Summary: tkFileDialog.SaveAs

Initial Comment:
The SaveAs dialog gets a traceback due to the new
object-style Tk interface.  Run this test program:

from Tkinter import *
import tkFileDialog

def doit():
    savedialog = tkFileDialog.SaveAs(master=root)
    print savedialog.show(initialdir="/tmp",
initialfile="foo.py")

root = Tk()
button = Button(root, text="Save...", command=doit)
button.pack()
mainloop()

I get this traceback:

Traceback (most recent call last):
  File "/usr/local/lib/python2.3/lib-tk/Tkinter.py",
line 1306, in __call__
    return apply(self.func, args)

I see - it appears that the dialogs behave differently on
Windows and X in this respect...

I can see two alternative strategies:

1. Fix this specific problem, by converting the result of
the dialog in _fixresult to string.

2. Enhance the Tk wrapper type, to support all string
operations, by lazily converting itself to a string if a
string method is requested. Then, .rfind would work on the
path object.

There is, in principle, a third alternative:
3. Convert path objects to Python strings, as Python does
not have a separate path type. However, this somewhat
defeats one purpose of using Tcl objects: If the path is
passed back to Tcl, Tcl won't need to reparse it if it is
still a path.

Which of these would you recommend?

Python 2.3a1 (a tad post-release)
Tcl/Tk 8.4
Mandrake Linux 8.1 I believe
Linux kernel 2.2.17-21mdk

The output from that snippet is
<path object at 0x082b3c98> /tmp/foo.py path

Also, can you please try

x=root.tk.call(("tk_getSaveFile","-initialdir","/tmp","-initialfile","foo.py"))
print repr(x),str(x),x.typename

I always get plain strings as a result of that call.

I can't reproduce this. What system and Tcl version?
