it's true. I'll investigate this path ... ;)

I was afraid somebody would suggest something like this to me. 

*Explaination*: I'm developing an embedded linux app that uses
customized GTK as graphical toolkit (see www.maemo.org to more
informations). No problems until this point. So somebody sent the
following e-mail to the respective mail list:

ANSWER from the list : Make an item with the same name to all the
menus, and connect the same callback to both/all of them. This is the
only way to do this
currently, in the future you can do it with *GtkUIManager* magic, but
that's in the future...

:( so , there is no 'gtk_ui_manager_get_ui' available. I have try
found out another way ...

ps2: Thanks again Tristan.
