# Tutorial: The 14 Steps

This tutorial gives an introduction to GUI programming using the Qt toolkit 2.3.5 . It doesn't cover everything: The emphasis is on teaching the programming philosophy of GUI programming, and Qt's features are introduced as needed. Some commonly used features are never used in this tutorial.

Chapter one starts with a ten-line hello-world and each subsequent chapter introduces one or a few more concepts. By chapter 14, the ten lines from chapter one have turned into a 650-line game.

Tutorial chapters:

1. Hello, World!
2. Calling it Quits
3. Family Values
4. Let There Be Widgets
5. Building Blocks
6. Building Blocks Galore!
7. One Thing Leads to Another
8. Preparing for Battle
9. With Cannon You Can
10. Smooth as Silk
11. Giving It a Shot
12. Hanging in the Air the Way Bricks Don't
13. Game Over
14. Facing the Wall

This little game doesn't look much like a modern GUI application. It uses a good few of the GUI techniques, but after you've worked through it, we recommend reading the Simple Application Walkthrough too. That discusses a very simple application with all the common features (menu bars, tool bars, on-line help, printing, a couple of dialogs) in detail.
