The Main Window Branch
From the Main Window node, you can add the following nodes:
A Menu Bar and a Toolbar, if you have selected Classic menu from the Menu type list in the Settings window for the Main Window node.
A File Menu, if you have selected Ribbon from the Menu type list in the Settings window for the Main Window node. A Ribbon node is always available, to which you can add Ribbon Tab and Ribbon Section nodes.
You can also choose these items from the Main Window contextual toolbar (see The Main Window Toolbar below) and get a preview of the added items in the Main Window window.
