Minimal Qt5 project with QML Engine and resources

This page shows a simple Qt 5 project which uses QQmlEngine, loads Window based QML file from resources and uses a QObject based class for QML/C++ communication.

In case you have not heard about Qt or your knowledge is a bit old, the Qt White Paper is recommended for reading.

In order to have some functionality in the additional “TimeManager” class, it fetches the timezones in a Windows OS. For other OS types, you need to look further. In Qt 5.1 is expected to provide cross platform support for timezones.

The resource system Qt uses a XML file called resources.qrc that lists all the files that are compiled in the resulting binary. In this case there is only the QML file.

The TimeManager class is defined in a header file (.h) and implemented in a C++ file (.cpp).

Please note that due to the Registery dependancy, this implementation only works in Windows.
