QNX CAR 2.1 includes the runtime binaries for version 5.2 of the Qt framework as well as several Qt-compliant libraries that allow HMI apps to access middleware services.
Developers can write apps that use the Qt framework to specify their GUIs and use the Qt-compliant libraries to access many middleware services. These services include but aren't limited to:
As Figure 1 illustrates, Qt apps access middleware services through Qt5 interfaces in their source files. These interfaces are exposed by Qt libraries and consist of C++ classes that manage services such as media, navigation, radio, and phone. Each app links in its own copy of any required Qt libraries, which talk directly to middleware services (e.g., mm-player, QDB) through their C APIs or PPS. The platform ships with these Qt-compliant libraries:
You can find full details on these libraries in the Qt Development Environment guide.
