However, it can't be - specified manually. - - \note Free plans are used for both providers, which implies certain - limitations on the amount of weather requests. If the limits are exceeded, - the providers become temporary unavailable. When both providers are - unavailable, the application would not be able to show any weather - information. In this case it is required to wait until at least one of the - providers becomes available again. - - \section1 Application Data Models - - The key part of this example is the application's data model, contained - in the \c WeatherData and \c AppModel classes. \c WeatherData represents - the weather information taken from the HTTP service. It is a simple data - class, but we use \l Q_PROPERTY to expose it nicely to QML later. - It also uses \l QML_ANONYMOUS macro, which makes it recognized in QML. - - \snippet weatherinfo/appmodel.h 0 - \snippet weatherinfo/appmodel.h 1 - - \c AppModel models the state of the entire application. At startup, we - get the platform's default position source using - \l QGeoPositionInfoSource::createDefaultSource(). - - \snippet weatherinfo/appmodel.cpp 0 - \snippet weatherinfo/appmodel.cpp 1 - - If no default source is available, we take a static position and fetch - weather for that. If, however, we do have a position source, we connect - its \l {QGeoPositionInfoSource::}{positionUpdated()} signal to a slot on the - \c AppModel and call \l {QGeoPositionInfoSource::}{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 weather data for the specified - location. - - \snippet weatherinfo/appmodel.cpp 2 - - To inform the UI about this process, the \c cityChanged() signal is emitted - when a new city is used, and the \c weatherChanged() signal whenever a - weather update occurs. - - The model also uses \l QML_ELEMENT macro, which makes it available in QML. - - \snippet weatherinfo/appmodel.h 2 - \snippet weatherinfo/appmodel.h 3 - \snippet weatherinfo/appmodel.h 4 - - We use a \l QQmlListProperty for the weather forecast information, - which contains the weather forecast for the next days (the number of days - is provider-specific). This makes it easy to access the forecast from QML. - - \section1 Expose Custom Models to QML - - To expose the models to the QML UI layer, we use the \l QML_ELEMENT and - \l QML_ANONYMOUS macros. See the \l QQmlEngine class description for more - details on these macros. - - To make the types available in QML, we need to update our build accordingly. - - \section2 CMake Build - - For a CMake-based build, we need to add the following to the - \c {CMakeLists.txt}: - - \quotefromfile weatherinfo/CMakeLists.txt - \skipto qt_add_qml_module(weatherinfo - \printuntil ) - - \section2 qmake Build - - For a qmake build, we need to modify the \c {weatherinfo.pro} file in the - following way: - - \quotefromfile weatherinfo/weatherinfo.pro - \skipto CONFIG - \printuntil QML_IMPORT_MAJOR_VERSION - - \section1 Instantiate the Models in QML - - Finally, in the actual QML, we instantiate the \c {AppModel}: - - \snippet weatherinfo/weatherinfo.qml 0 - \snippet weatherinfo/weatherinfo.qml 1 - \snippet weatherinfo/weatherinfo.qml 2 - - Once the model is instantiated like this, we can use its properties - elsewhere in the QML document: - - \snippet weatherinfo/weatherinfo.qml 3 - \snippet weatherinfo/weatherinfo.qml 4 - - \section1 Files and Attributions - - The example bundles the following images from Third-Party sources: - - \table - \row - \li \l{weatherinfo-tango-icons}{Tango Icons} - \li Public Domain - \row - \li \l{weatherinfo-tango-weather-pack}{Tango Weather Icon Pack by Darkobra} - \li Public Domain - \endtable -*/ diff --git a/examples/positioning/weatherinfo/icons/README.txt b/examples/positioning/weatherinfo/icons/README.txt deleted file mode 100644 index d3841532..00000000 --- a/examples/positioning/weatherinfo/icons/README.txt +++ /dev/null @@ -1,5 +0,0 @@ -The scalable icons are from: - -http://tango.freedesktop.org/Tango_Icon_Library -http://darkobra.deviantart.com/art/Tango-Weather-Icon-Pack-98024429 - diff --git a/examples/positioning/weatherinfo/icons/qt_attribution.json b/examples/positioning/weatherinfo/icons/qt_attribution.json deleted file mode 100644 index 23bbe386..00000000 --- a/examples/positioning/weatherinfo/icons/qt_attribution.json +++ /dev/null @@ -1,28 +0,0 @@ -[ - { - "Id": "weatherinfo-tango-weather-pack", - "Name": "Tango Weather Icon Pack by Darkobra", - "QDocModule": "qtpositioning", - "QtUsage": "Used in the \"Weather Info (C++/QML)\" example", - "QtParts": [ "examples" ], - "Description": "74 brand spankin' new Tango icons for your viewing pleasure.", - "Homepage": "https://www.deviantart.com/darkobra/art/Tango-Weather-Icon-Pack-98024429", - - "License": "Public Domain", - "Copyright": "Copyright DarKobra (C Stark)", - "Files": "weather-fog.png weather-haze.png weather-icy.png weather-sleet.png weather-sunny.png weather-sunny-very-few-clouds.png weather-sunny-few-clouds.png weather-thunder-shower.png" - }, - { - "Id": "weatherinfo-tango-icons", - "Name": "Tango Icons", - "QDocModule": "qtpositioning", - "QtUsage": "Used in the \"Weather Info (C++/QML)\" example", - "QtParts": [ "examples" ], - "Description": "The Tango Desktop Project exists to help create a consistent graphical user interface experience for free and Open Source software.
