ALL ITEM QUICKMAP HOW TO

To add an object programmatically, first be sure it is created with the Map as its parent (for example in an argument to Component::createObject). Map related objects can be declared within the body of a Map object in Qt Quick and will automatically appear on the Map. To perform conversions between these two, Map provides the toCoordinate and fromCoordinate functions, which are of general utility. When the map is displayed, each possible geographic coordinate that is visible will map to some pixel X and Y coordinate on the screen. See each of these properties for further details about their values. The center property contains a coordinate specifying the center of the viewport, while zoomLevel controls the scale of the map. The geographic region displayed in the Map item is referred to as its viewport, and this is defined by the properties center, and zoomLevel.

See the Plugin type for a description of how to retrieve an appropriate plugin for use.

In order to display any image in a Map item, you will need to set this property. The current Map plugin in use is contained in the plugin property of the Map item. A Map plugin consists of a data source, as well as all other details needed to display its data on-screen. There are a variety of different ways to visualize the Earth's surface in a 2-dimensional manner, but all of them involve some kind of projection: a mathematical relationship between the 3D coordinates (latitude, longitude and altitude) and 2D coordinates (X and Y in pixels) on the screen.ĭifferent sources of map data can use different projections, and from the point of view of the Map type, we treat these as one replaceable unit: the Map plugin. The Map type is used to display a map or image of the Earth, with the capability to also display interactive objects tied to the map's surface. coordinate toCoordinate(QPointF position, bool clipToViewPort).void setBearing(real bearing, coordinate coordinate).void removeMapParameter(MapParameter parameter).void removeMapItemView(MapItemView itemView).void removeMapItemGroup(MapItemGroup itemGroup).point fromCoordinate(coordinate coordinate, bool clipToViewPort).void fitViewportToGeoShape( geoShape, margins).void alignCoordinateToPoint(coordinate coordinate, QPointF point).void addMapParameter(MapParameter parameter).void addMapItemView(MapItemView itemView).void addMapItemGroup(MapItemGroup itemGroup).List of all members, including inherited members.
