[gl4java-usergroup] Overriding the 'Exit' button...

[Powell, M. A. <Mar...@ps...>]

Hi all,

I have a canvas with a GLEventListener associated with it. This canvas
is inside a AWT.Panel, which is inside a AWT.Frame. I overrode the
default window listener with the following:

-------

app.addWindowListener(new WindowAdapter() {

            public void windowClosed(WindowEvent e) {

            }

            public void windowClosing(WindowEvent e) {

                ExitDialog exitDialog =3D new ExitDialog(app, "Are you
sure?");

            }

        });

--------

where ExitDialog extends AWT.Dialog. The hope was the put the basic: Are
you sure? Yes No. Dialog for closing.=20

The dialog works, hitting yes closes the application while no just
closes the dialog... however, as soon as I hit the 'X' button of the
Frame, I get:=20

gljDestroy failed (free) and the canvas no longer renders.

Is canvas listening to the window closing event as well? How do I fix
this?

Thank you,

Mark
