Thank you Keary. In the meantime I dismissed that NSPopUpButton and put a simple button + a NSTextField aside. They look as a group. When I click on the button I create on the fly a NSPopUpButtonCell and pop it up with performClickWithFrame: Then when the user selects a menu item, the menu item invokes its target-action and I get the menuItem tag and title then I put that title within the NSTextField. I release the NSPopUpButtonCell. Done.
The thing I have still to do is: when the user pops up the menu, I should select and display the latest selected menuItem, opening all of its parents' menu. And I don't know how to do that. Do you have an idea? The purpose is: I have a short hierarchical tree of objects, and the user should be able to choose an object quickly, without opening other panels.
