Preface

Whether you're just getting started with programming or you've settled on Qt as the GUI toolkit for your project, Qt Creator is a great choice for an Integrated Development Environment (IDE). In this book, we work to help you make the most of Qt and Qt Creator, showing you almost every facet of using Qt Creator, from its configuration through compiling and debugging applications along with numerous tips and tricks. Along the way, you gain valuable experience not just with Qt Creator as an IDE, but with Qt and Qt Quick as well. After reading this book, you'll be able to:

Edit, compile, debug, and run C++ applications using Qt Creator, opening a path to build state-of-the-art console and GUI applications with Qt and with the Standard Template Library (STL)
Edit, compile, debug, and run Qt Quick applications using Qt Creator, giving you access to one of the most advanced declarative GUI authoring environments anywhere
Design GUI applications using Qt Designer to build either traditional widget-based or Qt Quick applications
Analyze the memory and the runtime performance of your Qt applications, make improvements, and fix defects
Provide localized versions of your application so that you can deploy it all over the world in different languages
Use Qt Quick and Qt Widgets to write mobile applications for platforms such as Google Android
Build multimedia- and sensor-aware applications with Qt's support for multimedia and sensors
