I do this , but thats not work
If You have right, that what for is :
Procedure TWinControl.Repaint;
Begin
....
CNSendMessage(LM_PAINT, Self, nil); --> LCL send LM_Paint to interface,
^ this is empty call
....
end;
In windows if You call Invalidate after that must call WMPaint
and Repaint should do this,
I think that in Repaint is bug
PS. I know that Redraw is to CHILD, and I think Repaint is for whole object
REDRAW uses invalidate and update, REPAINT may use the same
