Difference when drawing with Brush Programming Software Development by pritaeas …the drawing of a custom bitmap brush, when I subclass TGraphicControl versus TCustomControl. The expected behaviour occurs when using the TCustomControl…Dialogs, Vcl.StdCtrls, Vcl.ExtCtrls, Vcl.Buttons; type TCard = class(TGraphicControl) // Change to TCustomControl to view the difference private FBackColor: TColor… Re: Difference when drawing with Brush Programming Software Development by pritaeas The only thing I can think of as to why this is happening, is that the custom control has it's own message loop (windows handle), whereas the graphic control does not. Still, any references to a definite answer are welcomed.
