Using Piccolo for Drawing

[rstepler]

I am using piccolo to create a drawing. I want to place the canvas (DrawCanvas) into a JPanel (SimulationPanel). The canvas's drawings are not appearing. I have posted my code below. Are there any suggestions? Thanks for your help.

Code:

public class CohortGui extends JFrame {
	public CohortGui () {
		super("Simulation");
		setSize(1400,850);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		Thread runner;
	// GUI menu
		JMenu fileMenu = new JMenu("File");
		JMenu simulationMenu = new JMenu("Simulation");
		JMenu optionMenu = new JMenu("Option");
		JMenu aboutMenu = new JMenu("About");
 
		JMenuBar menuBar = new JMenuBar();
			menuBar.add(fileMenu);
			menuBar.add(simulationMenu);
			menuBar.add(optionMenu);
			menuBar.add(aboutMenu);
		setJMenuBar(menuBar);
	// Create DrawCanvas
		DrawCanvas drawArea = new DrawCanvas();	
	//Create simulationPanel
		SimulationPanel sp = new SimulationPanel();
		sp.setBackground(Color.white);
		sp.add(drawArea); 
		add(sp);



..........


class DrawCanvas extends PCanvas {
	public DrawCanvas(){
		PLayer layer = new PLayer(); 
		PCamera camera = new PCamera();
		layer.addCamera(camera); 
		//Create Lines
		LineOne one = new LineOne();
		LineTwo two = new LineTwo();
		LineThree three = new LineThree();	
		PLine test = new PLine();
		test.setBounds(100,200,200,400);
		
		PImage ngo = new PImage("C:/Users/Renee/Desktop/toolbarButtonGraphics/INET_Earth_Clear.png");
		ngo.setBounds(390, 75, getAlignmentX(), getAlignmentY());
		layer.addChild(ngo);
		PImage ngo2 = new PImage("C:/Users/Renee/Desktop/toolbarButtonGraphics/INET_Earth_Clear.png");
		ngo2.setBounds(110,300,getAlignmentX(), getAlignmentY());
		layer.addChild(ngo2);
		PImage ngo3 = new PImage("C:/Users/Renee/Desktop/toolbarButtonGraphics/INET_Earth_Clear.png");
		ngo3.setBounds(730,300, getAlignmentX(), getAlignmentY()); 
		layer.addChild(ngo3); 
		
		layer.setPaint(Color.BLACK);
		layer.addChild(one);
		layer.addChild(two);
		layer.addChild(three);
		layer.addChild(test); 		
		
	}
}
class SimulationPanel extends JPanel {
	public SimulationPanel () {
		setLayout(null); 
		JLabel testLabel= new JLabel("Test Label");
		add(testLabel); 
		
		
	}
}
