Skinning How To/Edit a menu

Introduction

• All viewer menu options are set in menu_viewer.xml except for the Advanced/Admin menus (see VWR-2896).
• Width/height/bottom/left/top are irrelevant in the menu files. The viewer constructs menus based on the xml file's organization and ignores these parameters.
• Example menu structure:

<menu>
     <menu_item_call>
          <on_click>
     </menu_item_call>
     <menu> 
          <menu_item_check> 
               <on_check>
          </menu_item_check>
          <menu_item_call> 
               <on_click>
               <on_enable>
          </menu_item_call>
     </menu>
</menu>

• Changing the name of the Tools menu will make it not auto-hide.

Optional. Sets whether or not the menu can be torn off (the double bars at the top of a menu). Use in <menu>. Boolean: tear_off="true"

opaque

Changing a menu

• If you're adding a shortcut, make sure it isn't used by another item first.
• Renaming a menu or menu item is fine as long as it calls a working function.
• Any number of top level menus, flyout menus, and menu items can be set.
• Don't worry about width/height/bottom/left/top. As said in the intro, these don't do anything anymore.
• If you want to create a new menu item that doesn't call an existing function, you need to edit the source as well. See Adding_a_menu_item for a start.
