Where would you put the selector for the Delete menu item, and how would you know when it gets called what collection view item to delete? By selector I assume you mean e.g. a -delete: IBAction method. That would go in the controller that is handling the view. To ensure it gets called, you simply ctrl-drag a connection from the menu item to the controller and choose this method. Verify it gets called using NSLog or the debugger. To actually implement the delete, you'd use the view's - selectionIndexes to find out what items to delete, remove them from your data model and call the view's -setContent: with the modified array from your model, and also remove the selection using - setSelectionIndexes: with an empty set. You might need to call - setNeedsdisplay:YES on the view to make it show the change. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Forgot to mention - if you are setting up the menu programmatically, you need to set the target of the menu item to the controller and the action method selector to the -delete: IBAction (it doesn't strictly need to be an IBAction in this case, but personally I find that declaring it as such is useful for managing the code and converting it to an IB-based solution later). If your menu is simple and not dynamic - i.e. it never changes according to the state of the item it's attached to - you might find it easier to set it up in IB rather than overriding -menuForEvent: - just create a menu object and connect it to the 'menu' outlet of the view. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
