Class Ext.ComponentMgr

Package:Ext
Defined In:ComponentMgr.js
Class:ComponentMgr
Extends:Object

Provides a registry of all Components (instances of Ext.Component or any subclass thereof) on a page so that they can be easily accessed by component id (see get, or the convenience method Ext.getCmp).

This object also provides a registry of available Component classes indexed by a mnemonic code known as the Component's xtype. The xtype provides a way to avoid instantiating child Components when creating a full, nested config object for a complete Ext page.

A child Component may be specified simply as a config object as long as the correct xtype is specified so that if and when the Component needs rendering, the correct type can be looked up for lazy instantiation.

For a list of all available xtypes, see Ext.Component.



This class is a singleton and cannot be created directly.
