ExtJS Google Map SetCenter ERROR - google-maps

Question

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,{
xtype: 'gmappanel',
region: 'center',
id : 'mygooglemap',
center: new google.maps.LatLng(3.951941, 102.052002),
mapOptions: {
zoom: 7,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
}],
renderTo: Ext.getBody() //get the body and display Layout at there
});
});
function addInfoWindow(lat,lng) {
var map123 = Ext.getCmp('mygooglemap');
var latLng = new google.maps.LatLng(lat, lng);
map123.SetCenter(latLng);
}
how come i can't set the map to center of the coordinate?
Firebug with this error
TypeError: map123.setCenter is not a function
[Break On This Error]
map123.setCenter(latLng);
EDITED
where is my GMapPanel.js download from https://raw.github.com/VinylFox/ExtJS.ux.GMapPanel/master/src/GMapPanel3.js
then i put it in my localhost/ux/GMapPanel3.js
and this is my config before use the GMapPanel
Ext.Loader.setPath('Ext.ux', 'ux/');
Ext.require([
'Ext.tree.*',
'Ext.data.*',
'Ext.window.MessageBox',
'Ext.window.*',
'Ext.ux.GMapPanel'
]);
but fail to set Center , why?

I am assuming that you are using the plugin from here: https://github.com/VinylFox/ExtJS.ux.GMapPanel
Assuming that is true, from looking at the code it looks like you need to use getMap() on your gmappanel before calling setCenter():
map123.getMap().setCenter(latLng);
Or, you can specify the setCenter property when configuring the gmappanel:
{
xtype: 'gmappanel',
region: 'center',
id : 'mygooglemap',
setCenter: {
lat: 3.951941,
long: 102.052002
},
mapOptions: {
zoom: 7,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
}
One of the great things about ExtJS/Javascript is that you have access to the code of all of your libraries. When you see errors like "xxx is not a function", it should be pretty self-explanatory: the function you are trying to use is not available on the object on which you are calling it.
