# Class Ext.grid.GridView

Package: | Ext.grid
Defined In: | GridView.js
Class: | GridView
Subclasses: | GroupingView
Extends: | Observable

This class encapsulates the user interface of an Ext.grid.GridPanel. Methods of this class may be used to access user interface elements to enable special display effects. Do not change the DOM structure of the user interface.

This class does not provide ways to manipulate the underlying data. The data model of a Grid is held in an Ext.data.Store.

## Config Options

Config Options | Defined By
--- | ---
| autoFill : Boolean True to auto expand the columns to fit the grid when the grid is created. | GridView
| emptyText : String Default text to display in the grid body when no rows are available (defaults to ''). | GridView
| enableRowBody : Boolean True to add a second TR element per row that can be used to provide a row body that spans beneath the data row. Use t... True to add a second TR element per row that can be used to provide a row body that spans beneath the data row. Use the getRowClass method's rowParams config to customize the row body. | GridView
| forceFit : Boolean True to auto expand/contract the size of the columns to fit the grid width and prevent horizontal scrolling. | GridView
| listeners : Object A config object containing one or more event handlers to be added to this object during initialization. This should b... 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

## Public Methods

Method | Defined By
--- | ---
| GridView( `Object config` ) Parameters: `config` : Object Returns: `` | GridView
| 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
      });

You can also supply custom parameters to the row template for the current row to customize how it is rendered using the rowParams parameter. This function should return the CSS class name (or empty string '' for none) that will be added to the row's wrapping div.
