[SOLVED] Qt Location QML : How to enable MapGestureArea ?

SylvainP

Hello
I am new to Qt Quick and I am missing something about using the Qt Quick location Map component.
I want to enable panning, flicking and pinch-to-zoom gestures but I can not found out how to do it.
The documentation gives 3 "different" examples:

http://doc.qt.io/qt-5/qml-location5-maps.html

Map {
    id: map
    // Enable pan, flick, and pinch gestures to zoom in and out
    gesture.activeGestures: MapGestureArea.PanGesture | MapGestureArea.FlickGesture | MapGestureArea.ZoomGesture
    gesture.flickDeceleration: 3000
    gesture.enabled: true
}

http://doc.qt.io/qt-5/qml-qtlocation-mapgesturearea.html

Map {
    gesture.enabled: true
    gesture.activeGestures: MapGestureArea.ZoomGesture | MapGestureArea.PanGesture
}

and
http://doc.qt.io/qt-5/qml-qtlocation-map.html

Plugin {
    id: somePlugin
    // code here to choose the plugin as necessary
}

Map {
    id: map

    plugin: somePlugin

    center {
        latitude: -27
        longitude: 153
    }
    zoomLevel: map.minimumZoomLevel

    gesture.enabled: true
}

So I wrote this code which fails to enable gesture :

main.qml:
####
import QtQuick 2.5
import QtQuick.Controls 1.4
import QtQuick.Window 2.2
import QtPositioning 5.5
import QtLocation 5.5

ApplicationWindow {
    title: qsTr("Hello World")
    width: 640
    height: 480
    visible: true

    Plugin {
        id: myPlugin
        name: "osm"
        PluginParameter { name: "osm.mapping.host"; value: "http://c.tile.thunderforest.com/outdoors/" }
    }

    Map {
        property bool followme : false
        id : map
        plugin: myPlugin
        anchors.fill: parent
        focus: true
        zoomLevel: 9
        gesture.activeGestures: MapGestureArea.PanGesture | MapGestureArea.FlickGesture | MapGestureArea.ZoomGesture
        gesture.flickDeceleration: 3000
        gesture.enabled: true
    }
}

I tested this code under android and none of panning, flicking and pinch-to-zoom gestures works.

Thank you for your help.

I misunderstood meaning of flick gesture so I missed that it was a reported bug although I did a search(for mapgesture).
https://bugreports.qt.io/browse/QTBUG-46388
It is fixed in 5.6 but not 5.5.
However there is a simple workaround. You have to add a MouseArea to the Map element as shown below :

Map {
        id : map
        plugin: myPlugin
        anchors.fill: parent
        focus: true
        zoomLevel: 9
        gesture.activeGestures: MapGestureArea.PanGesture | MapGestureArea.FlickGesture | MapGestureArea.ZoomGesture
        gesture.flickDeceleration: 3000
        gesture.enabled: true

        //XXXXXXX Added
        MouseArea {
            anchors.fill: parent
        }
        //XXXXXXX
    }

Thanks to Alexander for pointing me this.
