Unlike its window counterpart (paintbox), a graphics box with pictures does not have its own window handle, and uses the parent window handle, like all other graphic visual elements. In particular, the graphic “artist's box” can no longer function as a regular panel and become a parent for other visual elements. Actually, there are no other differences, if we consider its basic functionality. The functionality of this element is all concentrated in the presence of the OnPaint event, and it works in much the same way as for the window twin.
