Getting Frame Size - Tkinter Question

[Sacha Christian Groves]

Hi there and sorry if this has been posted twice,

My problem is that I wish to find out the size of a Frame, that is a
have added x amount of items
to it and now wish to know how high/wide the frame is so that I can
scroll it properly (using a Canvas
wrapper). I'm sure there must be a way of finding out, for example, that
the height is 5 inches or 200 pixels
or something. Howver, I just cannot find that way.

I hope someone out there can help me.

Thanks is advance,

Sacha Groves

Having done

f=Frame(...)
x=Text(f,{Pack:{'side':'top'}})
. . .

you can do

width=f.winfo_reqwidth()
height=f.winfo_reqheight()

before display, or

width=f.winfo_width()
height=f.winfo_height()

afterwards. See the 'winfo' manual page/help entry from Tcl/Tk, and
then check Tkinter.py for calling sequence if you need more help.

Exactly which to use, and whether you need update() or
update_idletasks() before you get a reliable answer, is something
which unfortunately varies from platform to platform (this is a Tk
problem, not a Tkinter one).

YMMV, hope this helps
