[gl4java-usergroup] Re: debugging gljswap / Bug- and Problem Protocol

[Sven G. <sgo...@ja...>]

DEAR PAULSISK,

is this your name ? 
I do cc this response to the gl4java mailinglist.

Bug- and Problem Protocol
==========================
If sombody has a bug / problem,
please send a compileable piece (100-200 lines) of code,
which documents your problem !
Also send some information about the version (GL4Java, OS, OpenGL
renderer, ...) !

debugging gljswap 
==================
Well, "GLContext.gljSwap" calls its native method
"GLContext.gljSwapNative" which is defined 
e.g. in "CNativeCode/OpenGL_X11.c" or "CNativeCode/OpenGL_Win32.c" !
This function just calls glxSwapBuffers, or SwapBuffers, etc..

To be able to call "gljSwap", you must own a valid GLContext.
Please look into the demos and the docus (latex/html docu&java-api).

Example:
========

public void display()
{
	if(glj.gljMakeCurrent(true) == false)
	{
		return ; // error
	}

	/* your render stuff for one frame */

	glj.gljSwap();
	glj.gljFree();
}
