title: How to show close button on top of stage webview in Flex stagewebview for facebook
body: <p>I have Flex AIR app which uses StageWebView to load facebook login window. I want to add close button to stageWebView.
  Is there any native function for stageWebView to add close button on top of StageWebView?
  I have added close button, but it is not coming on top of StageWebView, because we cant add anything on top of StageWebView.</p>
