[maemo-developers] Duplicating the Backlight statusbar app's "menu"

[From: adam at quo.com]

How does the backlight statusbar app include a HildonControlbar in what 
seems to be a GtkMenu?
I've tried packing the HildonControlbar into a GtkMenuItem, but it 
doesn't function correctly, as a click on it performs a menu item 
selection and closes the menu.

Am I going about this wrong? Does the backlight app use something  besides
a GtkMenu when clicked?

This is driving me nuts! Help/comments/tips/suggestions/anything very 
much appreciated. :)
