title: how to register KeyStroke on JXDatePicker
body: <p>I need to transfer focus onto another element when user press Enter key, so I succeded to register KeyStroke on most elements this way: </p>
  
  <pre><code> this.getInputMap( ).put( KeyStroke.getKeyStroke( '\n' ), "transferFokus" );
  
    this.getActionMap( ).put( "transferFokus", transferFokusa );
  </code></pre>
  
  <p>everything works fine except for my class which extends JXDatePicker which I suppose consumes Enter key inside. What can I do? </p>
  
  <p>The whole point is to ease people using GUI interface, since they've worked on old DOS application in which they where moving inside form with Enter instead of TAB key.</p>
