Ext类似QQ右上角弹出窗口(转)

?类似qq消息弹窗的窗口 也是在网上找到但是消失的时候有一个黑色的阴影很讨厌,查了些资料稍作修改,只需要配置一个

shadow:false 即可.

?

Ext.namespace("Ext.ux");

Ext.ux.ToastWindowMgr = {
??? positions: []
};

Ext.ux.ToastWindow = Ext.extend(Ext.Window, {
??? initComponent: function(){
????????? Ext.apply(this, {
????????????? iconCls: this.iconCls || 'information',
??????????? width: 250,
??????????? height: 150,
??????????? autoScroll: true,
??????????? autoDestroy: true,
??????????? plain: false,
??????????? shadow:false
????????? });
??????? this.task = new Ext.util.DelayedTask(this.hide, this);
??????? Ext.ux.ToastWindow.superclass.initComponent.call(this);
??? },
??? setMessage: function(msg){
??????? this.body.update(msg);
??? },
??? setTitle: function(title, iconCls){
??????? Ext.ux.ToastWindow.superclass.setTitle.call(this, title, iconCls||this.iconCls);
??? },
??? onRender:function(ct, position) {
??????? Ext.ux.ToastWindow.superclass.onRender.call(this, ct, position);
??? },
??? onDestroy: function(){
??????? Ext.ux.ToastWindowMgr.positions.remove(this.pos);
??????? Ext.ux.ToastWindow.superclass.onDestroy.call(this);
??? },
??? afterShow: function(){
??????? Ext.ux.ToastWindow.superclass.afterShow.call(this);
??????? this.on('move', function(){
?????????????? Ext.ux.ToastWindowMgr.positions.remove(this.pos);
??????????? this.task.cancel();}
??????? , this);
??????? this.task.delay(4000);
??? },
??? animShow: function(){
??????? this.pos = 0;
??????? while(Ext.ux.ToastWindowMgr.positions.indexOf(this.pos)>-1)
??????????? this.pos++;
??????? Ext.ux.ToastWindowMgr.positions.push(this.pos);
??????? this.setSize(250,150);
??????? this.el.alignTo(document, "br-br", [ -20, -20-((this.getSize().height+10)*this.pos) ]);
??????? this.el.slideIn('b', {
??????????? duration: 2,
??????????? callback: this.afterShow,
??????????? scope: this
??????? });???
??? },
??? animHide: function(){
?????????? Ext.ux.ToastWindowMgr.positions.remove(this.pos);
??????? this.el.ghost("b", {

/*Ext.onReady(function(){
