View Full Version : When to use config: ? (layout not working)

6 Nov 2013, 7:21 AM
I have seen config: used here and there, and decided to start using it to see what it actually does. I thought it was just to separate new properties and existing properties within a Ext.define, however certain things seem to get messed up when I use it like that. Here is an example:

Ext.define('appName.view.vViewport', {
extend: 'Ext.container.Viewport',

config: {
layout: 'border',
items: [
region: 'center',
xtype: 'panel'
region: 'south',
xtype: 'panel'

initComponent: function () {
var me = this;


with layout inside the config, it appears to use auto (not border), with layout outside the config it works as expected. Can someone give me a brief explanation of config: or at least point me to detailed documentation on it's use. Thanks.

It is most used in Touch, not ExtJS.
However, for my opinion, it is rather limited, because it doesn't allow to override not "configurable" properties and/or methods.
