Class Ext.ComponentMgr

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

Provides a common registry of all components (specifically subclasses of Ext.Component) on a page so that they can be easily accessed by component id (see Ext.getCmp).

Every component class also gets registered in ComponentMgr by its 'xtype' property, which is its Ext-specific type name (e.g., Ext.form.TextField's xtype is 'textfield'). This allows you to check the xtype of specific object instances (see Ext.Component.getXType and Ext.Component.isXType). For a list of all available xtypes, see Ext.Component.



This class is a singleton and cannot be created directly.
