Hai Friends,

Iam using canvas class in my J2ME progrm,it does show full screen view in mobile, i want to show j2Me form to full mobile screen, please help me for this problem.

Not possible. Option of full screen is available only to Canvas and GameCanvas

Iam using Gamecanvas only but it does not displaying for full mobile screen.
my code is here

import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;
import javax.microedition.midlet.*;

public class CanvasGame extends MIDlet{

    private Command back;
    private Display display;
    final SweepGame game = new SweepGame();

    public void startApp() {
        back = new Command("Back", Command.BACK, 0);
        game.start();
        game.addCommand(back);
        game.setCommandListener(new CommandListener(){
            public void commandAction(Command c, Displayable s) {
                game.stop();
                notifyDestroyed();
            }
        });
        display = Display.getDisplay(this);
        display.setCurrent(game);
    }

    public void pauseApp() {}

    public void destroyApp(boolean unconditional) {}
}

class SweepGame extends GameCanvas implements Runnable {
    private boolean move;
    private int radius;
    private int diameter;
    private int interval;

    public SweepGame() {
        super(true);
        radius = 0;
        diameter = 10;
        interval = 0;
    }
    public void start() {
        move = true;
        Thread t = new Thread(this);
        t.start();
    }
    public void stop() {
        move = false;
    }
    public void render(Graphics g) {
        int width = getWidth();
        int height = getHeight();
        g.setColor(183,251,121);
        g.fillRect(0, 0, width - 1, height - 1);
        int x = diameter;
        int y = diameter;
        int w = width - diameter * 2;
        int h = height - diameter * 2;
        for (int i = 0; i < 17; i=i+2) {
            g.setColor(((17 - i) * 15 - 7),20,((17 - i) * 15 - 7));
            g.fillArc(x, y, w, h, radius + i * 10, 10);
            g.fillArc(x, y, w, h, (radius + 180) % 360 + i * 10, 10);
        }
    }
    public void run() {
        Graphics g = getGraphics();
        while (move) {
            radius = (radius + 1) % 360;
            render(g);
            flushGraphics();
            try {
                Thread.sleep(interval);
            }
            catch (InterruptedException ie) {}
        }
    }
}

I think there is a method called setFullScreen(boolean value) that you can use.

Yeap, just add setFullScreenMode(true); to any Canvas class in declaration like bellow and you done

public SweepGame() {
        super(true);
        setFullScreenMode(true);
        radius = 0;
        diameter = 10;
        interval = 0;
    }

PS: Use of code tags with your post count should be one of MUST DO!
