Instance Method

applicationShouldTerminateAfterLastWindowClosed:

Invoked when the user closes the last window the application has open.

Declaration

- (BOOL)applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)sender;

Parameters

theApplication

The application object whose last window was closed.

Return Value

NO if the application should not be terminated when its last window is closed; otherwise, YES to terminate the application.

Discussion

The application sends this message to your delegate when the application’s last window is closed. It sends this message regardless of whether there are still panels open. (A panel in this case is defined as being an instance of NSPanel or one of its subclasses.)

If your implementation returns NO, control returns to the main event loop and the application is not terminated. If you return YES, your delegate’s applicationShouldTerminate: method is subsequently invoked to confirm that the application should be terminated.
