title: VirtualStringTree OnNodeRightClick
body: <p>I am looking for a procedure or something that gets fired if I right click on a Node (or in general on the VirtualStringTree)</p>
  
  <p>I have the following scenario:</p>
  
  <ul>
  <li>I have my VST close to a listview.</li>
  <li>I can only multi select root nodes with the mouse (hold mousebutton and move the mouse)</li>
  <li>If I click on ANY child node (right or left) - it is selected (+ [VSelected] State)</li>
  <li>If I right click on a root node it selects automatically and opens a popupmenu.</li>
  </ul>
  
  <p>Now I would like to have a different popupmenu for ( 1 common ) for all my child nodes (and only if they are selected).</p>
  
  <p>Hope you can understand what I mean, thank your for your help.</p>
