Hi All,

I know that there are thousand of posts about this,but I want to know is there any way to when application exit from anywhere,I mean no mather what is current screen when end call button is presing I want to exit application.Or I must provide onClose function to every screen?

System.exit(0)

...will exit from anywhere in the applicaiton.

I know.I just don't want to write onClose,keyDown or keyChar code for each screen.

I asked if there any general way to put some code  and don't bother about writing any more code elsewere.

MainScreen will anatomically close the application if you close the last screen in the DisplayStack. 

So if you start with one MainScreen and then push another MainScreen , then closing that second MainScreen will correctly display the first MainScreen underneath,  But closing the first MainScreen will exit the app.

Alternatively, start on the first MainScreen , when you push the second MainScreen , if you also pop the first MainScreen, the closing the second one will close the app.

That said, I think this is bad practice,  I recommend you create a general exit point for your application and make sure it always goes through this.  That way it can tidy up any resources that it needs to.

Thanks Peter, I did the following in each main screen I overrides the keydown event and in it I check if the end call button is pressed then I call my custom function which will pop screens until the first one and after that exit application.However I don't like this approach.
