Revision as of 00:43, 4 April 2007 by AndrewH (talk | contribs) (Other possibilities)

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

Overview:

  • 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

TLCLHandle = IInterface;

TxxPrivate = class(TPrivate, TLCLHandle);

TGtkPrivateButton = class(TGtkBin, TLCLHandle);

Other possibilities

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

then

 (AWinControl as IX11).XID

is possible
