docs: Overload this method with applet specific code that can make
          sense of the passed ``fileName`` argument. In many case this
          will literally mean a file name, but could equally well be a
          URL (eg. ``QWebView`` based applets) or any other resource
          descriptor, as long as it is in text form.
  
          |Args|
