| 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.

Ext.Component.xtype.
Use this method (or its alias Ext.reg) to ... Registers a new Component constructor, keyed by a new Ext.Component.xtype. Use this method (or its alias Ext.reg) to register new subclasses of Ext.Component so that lazy instantiation may be used when specifying child Components. see Ext.Container.items Parameters:

:
voidUnregisters a component. Unregisters a component. Parameters:
| ComponentMgr | |
