Detailed Description

A QML helper item to be attached to a MapView using MapLibre.style property.

This item does not have any properties and expect to have StyleParameter implementations as children. See also SourceParameter and LayerParameter.

MapLibre.style: Style {
    id: style
 
    SourceParameter {
        id: radarSourceParam
        styleId: "radar"
        type: "image"
        property string url: "https://maplibre.org/maplibre-gl-js/docs/assets/radar1.gif"
        property var coordinates: [
            [-80.425, 46.437],
            [-71.516, 46.437],
            [-71.516, 37.936],
            [-80.425, 37.936]
        ]
    }
 
    LayerParameter {
        id: radarLayerParam
        styleId: "radar-layer"
        type: "raster"
        property string source: "radar"
 
        paint: {
            "raster-opacity": 0.9
        }
    }
}

Parameters can also be manipulated programatically using addParameter, removeParameter and clearParameters functions.

let layerParam = Qt.createQmlObject(`
    import MapLibre 3.0
 
    LayerParameter {
        styleId: "tileLayer"
        type: "raster"
        property string source: "tileSource"
    }
    `,
    style,
    "layerParamSnippet")
style.addParameter(layerParam)
