If I call setIndentationLevel:
on an NSMenuItem then nothing happens, if I call indentationLevel
on it after I set it to 3, it returns 3 like it should. I'm adding the menu items to the Dock menu and I don't see anything changing.
NSMenuItem *menuItem = [[NSMenuItem alloc] initWithTitle: @"title" action: nil keyEquivalent: @""];
[menuItem setIndentationLevel: 3];
[dockMenu addItem: menuItem];
