[Gtk-sharp-list] Disabling UIManager Actions

[LiamDyalog]

I know this is stale but for anyone coming across this now there is actually
a way to get the UIManager.GetAction() function to retrieve the action
you're looking for. You need to give it the path of a "proxy widget"
connected to the action that you're trying to access.

For example, imagine you have a simple MenuBar:
- MenuBar
  - HelpMenu
    - About

The xml might look like:
<ui>
  <menubar name='MenuBar'>
    <menu action='HelpMenu'>
      <menuitem action='About'/>
    </menu>
  </menubar>
</ui>

The path you need to pass to the GetAction function:
var action = uiManager.GetAction("/MenuBar/HelpMenu/About"); // The leading
forward slash is important

At which point you could set the sensitivity from the variable you have etc.
