I'm trying to get the objects I draw on the screen when I press the up and down arrows. This is the code I have so far but I don't know how to call redrawRoom() from the keyPressed() method.

import java.awt.Frame;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.media.opengl.*;
import javax.media.opengl.awt.GLCanvas;
import javax.media.opengl.glu.GLU;

import com.jogamp.newt.event.KeyEvent;
import com.jogamp.newt.event.KeyListener;
import com.jogamp.opengl.util.gl2.GLUT;

public class CGGame implements GLEventListener, KeyListener{
	
	private int w, h, z;
	private GLU glu;
	private GLUT glut;
	private GLAutoDrawable draw = null;

	
	public CGGame(){
	}
	
	public static void main(String[] args){
		GLProfile.initSingleton(false);
		GLProfile glp = GLProfile.getDefault();
		GLCapabilities caps = new GLCapabilities(glp);
		GLCanvas canvas = new GLCanvas(caps);
		canvas.addGLEventListener(new CGGame());
		Frame frame = new Frame("CG Game");
		frame.setSize(520, 640);
		frame.setVisible(true);
		frame.add(canvas);
		
		frame.addWindowListener(new WindowAdapter(){
			public void windowClosing(WindowEvent e){
				System.exit(0);
			}
		});
	}
	
	
	@Override
	//this function will hold the code for drawing the room
	public void display(GLAutoDrawable drawable) {
			GL2 gl = drawable.getGL().getGL2();
	        
	        w = drawable.getWidth();
	        h = drawable.getHeight();
	        
	        gl.glClear(GL2.GL_COLOR_BUFFER_BIT|GL2.GL_DEPTH_BUFFER_BIT);			
	          
	        gl.glViewport(0, 0, w, h);											
	        
	        gl.glMatrixMode(GL2.GL_PROJECTION);									
	        gl.glLoadIdentity();

	//looks like each time they start the game, or advance to the next level
