radio button again!

[vajratkarviraj]

Hi,
Am using Tkinter. Suppose I have 4 radio buttons (value 1,2,3 & 4) arranged in a single column. I want radio 2 to have a normal state and radio 4 to have a disabled state when radio 1 is selected. And radio 2 - disabled, radio 4 - normal when radio 3 is selected (i.e. vice versa). My main question here is how do i get to know the state(i.e. normal or disabled) of a radio button as a feedback? thanx in advance

anybody??? nobody's got a solution?? the main difficulty i am facing is how to effectively use button.configure(state=NORMAL) or button.configure(state=DISABLED)... help will really be appreciated guys... thanks...

master = Tk()
 
def radiobutton_command():
   if radiobutton_var.get() == 1:
      radiobutton_2["state"] = NORMAL
      radiobutton_4["state"] = DISABLED
 
   if radiobutton_var.get() == 2:
      pass
 
   if radiobutton_var.get() == 3:
      radiobutton_2["state"] = DISABLED
      radiobutton_4["state"] = NORMAL
 
   if radiobutton_var.get() == 4:
      pass
 
radiobutton_var = IntVar()
 
radiobutton_1 = Radiobutton(master, text="Button 1", variable=radiobutton_var, value=1, command=radiobutton_command)
radiobutton_1.place(x=0, y=0)
radiobutton_2 = Radiobutton(master, text="Button 2", variable=radiobutton_var, value=2, command=radiobutton_command)
radiobutton_2.place(x=0, y=0)
radiobutton_3 = Radiobutton(master, text="Button 3", variable=radiobutton_var, value=3, command=radiobutton_command)
radiobutton_3.place(x=0, y=0)
radiobutton_4 = Radiobutton(master, text="Button 4", variable=radiobutton_var, value=4, command=radiobutton_command)
radiobutton_4.place(x=0, y=0)
 
master.mainloop()
 

ofcourse you must add more state changes for each radiobutton, for example if you press radiobutton1 and then button2, the state of button4 stays disabled...
