title: Copy and paste MessageDialog message
body: <p>I am creating a MessageDialog with some information.</p>
  
  <pre><code>MessageDialog.openInformation(getShell(), "Success", "Change "+getNumber()+" has been created.");
  </code></pre>
  
  <p>I am wanting to be able to copy the number in the dialog so I can paste it somewhere else. Is there a way to set the MessageDialog so I can accomplish this?</p>
  
  <p>The API can be found <a href="http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fjface%2Fdialogs%2FMessageDialog.html" rel="nofollow">here</a>. I have not found anything in the API that really helps me out.</p>
