Newt and dispose()

I encapsulated glWindows within a NewtCanvasAWT and in turn in a JFrame..

I noticed that whenever I click on the X to close it, dispose() is not called

Is this normal or is one problem of mine?

Hi

Use a WindowListener and call dispose() in the correct method by yourself. Maybe Sven could explain what the expected behavior is.

Calling destroy() on the NewtCanvasAWT seems working, it calls in turn dispose(). Thanks

You're welcome but I would like to know whether this is really the right thing to do. It works, it's fine :)

We attach an instance of AWTWindowClosingProtocol
to NewtCanvasAWT, with:
   ...
   * @param closingOperationClose mandatory closing operation, triggered if windowClosing and {@link WindowClosingMode#DISPOSE_ON_CLOSE}
   * @param closingOperationNOP optional closing operation, triggered if windowClosing and {@link WindowClosingMode#DO_NOTHING_ON_CLOSE}
   */
  public AWTWindowClosingProtocol(Component comp,
     Runnable closingOperationClose, Runnable closingOperationNOP) ...

The 'default closing operation' is initially fetched from the
NewtCanvasAWT's JFrame, if exists, or WindowConstants.DO_NOTHING_ON_CLOSE.

Users can override NewtCanvasAWT's 'default closing operation'.

NewtCanvasAWT's closing operations are:

WindowConstants.DO_NOTHING_ON_CLOSE (closingOperationClose):
  - detach the NEWT window from NewtCanvasAWT and
  - send NEWT WindowEvent.EVENT_WINDOW_DESTROY_NOTIFY

WindowClosingMode.DISPOSE_ON_CLOSE (closingOperationNOP):
  - send NEWT WindowEvent.EVENT_WINDOW_DESTROY_NOTIFY

Hence, the NEWT window can still be used by default after the AWT component
has been disposed/closed.

To dispose the Newt child w/ the AWT window, simply add a NEWT window listener
and issue dispose on the NEWT window.

Maybe not as intuitive, however still quite flexible.

I cannot add any window listener on the newtCanvasAWT, I dont have any method. But I do have on the glWindow

Yes, use a Newt WindowListener and override windowDestroyNotify.

so

glWindow.addWindowListener(new WindowAdapter() {

   @Override
   public void windowDestroyNotify(WindowEvent windowEvent){

   }
});


I dont have any dispose on the glWindow, should I call directly the dispose(GLAutoDrawable drawable)?

Why not calling destroy()?

Ok

I have confused the 2 above operations, they are of course vice versa:

NewtCanvasAWT's closing operations are:

WindowClosingMode.DISPOSE_ON_CLOSE (closingOperationClose):
  - detach the NEWT window from NewtCanvasAWT and
  - send NEWT WindowEvent.EVENT_WINDOW_DESTROY_NOTIFY

WindowConstants.DO_NOTHING_ON_CLOSE (closingOperationNOP):
  - send NEWT WindowEvent.EVENT_WINDOW_DESTROY_NOTIFY
