NSTreePopUpButton

The NSTreePopUpButton class adds supports for binding to a tree controller and displays the tree structure in a hierarchy of menus.

NSPopUpButton Binding

The NSPopUpButton can only display a one dimensional list of objects. The NSTreePopUpButton overwrites the binding to content and selectedIndex to work with a NSTreeController instance.

The content must be bound to arrangedObjects and selectedIndex to selectionIndexPath of a tree controller instance.

The NSTreePopUpButton creates nested menus to represent the object hierarchy. The state of every menu item in the selected index path is set to NSOnState.

Limitations

• The contentValues options is currently not supported. You should override the var description: String method in your class and return the value you want to display in the menu.
• The class does not support multiple selections.
