Hi Alan, thanks for the reply and my apologies for not realizing there was a
Tkinter-discuss group. After even more searching, this seems to be
something weird with my version of Tkinter and/or my installation. I can
eliminate this effect on my machine (linux, python 2.6) by explicitly
creating and destroying a toplevel window after the askdirectory() dialog,
as such:
import tkFileDialog,tkMessageBox
import Tkinter
toplevel=Tkinter.Tk()
addDirectory=tkMessageBox.askyesno('a dialog','Add a directory?')
print addDirectory
theDirectory=tkFileDialog.askdirectory()
toplevel.destroy()
addDirectory=tkMessageBox.askyesno('a dialog','Add a directory?')
print addDirectory
If I remove the "toplevel.destroy()" call, I get incorrect behavior.
However, if I run the same program on my windows installation (python 2.5),
I get correct behavior regardless of the presence of this destroy() command,
which I'm pretty sure must be the expected behavior. I will look into my
tkinter version and file a bug report if I convince myself my install's not
goofy- I get the same behavior with my 3.1 installation on my linux box.
Regarding teh print statements, I was using python 3 syntax but running
python 2.6...I just like the 3 syntax better, sorry for the confusion. The
extra prints were just me getting carried away with debugging, I love
printing stuff.
