gnome_app_insert_menus

[paul sanford toney <pst stilton com>]

hello list,

i've recently begun gnome programming with a smallish mdi app, and i'm having a
little problem. let me briefly explain what's going on:

when i create my mdi top-level object, it is of course using the menubar and
toolbar templates i've designated; however, i have some dynamically assigned
menu items loaded in from a config file on startup which need to get inserted
here and there. so on startup, i generate a list of these dynamic menu items,
and then catch the mdi `app-created` signal to insert the menus after the app
menus have been instantiated from the template.

here's the problem. all of this actually works, the dynamic menus show up, even
when i drag a notebook tab out to spawn a new top-level. however, when i select
one of the dynamically-installed menu items and my callback function is invoked,
the user_data parameter gets hosed. in the sample code below, i've set it to
0xdeadbeef; by the time it gets to my callback function, it's something else.

any ideas?

also, i'm not sure whether i should assume that gnome_app_insert_menus_with_data
(...) will make a deep copy of the menuinfo structures, so i'm g_strdup'ing the
menu label.

i suppose i could trace through all of this in the debugger, but i thought
before i took that step, somebody might have some insights. any help would be
greatly appreciated. thanks!

        but it's not - say it ain't so! */
