I'm animating a Circle patch with a varying center and radius, and I
noticed that changing the ``radius`` attribute has no effect on the
patch. Currently, ``radius`` is only used to instantiate an Ellipse
object, but updating radius has no effect (i.e. redrawing the patch
doesn't use the new radius).
I've included a patch to add this feature. Also included in the patch
is a small fix to one of the UI examples (sorry for included a
completely unrelated patch but the fix seemed to small for a separate
email).
BTW, I'm using a property idiom from: http://code.activestate.com/recipes/205183/
. I thought that this approach was better than polluting the namespace
with getters and setters, especially since this would differ from the
way the Ellipse class uses ``width`` and ``height`` attributes.
Cheers,
-Tony
