Navigate the Blackberry screen stack

You need sometimes to know which screens are in the screens stack of your Blackberry application maybe because you want to remove all the screen below a specific screen because they are not needed anymore.

First of all you can get the active screen using the instruction:

UiApplication.getUiApplication.getActiveScreen();

Once you have the screen object you can call on it the method:

getScreenBelow()

you will get the screen object below. Generally you can move along the stack using also the method

getScreenAbove()

used together with the previous getScreenBelow method.
