Component Access Rules

Presenter:Debabrata Patra, Mindfire Solutions

Ext.getCmp('ID') is used to access component globally. Don't use id in component.

Ext.ComponentQuery.query('') is used to access component globally. If we are inside a container scope. We can call container.query(). To get first element of a container. We can call container.down().
