    Default Answered: How do I set the center coordinates of a map?

    {
    xtype: 'map',
    flex: 1,
    mapOptions: {
    zoomControl: false,
    panControl: false,
    rotateControl: false,
    streetViewControl: false,
    mapTypeControl: false,
    zoom: 13
    }
    }

    Hi all,

    I got a map to show up in the container that I want, but I don't know how to show the map that I want. I don't mind just hard coding the coordinating... but later on, ideally use coordinates from a model.

    Let's assume, Lat and Long are X and Y. How would I tell the map or mapOptions what location I want it to show me?

    I have tried a few things, including:

    1. Adding center to mapOptions..
    center : new google.maps.LatLng(X, Y)

    2. Adding 'LatLng' or 'latitute' and 'longitude' attibutes to map and mapOptions... but im just "hoping it works" rather than have a specific strategy with it.

    Help!

    Thanks!

    Amrit

    This works for me:

    Code:
    new Ext.Map({
    fullscreen : true,
    mapOptions : {
        zoomControl       : false,
        panControl        : false,
        rotateControl     : false,
        streetViewControl : false,
        mapTypeControl    : false,
        zoom              : 13,
        center            : new google.maps.LatLng(38.62452, -90.18514)
    }
});
    YOu have to be careful of using namespaces in properties like config objects as the Google API must be loaded before that class is defined.

    This will center the map on Apple Computer, Inc. headquarters and also drop a pin with a title that will show on hover.

    app.js
    Code:
    Ext.application({
    name: 'test',


    views: ['Locations'],


    launch: function() {
        Ext.create('test.view.Locations');
    }
});
    Locations.js

    Code:
    Ext.define('test.view.Locations', {
    extend: 'Ext.Panel',


    config:  {
        layout: 'fit',
        fullscreen: true,


        items: [
            {
                xtype: 'map',
                mapOptions: {
                    center: new google.maps.LatLng(37.332495,-122.03056),
                    zoom: 16,
                    mapTypeId: google.maps.MapTypeId.ROADMAP,
                    navigationControl: true,
                    navigationControlOptions: {
                        style: google.maps.NavigationControlStyle.DEFAULT
                    }
                },


                listeners: {
                    maprender: function(extMapComonent, googleMapComponent) {
                        var marker = new google.maps.Marker({
                            position: new google.maps.LatLng(37.332495,-122.03056),
                            title: 'Apple Computer, Inc.',
                            map: googleMapComponent,
                            animation: google.maps.Animation.DROP,
                        });
                    }
                }
            }
        ]
    }
});
    In HTML file's <head> section:
    Code:
    <script src="http://maps.google.com/maps/api/js?sensor=true" type="text/javascript"></script>
