Capturing mouse movement over a MapView

Anonymous User — Fri, 12 Oct 2018 08:22:43 GMT

Is there any way to capture the mouse movement over a MapView?

The mousePositionChanged signal documentation is slightly mis-leading, because it only fires when the mouse button is held down while the mouse is moved. I'm looking for a signal similar to the onPositionChanged signal of a MouseArea.

I tried placing a MouseArea over my mapview, but then nothing propagates through to the MapView, i.e. can't pan or click (although mouse wheel zooming seems to work!?). I tried manually triggering all the MapView mouse signals (e.g. whenever the mouse area pressed signal fires I called mapView.mousePressed(mouse) etc) but still couldn't pan/move the map around.

So I guess I'm asking for either of two things:

1) a way to capture the mouse hover movement over a MapView so I don't have to use a MouseArea at all (my preference)

2) a way to place a MouseArea over a MapView to capture the mouse hover movement but still be able to navigate the map underneath.

mousePositionChanged(MouseEvent mouse)

Emitted when the mouse is moved over the GeoView.

Looping in ArcGIS Runtime SDK for Qt‌ to see if people in that group have an explanation to the mis-leading documentation and explanation on the mouse event.

Looks like we need to add some clarification to our doc. You can accomplish this with a MouseArea and accepting the mouse events to let everything propagate through.

MapView {
    id: mapView
    anchors.fill: parent
    // add a map to the mapview
    Map {
        // add the BasemapTopographic basemap to the map
        BasemapTopographic {}
    }        

    MouseArea {
        id: mouseArea
        anchors.fill: parent
        hoverEnabled: true
        onMouseXChanged: {
            console.log(mouse.x, mouse.y)
        }
        onPressed: mouse.accepted = false
    }
