Hello,

I want to make a button, that's not a square.
The only problem, however, is, that i want to be able to move over it, and so change the bitmap. But ONLY when you move over the 'not-overlay' part.

For example, a button that's a red circle.
When the mouse moves over it, it has to become yellow, but ONLY when it moves over the circle, NOT over the black (square) area around it.

How can i do this? (just set the overlay flag doesn't work)

Thanks,

Roy
