    tkFileDialog different between Linux and Windows

    I'm using Python 2.3.2 and tkFileDialog in a program I have. I'm
    trying to use this on Linux (RH 8.0) and Windows 2000. When I first
    upgraded from v2.2 to v2.3. I noticed that
    tkFileDialog.as kopenfilename() returns a tuple on Cancel instead of
    ''. I found that the Windows version still returns a string (''). Now
    I'm finding out that tkFileDialog.Di rectory().show( ) does this too.
    [color=blue][color=green][color=darkred]
    >>> d1=tkFileDialog .Directory().sh ow()
    >>> d2=tkFileDialog .Directory().sh ow()
    >>> type(d1),type(d 2)[/color][/color][/color]
    (<type 'tuple'>, <type '_tkinter.Tcl_O bj'>)[color=blue][color=green][color=darkred]
    >>> d2[/color][/color][/color]
    <path object at 0x08295a48>[color=blue][color=green][color=darkred]
    >>> d2[/color][/color][/color]
    <path object at 0x08295a48>


    d1 is the result of a Cancel, d2 is the result of a Ok.
    [color=blue][color=green][color=darkred]
    >>> dir(d1)[/color][/color][/color]
    ['__add__', '__class__', '__contains__', '__delattr__', '__doc__',
    '__eq__', '__ge__', '__getattribute __', '__getitem__',
    '__getnewargs__ ', '__getslice__', '__gt__', '__hash__', '__init__',
    '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__',
    '__new__', '__reduce__', '__reduce_ex__' , '__repr__', '__rmul__',
    '__setattr__', '__str__']
    [color=blue][color=green][color=darkred]
    >>> dir(d2)[/color][/color][/color]
    ['__class__', '__cmp__', '__delattr__', '__doc__', '__getattribute __',
    '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__' ,
    '__repr__', '__setattr__', '__str__', '__unicode__', 'string',
    'typename']


    I thought this was a Tk8.3 vs Tk8.4 problem, so I put in a check:

    d = tkFileDialog.Di rectory().show( )
    if TkVersion < 8.4:
    outdir=d
    else:
    outdir=d.string
    if d : self.setoutpath (outdir)

    Then when I tried this on a Windows machine, it turns out that
    tkFileDialog.Di rectory().show( ) still returns a string when TkVersion
    is 8.4

    How can I check tkFileDialog to do the "right" thing? All I want is
    the string that contains the path, but I want this to work on both
    Linux and Windows.

    Thanks.

      Is this the sort of thing you want?

      dirobj = tkFileDialog.as kdirectory()
      if not dirobj:
      # user Cancelled; works whether the return is '' or ()
      return

      # dirobj may be a string or a Tk_Obj
      dirname = unicode(dirobj)

      The same code should work for askopenfilename .
