Hi,

There are several calls to DefaultHandler in the LCL. Notably, TWinControl.PaintWindow, but there are more. Currently these do nothing. Shouldn't they be replaced with IntSendMessage or something alike? Or implement the DefaultHandler function? I guess that would call IntSendMessage after all, so we don't need the extra step.

Hmm.
The messages are a problem. They make it harder to create new interfaces, they are hardly extendable, they are not smart linkable and last but not least they make debugging more difficult. There are already far too many of them. I think, we should try to keep only the most common needed for delphi compatibility and replace the rest with methods.

Where is the difference to the VCL?

If these messages are annoying way of programming, which I think too, (large cases and such), why not remove them completely and replace with virtual functions all together? It'll make it a lot clearer and extendable, as you said.

Many Delphi components rely on them. IMO messages like WM_Paint, WM_Size, WM_Move should be kept. Messages like LM_Create, LM_SetPixel, LM_xx_xxx should be replaced.

Could you take (or have you taken) a ? The
code suggests that it's on it's 'way' to go send a message. It prepares message with type, wparam, lparam, etc. so that's why I suggested it.
