Re: Equivalent to javascript confirmdialog ind GWT

You could use event.preventDefault() in onWindowClosing method,
display custom dialog box and if user confirmed close logout him.

And here is my code (it's only a extract of the full class) :

public class MainPresenter<V extends MainView>

    extends BasicPresenter<V>

    implements HistoryTokens, MainViewControl, LoginEventHandler, Window.ClosingHandler,

    CloseHandler<Window>

{

 ....

 Window.addWindowClosingHandler( this );

    Window.addCloseHandler( this );

....

  /**

   * Diese Methode wird naufgerufen wenn das Browsertab geschlossen werden soll

   */

  @Override

  public void onWindowClosing( ClosingEvent in_event )

  {

    if ( model.isUserlogin() )

    {

      in_event.setMessage( CONSTANTS.web_client_MainPresenter_AenderungenSpeichernHinweis() );

    }

  }

  /**

   * Diese Methode wird naufgerufen wenn das Browsertab geschlossen wird

   */

  @Override

  public void onClose( CloseEvent<Window> event )

  {

    if ( model.isUserlogin() )

    {

      camWebServiceAsync.logout( new AsyncCallback<Void>()

      {

        @Override

        public void onSuccess( Void in_result )

        {

          

        }

        @Override

        public void onFailure( Throwable in_caught )

        {

        }

      } );

    }

  }

}
