Thanks for your suggestions Ken, Indeed we do not ‘drawRect:’ anything in the scroll view. :-) >> (I have tried overriding prepareContentInRect: in the NSScrollView’s >> subclass, as well as in the view that serves as the scroll view’s document >> view.

Turns out the problem is a different, and of course, almost embarrassingly silly one. I misspelled the method name: prepareContentInrect rather than prepareContentInRect. Now that I’ve caught that and corrected it, the method is called. Thanks for you effort anyway. -António _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
