Hi,
you have to catch the exit event in the commandAction method and there you will display a YES/No form:
create your YES/NO form:
Form yesNoForm = new Form("Exit?");
yesNoForm.append("You are about to exit the application!Exit?")
yesNoForm.addCommand(new Command("Yes",Command.OK,1));
yesNoForm.addCommand(new Command("Cancel",Command.CANCEL,0));
yesNoForm.setCommandListener(this);
!!!Note you can write your own command classes extended from the Command and add those to yesNoForm, that way you will have a better control on the application.
commandAction(Command c, Displayable d){
if (c.getCommandType() == Command.EXIT) {
display.setCurrent(yesNoForm);
if(c.getCommandType() == Command.OK){
destroyApp(true);
notifyDestroyed();
if(c.getCommandType() == Command.CANCEL){
display.setCurrent(mainForm);
This should work.
