V2.4

• BREAKING CHANGE: Renamed "TUICommandUpdateImageEvent" to "TUICommandUpdatePropertyEvent" and "TUICommand.OnUpdateImage" to "TUICommand.OnUpdateProperty". If assigned, "TUICommand.OnUpdateProperty" is now called in TUICommand.DoUpdate for any "TUIProperty"-parameter (not only images).
• Fixed issue #54: Add, Delete, Up and Down commands are enabled when no file is loaded.
• the code to detect the Delphi command line compiler now supports XE3 to 10.3.
• Fixed issue #65: Changing Scaling Policy size is not applied to the View Tree
• Fixed #64: Instead of defining own TUIPropertyKey use TPropertyKey from unit "WinApi.ActiveX".
• Ribbon elements with the exception of button are no longer shown disabled if no OnExecute event handler is assigned to their action.
• Removed call to "RefreshCommandCollection" during PropertyUpdated. Doing this here could cause a loop.
• Added another overload of TUICommand.Create, which can be used to create TUICommands at runtime more conveniently. As parameter, one can pass a TCustomAction. The action's image will be applied to the UICommand automatically.
• Fixed occasional AV that may occur during a call to RecreateWND. The AV would occur in UIRibbon.dll, after a call to FFramework.Destroy(). Setting the ref-counted member FFramework to nil in DestroyWND and re-instantiating it in CreateWnd solves the problem.
• Improved error handling in TUIRibbon.Load() for issue #62.
• Improved per-Monitor DPI awareness.
• Adjusted creation of TUIImage (from imagelist): Draw an empty background on the bitmap first, so that the transparency of the source image is preserved.
• Fixed AV that occurs when trying to run sample "03 DropDown Color Picker"
• Several improvemtns for TRibbonCollectionAction:
  • BREAKING CHANGE: TRibbonCollectionAction no longer stores a pair of TCustomAction and category string, but the Category property of the connected action is used.
  • Added another overload of TRibbonCollectionAction.Add() that allows to add simple "text only" items at runtime, that can be used in a combobox.
  • Added possibility to Remove existing actions from a TRibbonCollectionAction at runtime.
  • When adding new actions to a TRibbonCollectionAction, we skip invisible ones.
  • Implemented update-mechansim that removes actions from a TRibbonCollectionAction, as soon as they become invisible.
  • Added TRibbonCollectionAction.GetEnumerator, so that we can iterate it with for-each loops.
