I am trying to draw shape A and then erase or clear the shape and then when the mouse is clicked on top of shape A shape b will appear, I have used region, and when i press on shape A, shape B doesnt appear, but when i use the breakpoint the compiler is drawing shape B but then on the screen it doesnt appear.. If someone understands this and could give me some points about this.. i would be so gratefull! please help!
