How to set an AppMenu using Glade?

[Hydexon <cristopher7sosa gmail com>]

Hello everyone i'm new here!, i just coding with Gtkmm and Glade for 
some time and i wan't to create an application following the 
Elementary's HIG's 

But this is a general question about glade, how to create an "app-bar", 
what means an toolbar button in the right side of the toolbar (only the 
app-bar button is under the right side of the toolbar) and my question 
How to put these button in the right side of the toolbar?


Thanks.
