Description
Hi
I'm using mapboxgl in Qt QML application (5.10.1), I have app based on this example:
https://github.com/tmpsantos/qmapboxglapp/tree/tmpsantos-cheapruler
There is layer with 3D buildings
MapParameter {
type: "layer"
property var name: "3d-buildings"
property var source: "composite"
property var sourceLayer: "building"
property var layerType: "fill-extrusion"
property var minzoom: mapPage.buildingZoom
}
MapParameter {
type: "filter"
property var layer: "3d-buildings"
property var filter: [ "==", "extrude", "true" ]
}
MapParameter {
type: "paint"
property var layer: "3d-buildings"
property var fillExtrusionColor: "#00617f"
property var fillExtrusionOpacity: .6
property var fillExtrusionHeight: { return { type: "identity", property: "height" } }
property var fillExtrusionBase: { return { type: "identity", property: "min_height" } }
}
I have bound minzoom to mapPage.buildingZoom property so I thought I could change this layer visibility but when I change mapPage.buildingZoom property app is crashing with an error:
terminate called after throwing an instance of 'std::runtime_error' what(): Layer 3d-buildings already exists
Best Regards
