Class Ext.ux.grid.CheckColumn

A Column subclass which renders a checkbox in each column cell which toggles the truthiness of the associated data field on click.

Note. As of ExtJS 3.3 this no longer has to be configured as a plugin of the GridPanel.

Example usage:

var cm = new Ext.grid.ColumnModel([{
       header: 'Foo',
       ...
    },{
       xtype: 'checkcolumn',
       header: 'Indoor?',
       dataIndex: 'indoor',
       width: 55
    }
]);

// create the grid
var grid = new Ext.grid.EditorGridPanel({
    ...
    colModel: cm,
    ...
});

In addition to toggling a Boolean value within the record data, this class toggles a css class between 'x-grid3-check-col' and 'x-grid3-check-col-on' to alter the background image used for a column.
