Are you sure you’re talking about ‘Containment’ segues here? Containment segues for me are the ones marked ‘Embed’ which go between Container Views and the thing they contain And those are editable and you can add identifiers to them and they trigger prepareForSegue in the NSViewController subclass at the front end. I just tested one. Are you talking in this case about the thing which looks like a segue and goes from the NSWindowController to the main NSViewController and is designated a ‘Relationship Segue’? Seems that’s also the type between NSSplitViewController and its splits? Indeed they appear to be uneditable and not like real segues at all despite being listed in the ‘Triggered Segues’ of the View Controller they come from. > > As far as I can tell: > > * They are “segues” only in the sense that they are lines drawn between > scenes in a storyboard.

That also begs the question as to why NSWindowController supports prepareForSegue since I can’t find a way to hook it up to anything except by a relationship segue which as you say appears not to actually be a segue. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
