Hi,

playing around with the nifty-gui, I wanted to put all the theory in a practical example and see how it performs/looks like..

I choose something simple, the frozen bubble game

I am trying to set up a basic scenario, I dont want to have an animator, I want to update the screen on explicit command

So far this is the main class

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
package core;

/**
 *
 * @author gbarbieri
 */
public class FrozenBubble {
   
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
       
        Rendering rendering = new Rendering();
    }
}

And the rendering class

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
package core;

import com.jogamp.newt.opengl.GLWindow;
import javax.media.opengl.GLAutoDrawable;
import javax.media.opengl.GLCapabilities;
import javax.media.opengl.GLEventListener;
import javax.media.opengl.GLProfile;

/**
 *
 * @author gbarbieri
 */
public class Rendering implements GLEventListener{

    private GLWindow glWindow;
   
    public Rendering() {

        initGL();
    }

    private void initGL() {

        GLProfile profile = GLProfile.get(GLProfile.GL3);
        GLCapabilities capabilities = new GLCapabilities(profile);
        glWindow = GLWindow.create(capabilities);

        glWindow.setAutoSwapBufferMode(true);
       
        glWindow.setSize(800, 600);

        glWindow.addGLEventListener(this);
       
        glWindow.setTitle("Frozen Bubble");
       
        glWindow.setVisible(true);
    }
   
    @Override
    public void init(GLAutoDrawable drawable) {
        System.out.println("init");
    }

    @Override
    public void dispose(GLAutoDrawable drawable) {
        System.out.println("dispose");
    }

    @Override
    public void display(GLAutoDrawable drawable) {
        System.out.println("display");
    }

    @Override
    public void reshape(GLAutoDrawable drawable, int x, int y, int width, int height) {
        System.out.println("reshape");
    }    
}

The program shows the windows and shutdowns, obviously

The called methods are init, display and dispose

How can I set up in order the system to wait (on some user actions through the nifty-gui?)
