This is current Idea for managing the connection to the interface and how it relates to handles


  • Fork a branch of lazarus/
  • Replace TWinControl.Handle with TWinControl.LCLHandle (there should exist no Handle yet)
  • Try to get the LCL compiled and maybe the IDE so it doesn't use the (inefficient) .Handle anymore
  • Introduce .Handle again, now as WSclass call
  • Merge the branches

TWSxxWinControl.CreateHandle Returns a TLCLHandle

ILCLHandle = IInterface;

TLCLHandle = ILCLHandle;

TxxPrivate = class(TPrivate, ILCLHandle);

TGtkPrivateButton = class(TGtkBin, TLCLHandle);

Other possibilities

{$IFDEF X11} TGtkPrivateWidget = class(TGtkPrivate, ILCLHandle, IX11);
