The functions to create visually transparent windows (layered windows in Windows parlance) have been changed to make their purpose clearer: For more information, you can refer to the comments in cm/win/winApi.cm

Old: public void overlayCapture(mwnd hwnd, int alpha)
New: public void setLayeredWindow(mwnd hwnd, int alpha)

Old: public void setOverlayCaptureAlpha(mwnd hwnd, int alpha)
New: public void setLayeredWindow(mwnd hwnd, byte alpha)

Old: public void initOverlayCapture(mwnd hwnd, int alpha) = win_initOverlayCapture;
New: public void setLayeredWindow(mwnd hwnd, byte alpha) = win_setLayeredWindow;

New: public void removeLayeredWindow(mwnd hwnd) {}

The following methods on Window have been removed:

Removed: final public bool isSuspended() {}

The following method has been removed from FrameWindow:

Removed: final public void reportVisibleTime() {}

The Card constructor has been modified to remove the pos and size parameters:

New: public constructor(Pen pen, Pen highlightPen, bool onlyOnHover=false) {

A method was removed from the FaceliftToggle class:

Removed: extend public void drawToggle(PixelDevice device,
                                       pointI p,

                                       int innerOffset) : deprecated {}

The IconInfo class has been removed. As a result of this change, IconFinder's fields have been changed to remove references to this type:

Removed: public str->IconInfo icons();

The MenuBar class has a couple of its methods changed as follows:

Old: extend public int buildButton(str key,
                                   Image img,
                                   str toolTipText,

                                   int margin=0,
                                   bool right=false,
                                   bool assignIID=false) {}

New: extend public int buildButton(str key,
                                   Image img,
                                   str toolTipText,
                                   function(Control) cb,
                                   str bindingKey=null    // ADDED

New: final public void initIID(str buttonsIID, VisibilityProfile root)

The constructor for SeparatorLine has been changed to allow spawning it as a popup window:

Old: public constructor(Window parent,
                        FrameStyle frameStyle=thin3DFrame,
                        frame3DState frameState=frameStateDown,
                        int external=0,
                        int internal=0,
                        bool vertical=false,
                        bool light=false,
                        SrcRef src=#:src) {}

New:
Old: public constructor(Window parent,
                        FrameStyle frameStyle=thin3DFrame,
                        frame3DState frameState=frameStateDown,
                        int external=0,
                        int internal=0,
                        bool vertical=false,
                        bool light=false,
                        bool popup=false,    // ADDED
                        SrcRef src=#:src) {}

The following methods on TreeViewItem have been changed:

New: final public void sortByLabel(bool recursive=true, Object{} visited=null) {}

The following methods on TreeViewSubTree have been changed:

New: extend public void sortByLabel(bool recursive=true, Object{} visited=null) {}

The following functions have been removed from this package:

Removed: public bool removeRegisteredLanguage(str lang, str resKey, str nextLang) {}

GroupBox

Some changes have been made to GroupBox to rationalise it's behaviour regarding origins. The constructor now takes an origin offset instead of an origin directly:

Old: public constructor(Window parent,
                        Font font=systemFont(),
                        Brush brush=null,
                        FrameStyle frameStyle=noFrame,
                        frame3DState frameState=frameStateDown,
                        pointI origin=(0, 0),    // REMOVED
                        bool selectable=true,
                        pointI pos=(0, 0),
                        sizeI size=(0, 0),
                        bool passive=true,
                        str label=null,
                        color labelColor=color(),
                        str key=null,
                        SrcRef src=#:src) {}

New: public constructor(Window parent,
                        Font font=systemFont(),
                        Brush brush=null,
                        FrameStyle frameStyle=noFrame,
                        frame3DState frameState=frameStateDown,
                        pointI originOffset=(0, 0),    // ADDED
                        bool selectable=true,
                        pointI pos=(0, 0),
                        sizeI size=(0, 0),
                        bool passive=true,
                        str label=null,
                        color labelColor=color(),
                        str key=null,
                        SrcRef src=#:src) {}

The following method was also removed as part of this origin rationalisation:

Removed: final public void updateOrigin() {}

Previously, the API did not respect the origin set by the user, as an overriding origin was required to fit the text into the element. With the new originOffset parameter, a custom offset from the text of the GroupBox can now be specified.

The constructors for SubGroupBox and ShrinkBox have also been modified to match this change.

Added new argument to isValid method of G3StatsEntity in cm.win.eventLogG3.cm to allow for different validities for different event actions.

Old: extend public bool isValid()
New: extend public bool isValid(str action)

The following functions have been overritten in Display affecting displays with passive=true.

public void rightClick(pointI p) {
public void rightClick2(pointI p) {
public void rightRelease(pointI p) {
public void rightRelease2(pointI p) {

The setGlobalSkin(Skin) function is now a no-op when CET is in the new UI. This is part of larger plan to remove the Skin concept entirely in a future version of CET.
