Getting Values from Config

[jarobi]

Is there another way to get the Values. For example:

A Panel includes 2 Fieldset and each Fieldset has a textarea and displyafield

Panel (id:'panel')
....fieldset ( id :'fieldset1')
........textarea1 (id:'txt1')
.......displayfield1(id: 'd1')
...fieldset ( id :'fieldset2')
.......textarea2 (id:'txt2')
......displayfield2 (id: 'd2')

Ext.getCmp('panel').items.items[0].items.items[0]

So im getting "textarea1". But i dont want use Indexes and i dont want go directly to the element( Ext.getCmp(txt1)), im searching something like this:
Ext.getCmp('panel').items.items.get('textarea1').items.items.get('txt1')

Use the component query:
- http://docs.sencha.com/ext-js/4-0/#!...ComponentQuery

Using getCmp() is not recommended for production code (as it relies on DOM IDs), and "items.items.items[0]" is (1) ugly and (2) unreliable.

Every component has methods like child(), down() etc. that use the ComponentQuery.
