extjs - 如何在 Ext.grid.panel 中定义 View

Question

我想修改网格的 View ，我从基础开始(即在我定义自己的 View 之前)。但是有些我什至无法将对象分配给查看属性。拜托，有人知道如何创建 View 吗？我试过跟随。

例子会很棒。

var viewConfig = {emptyText: "My msg",stripeRows: false};

this.grid = Ext.create('Ext.grid.Panel', {
            id: "t-"+this.gridName+"-grid",
            header: true,
            title: gridTitle,
            border: false,
            store: store,            
            columns: cm,
            selModel: sm,
            loadMask: true,
            //viewConfig: viewConfig, // works fine
            //view: new Ext.view.Table() ,//Ext.grid.View(),//Ext.grid.View(viewConfig ),
            provider: this.page.provider
        });

如果我取消注释“view: new Ext.view.Table()”行，那么它会引发错误并停止一切。我一直在评论，在创建网格后，我可以使用 this.grid.getView() 属性访问 View 。但是如何创建自己的 View 对象(我可以在其中分配自定义模板)？？？

非常感谢。

来自文档:

This is the base class for both Ext.grid.View and Ext.tree.View and is not to be used directly.

如果您确实想自己创建一个，则需要配置以下必需 选项。

itemSelector : String
store : Ext.data.Store
tpl : String/String[]

看into the docs如何创建自定义 View 。祝你好运!如果您需要任何帮助，请随时提出；)

Ext.define('Image', {
    extend: 'Ext.data.Model',
    fields: [
        { name:'src', type:'string' },
        { name:'caption', type:'string' }
    ]
});

Ext.create('Ext.data.Store', {
    id:'imagesStore',
    model: 'Image',
    data: [
        { src:'http://www.sencha.com/img/20110215-feat-drawing.png', caption:'Drawing & Charts' },
        { src:'http://www.sencha.com/img/20110215-feat-data.png', caption:'Advanced Data' },
        { src:'http://www.sencha.com/img/20110215-feat-html5.png', caption:'Overhauled Theme' },
        { src:'http://www.sencha.com/img/20110215-feat-perf.png', caption:'Performance Tuned' }
    ]
});

var imageTpl = new Ext.XTemplate(
    '<tpl for=".">',
        '<div style="margin-bottom: 10px;" class="thumb-wrap">',
          '<img src="{src}" />',
          '<br/><span>{caption}</span>',
        '</div>',
    '</tpl>'
);

var theView = Ext.create('Ext.view.View', {
    store: Ext.data.StoreManager.lookup('imagesStore'),
    tpl: imageTpl,
    itemSelector: 'div.thumb-wrap',
    emptyText: 'No images available'
});

var grid = Ext.create('Ext.grid.Panel', {
    id: "t-"+this.gridName+"-grid",
    header: true,
    title: gridTitle,
    border: false,
    store: store,            
    columns: cm,
    selModel: sm,
    loadMask: true,
    view: theView,
    provider: this.page.provider,
    renderTo: Ext.getBody()
});
//not tested but should work
