Installing Qt Mobility 1.1.0 in Windows Vista | Qt Quick | Tutorials

With the release of Qt 4.7.1 and Qt Mobility 1.1.0, both in 9th Nov 2010, their support for QML has greatly improved. This modest guide will assume that none of these tools are installed in the current system.

The following four items are to be installed:

Once the three first items have been installed, open the Qt 4.7.1 Command Prompt, which should be available via start menu, and change the current directory to Qt Mobility source location.

Start off by running the configuration, you may change the prefix, which in this case assumes that Qt was installed in C:\Qt\4.7.1 directory.

configure.bat -prefix=C:\Qt\Mobility -release

Next step would be to initiate the compile process:

mingw32-make

Installation:

mingw32-make install

Finally add the library directory to the PATH variable. In this example it would have been C:\Qt\Mobility\lib. This can be done via Control Panel -> System -> Advanced System Settings -> Advanced tab -> Environment Variables. Edit the PATH variable by adding the above library path to the end, separate from previous values with ; .

The Qt Mobility API with QML bindings is filled with opportunities, while the following example merely tests the successful installation.

You should be able to see in the C:\Qt\4.7.1\imports directory few additional folders, each named according to the API parent, such as QtMobility and QtMultimediaKit.

import QtQuick 1.0
import QtMobility.location 1.1

/**
 * Map with a simple interaction to change its center
 * http://apidocs.meego.com/git-tip/qtmobility/qml-map.html
 */
Rectangle {
    width: 800
    height: 600

    Map {
        id: mapArea
        anchors.fill: parent

        // http://en.wikipedia.org/wiki/Ut%C3%B6,_Finland
        center.latitude: 59.783333
        center.longitude: 21.366667

        connectivityMode: Map.OnlineMode
        mapType: Map.TerrainMap
        size.width: parent.width
        size.height: parent.height
        zoomLevel: 14

        // No idea where to find a list of possible plugins...
        plugin : Plugin {
            name : "nokia"
        }

        MapCircle {
            border.color: "pink"
            border.width: 2
            center: mapArea.center
            radius: 1000 // 1 km
        }
    }

    // Change map center to where it was clicked
    MouseArea {
        anchors.fill: parent
        onClicked: {
            var pos = mapArea.toCoordinate(
                    Qt.point(mouse.x, mouse.y));
            console.log("alt: " + pos.altitude +
                        ", lat: " + pos.latitude +
                        ", lng: " + pos.longitude);
            mapArea.center = pos;
        }
    }
}

Seems actually that the Map element is not "officially" in the release 1.1.0 but in 1.2.0, at least while looking at the documentation version.

Additionally it might be interesting to browse through the bugs for the API. Please post there if you encounter any problems or errors.
