Two things: 1) If you do not completely fill your view with drawing, you must override -isOpaque to return NO. 2) When -drawRect: is called, you are responsible for drawing anything and everything that should be drawn in that rectangle. You cannot make any assumptions that anything is left in there from a previous drawing operation. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
