Ext.AbstractManagerExt.ComponentManager
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.
Creates a new Component from the specified config object using the config object's xtype to determine the class to instantiate.
A configuration object for the Component you wish to create.
The constructor to provide the default Component type if
the config object does not contain a xtype. (Optional if the config contains a xtype).
The newly instantiated Component.
Executes the specified function once for each item in the collection. Returning false from the function will cease iteration.
The paramaters passed to the function are:
The key of the item
The value of the item
The total number of items in the collection
The function to execute.
The scope to execute in. Defaults to this.
Returns an item by id. For additional details see Ext.util.HashMap.get.
Returns an item by id. For additional details see Ext.util.HashMap.get.
The id of the item
The item, undefined if not found.
Gets the number of items in the collection.
Gets the number of items in the collection.
The number of items in the collection.
Checks if an item type is registered.
Checks if an item type is registered.
The mnemonic string by which the class may be looked up
Whether the type is registered.
Registers a function that will be called when an item with the specified id is added to the manager. This will happen on instantiation.
The item id
The callback function. Called with a single parameter, the item.
The scope (this reference) in which the callback is executed. Defaults to the item.
Registers an item to be managed
Registers an item to be managed
The item to register
Registers a new item constructor, keyed by a type key.
Registers a new item constructor, keyed by a type key.
The mnemonic string by which the class may be looked up.
The new instance class.
