LCL Interface Redesign Idea

From Free Pascal wiki
Jump to navigationJump to search

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);
