## Constructor Details

### NestedLayoutPanel

`public function NestedLayoutPanel(`Ext.BorderLayout layout`, `String/Object config`)`
Create a new NestedLayoutPanel.
Parameters:

- `layout` : Ext.BorderLayout
  The layout for this panel
- `config` : String/Object
  A string to set only the title or a config object

## Method Details

### addEvents

`public function addEvents(`Object object`)`
Copies any events from the passed object onto this object if they do not already exist. The passed object must also inherit from Observable for this method to have any effect.
Parameters:

- `object` : Object
  The object from which to copy events

Returns:

- `void`

This method is defined by Observable.

### addListener

`public function addListener(`String eventName`, `Function handler`, [`Object scope`], [`Object options`])`
Appends an event handler to this component
Parameters:

- `eventName` : String
  The type of event to listen for
- `handler` : Function
  The method the event invokes
- `scope` : Object
  (optional) The scope in which to execute the handler function. The handler function's "this" context.
- `options` : Object
  (optional) An object containing handler configuration properties. This may contain any of the following properties:
  - scope {Object} The scope in which to execute the handler function. The handler function's "this" context.
  - delegate {String} A simple selector to filter the target or look for a descendant of the target
  - stopEvent {Boolean} True to stop the event. That is stop propagation, and prevent the default action.
  - preventDefault {Boolean} True to prevent the default action
  - stopPropagation {Boolean} True to prevent event propagation
  - normalized {Boolean} False to pass a browser event to the handler function instead of an Ext.EventObject
  - delay {Number} The number of milliseconds to delay the invocation of the handler after te event fires.
  - single {Boolean} True to add a handler to handle just the next firing of the event, and then remove itself.
  - buffer {Number} Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

  Combining Options
  Using the options argument, it is possible to combine different types of listeners:
  A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)

  Code:

      el.on('click', this.onClick, this, { single: true, delay: 100, stopEvent : true, forumId: 4 });

  The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers.

  Attaching multiple handlers in 1 call
  Code:

      el.on({ 'click' : { fn: this.onClick scope: this, delay: 100 }, 'mouseover' : { fn: this.onMouseOver scope: this }, 'mouseout' : { fn: this.onMouseOut scope: this } });

  Or a shorthand syntax:
  Code:

      el.on({ 'click' : this.onClick, 'mouseover' : this.onMouseOver, 'mouseout' : this.onMouseOut scope: this });

- `void`
