[Tutor] Tkinter, Frame and Canvas question.

[Gregor Lingl]

Hi Hugo,

some experiments showed, that the following code - using borderwidth=-2 
-  works as you desired, at least on my windows machine:

import Tkinter
from Tkconstants import *

class App(Tkinter.Frame):
   def __init__(self, master=None):
     Tkinter.Frame.__init__(self, master)
     self.pack()
     canvas1 = Tkinter.Canvas(self, background='#000000', borderwidth=-2)
     canvas2 = Tkinter.Canvas(self, background='#000000', borderwidth=-2)
     canvas1.pack(pady=0)
     canvas2.pack(pady=0)

if __name__ == '__main__':
      myapp = App()
      myapp.mainloop()

--------
Alas, there is some strange anomaly: it only does so (i. e. doesn't
display that gray bar between the canvases) when run from IDLE or
by double-clicking the renamed file test.pyw or run from the
command window with the command: python test.py.
Double-clicking test.py performs differently(!) and still shows the 
border between the two canvases. Who understands? (Or do you think my
python installation is in a corrupted state?)

Regards, Gregor
