 16.5, The QueryDialogDataEnv has changed it's backing data structures, replacing the str->Part parts and int->str rowIDs maps with a single QueryRowData[] queryRows data sequence. View more documentation about this change in the section for cm.core.part.query.QueryDialogDataEnv.

The following functions in the QueryDialogBehavior have been updated to reflect the new index-based data retrieval versus the old key/id based retrieval. They perform the same purposes with the only notable change being in buildGridWindow which is documented further below.

Old: extend public int->str buildGridWindow(GridWindow grid, Part[] parts) {}
New: extend public void buildGridWindow(GridWindow grid, Object rows) {}

Old: extend public PartSpecial getSpecial(QueryDialog dialog, str id) {}
New: extend public PartSpecial getSpecial(QueryDialog dialog, int row) {}

Old: extend public void putSpecial(QueryDialog dialog, str id, PartSpecial special) {}
New: extend public void putSpecial(QueryDialog dialog, int row, PartSpecial special) {}

Old: extend public void removeSpecial(QueryDialog dialog, str id) {}
New: extend public void removeSpecial(QueryDialog dialog, int row) {}

Old: extend public GridCell[] getRowCells(QueryDialog dialog, str id) {}
New: extend public GridCell[] getRowCells(QueryDialog dialog, int row) {}

Old: extend public GridCell getCell(QueryDialog dialog, str columnLabel, str rowID) {}
New: extend public GridCell getCell(QueryDialog dialog, str columnLabel, int row) {}

Old: extend public DialogWindow getSpecialDialog(QueryDialog dialog, str id) {}
New: extend public DialogWindow getSpecialDialog(QueryDialog dialog, int row) {}

Changed: extend public int->str buildGridWindow(GridWindow grid, Part[] parts) {}

The buildGridWindow function no longer takes in a Part sequence as a parameter and no longer returns an int->str row-index to row-id map. It now accepts a generic Object type for its row building. It's return type has changed to void with the reverted need for row IDs.

Old vs. New Behavior

Old:

• Accepted Part[] parts as a parameter
• Built rows directly from Parts sequence
• Returned int->str map of row-indexes to row-ids for caching on QueryDialogDataEnv

New:

• Accepts an Object type for a row data parameter
• Builds rows using GridBuilders generic populateGridWindow function which takes in an Object
• Returns nothing anymore as row-ids are no longer cached on QueryDialogDataEnv

Impact

• Developers wanting to manage their grid building should override GridBuilder and it's populateGridWindow interface
  • Supply the customized builder to the QueryDialogBehavior on your PropObj

Other QueryDialogBehavior Changes

The following functions have been modified, added to, or removed from QueryDialogBehavior in v16.5.

Added: extend public QueryRowData[] getQueryRows(QueryDialog dialog) {}

• See documentation in the above "New Data Backend" section and/or the compile-time section for cm.core.part.query.QueryDialogDataEnv for more info.

class QueryRowData

In 16.5, the QueryDialogDataEnv has changed it's backing data structures, replacing the str->Part parts and int->str rowIDs maps with a single QueryRowData[] queryRows data sequence. As a result, the abstract class QueryRowData has been created to represent a generic query dialog row.

• Carryies current instance of a row's data (Part, SpecOption, etc)
• Manipulates specials for the row's data type

Interface

/**
 * QueryRowData
 * 
 * This abstract class is responsible for managing 
 * data for a row in a QueryDialog.
 */
public class QueryRowData : abstract {

    /**
     * ID for this row data instance.
     */
    public str id;
    
    /**
     * The data object associated with this row.
     */
    public Object data : copy=reference;

    
    /**

class QueryDialog

Data Backend Changes

In 16.5, The QueryDialogDataEnv has changed it's backing data structures, replacing the str->Part parts and int->str rowIDs maps with a single QueryRowData[] queryRows data sequence. View more documentation about this change in the section for cm.core.part.query.QueryDialogDataEnv.

The following functions in the QueryDialog have been updated, added, or removed to reflect the new index-based data retrieval versus the old key/id based retrieval.

Old: extend public str selectedRowID() {}
New: extend public int selectedRow() {}

Old: extend public PartSpecial getSpecial(str id) {}
New: extend public PartSpecial getSpecial(int row) {}

Old: extend public void putSpecial(str id, PartSpecial special) {}
New: extend public void putSpecial(int row, PartSpecial special) {}

Old: extend public void removeSpecial(str id) {}
New: extend public void removeSpecial(int row) {}

Removed: extend public str->Part parts() {}
Removed: extend public int->str rowIDs() {}
Added: extend public QueryRowData selectedRowData() {}

Other QueryDialog Changes

The following functions have been added and removed from QueryDialog in v16.5.

