What follows looks more like a spec than a question.

Here's my implementation:
import Tkinter as tk
class Radiogrid(tk.Frame):
def __init__(self, master, columns, trace_write=None):
tk.Frame.__init__(self)
self.variables = []
self.buttons = []
for x, column in enumerate(columns):
var = tk.IntVar()
if trace_write:
var.trace_variable("w", trace_write)
self.variables.append(var)
self.buttons.append([])
for y, text in enumerate(column):
rbn = tk.Radiobutton(self, text=text, variable=var, value=y)
rbn.grid(column=x, row=y)
self.buttons[-1].append(rbn)
def get_row_state(self, row):
return tuple(row == var.get() for var in self.variables)
if __name__ == "__main__":
root = tk.Tk()
def show_state(*args):
for i in range(3):
print "row", i, rg.get_row_state(i)
print
rg = Radiogrid(root,
["alpha beta gamma".split(),
"one two three".split(),
"guido van rossum".split()],
show_state
)
rg.pack()
root.mainloop()
I hope this will move further discussion from the abstract to the
concrete :-)
