Re: drawing custom button in cocoa

If you want to limit the active area of your button the best way is
probably to override -hitTest:.

You should figure out if the point is in your active area (inside the
button shape) and return self if it is and return [super hitTest:event]
if it is not.

To do the test, you can do whatever is easiest.  One way would be to
create an NSBezierPath for the outline of the active area and use it to
hit test.