Added: extend public bool any() {}
Added: extend public bool empty() {}
Added: extend public bool contains(PropObj propObj) {}
Added: public bool keyCode(Window originator, KeyCode keyCode) {}

Removed: extend public bool containsSpecial() {}

Added: extend public bool any() {}

• Checks if the QueryDialog contains any backing data
• A quick way to see if the QueryDialog has any data

Behavior

• Calls any() on the dialogs QueryDialogDataEnv env
• Returns true if data contains any QueryDataRows; false if not

Added: extend public bool empty() {}

• Checks if the QueryDialog contains any backing data
• A quick way to see if the QueryDialog has no data

Behavior

• Calls empty() on the dialogs QueryDialogDataEnv env
• Returns false if data contains any QueryDataRows; false if not

Added: extend public bool contains(PropObj propObj) {}

• Checks if the QueryDialog contains the passed in propObj in it's backing data

Behavior

• Calls contains(..) on the dialogs QueryDialogDataEnv env
• See documentation in the compile-time section for cm.core.part.query.QueryDialogDataEnv for more info

Added: public bool keyCode(Window originator, KeyCode keyCode) {}

• A new override of keyCode was added in QueryDialog to intercept Ctrl+A events originating from a QueryDialog.
• Previously, Ctrl+A would bubble up to CoreAppWindow and trigger a selectAll action on snapper elements, which was not desirable.

Behavior

• Intercepts the Ctrl+A key combination.
  • If the event originates from a GridWindow, it returns true immediately to prevent parent handling
  • Otherwise, the event is forwarded to the query dialogs GridWindow via gridWindow().?key(CTRL_A)
• All other key events are passed to the superclass via super(..)

initFromPropsScheme cleanup

The following interfaces have been consolidated, there should be no necessary changes.

Old: public void initFromPropsScheme(PropObj obj) : deprecated {
New: public void initFromPropsScheme(PropObj obj, str systemKey=null, World world=null) {

PropsSchemeQPInfo cleanup

We have made str systemKey an optional argument and removed the World w=null argument.

Old: public PropsSchemeSpecificQPInfo propsSchemeQPInfo(CoreObject obj, World w=null) {
Old: public PropsSchemeSpecificQPInfo propsSchemeQPInfo(CoreObject obj, str systemKey, World w=null) {
New: public PropsSchemeSpecificQPInfo propsSchemeQPInfo(CoreObject obj, str systemKey=null) {

PropsSchemeFilterButton

Following the interface change introduced for BrushHoverButton, the constructor for PropsSchemeFilterButton has been updated.

Old: public constructor(Window parent,
                        Brush stdBrush,

                        SrcRef src=#:src) {

PropsSchemeDialog

We have optimized props scheme dialog by eliminating unnecessary nested SubWindow in cards, schemeBarSub, barsAndOptions, and applyWins. The following methods have been removed as they are now unnecessary:

Removed: extend public void layoutApply(Window reference=null) {}
Removed: extend public void layoutSelection() {}

Previously, these methods were used to adjust margins caused by the presence of the now-removed applyWindow sub-window.

psCardWindow

The following methods have been removed as redundant window resizing operations are no longer required in these methods:

Removed: public void ancestorResizeEnd() {}
Removed: public void parentClientBoundChanged() {}

They will now inherit the behaviours from Card instead.

SelectionFloatingDialog

A small addition of a default argument str loc=callerLoc() to the constructor.

Old: public constructor(Window parent,
                        Font font=systemFont(),
                        Brush brush=null,
                        str label="Dialog",
                        bool initVisible=true,
                        bool noBorder=false) : deprecated {
New: public constructor(Window parent,
                        Font font=systemFont(),
                        Brush brush=null,
                        str label="Dialog",
                        bool initVisible=true,
                        bool noBorder=false,
                        str loc=callerLoc()) { // Added

TBInfo changes

The class field lastSelectedTab has been removed and is replaced with lastSelectedTabKey. The decision to store the last selected tab's key instead of the index position is to allow exact string matching when remembering and restoring the last selected toolbox tab, further improving consistency when loading the last selected toolbox tab.

Removed: public int lastSelectedTab;
Added: public str lastSelectedTabKey;

MessageWindow

The MessageWindow class has been moved from cm.core.toolbox to cm.win.

Toolbox

The cm.win function endProgress was accidentally overriden by Toolbox in 16.0, this has been removed.

