Flash安全设置面板 - 收听关闭事件？

Question

将Flash与麦克风或摄像头一起使用时,系统会提示用户允许访问这些设备.这是通过内置的安全设置面板完成的.

当用户单击安全设置面板的关闭按钮时,是否有一种方法可以被事件处理程序通知？这似乎不可能......

对于麦克风,当用户更改安全面板中的设置时,可以接收状态事件,但是当用户仍然打开面板时会触发此事件.

在尝试搜索解决方案时,我偶然发现了这一点.

Flash Player错误报告WITH WORKAROUND

我还没有测试过这个解决方法,但它应该还能运行吗？祝好运.

编辑:

对于那些不能/不会访问Adobe bug跟踪器的人来说,这是Philippe Piernot最初发布的解决方法:

var closed:Boolean = true;
var dummy:BitmapData;
dummy = new BitmapData(1, 1);

try
{
    // Try to capture the stage: triggers a Security error when the settings dialog box is open
    dummy.draw(stage);
}
catch (error:Error)
{
    closed = false;
}

dummy.dispose();
dummy = null;

呼叫安全面板(如ns.addStream(mic))

            // WHEN PRIVACY PANEL IS ON MOUSE EVENTS ARE DISABLED
            stage.addEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
            function onMouseOver(e:Event):void { 
                trace("privacy panel closed");
                //REMOVE THE LISTENER ON FIRST TIME
                stage.removeEventListener(MouseEvent.MOUSE_OVER, onMouseOver);
                //doStuff
            }

我已经在下一个方面解决了这个问题:

private function showPrivacyDialog():void {
    var spr:Sprite = new Sprite();
    stage.focus = spr;
    spr.addEventListener( FocusEvent.FOCUS_OUT, handleFocusEvent );
    spr.addEventListener( FocusEvent.FOCUS_IN, handleFocusEvent );
    Security.showSettings( SecurityPanel.PRIVACY );
}

private function handleFocusEvent( event:Event ):void {
    event.target.removeEventListener( event.type, handleFocusEvent );
    const closed:Boolean = (event.type == FocusEvent.FOCUS_IN);
    trace( "Security Panel just", closed ? "closed!" : "shown!" );
    if (closed) {
        stage.focus = null; // or it can be restored to the previous value
    }
}

检查显示设置对话框的完整util类SecurityPanelUtil,然后将其处理为关闭并立即通过回调通知.
