Custom control clipping (irregular shape)

[ppyrstr]

I have been trying to figure out how to have a custom
control that is irregular (non-rectangular) not interfere
with other elements on the screen that may interfere with
it's "regular" shape (the control defining rectangle).
For example, if I make a custom control that simply paints
a circle inside its bounding box, how can I have the
control not have the area of the control outside of
the "bounding circle" affect any objects underneath it or
subsequently placed on top of these new "bounds." Any
suggestions would be welcome. Thanks.

Check out the Control.Region property.

Also, for very irregularly shaped regions, you might want to implement
something like this algorithm to generate your regions:

Hope that helps,
