详细描述

MapItemView is used to populate Map with MapItems from a model. The MapItemView type only makes sense when contained in a Map, meaning that it has no standalone presentation.

用法范例

This example demonstrates how to use the MapViewItem object to display a route 在 map :

import QtQuick 2.0
import QtPositioning 5.5
import QtLocation 5.6
Map {
    RouteModel {
        id: routeModel
    }
    MapItemView {
        model: routeModel
        delegate: routeDelegate
    }
    Component {
        id: routeDelegate
        MapRoute {
            route: routeData
            line.color: "blue"
            line.width: 5
            smooth: true
            opacity: 0.8
        }
    }
}
					

特性文档编制

autoFitViewport : 组件

This property controls whether to automatically pan and zoom the viewport to display all map items when items are added or removed.

Defaults to false.

delegate : 组件

This property holds the delegate which defines how each item in the model should be displayed. The Component must contain exactly one MapItem -derived object as the root object.

model : model

This property holds the model that provides data used for creating the map items defined by the delegate. Only QAbstractItemModel based models are supported.
