title: Eclipse Plugin - get Launch Configurations Tree List in a Dialog.
body: <p>I'm currently trying to get the red part of the "RunConfigurations..." window, (see img 1.1)
  into an TitleAreaDialog (see img 1.2).
  The final result should look like this:  (see img 1.3)</p>

  <p>With the plugin "Spy" I found some useful information:
  The "Run Configurations..." window (img 1.1) is created in the class: "LaunchConfigurationsDialog" which has a "LaunchConfigurationView" as an attribute (note: this attribute is a class).
  Within this private attribute you find a "LaunchConfigurationFilteredTree" attribute (note: yet another class).</p>
  
  <p>I think, that this last attribute is what I'm looking for. But I can't figure out which methods I have to override to be able to show this FilteredTreeList with all Launch Configurations in my CustomTitleAreaDialog. </p>
  
  <p>Thanks in advance for your help!</p>
