Ext desktop 图标自动换行代码，,完美解决desktop图

完美解决desktop图标换行问题 在desktop.js中扩展一个函数 initShortcut : function() {         var btnHeight = 64;         var btnWidth = 64;         var btnPadding = 30;         var col = {index : 1,x : btnPadding};         var row = {index : 1,y : btnPadding};         var bottom;         var numberOfItems = 0;         var taskBarHeight = Ext.query(".ux-taskbar")[0].clientHeight + 40;         var bodyHeight = Ext.getBody().getHeight() - taskBarHeight;         var items = Ext.query(".ux-desktop-shortcut");         for (var i = 0, len = items.length; i < len; i++) {             numberOfItems += 1;             bottom = row.y + btnHeight;             if (((bodyHeight < bottom) ? true : false) && bottom > (btnHeight + btnPadding)) {                 numberOfItems = 0;                 col = {index : col.index++,x : col.x + btnWidth + btnPadding};                 row = {index : 1,y : btnPadding};             }             Ext.fly(items[i]).setXY([col.x, row.y]);             row.index++;             row.y = row.y + btnHeight + btnPadding;         }     } 在createDataView添加一个监听器 createDataView: function () {         var me = this;         return {             xtype: 'dataview',             overItemCls: 'x-view-over',             trackOver: true,             itemSelector: me.shortcutItemSelector,             store: me.shortcuts,             tpl: new Ext.XTemplate(me.shortcutTpl),             listeners:{                 resize:me.initShortcut             }         };     } 在afterRender渲染结束时调用函数 afterRender: function () {         var me = this;         me.callParent();         me.el.on('contextmenu', me.onDesktopMenu, me);         Ext.Function.defer(me.initShortcut,1);     }//该片段来自于http://byrx.net
