Sencha ExtJS 6 Widget Grid 入门

　　最近由于业务需要，研究了一下Sencha ExtJS 6 ，虽然UI和性能上据相关资料说都有提升，但是用起来确实不太顺手，而且用Sencha cmd工具进行测试和发布，很多内部细节都是隐藏的，出了问题不好跟踪。更奇葩的是明明在sencha app watch上运行很好，但是sencha app build后会出现异常。即使是这样，但Sencha ExtJS 6 在UI控件和编程模式上确实比较强大。下面介绍一个 Widget Grid 用法，可以在表格grid中进行列样式渲染，是一个比较强大的功能：

1 拷贝admin-dashboard创建项目

2 配置app.json，主要用于中文提示和采用font-awesome字体库等

    /**
     * The Sencha Framework for this application.
     */
    "framework": "ext",
    "locale": "zh_CN",//中文
    /**
     * The list of required packages (with optional versions; default is "latest").
     * https://docs.sencha.com/extjs/6.0/core_concepts/localization.html
     */
    "requires": [
        "charts",
        "font-awesome",//字体
        "ux",
        "ext-locale"
    ],

3 配置菜单（Admin.store.NavigationTree）

  {
        text: 'Widget Grid',
         view: 'main.SRFX',
         leaf: true,
         iconCls: 'x-fa fa-times-circle',
         routeId: 'SRFX'
 },

4 定义视图和模型等

　在classicsrcviewmain中新建 一个srfxd.js，其内容为：

var store = Ext.create('Ext.data.Store', {
    fields: ['name', 'progress'],
    data: [
        { name: 'Lisa', progress: .159, sequence1: [1, 2, 4, 5, 4, 5], sequence2: [1, -2, 4, 5, 4, -5], sequence3: [1, -2, 4, 5, 4, -5] },
        { name: 'Bart', progress: .216, sequence1: [1, 2, 4, 5, 4, 5], sequence2: [1, -2, 4, 5, 4, -5], sequence3: [1, -2, 4, 5, 4, -5] },
        { name: 'Homer', progress: .55, sequence1: [1, 2, 4, 5, 4, 5], sequence2: [1, -2, 4, 5, 4, -5], sequence3: [1, -2, 4, 5, 4, -5] },
        { name: 'Maggie', progress: .167, sequence1: [1, 2, 4, 5, 4, 5], sequence2: [1, -2, 4, 5, 4, -5], sequence3: [1, -2, 4, 5, 4, -5] },
        { name: 'Marge', progress: .145, sequence1: [1, 2, 4, 5, 4, 5], sequence2: [1, -2, 4, 5, 4, -5], sequence3: [1, -2, 4, 5, 4, -5] }
    ]
});




Ext.define('Admin.view.main.SRFX', {
    extend: 'Ext.grid.Panel',
    requires: [
        'Ext.grid.column.Action',
        'Ext.ProgressBarWidget',
        'Ext.slider.Widget',
        'Ext.sparkline.*'
    ],
    title: '收入分析',
    store: store,
    columns: [
        {
            text: 'Name',
            dataIndex: 'name'
        },
        {
            text: 'progress',
            xtype: 'widgetcolumn',
             120,
            dataIndex: 'progress',
            widget: {
                xtype: 'progressbarwidget',
                textTpl: [
                    '{percent:number("0")}% done'
                ]
            }
        }
        , {
            text: 'Line',
             100,
            dataIndex: 'sequence2',
            xtype: 'widgetcolumn',
            widget: {
                xtype: 'sparklineline',
                tipTpl: 'Value: {y:number("0.00")}'
            }
        }
        , {
            text: 'Bar',
             100,
            dataIndex: 'sequence2',
            xtype: 'widgetcolumn',
            widget: {
                xtype: 'sparklinebar'
            }
        }, {
            text: 'Bullet',
             100,
            dataIndex: 'sequence3',
            xtype: 'widgetcolumn',
            widget: {
                xtype: 'sparklinebullet'
            }
        }
    ],
    height: 350,
     600,
    // renderTo: Ext.getBody()
});
