Question about Alerttypes (code included)

Question

Hi,
I have this code where I'm comparing two dates, if its outdated then the program will exit. That works perfectly. But when the program is outdated a screen is supposed to be shown to the user and prompt a text. I can only get this screen to show very very quick, what I'd really want is for this screen to be shown and have the user press like "OK" or any key for that matter to exit the program, just to make sure they actually get a chance to read it. I thought my code (shown below) would do that, but apparently it doesnt .. so .. please help me with an advice on how to fix it =)
     if (todayNum > endDate) {
          Alert alert = new Alert("Demo version outdated", "This demoversion is outdated. Please request a new version.", null, AlertType.CONFIRMATION);
          Display.getDisplay(this).setCurrent(alert);
     // Program done, exit now
          destroyApp(true);
          notifyDestroyed();
     }

Answer 1

I meant a custom CommandListener, not alert, i hope that doesnt confuse things
quick example, without checking the API (but to give an idea of what i mean) would be something like:
Alert endAlert = new Alert("Demo version outdated", "This demoversion is outdated. Please request a new version.", null, AlertType.CONFIRMATION);
endAlert.addCommand(new Command("ok", Command.OK, 1));
endAlert.setCommandListner(new CommandListener() {
public void commandAction(Command c, Displayable d) {
destroyApp(true);
notifyDestroyed();
Display.getDisplay(this).setCurrent(alert);
