WeatherData represents the weather - information taken from the HTTP service. It is a simple data class, but we - give it Q_PROPERTies to expose it nicely to QML, later. - - \snippet weatherinfo/appmodel.h 0 - \snippet weatherinfo/appmodel.h 1 - - AppModel models the state of the entire application. At startup, the - application first begins by waiting for network connectivity. We do - this using the QNetworkConfigurationManager and QNetworkSession family - of C++ APIs. - - \snippet weatherinfo/appmodel.cpp 0 - \snippet weatherinfo/appmodel.cpp 1 - - Once the network session is open, we proceed to get the platform's - default position source using QGeoPositionInfo::createDefaultSource() - - \snippet weatherinfo/appmodel.cpp 2 - - If no default source is available, we take a static location and fetch - weather for that. If, however, we do have a position source, we connect - its positionUpdated() signal to a slot on the AppModel and call - startUpdates(), which begins regular updates of device position. - - When a position update is received, we use the longitude and latitude - of the returned coordinate to retrieve the current "city" name for use - in the weather lookup. - - \snippet weatherinfo/appmodel.cpp 3 - - To inform the UI about this process, the cityChanged() signal is emitted - when a new city is used, and the weatherChanged() signal whenever a - weather update occurs. - - \snippet weatherinfo/appmodel.h 2 - \snippet weatherinfo/appmodel.h 3 - \snippet weatherinfo/appmodel.h 4 - - We use a QQmlListProperty for the weather forecast information, - which contains the next 4 days of forecast weather. This makes it - easy to access from QML. - - To expose these to the QML UI layer, we use the qmlRegisterType() - function. We call this once for each type we wish to register, before - loading the actual QML file. - - \snippet weatherinfo/main.cpp 0 - \snippet weatherinfo/main.cpp 1 - - Finally, in the actual QML, we instantiate the AppModel. - - \snippet weatherinfo/weatherinfo.qml 0 - \snippet weatherinfo/weatherinfo.qml 1 - \snippet weatherinfo/weatherinfo.qml 2 - - Once instantiated like this, we can use its properties elsewhere in the - QML document: - - \snippet weatherinfo/weatherinfo.qml 3 - \snippet weatherinfo/weatherinfo.qml 4 - -*/ |
