- \title Map Viewer (QML)
- \ingroup qtlocation-examples
-
- \brief The Map Viewer example shows how to display and interact with a map,
- search for an address, and find driving directions.
-
- \image example-mapviewer.png
-
- This is a large example covering many basic uses of maps, positioning, and
- navigation services in Qt Location. This page is divided into sections
- covering each of these areas of functionality with snippets from the code.
-
- \include examples-run.qdocinc
-
- \include example-parameters.qdocinc
-
- \section1 Overview
-
- QML types shown in this example:
-
- \list
- \li Displaying a map
- \list
- \li \l{QtLocation::Map}{Map}
- \li \l{QtLocation::MapGestureArea}{MapGestureArea}
- \li \l[QML]{Coordinate}
- \endlist
- \li Finding an address
- \list
- \li \l{QtLocation::GeocodeModel}{GeocodeModel}
- \li \l{QtLocation::MapItemView}{MapItemView}
- \li \l{QtLocation::MapCircle}{MapCircle}
- \endlist
- \li Directions and travel routes
- \list
- \li \l{QtLocation::RouteModel}{RouteModel}
- \li \l{QtLocation::MapRoute}{MapRoute}
- \endlist
- \endlist
-
- \section1 Displaying a Map
-
- Drawing a map on-screen is accomplished using the Map type, as shown
- below.
-
- \snippet mapviewer/map/MapComponent.qml top
- \snippet mapviewer/map/MapComponent.qml coord
- \snippet mapviewer/map/MapComponent.qml end
-
- In this example, we give the map an initial center \l [QML]{Coordinate}{coordinate}
- with a set latitude and longitude. We also set the initial zoom level to 50% (halfway between
- the maximum and minimum).
-
- \section1 Finding an Address (Geocoding)
-
- To locate a certain address or place on the map uses a process called
- geocoding. In order to perform a geocode operation, we first need to adjust
- our Map object to be able to receive the result.
-
- Receiving results of geocoding is done through a GeocodeModel:
-
- \snippet mapviewer/map/MapComponent.qml geocodemodel0
-
- To display the contents of the GeocodeModel we use a MapItemView:
-
- \snippet mapviewer/map/MapComponent.qml geocodeview
-
- MapItemView uses an object called a "delegate" to act as a template for the
- items it creates. This can contain any map object desired, but in this case
- we show a MapCircle:
-
- \snippet mapviewer/map/MapComponent.qml pointdel0
- \snippet mapviewer/map/MapComponent.qml pointdel1
-
- With these three objects, we have enough to receive Geocode responses and
- display them on our Map. The final piece is to send the actual Geocode
- request.
-
- To send a geocode request, first we create an \l [QML]{Address} object, and fill it
- in with the desired parameters.
-
- \snippet mapviewer/mapviewer.qml geocode0
-
- Then we set "geocodeModel.query" to the filled in \l [QML]{Address},
- and call update() on the GeocodeModel.
-
- \snippet mapviewer/map/MapComponent.qml geocode1
-
- \section1 Directions and Travel Routes
-
- Similar to the GeocodeModel, Qt Location also features the RouteModel type,
- which allows information about routes (for example driving directions) between two
- or more points, to be received and used with a Map.
-
- Here again, we instantiate the RouteModel as a property of our Map:
-
- \snippet mapviewer/map/MapComponent.qml routemodel0
-
- To display the contents of a model to the user, we need a view. Once again
- we will use a MapItemView, to display the Routes as objects on the Map:
-
- \snippet mapviewer/map/MapComponent.qml routeview0
- \snippet mapviewer/map/MapComponent.qml routeview1
-
- To act as a template for the objects we wish the view to create, we create
- a delegate component:
-
- \snippet mapviewer/map/MapComponent.qml routedelegate0
- \snippet mapviewer/map/MapComponent.qml routedelegate1
-
- With the model, view and delegate now complete, the only missing component
- is some kind of control over the model to begin the Route request process.
- In the simplest case, we can fill out a Route request using two already
- available \l [QML]{Coordinate}{coordinates}:
-
- \snippet mapviewer/mapviewer.qml routecoordinate
-
- In the next snippet, we show how to set up the request object and instruct
- the model to update. We also instruct the map to center on the start
- coordinate for our routing request.
-
- \snippet mapviewer/map/MapComponent.qml routerequest0
- \snippet mapviewer/map/MapComponent.qml routerequest1
- \snippet mapviewer/map/MapComponent.qml routerequest2
-
- This is all that is required to display a Route on the Map. However, it is
- also useful to be able to retrieve the written directions and explanation
- of the travel route. In the example, these are displayed in a \l {ListView} element.
- To create this content, we use a standard \l {Models and Views in Qt Quick#ListModel}{ListModel} and
- \l {ListView} pair. The data in the \l {Models and Views in Qt Quick#ListModel}{ListModel} is
- built from the routeModel's output:
-
- \snippet mapviewer/forms/RouteList.qml routeinfomodel0
- \snippet mapviewer/forms/RouteList.qml routeinfomodel1
- \snippet mapviewer/forms/RouteList.qml routeinfomodel3
-
- Inside the RouteModel, as you can see above, we add an
- \l{QtLocation::RouteModel::status}{onStatusChanged} handler, which
- calls the \c{showRouteList()} which updates the \c{routeInfoModel}:
-
- \snippet mapviewer/forms/RouteList.qml routeinfomodel2
