The primary view is a custom view that displays objects spatially according to their position in x, y, z coordinate space. The secondary views are table type views. > If you're talking about a table/outline view, I'd just use the "selection did > change" delegate methods to propagate selections from one list to another. > > If not, but the selection is part of the state of a window controller, I'd > make a window controller property for each list, and observe those > properties, either in the window controller or the individual views. > > Or, if the selection is to be saved with the data model, I'd put a (probably > just one) selection set property in the data model, and use the window > controller (for example) as a mediating controller to propagate derived > properties to the views. I currently have a transient selection property for each object in the data model which helps in restoring the selection when undoing an object delete. The primary controller (for the custom primary view) is a custom programatic subclass of NSArrayController that synchronizes the primary controller selection with the transient selection property. The secondary controllers (NSArrayController and NSObjectController) and secondary views (table views) are all standard Interface Builder objects. The problem is how to synchronizing the selection among all the various controllers. --Richard Somers _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