Removed:  final public void endProgress() {

ToolboxButtonPainter

New argument UIHint hint has been added.

Old: public constructor(ComboTextPainter victim, str->Object styles) : deprecated {
New: public constructor(ComboTextPainter victim, str->Object styles, UIHint hint) {

LazySnapper3DMemoryButton

The method convertToBitmap has been removed as it is no longer necessary to convert a DibImage into a MemoryImage.

Removed: extend public void convertToBitmap(DibImage dib, sizeI dim) {

class UserPart

Constructor Migration: List Price → Base Price + Option Price Sum

In v16.5, a new constructor has been introduced for UserPart to support the new pricing model. Previously, UserPart accepted a cached list price (listPrice) directly as a parameter. This behavior is now being phased out.

Old Constructor

• constructor(World world, ..., double listPrice, ...)
• Accepts a total listPrice value to cache.
• See documentation in compile-time section for cm.core.part.Part for more info

New Constructor (preferred, introduced in 16.5)

• constructor(World world, ..., double basePrice, Double optionPriceSum, ...)
• Accepts basePrice and optionPriceSum separately for caching.
• See documentation in compile-time section for cm.core.part.Part for more info

Impact

• Migrate to new constructor and split your values into basePrice and optionPriceSum.
• All new core features and pricing rules will rely on the new constructor/pricing system.
• The old constructor remains for backward compatibility

Remove: public class PrevCatChecked {

Old: public class CategoryUndoOp {
New: package class CategoryUndoOp {
Old: public class AddCategoryUndoOp {
New: package class AddCategoryUndoOp {
Old: public class RemoveCategoryUndoOp {

Old: public constructor(symbol cat, Snapper{} snappers, PrevCatChecked{} theDescendants = null) {
New: public constructor(symbol cat, Snapper{} snappers) {

gMaterial3DLegacy.cm

MemoryImage to be casted to DibImage and destroyed explicitly to reduce GDI Object usage.

Old: public MemoryImage loadOldGMaterial3DThumbnail(Url url, gmThumbnailType thumbnailType=gmThumbnailType.flat) {
New: public DibImage loadOldGMaterial3DThumbnail(Url url, gmThumbnailType thumbnailType=gmThumbnailType.flat) {

gMaterial3DHelpers.cm

Since getThumbnail(memoryStream) return a DibImage now, return it as a DibImage in loadDexGMThumbnail().

Old: public Image loadDexGMThumbnail(Url url, gmThumbnailType thumbnailType=gmThumbnailType.flat) {
New: public DibImage loadDexGMThumbnail(Url url, gmThumbnailType thumbnailType=gmThumbnailType.flat) {

Match loadOldGMaterial3DThumbnail() and loadDexGMThumbnail() change to return DibImage.

Old: public Image loadGMaterial3DThumbnail(Url url, gmThumbnailType thumbnailType=gmThumbnailType.flat) {
New: public DibImage loadGMaterial3DThumbnail(Url url, gmThumbnailType thumbnailType=gmThumbnailType.flat) {

Text3D changes

The following new fields fontWeight wght, bool italic, and bool underline have been added. As such, a constructor has been updated to set these fields.

public class Text3D extends Primitive3D {
    Old: public constructor(str text, float height, float thickness, str fontFace, LayerExpr layer=null) {
    New: public constructor(str text, float height, float thickness, str fontFace, fontWeight wght=fontWeight.normal, bool italic=false, bool underline=false, LayerExpr layer=null) {
}

load.cm

Removed redundant loadDwg function

Removed: public DwgRoot loadDwg(Url path, DwgImportEnv importEnv=null, bool verbose=false)

# CBBClient
Changed:
- final public void showLoginFailNotification() 
+ final public void showLoginFailNotification(rtoutcome reason, str errorType) 

Draw3DMeasureBase changes

The public field color currentFontColor has been removed and a new private field UserTextStyle _tStyle has been added. The old currentFontColor data is now stored inside the new field _tStyle. New methods color currentFontColor() and color currentFontColor=(color c) have been added so the interface of setting currentFontColor remains the same. By default, _tStyle will follow the style of Dimension text under the tools tab. However for existing 3D dimension from old drawing, user will still be seeing the previous style which always Arial with 50mm font height.

public class Draw3DMeasureBase extends DrawSnapper : abstract {
    Removed: public color currentFontColor;
    New: private UserTextStyle _tStyle;

New:
    /**
     * Current font color (get).

    extend public color currentFontColor() {
        if (tStyle) return tStyle.fontColor();
        return black;

            tStyle.setFontColor(c);
        }
        return currentFontColor();
    }
}
