ExtJS 4 Grid
原文地址:http://www.showframework.com/2012/07/extjs-4-grids/
此文章翻译的官方文章,感觉还是有一些地方不是很详细
效果图:
Ext.onReady(function () { Ext.define('User', { extend: 'Ext.data.Model', fields: ['name', 'email', 'phone'] }); var userStore = Ext.create('Ext.data.Store', { model: 'User', //使用内联 数据 data: [ { name: 'Lisa', email: 'lisa@simpsons.com', phone: '555-111-1224' }, { name: 'Bart', email: 'bart@simpsons.com', phone: '555-222-1234' }, { name: 'Homer', email: 'home@simpsons.com', phone: '555-222-1244' }, { name: 'Marge', email: 'marge@simpsons.com', phone: '555-222-1254' } ] }); Ext.create('Ext.grid.Panel', { renderTo: Ext.getBody(), store:userStore,//数据源 width: 400, height: 200, title: 'Application Users', columns: [ { text: 'name', width: 100, sortable: false, hideable: false, dataIndex: 'name' }, { text:'Email Address', width:150, dataIndex: 'email', hidden:false //隐藏了 这列 }, { text:'Phone Number', flex:1, dataIndex:'phone' } ] }); });
我们创建了一个表格面板渲染到了body中,并且告诉它从之前创建的userStore
中取得数据,最后我们定义了表格面板有哪些列,用dataIndex
属性配置表格中的列和User Model中的字段的对应关系,Name
列宽度是100,不能排序也不能隐藏,Email Address
列默认是隐藏的(可以通过其他列的菜单控制显示),Phone Number
列自适应表格剩余的宽度
=================================================================================
Fit布局+Grid
在Fit布局中,子元素将自动填满整个父容器。注意:在fit布局下,对其子元素设置宽度是无效的。如果在fit布局中放置了多个组件,则只会显示第一个子元素。典型的案例就是当客户要求一个window或panel中放置一个GRID组件,grid组件的大小会随着父容器的大小改变而改变。
这里的Grid的数据类型使用ArrayStore
Fit布局Grid+ArrayStore

效果图:
测试fit布局下放两个panel,因为默认只能显示一个,另一个必须要隐藏,有些类似于Card布局,只显示一个Panel内的内容:

点击二维展示第二个panel内容。
