Hi,
I have a window with backGroundcolor completely transparent.
[myWin setBackgroundColor:[NSColor colorWithDeviceRed:22. green:22.
blue:22. alpha:0]];
then I add to it a subView to draw something inside. (all this is
inspired by the overlay win apple example).
The view's drawRect routine simply draw a little centered rect with
the semi-transparent color:
[NSColor colorWithDeviceRed:22. green:22. blue:22. alpha:.3]
The problem is:
the centered rect doesn't remain transparent. Instead it becomes
completely in 2 or 3 redraws white!!.
Any idea
