Bug 50

---- Reported by fsk456 2003-11-20 00:16:59 ----

Creating a GLCanvas inside the AWT thread (e.g. from a swing component),
fails when a resize/reshape of the GLCanvas is triggered.

Example:
I open a JFrame with a JButton inside that, when pressed, triggers the creation
of a GLCanvas that is added to the frame's content pane.
When the creation of the GLCanvas triggers a reshape (I call setSize), I get the
following exception:
net.java.games.jogl.GLException: Unable to lock surface  
(stack trace at end).
 
A workaround that I found is to create a new thread in the actionPerformed of
the button-listener (AWT thread), create the GLCanvas in the new thread, while
the AWT thread is waiting for the new thread to finish.

I've got a modifed gears demo that shows the issue.
I'll try to attach it to this issue.

This issue has been fixed in one of the more recent JOGL builds. The root cause
was probably proper understanding of exactly when the underlying AWT component
had been realized. Since I don't know the exact root cause I'm marking it "works
for me"; please open another bug if similar problems surface.
