You can't do this. Drawing outside of your view's bounds isn't supported. (More specifically, you must not draw outside of the rects returned by -getRectsBeingDrawn:count:). If your view ever becomes layer-backed (which is not a state you can entirely control), it won't necessarily be drawing to a backing store larger than its bounds. > A) What's the purpose of the wantsDefaultClipping method? As per the View Programming Guide[1], it exists to avoid duplicating any work you're already doing in order to restrict your drawing within the valid drawable regions.

Stop using -setFrame{,Origin,Size}: directly and start using auto layout. You can override -alignmentRectInsets to return the amount of padding on each side of your view, giving you enough room to draw your shadow. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
