ExtJS 4.0中,如何动态改变一个rowEditor中的组件?

比如,如果一个combo选了第一项,就把同一行的另外一个组件变成datefield,如果选了第二项,就把那个组件变成textfield。

API里说是用setEditor,但参数写的是field。

我这样写的话:
[code="java"] Ext.getCmp('quote_item_grid').columns[0].setEditor(new Ext.form.field.Text({value: 3}));[/code]

报错:column.getEditor is not a function

有好多这样问的,都说用setEditor,但好像都是3.3的,4.0是不是不一样了呢?

有人说在前面加一个参数columnNumber,我试了貌似也不行,报同样的错……

    你发的那个网站,我没用明白 :oops: ,没找到怎么引入ext的样式文件。
    [url]%EXT_HOME%\ext-4.0.2-gpl\ext-4.0.2\examples\grid\array-grid.js[/url]在你的ext的包下面这个路径的这个文件内容换成我这个,然后你浏览array-grid.html看看。
    [code="java"]
    Ext.require([
    'Ext.grid.*',
    'Ext.data.*',
    'Ext.util.*',
    'Ext.state.*'
    ]);

    Ext.onReady(function() {
    Ext.QuickTips.init();

    // setup the state provider, all state information will be saved to a cookie
    Ext.state.Manager.setProvider(Ext.create('Ext.state.CookieProvider'));
    
    // sample static data for the store
    var myData = [

    这个做的是第一列的editor是个combo,选第一项的话,第二列的editor为文本,选第二项,第二列的editor为日期。
