Thanks, Todd, I'll give that a try. I don't have a problem understanding the concepts of constraints, at least at the most basic use (I definitely don't understand the priority system). But what flummoxes me is the way IB inserts constraints willy-nilly, and doesn't make it easy to set basic constraints. Not to mention that if you pin one edge of a view to its superview (for example), it then selects that new constraint, making it tedious to then pin the remaining three edges. It also doesn't do a good job of showing you what a particular constraint is really constraining (which views and attributes that are involved). -- Rick _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
