# Class Ext.grid.AbstractSelectionModel

Package: | Ext.grid
Defined In: | AbstractSelectionModel.js
Class: | AbstractSelectionModel
Subclasses: | CellSelectionModel, RowSelectionModel
Extends: | Observable

Abstract base class for grid SelectionModels. It provides the interface that should be implemented by descendant classes. This class should not be directly instantiated.

A config object containing one or more event handlers to be added to this object during initialization. This should be a valid listeners config object as specified in the addListener example for attaching multiple handlers at once. | Observable

AbstractSelectionModel()
Parameters:

- None.

Returns:

- ``

AbstractSelectionModel

addEvents( `Object object` ) : void
Used to define events on this Observable
Used to define events on this Observable
Parameters:

- `object` : Object
  The object with the events defined

Returns:

- `void`

Observable

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

  - delay : Number

    The number of milliseconds to delay the invocation of the handler after the 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)

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

  Attaching multiple handlers in 1 call
  The method also allows for a single argument to be passed which is a config object containing properties which specify multiple handlers.

      foo.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:

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

Returns:

- `void`

Observable

fireEvent( `String eventName`, `Object... args` ) : Boolean

Fires the specified event with the passed parameters (minus the event name).
Parameters:

- `eventName` : String
- `args` : Object...
  Variable number of parameters are passed to handlers

Returns:

- `Boolean`
  returns false if any of the handlers return false otherwise it returns true

Observable

hasListener( `String eventName` ) : Boolean
Checks to see if this object has any listeners for a specified event
Checks to see if this object has any listeners for a specified event
Parameters:

- `eventName` : String
  The name of the event to check for

Returns:

- `Boolean`
  True if the event is being listened for, else false
