[gl4java-usergroup] removing GlCanvas

[Dave G. <da...@sm...>]

Hi there

Quick (and probably stupid) question:

I am having problems removing a GLCanvas from an applet space.
The sequence is as follows:

(+) create the applet space
(+) create myGLCanvas at (say) 75% of applet width and height (in this =
instance, myGLCanvas is a GLAnimCanvas which is not using drawlists)
(+) add(myGLCanvas)
(+) start myGLCanvas on some keypress
(+) stop myGLCanvas  on some keypress
(+) Now, when I hit some other key, I want the GLCanvas to shut down, =
and remove itself from the applet space. But the following code does not =
work -- it leaves the GLCanvas on the screen, and right at the front of =
the z-priority:


public void canvasDestroy(GLCanvas canvas)
{
  remove(canvas);
  canvas.stop();
  canvas.destroy();
  layout();
}


FYI, canvas.destroy() is as follows (note I have copied the glj* calls =
to ensure they fire):

public void destroy()
{
  glj.gljFree();
  glj.setEnabled(false);
  glj.gljDestroy();

  cvsDispose();
}


I have tried mucking about with Containers and ComponentPeers but I =
still cannot get GLCanvas or GLAnimCanvas to release its draw space. Is =
there something obvious that I am doing wrong?

Any help would be much appreciated!
Cheers,

Dave.
