Stop map from auto centering after map render

[fourandthree]

Hi Everyone,

When I open the map panel with sencha touch the map keeps centering to my location every 2 seconds or so. Is there a way to change this? I like how it shows my location but I don't want it to keep centering itself.

Here's my code:

mapPanel = new Ext.Map({
title: 'Map',
iconCls: 'locate',
autoUpdate: false,
useCurrentLocation: true,
mapOptions: {
disableDefaultUI: true,
zoom: 6
}

});

thanks for the help!

And although I've added the autoUpdate : false to the Ext.Map params the app continues to re-centre the map. Anyone any suggestions?

in Map initComponent it appears that this is what is causing that behavior...

.. snippet from initComponent....

elseif(this.useCurrentLocation){
this.geo =this.geo || new Ext.util.GeoLocation({autoLoad:false});
            this.geo.on({
                locationupdate :this.onGeoUpdate,
                locationerror :this.onGeoError, 
                scope :this
            });
}

.. implementation of onGeoUpdate...

    onGeoUpdate :function(coords){
var center;
        if(coords){
            center =this.mapOptions.center =new google.maps.LatLng(coords.latitude, coords.longitude);
        }
        
        if(this.rendered){
            this.update(center);
        }
        else{
            this.on('activate',this.onUpdate,this,{single:true, data: center});
        }
    },

what if you were to define a GeoLocation inline that avoided the onGeoUpdate...

mapPanel = new Ext.Map({
title: 'Map',
iconCls: 'locate',
autoUpdate: false,
useCurrentLocation: true,
mapOptions: {
disableDefaultUI: true,
zoom: 6,
geo: new Ext.util.GeoLocation({autoLoad:false})
}

});

or override the onGeoUpdate function ....

You should disable

useCurrentLocation: true

in the map class. Instead have the (separate) geo-class center your map.

The useCurrentLocation: true setting overrides the autoUpdate: false.

Setting useCurrentLocation: true/false works for me. Very concise way of centering the map to current location. Thank you.

I wonder however if that config captures the current location based on network connection or GPS. I am hoping it is the latter (I have only tested it on my machine and not a mobile device yet).
