[gl4java-usergroup] Destroying and Creating canvases in a single window ? ? ?

[Tobias L. G. <tg...@ul...>]

Hello all,

I am wondering whether or not anyone else is having trouble
destroying and creating GLCanvases in a single window.  I
have tried with both the binary release from Jausoft, and the
CVS release that was on sourceforge as of March 22, 2003.

I think that something is not being properly disposed of when
a GLCanvas is destroyed.  I am able to create and destroy
a few GLCanvases but after a while the GLCanvases that are
created slow to a crawl when drawing.

Try as I might, I have only been able
to find a single bug in GL4Java.  It is in the GLCanvas code,
during the first paint, the canvas adds itself to the top level
window as a listener.  The problem is, that it never removed
itself as a listener and so it would never get finalized.  This
is not even a bug if you look at it from the point of view of
always needing to destroy the top-level window in order to
destroy a GLCanvas, although in practice you end up having
to exit the program.  Be that as it may, I am at a loss for the
moment as to why this slow down is happening when I create
and destroy more than a few GLCanvases.  I am looking
through the GL4Java code again now, and I will find out why
sooner or later by the grace of VisualC, but if someone has a
clue, could you help a brotha out ? ? ?
