Cannot find symbol: GLAutoDrawable

Can’t seem to find the GLAutoDrawable :S
Anyone know the reason?

Code:




    public void init(GLAutoDrawable drawable) {
        GL gl = drawable.getGL();

        gl.glClearColor(0, 0, 0, 0);
        gl.glMatrixMode(GL.GL_PROJECTION);
        gl.glLoadIdentity();
        gl.glOrtho(0, 1, 0, 1, -1, 1);
    }

Whole code: I changed others that said GLAutoDrawable to GLDrawable to see if that would work -.-

A lot has changed … I don’t believe the code you have meets the latest JOGL specification…it might be JOGL 1.0 or pre.

For example, JOGL imports look something like this now:


import javax.media.opengl.*;

no more of the net.java.games.jogl…you’ll have to upgrade your code.
