Clearing a Rectangle

This topic shows you how to use CBitmapContext::Clear() to clear a rectangle to the current brush color.

      TRect largeBox(0,0,100,100);
TRect clearBox(20,20,40,40);
// draw a cross-hatched box
// clear a small rectangle
gc.SetBrushColor(KRgbGray); // change the brush color
gc.Clear(clearBox);   // clear to brush color

Note : When clearing a rectangle, the brush style is ignored, even if it is TBrushStyle::ENullBrush .
