That's what I'm using. Should work for any unix and windows - don't know ab=
out=20
Mac though.

        if sys.platform[:3] =3D=3D 'win':
            # windows launch
            try:
                os.startfile(_tmppath)
            except:
                traceback.print_exc()

        elif sys.platform[:5] =3D=3D 'linux':
            # linux launch
            if os.fork() =3D=3D 0:      =20
                os.execlp(_tmpapp,_tmpapp,_tmppath) =20

_tmpapp is determined by using the file magic (mimetype) and my program has=
 a=20
setup where I can set which application to use for which mimetype. _tmppath=
=20
is the document to view. There are many ways to find the mimetype, so you'd=
=20
have to read the python libs documentation or AFAICT there is a wx.MimeType=
=20
class too.

hope that helps
