import javax.microedition.lcdui.Graphics;

public class MainCanvas extends Canvas {
	static MainCanvas mainCanvas;

	public MainCanvas() {
		mainCanvas = this;
	}

	DemoCanvas c = new DemoCanvas();

	protected void paint(Graphics g) {
		c.paint(g);
	}

	public static Canvas getMainCanvas() {
		return mainCanvas;
	}

	public void keyPressed(int keyCode) {

		System.out.println(keyCode
				+ " "
				+ (keyCode = keyCode < 0 ? this.getGameAction(keyCode)
						: keyCode));
		c.keyPressed(keyCode);
	}

	public void keyReleased(int keyCode) {
		c.keyReleased(keyCode);
	}

	public void input() {
		c.input1();
		this.repaint();
