NSStatusBarButton keep highlighted

Question

As of OS X 10.10 most of NSStatusItem has been deprecated in favour of the button property, which consists of an NSStatusBarButton. It should work like a norma

Answer 1

Here is one more option. Don't set NSStatusItem's action property. Instead add a local event monitor:

[NSEvent addLocalMonitorForEventsMatchingMask:(NSLeftMouseDown | NSRightMouseDown)
                                      handler:^NSEvent *(NSEvent *event) {
                                          if (event.window == self.statusItem.button.window) {
                                              [self itemClicked];
                                              return nil;
                                          }
                                          return event;
                                      }];

Then in -itemClicked highlight the button using highlight: method:

- (void)itemClicked {
    [self.statusItem.button highlight:YES];
    // Do other stuff 
}

To unhighlight just call button's highlight:NO where you need.
