What happens is when those controls redraw, some part of your view is invalidated, so you are asked to draw again. I suspect that when you draw, you are then using the rect parameter passed to -drawRect: to determine the extends of the gradient – which is incorrect. The rect parameter passed to -drawRect: is only a hint as to what parts of the view need to be redrawn. You should always do your drawing with respect to your view's bounds. -- David Duncan Apple DTS Animation and Printing _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
