Hi, i am new to java and game development.

I just started creating my first java applet using JOGL library.
After few tutorials i managed to draw a triangle, but have problem with GLCanvas and the reshape method.

        public class CMain extends Applet implements GLEventListener
....

   public void init()
   {
      glu = new GLU();
      canvas = new GLCanvas(new GLCapabilities(GLProfile.getDefault()));
      this.add(canvas);
     
      canvas.addGLEventListener(this);
      canvas.setPreferredSize(this.getSize());
     
      final FPSAnimator animator = new FPSAnimator(canvas, 60);
      animator.start();
   }

....

   public void reshape(GLAutoDrawable glDrawable, int x, int y, int w, int h)
   {
         GL2 gl = glDrawable.getGL().getGL2();
         
         h = (h == 0) ? 1 : h;  // Prevent divide by zero
        float aspect = (float)w / h; // Compute aspect ratio
       
         // Set view port to cover full screen
        gl.glViewport(0, 0, w, h);
         
         // Set up the projection matrix - choose perspective view
        gl.glMatrixMode(GLMatrixFunc.GL_PROJECTION);  
         gl.glLoadIdentity();    // reset
        glu.gluPerspective(45.0f, aspect, 0.1f, 100.0f);
         
         // Switch to the model-view transform
        gl.glMatrixMode(GLMatrixFunc.GL_MODELVIEW);
         gl.glLoadIdentity();    
         
         canvas.setPreferredSize(null);
         canvas.setPreferredSize(this.getSize());  // <--- hmmm
  }

I don't know much about applets. I didn't think you could re-size it. The problem may be in the repaint() method. How are you handling that in the applet?

fixed Smiley

replaced canvas.setPreferedSize() with canvas.reshape().
eclipse doesn't have javadoc for that method, it has 4 parameters so i guessed that would be x,y,width,and height.

canvas.reshape(0, 0, this.getWidth(), this.getHeight());
