What's the best way to update a non-modal dialog after changing one of
its dialog items?  Here's my problem: I want to display differing icons
in response to user radio button selections, right now I call DrawDialog(...)
to redraw the whole window but that causes everything to flicker and I would
rather just redraw the icon I have changed.  I tried just using InvalRect on
the rect returned by GetDItem but to no update event is generated...

Here's a synopsis of the code I have now:

	GetDItem(...);
	SetDItem(...);
	DrawDialog(...);

(BTW: I'm using MPW Pascal although I don't think it matters in this case)

Thanks for your help!

Dan
