Looking at the data structure where the menu item label is taken from, its a GtkLabel, and according to gail's code, it only has a call to get the name, not to set it. Its also worth mentioning that the icon and label for the menu item are packed into a box, using gtk_pack_box_start etc. I'm going to have to think carefully about how to present more information than what the label provides. In this case, its not appropriate to extend/change what the label shows to the user visually?

 

One way to fix this is to set the accessibility object's name in GUI's code, I mean, where the label is implemented. GAIL only considers the general use of Gtk+ objects. If any application wants to provide more accessibility information, it can set accessibility object's name in their own code.

Yes I am aware of this. One thing I tend to forget however, is that some atk implementations for gtk widgets only allow one to get the name, and not set it. :)

Like I said, set accessibility name in GUI code would be an option.
