There doesn't seem to be something obvious.
I tried to use the option database with:

root.option_add('*TkFDialog*width', 40)
root.option_add('*TkFDialog*height', 40)

which to my surprise actually made the dialog rather wide (though I am
not sure about the units, but had no effect on the dialog's height.

Then I tried another, more ambtious approach, with:

root.tk.call('wm', 'geometry', '.__tk_filedialog', '800x600')

which apparently fails if no dialog windoe has been created yet. Finally I
actually got it working, with this somewhat weird bit of code:

#########################################################################
from Tkinter import *
from tkFileDialog import askopenfilename, asksaveasfilename

root=Tk()

def test():
    #print 'test'
    try:
        w, h = root.winfo_screenwidth(), root.winfo_screenheight()
        x, y = w / 2 - 400, h /2 - 300
        root.tk.call('wm', 'geometry', '.__tk_filedialog',
                        '800x600+%d+%d' % (x, y))
    except TclError:
        root.after(100, test)
test()

def test1(ev):
    askopenfilename()
def test2(ev):
    asksaveasfilename()

root.bind('<F1>', test1)
root.bind('<F2>', test2)

root.mainloop()
#########################################################################

Hmm... the "center on screen" gimmick works only with the first dialog,
can someone fix that ;)
Anyway, unless we come up with something better, I'd classify this as
strictly "don't try this at home"-ish :)

Regards

Michael
