Renders the image of the form.

Pascal
procedure PaintWindow(DC: HDC); override;
C++
virtual __fastcall PaintWindow(HDC DC);
Description

Applications can't call this protected method. It is called when the form needs to be painted. 

PaintWindow locks the canvas to prevent threading issues, assigns the DC parameter as the Handle of the form's canvas, and then calls the Paint method to render the image of the form.
