QML Element MapMouseArea in QtMobility

[ssa21]

Hi:

I am trying to add a MapMouseArea on the QML Map element. However, I am getting an error that

"MapMouseArea is not a type"

Here is my code

@
import QtQuick 1.0
import Qt 4.7
import QtMobility.location 1.2

Rectangle {
id: test
width: 800
height: 400
Text {
text: "test"
anchors.centerIn: parent
}

PositionSource {
            id: positionSource
            updateInterval: 1000
            active: true
            // nmeaSource: "nmealog.txt"
    }

Rectangle {
    id: mapWindow
    x: 21
    y: 18
    width: 425
    height:  360
    color: "#80ff0000"
    Text {
        text:  "Map Window"
        anchors.baselineOffset:  10
    }

    Map {
        id: map
        z : 1
        plugin : Plugin {
                            name : "nokia"
                        }
        size.width: parent.width
        size.height: parent.height
        zoomLevel: 7
        center: Coordinate {
            latitude: 43.9
            longitude: -79.45
        }

        MapText { text: "Hello"; font.capitalization: Font.AllLowercase }

        MapMouseArea {
            property int lastX : -1
            property int lastY : -1

            onPressed : {
                lastX = mouse.x
                lastY = mouse.y
            }
            onReleased : {
                lastX = -1
                lastY = -1
            }
            onPositionChanged: {
                if (mouse.button == Qt.LeftButton) {
                    if ((lastX != -1) && (lastY != -1)) {
                        var dx = mouse.x - lastX
                        var dy = mouse.y - lastY
                        map.pan(-dx, -dy)
                    }
                    lastX = mouse.x
                    lastY = mouse.y
                }
            }
            onDoubleClicked: {
                map.center = mouse.coordinate
                map.zoomLevel += 1
                lastX = -1
                lastY = -1
            }
        }
    }

    Keys.onPressed: {
        if (event.key == Qt.Key_Plus) {
            map.zoomLevel += 1
        } else if (event.key == Qt.Key_Minus) {
            map.zoomLevel -= 1
        } else if (event.key == Qt.Key_T) {
            if (map.mapType == Map.StreetMap) {
                map.mapType = Map.SatelliteMapDay
            } else if (map.mapType == Map.SatelliteMapDay) {
                map.mapType = Map.StreetMap
            }
        }
    }

}

}

From the doc:
@A MapMouseArea is an invisible item that is typically used in conjunction with a visible map object or map item in order to provide mouse handling.@

I think that the this would actually work better for you:
@
MouseArea {
anchors.fill: map
property int lastX : -1
property int lastY : -1

            onPressed : {
                lastX = mouse.x
                lastY = mouse.y
            }
            onReleased : {
                lastX = -1
                lastY = -1
            }
            onPositionChanged: {
                if (mouse.button == Qt.LeftButton) {
                    if ((lastX != -1) && (lastY != -1)) {
                        var dx = mouse.x - lastX
                        var dy = mouse.y - lastY
                        map.pan(-dx, -dy)
                    }
                    lastX = mouse.x
                    lastY = mouse.y
                }
            }
            onDoubleClicked: {
                map.center = mouse.coordinate
                map.zoomLevel += 1
                lastX = -1
                lastY = -1
            }
        }

Thanks kkrzewniak:

That seemed to work with minor changes. I realized that the main reason original code was not working was because I was running the code on Fremantle emulator. Recreating the project as a Haramattan project seemed to do the trick.

Thanks again for your help...
