/** * @class Ext.grid.GridView * @extends Ext.util.Observable *

This class encapsulates the user interface of an {@link 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 {@link Ext.data.Store}.

* @constructor * @param {Object} config */ Ext.grid.GridView = Ext.extend(Ext.util.Observable, {
/** * Override this function to apply custom CSS classes to rows during rendering. 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. To apply multiple class names, simply return them space-delimited within the string * (e.g., 'my-class another-class'). Example usage:

viewConfig: {
    forceFit: true,
    showPreview: true, // custom property
    enableRowBody: true, // required to create a second, full-width row to show expanded Record data
    getRowClass: function(record, rowIndex, rp, ds){ // rp = rowParams
