Listen for bounds change notifications on the clip view (aka the scroll view's -contentView) instead. That's how scrolling actually works: the clip view changes its bounds origin and the regular view drawing machinery takes care of the rest by translating the document view's origin into the clip view's bounds coordinate system. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
