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|

        * ``fileName`` (**str**): name of file to open.

        |Returns|

        * **None**

        |Raises|

        * **None**
