Hi Mick,
Sorry about that. The code below does work, however, in my case its a
little more complex. I'll try and explain. I've put most of the code
into different modules which get imported in the usual way, so I have
one that has all the classes for the menu bar. There is also a class in
here which generates the tkSimpleDialog for the preferences. Is is here
that I've got the bit of code I posted below.
__main__.angles is set correctly, and if I do:
print tk.StringVar.get(angles)
I get the correct result.
I'm a little confused. Also if I put angles into an Entry widget it is
correct.
Thanks for your help,
Iain

Dear Iain,
Makes it easier to test your code if you provide
a standalone example.
I modified your code as follows to get it to run:
import Tkinter as tk
master = tk.Tk()
settings = tk.LabelFrame(master, text="Settings")
settings.grid(row=0, column=0)
tk.Label(settings, text="Angular Units: ").grid(row=0, column=0, sticky=tk.E)
angles = tk.StringVar(value='radians')
tk.Radiobutton(settings, text="Degrees", variable=angles,
value='degrees').grid(row=0, column=1)
tk.Radiobutton(settings, text="Radians", variable=angles,
value='radians').grid(row=0, column=2)
master.mainloop()
...and on my Macosx running python 2.5.2 it runs fine, with buttons selected.
My bet is that angles is not in fact set, or is not set
to one of 'degrees' or 'radians'. Put a print statement to
see what value __main__.angles has at the point of
setting the variable angles.

Hi,
I'm trying to create a preferences dialog. At the moment, I'm just reading a
config file using ConfigParser and displaying this in a tkSimpleDialog.
I've got some Entry widgets working okay, but I can't get the radiobuttons
to work. The code is:
import Tkinter as tk
settings = tk.LabelFrame(master, text="Settings")
settings.grid(row=0, column=0)
tk.Label(settings, text="Angular Units: ").grid(row=0, column=0,
sticky=tk.E)
angles = tk.StringVar(value=__main__.angles)
tk.Radiobutton(settings, text="Degrees", variable=angles,
value='degrees').grid(row=0, column=1)
tk.Radiobutton(settings, text="Radians", variable=angles,
value='radians').grid(row=0, column=2)
When I run this, angles is set to degrees but I don't get the radiobutton
active (either of them).
What am I doing wrong?
Thanks,
Iain
