Dear All, I have a class A which inherit from Window class, I override it's draw function. And did nothing in this function.
Void A::draw() { return; } But I found that when I call show() or redraw() function, it can call draw function and refresh the window to black. Why? I think it should not refresh, because the draw has do nothing. Can anyone tell me what's the reason, and how to do nothing when call the draw() function. Thanks. _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
