Help me for touch Screen Event Handling

[nil.bagul]

I am Using Netbeans for my coading with Qearty device to achive a touch screen support. i have write one prog but it wont work for Pointerpressed events in J2ME Plese help me My code is Below..


package hello;


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

/*
A quick sample of graphics, commands, and event handling.
*/

public class PointerExample extends MIDlet implements CommandListener
{
Display display;
Command exitCommand;
Command backCommand;
Command okCommand;
SampleCanvas sample; // Instance of sample canvas

List itemMenu;
Ticker ticker;
Alert alert;
Form form;
StringItem stringItem;



public PointerExample() {
display = Display.getDisplay(this);
exitCommand = new Command("Exit", Command.EXIT, 1);
backCommand = new Command("Back", Command.BACK, 2);
okCommand = new Command("OK", Command.OK, 3);

ticker = new Ticker("Here is Pointer Demo.");
itemMenu = new List(null, Choice.IMPLICIT);

itemMenu.append("Canvas", null);
itemMenu.setCommandListener(this);
itemMenu.addCommand(exitCommand);
itemMenu.setTicker(ticker);
display.setCurrent(itemMenu);
}

public void startApp () {
}

public void destroyApp (boolean unconditional) {
}

public void pauseApp () {
}

public void commandAction(Command c, Displayable s)
{
if (c == backCommand)
{
display.setCurrent(itemMenu);
}

else if (s == itemMenu)
{
if (c == List.SELECT_COMMAND)
{
int i = itemMenu.getSelectedIndex();
switch (i)
{
case 0: // Show Sample canvas
display.setCurrent(getCanvas());
break;
}

}
}
else if (c == exitCommand)
{
notifyDestroyed();
}

}

SampleCanvas getCanvas()
{
if (sample == null)
{
sample = new SampleCanvas();
sample.addCommand(backCommand);
sample.setCommandListener(this);
}
return sample;
}

}

Which touch screen device and its Java implementation are you targeting, exactly?

If it not a Nokia device, perhaps you could try the correct manufacturer's developer support?
