Instance Method


Called when the stack view is about to automatically detach one or more of its views.


optional func stackView(_ stackView: NSStackView, willDetach views: [NSView])



The stack view that is about to detach one or more of its views.


An array of one or more views, managed by the stack view, that are about to be automatically detached.


To configure a custom class to respond to the automatic detachment of views from a stack view’s view hierarchy, implement this method in the class. This method is not called when your code explicitly removes a view from a stack view’s views array.
