TCustomForm.PaintWindow procedure
Calls the Paint method using the specified device context in the control Canvas.
Declaration
procedure PaintWindow(dc: Hdc); overrideArguments
dc | Device context (Handle) assigned to the Canvas for the form. |
Description
PaintWindow is an overridden method in
TCustomForm. It
re-implements the method from the ancestor class, and does
not call
the inherited method.
PaintWindow assigns the device context in dc to the
Canvas handle. The Paint method is called to signal the
OnPaint event handler (when assigned). If a design surface is
active for the form instance, its PaintGrid method is called. The
Canvas handle is reset to 0 prior to exiting from the method.
