In this tutorial, I will show you how to quickly manage screens using the RIM UI API. The BlackBerry OS maintains a stack of screens, and your app can be pushed and popped from this stack. These are normal screen display operations. You can even hide your screen from the display, and it will show the BlackBerry home screen. You can close the screen as well.

This tutorial will simply walk you through the various layout managers available to you using RIM’s UI API (not MIDP). RIM’s layout managers are akin to Swing layout managers, and allow you to arrange lots of fields (aka components in Swing), on the screen. You can create your own layout managers, just like in Swing, but this tutorial will show you how to use the built in ones. If none of the layout managers shown here work for you, then you can composite layout managers to get the desired look for your app, before creating your own.

This tutorial will simply walk you through creating your first GUI app using RIM’s UI API (not MIDP). Only a skeleton will be created, that you can later expand on to create your own projects.
