Skinning How To/Edit a menu

menu_viewer.xml

• All menu options are set in menu_viewer.xml (except for the Advanced/Admin menus--see VWR-2896).
• Width/height/bottom/left/top are irrelevant. The viewer constructs the menu 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>

Parameters

enabled

Sets whether or not a menu is enabled or not. Use in <menu>. Boolean: enabled="true"

name

Sets the name the user sees. Necessary for <menu> and menu items. String: name="Awesome Menu"

label

Sets the name the viewer sees. Necessary for <menu> and menu items. String: name="LabelMenuAwesome"

• Changing the label for the Tools menu will make it not auto-hide.

tear_off

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

Optional. Sets whether or not the menu is opaque (setting a stop level menu to false will turn the entire menu transparent unless torn off and reattached. Setting the menu bar to false will turn it transparent per settings in colors.xml). Use in <menu>. Boolean: opaque="true"

userdata

Optional. Any data sent to the function. Use in <on_click>, etc. String: userdata="800,600"

function

Associates a function with a menu item and action. Use in <on_click>, etc. String: function="Tools.SelectedScriptAction"

shortcut

Optional. Sets the keyboard shortcut for a menu item. Each key is separated by pipes. String: shortcut="control|alt|T"

Changing the menu

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