Welcome back to the second Xlib tutorial. This time we will make our little program behave much more like a real application. We will learn how to handle events from the X server in order to process user input and resizing of our window. We will also set the title property of the window and how to handle errors.

Have you ever wondered what is going on behind the scenes of X11 windowmanageres and toolkits? Here is a chance to get into native X programming with Xlib.

Qt already comes with an asynchronous system called events, however it is more or less bound to a set number of message types. In larger GUI applications one might be interested in something which scales better. I'll explain one such method.

All the major game developers do it, why can't you? Using OpenGL is not simple, but it's not impossible either. (Some experience in C++ and/or Qt may be required to follow this article.)

The headlines from zez.org is now available in RSS format.

The Document Object Model (DOM) by the World Wide Web Consortium specifies a simple way of interacting with various document formats, including XML. Trolltech's Qt implements some very handy DOM classes. In this tutorial I'll demonstrate the basic principles of DOM, and give some pointers on how to use the Qt DOM classes.

In the third and final issue we'll dig into the details regarding naming conventions, functions, name spaces, classes, comments and exceptions.

Coding standards define a standard for the look and feel of your code. This is helpful to most projects, and to some it is a necessity. Especially in open source projects. In this second issue I'll show eZ system's standards regarding macros, indentation and brackets.

The Qt class QCanvas features optimized 2D graphics with game related functions, such as sprites and collision detection. This article describes how to use this in a small game.
