Instance Method

shouldCloseWindowController:delegate:shouldCloseSelector:contextInfo:

Determines whether the system should close the document and its associated window.

Declaration

- (void)shouldCloseWindowController:(NSWindowController *)windowController delegate:(id)delegate shouldCloseSelector:(SEL)shouldCloseSelector contextInfo:(void *)contextInfo;

Parameters

windowController

The window controller that is closed.

delegate

The delegate to which the selector message is sent.

shouldCloseSelector

The selector of the message sent to the delegate.

contextInfo

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

Discussion

If the window controller is the document's last one, or is marked as causing the document to close, this method calls the method in the shouldCloseSelector parameter with the result of canCloseDocumentWithDelegate:shouldCloseSelector:contextInfo:. In all other cases, this method calls shouldCloseSelector with YES. 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
