Well, I have quite a basic question which I can't seem to find an answer to. I followed this guide to create a StatusBar menu, which works great... However, I would like to add a custom NSMenuItem containing custom stuff. As example such as the sound slider, or the switch user account row ect.
How can I do that?
Even links to tutorials are welcome.
In most cases, you'll create a custom view containing the slider or whatever else you want to appear in the menu item. Then you call setView: on the NSMenuItem in question.
