Hide output windows

Hi!

In my application I have output window in a minimized window group. I can show it using this code:
TopComponent outputWindow = WindowManager.getDefault().findTopComponent("output");
if (outputWindow != null) {
     if (outputWindow.isOpened() == false) {
         outputWindow.open();
     }

     outputWindow.requestVisible();
}

this brings it up and pressing ESC hides it again.
How can I do so that it will hide after 5 secounds?

Best regards,
    Kovi
