So no that's not really what the first responder is for. Why not subclassing that table view and overriding print:? This breaks the MVC paradigm. You'd have to forward print: to another view or better, forward it up to the controller and let the controller figure out what to do with it, although I think this kind of breaks the validateMenuItem interface. But you still have the problem that many different views can be first responder. You'd basically have to subclass every view that accepts first responder and override print: in each. It would also make code reuse much more cumbersome. All the views for one printing state would have to have a separate subclass from the views for the other printing state (this was my original issue, how do you manage printing when you have two main detail views that you swap between?). ->Ben -- Ben Lachman Acacia Tree Software http://acaciatreesoftware.com email: blach...@mac.com twitter: @benlachman mobile: 740.590.0009 ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
