Are you talking about selecting rows in a table view or an outline view, or selecting objects in a custom view? 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. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
