screen saver

[michaelhann89]

Does anyone know of a routine that will stop the screen saver from coming on in a canvas. i know there is no possible command to turn it off i am just after something that will stop if from coming on. maybe using a timer or something any help would be great thanxx

Hi michaellhann89,
Hope this will be useful for you

import com.nokia.mid.ui.DeviceControl;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;

public class BacklightWorkaround extends MIDlet {

private SimpleCanvas canvas;

/**
* Keeps the backlight on by repeatedly setting
*/
class LightThread extends Thread {
public void run() {
while(true){

DeviceControl.setLights(0, 100);
try {
Thread.sleep(5000);
} catch (InterruptedException ex) {
ex.printStackTrace();
}
}
}
}

private class SimpleCanvas extends Canvas implements CommandListener{
private Command exitCmd;
private MIDlet midlet;

public SimpleCanvas(MIDlet midlet) {
this.midlet = midlet;
exitCmd = new Command("Exit",Command.EXIT, 1);
addCommand(exitCmd);
setCommandListener(this);
}
public void paint(Graphics g) {
g.drawString("Let there be light.", 0, 0, Graphics.LEFT|Graphics.TOP);
}

public void commandAction(Command command, Displayable displayable) {
if(command == exitCmd){
midlet.notifyDestroyed();
}
}
}

public void startApp() {
if(canvas == null){
canvas = new SimpleCanvas(this);
new LightThread().start();
}

Display.getDisplay(this).setCurrent(canvas);
}

public void pauseApp() { }

public void destroyApp(boolean unconditional) { }
}

Thanks
