Hello! Is there any way of checking if a GL context is made already current (gljMakeCurrent())? Calling gljMakeCurrent() twice crashes JVM, haven't checkeg gljFree() twice... but is there some clean way of checking it? BTW, is it possible to change GL4Java's behavior from crashing JVM to just throwing an exception in case of duplicate context activation? This is true for GL4J 2.4.0.0 and Sun's JVMs 1.2.2 and 1.3rc1 and IBM's 1.3 / Linux.

Hello Max.
1.
==
I tried to call several times gljmakeCurrent(true)
in the display method and I didn't get any crash
on Windows.
I use sun jvm from jdk 1.2.2.
2.
==
When I need to make gl call outside of display() method,
I use the following piece of code:
/////
synchronized(MyConstants.synchronizator)
// MyConstants.synchonizator is a static String used to
// synchronize all gl call.
{
if (canvas.gljmakeCurrent(true))
{
GLFunc gl = canvas.getGl();
GLUFunc glu = canvas.getGlu();
// Here all my gl calls...
// ....
canvas.glFree();
}
///////
Maybe it is too heavy code. I don't know if
gljmakeCurrent() and glFree() takes lot of time or not to execute.
3.
==
Anyway, I agree with you:
Checking if a GL context is made already current
would be nice.

Well, we can add a gljGetCurrentContext native function to GLContext. Also we may can add a gljMakeCurrentNoReplace thing to GLContext !

Shit, I cannot reproduce the bug right now. I thought it's so staightforward that it's not worth saving the code. Although I was able to crash JVM without problem. If it happens again I'll save this precious code ;-) Sorry then.

Hi *, does anybody know if it's possible to use texture compression with gl4java ? ciao, Thorsten |
