Learn Qt 5

Overview of this book

Qt is a mature and powerful framework for delivering sophisticated applications across a multitude of platforms. It has a rich history in the Linux world, is widely used in embedded devices, and has made great strides in the Mobile arena over the past few years. However, in the Microsoft Windows and Apple Mac OS X worlds, the dominance of C#/.NET and Objective-C/Cocoa means that Qt is often overlooked. This book demonstrates the power and flexibility of the Qt framework for desktop application development and shows how you can write your application once and deploy it to multiple operating systems. Build a complete real-world line of business (LOB) solution from scratch, with distinct C++ library, QML user interface, and QtTest-driven unit-test projects. This is a suite of essential techniques that cover the core requirements for most LOB applications and will empower you to progress from a blank page to shipped application.

The default Qt approach

When we created our cm-tests project, Qt Creator helpfully created a ClientTests class for us to use a starting point, containing a single test named testCase1. Let's dive straight in and execute this default test and see what happens. We'll then take a look at the code and discuss what's going on.

Switch the Run output to cm-tests, and compile and run:

You won’t see any fancy applications spring to life this time, but you will see some text in the Application Output pane in Qt Creator:

********* Start testing of ClientTests *********
Config: Using QtTest library 5.10.0, Qt 5.10.0 (i386-little_endian-ilp32 shared (dynamic) debug build; by GCC 5.3.0)

Totals: 3 passed, 0 failed, 0 skipped, 0 blacklisted, 0ms
