QML/Get GPS data

Code snippet that draws ui and shows GPS data and accuracy, also with GPS on/off switch if one wants to conserve power.

// Made by: Ossipena

This is done with PageStack so you need main.qml that defines pagestackwindow and MainPage.qml that is loaded 
within the pagestack (here appWindow)

main.qml:

import QtQuick 1.1
import com.nokia.meego 1.0

PageStackWindow {
    id: appWindow

    MainPage {id: mainPage}


   
    ToolBarLayout {
        id: commonTools
        visible: true


        TabButton {
            text: "View trackings"
            height: parent.height
            width: 400
            onClicked: appWindow.pageStack.push(Qt.resolvedUrl("ViewPage.qml"))

        }

        ToolIcon { platformIconId: "toolbar-view-menu";
             onClicked: (myMenu.status == DialogStatus.Closed) ? myMenu.open() : myMenu.close()


        }

    }
   
}






MainPage.qml:


import QtQuick 1.1
import com.meego 1.0
import Qt 4.7
import QtMobility.location 1.1

Page {
    id: mainPage
    tools: commonTools
    //init GPS etc
    PositionSource {
        id: positionSource
        updateInterval: 1000
        //active: false
        active: gpsswitch.checked
    }
    function printableMethod(method) {
        if (method == PositionSource.SatellitePositioningMethod)
            return "Satellite";
        else if (method == PositionSource.NoPositioningMethod)
            return "Not available";
        else if (method == PositionSouce.NonSatellitePositioningMethod)
            return "Non-satellite";
        else if (method == PositionSource.AllPositioningMethods)
            return "All/multiple"
        return "source error";
