Overview of this book

Qt is a powerful development framework that serves as a complete toolset for building cross-platform applications, helping you reduce development time and improve productivity. Completely revised and updated to cover C++17 and the latest developments in Qt 5.12, this comprehensive guide is the third edition of Application Development with Qt Creator. You'll start by designing a user interface using Qt Designer and learn how to instantiate custom messages, forms, and dialogues. You'll then understand Qt's support for multithreading, a key tool for making applications responsive, and the use of Qt's Model-View-Controller (MVC) to display data and content. As you advance, you'll learn to draw images on screen using Graphics View Framework and create custom widgets that interoperate with Qt Widgets. This Qt programming book takes you through Qt Creator's latest features, such as Qt Quick Controls 2, enhanced CMake support, a new graphical editor for SCXML, and a model editor. You'll even work with multimedia and sensors using Qt Quick, and finally develop applications for mobile, IoT, and embedded devices using Qt Creator. By the end of this Qt book, you'll be able to create your own cross-platform applications from scratch using Qt Creator and the C++ programming language.

Placing a position marker on a Map View

Since version 5.0, Qt provides us with a Map View component that displays a map or image of the Earth, similar to Google Maps. Due to licensing issues, Qt Map View doesn't support Google Maps. The default tiled map service provider for Qt Map View is the community mapping project OpenStreetMap (OSM) since it is free of charge. Other than OSM, you can use other commercial service providers such as Mapbox, ArcGIS, and HERE.

Unlike other third-party mapping solutions, Qt Map View renders the tiled map using a native rendering engine (powered by Qt Quick) instead of embedding a web view onto the app. Native rendering speeds up performance and keeps your app size small since it doesn't include all the unnecessary resources needed by the web view. However, you can't interact with the Map View using C++ at the moment, only QML. I...
