title: GWT Listbox Multi Select
body: <p>I need to add a listbox / combobox which allows the user to choose several values.</p>
  
  <p>I know there is one already available in the GWT API
  <a href="http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/ListBox.html" rel="nofollow">ListBox</a>
  with isMultipleSelect() set to true. But I am not getting any direct way to get all selected reocrds from list box.</p>
  
  <p>Some tutorials on google are sugeesting implement <code>ChangeHandler</code>'s <code>onChange</code>method.</p>
  
  <p>I think there should be some other way.</p>
  
  <p>Any pointers would be appreciated.</p>
