Abstract

This chapter introduces some style guidelines and naming conventions that will be used in the rest of this book. The Qt Core module is introduced with examples and exercises that use Qt stream and date classes.

Qt is a modular system of classes and tools that makes it easier for you to write smaller modules of code.
It provides an almost complete replacement for STL classes/types, builds/runs on more compilers than code written using C++0x, and supports some of the same features without requiring a modern compiler.

Inside the Qt source archive, there is a collection of Examples and Demos.
Sometimes we will refer to them, and they have paths which fall under the examples/ or demos/ path prefix.
If you are using the Qt SDK or a Qt installed with Linux, you may need to run the package manager to install them.
Figure 3.1 shows the Getting Started page from the Qt Creator Welcome screen.
