Re: How to get a staticTextControl on a overlayWindow to show

Creating the control on such a window seems to be possible, based on noErr
results. But it won't show. Am I doing something impossible?

Overlay windows have a kEventWindowPaint handler installed by default, which clears the overlay window's context to transparent and returns noErr. Because the handler returns noErr, kEventWindowUpdate is never sent for overlay windows, and if you're looking for that event as a signal to call DrawControls (or if you have the standard window handler installed), you'll never get it.

You should be able to make this work by installing your own kEventWindowPaint handler, something like this:

case kEventWindowPaint:
if ( ( err = CallNextEventHandler( callRef, event ) ) == noErr )
DrawControls( window );
return err;
