* @class Ext.grid.GridPanel
* @extends Ext.Panel
* This class represents the primary interface of a component based grid control to represent data
* in a tabular format of rows and columns. The GridPanel is composed of the following:
* <div class="mdetail-params"><ul>
* <li>{@link Ext.data.Store Store} : The Model holding the data records (rows)
* <div class="sub-desc"></div></li>
* <li>{@link Ext.grid.ColumnModel Column model} : Column makeup
* <div class="sub-desc"></div></li>
* <li>{@link Ext.grid.GridView View} : Encapsulates the user interface
* <div class="sub-desc"></div></li>
* <li>{@link Ext.grid.AbstractSelectionModel selection model} : Selection behavior
* <div class="sub-desc"></div></li>
* </ul></div>
* Example usage:
* <pre><code>
var grid = new Ext.grid.GridPanel({
{@link #store}: new (@link Ext.data.Store}({
{@link Ext.data.Store#autoDestroy autoDestroy}: true,
{@link Ext.data.Store#reader reader}: reader,
{@link Ext.data.Store#data data}: xg.dummyData
}),
{@link #columns}: [
{id: 'company', header: 'Company', width: 200, sortable: true, dataIndex: 'company'},
{header: 'Price', width: 120, sortable: true, renderer: Ext.util.Format.usMoney, dataIndex: 'price'},
{header: 'Change', width: 120, sortable: true, dataIndex: 'change'},
{header: '% Change', width: 120, sortable: true, dataIndex: 'pctChange'},
// instead of specifying renderer: Ext.util.Format.dateRenderer('m/d/Y') use xtype
{header: 'Last Updated', width: 135, sortable: true, dataIndex: 'lastChange', xtype: 'datecolumn', format: 'M d, Y'}
],
{@link #viewConfig}: {
{@link Ext.grid.GridView#forceFit forceFit}: true,
// Return CSS class to apply to rows depending upon data values
{@link Ext.grid.GridView#getRowClass getRowClass}: function(record, index) {
var c = record.{@link Ext.data.Record#get get}('change');
if (c < 0) {
return 'price-fall';
} else if (c > 0) {
return 'price-rise';
}
}
},
{@link #sm}: new Ext.grid.RowSelectionModel({singleSelect:true}),
width: 600,
height: 300,
frame: true,
title: 'Framed with Row Selection and Horizontal Scrolling',
iconCls: 'icon-grid'
});
* </code></pre>
* Notes:
* <div class="mdetail-params"><ul>
* <li>Although this class inherits many configuration options from base classes, some of them
* (such as autoScroll, autoWidth, layout, items, etc) are not used by this class, and will
* have no effect.</li>
* <li>A grid requires a width in which to scroll its columns, and a height in which to
* scroll its rows. These dimensions can either be set explicitly through the
* <tt>{@link Ext.BoxComponent#height height}</tt> and <tt>{@link Ext.BoxComponent#width width}</tt>
* configuration options or implicitly set by using the grid as a child item of a
* {@link Ext.Container Container} which will have a {@link Ext.Container#layout layout manager}
* provide the sizing of its child items (for example the Container of the Grid may specify
* <tt>{@link Ext.Container#layout layout}:'fit'</tt>).</li>
* <li>To access the data in a Grid, it is necessary to use the data model encapsulated
* by the {@link #store Store}. See the {@link #cellclick} event for more details.</li>
* </ul></div>
