Instance Method


Invokes shouldCloseSelector with the result of canClose(withDelegate:shouldClose:contextInfo:) if the specified window controller that is closing is the last one or is marked as causing the document to close.


func shouldCloseWindowController(_ windowController: NSWindowController, delegate: Any?, shouldClose shouldCloseSelector: Selector?, contextInfo: UnsafeMutableRawPointer?)



The window controller that is closed.


The delegate to which the selector message is sent.


The selector of the message sent to the delegate.


Object passed with the callback to provide any additional context information.


Otherwise it invokes shouldCloseSelector with true. This method is called automatically by NSWindow for any window that has a window controller and a document associated with it. NSWindow calls this method prior to sending its delegate the windowShouldClose(_:) message. Pass the contextInfo object with the callback.

The shouldCloseSelector callback method should have the following signature:

- (void)document:(NSDocument *)document shouldClose:(BOOL)shouldClose  contextInfo:(void  *)contextInfo
