visible="false"隐藏不了，如何解决？

[成长中]

TabNavigator里有多个Canvas，我想隐藏其中几个Canvas，如果操作，我试了直接在Canvas里设置visible="false"隐藏不了，哪位帮我解决一下！

好像只能通过删除/添加子组件的方式来达到这个目的：

<?xml version="1.0" encoding="utf-8"?> 
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" fontSize="12">  
    <mx:Script>
    	<![CDATA[
    		private function onBtnTestClick(event:Event):void {
    			if(tabNav.numChildren == 1) {
    				tabNav.addChild(removeableChild);
    			} else {
    				tabNav.removeChild(removeableChild);
    			}
    		}
    	]]>
    </mx:Script>
    <mx:TabNavigator id="tabNav" width="80%" height="80%">
    	<mx:Canvas label="ok1">
    		<mx:Label text="ok1"/>
    	</mx:Canvas>
    	<mx:Canvas label="ok2" id="removeableChild">
    		<mx:Label text="ok2"/>
    	</mx:Canvas>
    </mx:TabNavigator>
    <mx:Button id="btnTest" click="onBtnTestClick(event)" label="Click Me"/>
</mx:Application>

试着把includeInLayout="flase"看看

你可以试试在后台页面构造函数里写
this.canvas1.visibile = Visibility = Visibility.Collapsed;

[sksk1128]

this.canvas1.Visibility=Visibility.Collapsed

2楼说的对
xx.visible = xx.includeInLayout = false;
