Re: Equivalent to javascript confirmdialog ind GWT

The solution is posted her on Stackoverflow. 

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 )

        {

        }

      } );

    }

  }

}
