Qt 5 Blueprints

Book Description

Design, build, and deploy cross-platform GUI projects using the amazingly powerful Qt 5 framework

In Detail

Qt is a cross-platform application development framework that provides great visual interfaces for users and intuitive APIs for developers. The current version, Qt 5, provides enormous modules, from threading to interface animations, to ease your pain when developing cross-platform applications.

Starting with the basic concepts and fundamentals of Qt 5, Qt 5 Blueprints helps you get familiarized with the layouts and widgets of Qt as you build and debug a test application in Qt Creator. You will pick up the Qt design philosophy throughout the book, which will definitely help you to script your code in a more elegant manner.

What You Will Learn

  • Create graphical user interface applications with a customized layout and widgets

  • Explore how the Model-View-Controller architecture works and relevant classes in Qt

  • Develop a configurable application that is able to save and restore its own settings

  • Write both static and dynamic plugins for Qt Widgets and Qt Quick applications

  • Convert your single-threaded application to a nonblocking application by moving part of the application to another thread

  • Enable your applications to support other languages dynamically
