– Re: GLJPanel on JInternalFrame

thank you for the test case and the good description.
I'll take a look at it after SIGGRAPH.
sure, feel free to file a bug report.

I just wanted to point out the fact that I reproduced this
painting issue with a GLJPanel in a top level JFrame. This is the
proof that the bug is not related to the use of JInternalFrame.
Here is a very simple application that reproduces the bug:
public final class TestApp implements GLEventListener
public static void main(final String inArguments)
JFrame frame = new JFrame();
javax.media.opengl.awt.GLJPanel canvas = new
// Give frame the screen size as initial size.
Dimension screenSize =
public void display(GLAutoDrawable arg0)
GL2 gl = arg0.getGL().getGL2();
// Simply draw something: a green triangle on a
gl.glClearColor(1.0f, 0.0f, 0.0f, 1.0f);
gl.glColor3f(0.0f, 1.0f, 0.0f);
public void dispose(GLAutoDrawable arg0)
public void init(GLAutoDrawable arg0)
public void reshape(GLAutoDrawable arg0, int arg1, int
arg2, int arg3, int arg4)
On my computer, here is what I witness on my 1680x1050 screen:
-at startup the GLJPanel is properly painted from its left bound
til the 1024th pixel. At the right of this limit, the panel is
-when I reduce panel's height below 400 pixels, the properly
painted portion's width lowers to 512 pixels. From that point,
when I increase panel's height again, the portion's becomes 1024
pixel wide again when panel's height exceeds 512 pixels.
-if I keep on reducing panel's height, the painted portion's width
reduces to 256, then 128, then 64 pixels, etc...
I hope this code sample will help. I would be happy to file a bug
in Bugzilla or to perform other investigation if you feel like it
could be useful.
Thanks again for your help.
