extends MIDlet implements javax.microedition.lcdui.CommandListener
{
11 - Add the following text before the
startApp() method:
public HelloWorld2() {
}
private void initialize() {
javax.microedition.lcdui.Display.getDisplay(this).setCurrent(get_helloTextBox());
}
public void commandAction(javax.microedition.lcdui.Command command, javax.microedition.lcdui.Displayable
displayable) {
if (displayable == helloTextBox) {
if (command == exitCommand) {
javax.microedition.lcdui.Display.getDisplay(this).setCurrent(null);
destroyApp(true);
notifyDestroyed();
}
}
}
private javax.microedition.lcdui.TextBox get_helloTextBox() {
if (helloTextBox == null) {
helloTextBox = new javax.microedition.lcdui.TextBox(null, "Test String",120, 0x0);
helloTextBox.addCommand(get_exitCommand());
helloTextBox.setCommandListener(this);
}
return helloTextBox;
}
private javax.microedition.lcdui.Command get_exitCommand() {
