    Default Unanswered: how to place a bubble on map using geolocation with onlocationupdatate event

    Unanswered: how to place a bubble on map using geolocation with onlocationupdatate event


    Hi friends i did a small program on placing a bubble on current location using updatelocation event but it shows only default location and also it does not place a bubble on that location.

    My code is

    first.js
    =====

    MapView = Ext.extend(Ext.Panel, {
    layout: 'card',
    initComponent: function() {
    this.map = new Ext.Map({
    useCurrentLocation: true,
    mapOptions : {
    zoom: 12,
    navigationControlOptions: {
    style: google.maps.NavigationControlStyle.SMALL
    }
    },
    geo: new Ext.util.GeoLocation({
    autoUpdate: false,
    timeout: 1000,
    listeners: {
    locationupdate: this.onLocationUpdate,
    scope: this,
    locationerror: function(geo) {
    console.log('Location update error.');
    }
    }
    })
    });

    this.items = this.map;

    MapView.superclass.initComponent.call(this);
    },


    onLocationUpdate: function(geo) {
    var position = new google.maps.LatLng(geo.latitude, geo.longitude);




    var infowindow = new google.maps.InfoWindow({
    content: 'test info text'
    });

    var marker = new google.maps.Marker({
    position: position,
    title : 'Your location!',
    map: this.map
    });
    }
    });

    It does not work properly. It does not show current location and also it doesnot place a bubble.

    Pls help me because i am new to this technology.

    And also i have one small doubt i.e

    when a person moving from one location to another location then automatically a bubble has to place at that location with the given time and also i need to draw a line among those bubbles.


    pls help me this is urgent for me.



    Thanks and Regards,
    Naseerkhan

    Map displayed with default location. It calls only locationerror event but it is not reaching locationupdate event

    thats why it shows default location.

    I have one doubt i.e how to find whether maprender event has fired or not?

    I tried so many examples which are placed in the forum but those also not working

    I tested it on emulator only but i didn't test it in mobile.

    Pls tell me the solution for this.


    Thank in advance.

    Ext.Map will fire a maprender event. You shouldn't try to add a marker or anything to the map until that is fired.
