I haven't been able to find a way to do that in Tkinter yet. Lemme know if you find a solution.
Of course, you could create your own class. Here's a cheesy little attempt:
from Tkinter import *
class ComboButton(Frame):
def __init__(self, master,text='',variable=None, value=""):
Frame.__init__(self,master)
self.label = Label(self,text=text)
self.button = Radiobutton(self,text='',variable=variable, value=value)
self.variable = variable
self.button.grid()
self.label.grid()
mainw = Tk()
v = StringVar()
mainw.f = ComboButton(mainw,"Option 1", value="Option 1",variable=v)
mainw.f.grid()
mainw.mainloop()
This class has the added bonus that the control variable is
*gasp* part of the radiobutton object! Who could have thought of such an innovation?!?! </sarcasm>
(answer: one of my students, who was disgusted that he had to use dictionaries to keep track of the control variables for radiobutton and checkbutton widgets).
Anyways, this is just a sketch ... a real implementation would allow the user to pass all of the relevant properties for the radiobutton and the label.
