[Tkinter-discuss] Confused by frames

[Chris Niekel]

Hi,

I'm trying to combine a couple of widgets into a frame as a reusable
component. Somehow though, things change when I put some part in a class,
derived from Frame.

Version 1:

class F1(Frame):
    def __init__(self, *args, **kw):
        Frame.__init__(self, *args, **kw)
        Label(text="F1").grid(row=5,column=5)
r = Tk()

b = Button(r, text='button').grid(row=0,column=1)
f = F1(r).grid(row=0,column=0)
r.mainloop()

Version 2:

from Tkinter import *
r = Tk()

b = Button(r, text='button').grid(row=0,column=1)
f1 = Frame(r)
f1.grid(row=0,column=0)
Label(f1, text='F1').grid(row=5,column=5)
r.mainloop()


I would think these are equivalent, but they're not. Version 2 has the
behaviour I expect (a new frame, so the label is on the left).

Did I do something wrong in version 1, or is there another way to make a
class with the label which behaves like a frame?

Regards,
Chris
