title: How to fill the group SWT widget with necessary details inside the border
body: <p>I'm having a tree View and I'm having a group named 'Details' which displays the details of the selected item (when selected) in the tree view.</p>
  
  <p>I'm unable to set the string inside the group border, when using the SWT Groups.
  I'm able to only set the Title using the "group.setText()" method which sets the title for the group.</p>
  
  <pre><code>    --Details-----------------
     |                          |
     |  item 1 is selected      |
     |                          |
      --------------------------
  </code></pre>
  
  <p>I want to display the selection as shown in the above Figure.</p>
