Updates the window.

Declaration

- (void)update;

Discussion

The NSWindow implementation of this method does nothing more than post an NSWindowDidUpdateNotification notification to the default notification center. A subclass can override this method to perform specialized operations, but it should send an update message to super just before returning. For example, the NSMenu class implements this method to disable and enable menu commands.

An NSWindow object is automatically sent an update message on every pass through the event loop and before it’s displayed onscreen. You can manually cause an update message to be sent to all visible NSWindow objects through the NSApplication updateWindows method.
