Having trouble displaying Google Map using GMapPanel in EXTJS 4?

Ext.Loader.setPath('Ext.ux', '../ux');
Ext.require([
    'Ext.tree.*',
    'Ext.data.*',
    'Ext.window.MessageBox',
    'Ext.window.*',
    'Ext.ux.GMapPanel'
]);

var map = new Ext.ux.GMapPanel({
            xtype: 'gmappanel',
            region: 'center',
            id:  'mygooglemap',
            zoomLevel: 3,
            gmapType: 'map',
            setCenter: {
                'lat': 37.4419,
                'lng': -122.1419
            }
        });

    var layout = Ext.create('Ext.panel.Panel', {
            //renderTo: 'layout',
            width: window.innerWidth,
            height: window.innerHeight,
            //title: 'Border Layout', //no title will be blank
            layout: 'border',
            items: [{
                title: 'Message List',
                region: 'south',     // position for region
                xtype: 'panel',
                height: 100,
                split: true,         // enable resizing
                collapsible: true,
                margins: '0 5 5 5',
                collapsed: true
            },tree,map],
            renderTo: Ext.getBody() //get the body and display Layout at there
        });

Question

After successfully loading all components, including the treepanel named 'tree', the GMapPanel for the map is not displaying the Google map. Can anyone provide assistance to troubleshoot and resolve this issue? Thank you, as I am currently unable to determine the cause.

UPDATE Here is a screenshot I captured showcasing that the page should load the Google map, but it is currently blank.

Answer №1

When creating a map, it is recommended to include a marker object inside the setCenter function.

Here is an example of how you can modify your map code:

var map = new Ext.ux.GMapPanel({
        xtype: 'gmappanel',
        region: 'center',
        id:  'mygooglemap',
        zoomLevel: 3,
        gmapType: 'map',
        mapConfOpts:['enableScrollWheelZoom','enableDoubleClickZoom','enableDragging'],
        mapControls: ['GSmallMapControl','GMapTypeControl','NonExistantControl'],   
        setCenter: {
            'lat': 37.4419,
            'lng': -122.1419,
            marker:{ title: 'Palo Alto'}
        }
    });

Answer №2

Ensure that you have included the following code snippet in your index.html file:

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?v=3&sensor=false"></script>

If you have not added it yet, it would be beneficial to use a debugging browser tool to check for any errors that may not have been reported.
