Question

Is there a way to get the NSPanel a button is belonging to from the sender object ?

- (void)closeButtonClicked:(id)sender {
   ... something like [sender getPanel]...
}

Thanks

Answer 1

NSButton is an NSView subclass, NSView has a window property which gives access to the NSWindow it is in. If the button is in an NSPanel then its window property would contain that panel (NSPanel is a subclass of NSWindow). So something like

NSPanel* panel = (NSPanel*)[(NSButton*)sender window];

should get you the panel. I would check that they are of the right kind of class for safety.
