NSPopUpButtonCell with hierarchical menu in NSTableView

Question

I have an NSTableView of which one column contains NSPopUpButtonCells. This column is assigned to an IBOutlet. My application's controller class creates a menu in it's init and assigns it to the NSTableColumn's dataCell, which is the NSPopUpButtonCell.

The menu looks as follows:

NSPopUpButton
    NSMenu
        NSMenuItem item1
        NSMenuItem item2
        NSMenuItem item3
            NSMenu
                NSMenuItem item3_1
                NSMenuItem item3_2
        NSMenuItem item4
                NSMenuItem item4_1
                NSMenuItem item4_2
                NSMenuItem item4_3

When I click the menu and choose item1 or item2, my data source's tableView:setObjectValue:forTableColumn:row: is fired and the objectValue is 0 or 1, the index of the chosen item. However, when I pick an item from one of the submenus, the objectValue I get is -1. How would I be able to get the menu item which was chosen?

Is your popup button in pull-down mode or pop-up mode? – Wil Shipley Mar 18 '11 at 10:46 — Wil Shipley, Mar 18 '11 at 10:46

I don't think I'd rely on -tableView:setObjectValue:forTableColumn:row: when you have a complex set of menus and submenus; if I recall correctly there isn't really an 'object value' to menu item mapping when submenus come into play -- NSMenu is too old to use NSIndexPath like you might hope, and isn't complex enough to try to map integers to menus and submenus. (Plus, menus tend to change a lot dynamically, so the meaning of "3" would be pretty squirmy.)

Set a target and action on your NSMenuItems (or possibly just the parent NSMenus) to do something reliable when each is selected.

Are you using the same code as you are to retrieve item 1 and 2? I suppose you are, but sometimes these things are easily overlooked =/
