I'm looking to build a feature in my app to give user feedback if they have set their window to always show on top of other apps using a shortcut or application menu item, but find that there is a lot of hacking needed to do so. It may be more efficient to have an event listener set on the window to determine if it enters or leaves `win.setAlwaysOnTop()`

i'm thinking it would be `win.on('enter-always-on-top')` and `win.on('leave-always-on-top')` 
atom/browser/api/atom_api_top_level_window.h
v8::Local<v8::Value> val,
                     atom::NativeWindow** out) {
    
    if (val->IsNull()) {
      *out = NULL;
      return true;
    }
    atom::api::TopLevelWindow* window;
    if (!Converter<atom::api::TopLevelWindow*>::FromV8(isolate, val, &window))
      return false;
    *out = window->window();
    return true;
  }
};
}  
#endif
