[gl4java-usergroup] destructor for glanimcanvas

[Kerstin M. <km...@gm...>]

hello,

i'm trying to write a gl4java program that works with matlab. the  
application runs (with GlAnimCanvas in a Frame), but i have some problems  
with closing them. when i click the cross (or ALT+F4) an error message  
occurs: "gljDestroy failed (free)". i read the forum and there they said i  
should stop the canvas (animcanvas.stop()) and i should  
animcanvas.destroy() but it won't work. the curious is, when i DON'T add  
any windowlistener to the frame and i click the cross, then the error  
message appears anyway and the canvas kind of destroy themself but the  
frame is still open. normally nothing should happen, because i didn't add  
some eventlistener.

apart from that. i think something is left in the memory. when i start the  
application with matlab by calling the constructor of the class (its very  
easy to work with the combination matlab and java) and close them and  
start them again and again. after the 3th or 4th time running the program,  
the animation gets slower and slower and finally perhaps after the 5th  
time starting it. matlab and the javaapplication crashes. so i thougth, i  
could use a destructor that free the memory especially the opengl things.  
how can i do that?

thanks for trying to understand my english :-)
i hope you can help me
