It would be nice to have TControl.InvalidateRect, so that component
developers can avoid calls to LCLIntf.InvalidateRect :-)

Zeljan Rikalo <mailto:[email protected]> (developer) Not problem with
implementing that, but one can say we can implement almost all winapi
functions into TControl to avoid LCLIntf usage.
I'm not against adding InvalidateRect(R: TRect) into TControl, but
there must be
agreement from other devels about it
There is the question of drawing a lie, to how much to put on TWinControl.
There are more Handle related functions... So there could be an
additional HandleObject property, with an object representing the handle.
Though, IMHO that would be too much...
What is the specific use case for it?
I can only really see use, if you develop your own component. But then
you can add it there...
