As with the example in Chapter 1, Creating Your First Plug-in, this will open a message dialog to verify that it works as expected:

    treeViewer.addDoubleClickListener(event -> {
        Viewer viewer = event.getViewer();
        Shell shell = viewer.getControl().getShell();
        MessageDialog.openInformation(shell, "Double click",
         "Double click detected");
    });
  2. Run the target Eclipse instance, and open the Time Zone Tree View. Double-click on the tree, and a shell will be displayed with the message Double click detected....
