Actionscript 3 Flex 4.0选项卡栏删除选项卡和内容

我有一个

选项卡栏

，在CTRL+ALT+单击（关闭按钮）时，我想关闭所有选项卡，并删除它们的内容

在每个选项卡的退出按钮上添加事件侦听器：

    public static var CONTROL_PRESSED:Boolean = false;
    public static var ALT_PRESSED:Boolean = false;
this.tabBar.addEventListener(ChildExistenceChangedEvent.CHILD_ADD, function(event:ChildExistenceChangedEvent):void{
            var tab:SuperTab = SuperTab(event.relatedObject);
            tab.addEventListener(FlexEvent.CREATION_COMPLETE, function(event:FlexEvent):void{
                for(var i:int = 0; i < tab.numChildren; i+=1){
                    if(tab.getChildAt(i) is Button){
                        var exitButton:Button = Button(tab.getChildAt(i));

                        exitButton.addEventListener(MouseEvent.MOUSE_DOWN, function(event:MouseEvent):void{
                            if(event.altKey){
                                ALT_PRESSED = true;
                            }else{
                                ALT_PRESSED = false;
                            }
                            if(event.ctrlKey){
                                CONTROL_PRESSED = true;
                            }else{
                                CONTROL_PRESSED = false;
                            }
                        }, false, 1000);
                        model.tabExitButtonArray.push(exitButton);
                    }
                }
            });
        });

更改选项卡栏所选索引，并以删除单个选项卡的方式删除每个选项卡。这将删除第一个当前选项卡

        for(var i:int = 0; i< model.tabExitButtonArray.length; i++){
        model.tabBar.selectedIndex = i;

        Class.dispatchEvent(new CustomEvent(object, function));
    }

你试过移除数据提供者吗？@FlorianLavorel，我该怎么做<代码>数据提供程序=新数组（）？

model.tabBar.removeAllChildren();

        for(var i:int = 0; i< model.tabExitButtonArray.length; i++){
        model.tabBar.selectedIndex = i;

        Class.dispatchEvent(new CustomEvent(object, function));
    }

    model.tabBar.removeAllChildren();
    model.tabBar.dataProvider = new Array();
