Re: [gl4java-usergroup] Problem with GL4Java v2.2.0.0

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

Dear GL4Java Users,

I am sorry for your inconvinience !

There IS a bug in the WINDOWS version for SUN/Netscape JVM Only,
while resizing the canvas/window !

The prototype in gl4java.GLContext is:

    private final native void gljResizeNative( boolean isOwnWindow,
				               int disp, int thisWin,
				               int width, int height );

The native implementation for Windows is:

	JNIEXPORT void JNICALL
	Java_gl4java_GLContext_gljResizeNative( JNIEnv *env, jobject obj,
				        jint width, jint height)
	{
	}

So the native functions could not be found in the native library !

I send you a temporaery java-bugfix 
for the !!!!! WINDOWS version for SUN/Netscape JVM ONLY !!!!,
because I am at a customer and I do not have a Win32 compiler avaiable
:-(
Next weekend, I will release the bugfix (new Win32 library) on the
website !

I only add the binaries
	gl4java/GLContext.class
	gl4java/GLContext$1.class
	gl4java/GLContext$2.class
to the zip - archive !

Please patch the gl4java.jar files by yourself for this moment !

- OR do not RESIZE !

The source changes for gl4java/GLContext.java.skel:
---------------------------------------------------------------------------
    public final void gljResize(int width, int height)
    {
    	if ( ! isInitialized || !glEnabled ) return;

	if ( useMSJDirect )
        {
		try
		{
			Point p = _comp.getLocationOnScreen();
			gl4java.system.GljMSJDirect.moveOGLWindowNative(
					     windowHandle,p.x,p.y,width,height);
		}
		catch (Exception e)
		{ }
	}
        else 
                gljResizeNative( width,height);
    }

    private final native void gljResizeNative( int width, int height );
---------------------------------------------------------------------------

Please remind, 
that this patch works for the !!!!! WINDOWS version for SUN/Netscape JVM
ONLY !!!!

THANXS !

Happy hunting !

Yours, Sven Goethel
