sure, in wayland when creating a popup window is requested to provide a parent window.
When creating a window for a submenu, I had to find a way to retrieve the window of the parent menu, what the code does is:
1) get a NSWindow from windowid
2) get the NSMenu associated
3) get supermenu from the menu
4) get the window from the supermenu

to access the NSWindow [instance menu] I had to expose the attribute previously private. Here the change

Could you please explain this a bit? What is the issue here and what is your workaround? And what could be a better workaround in gui?
