i coding python script can display buttons select label.
this program containing 4 radiobutton , 1 label.
so far problem of program program can not repeated. need have border surround label.
i using python 2.7 , cannot post image because don't have enough reputation
= label(the_window, text = 'null', fg = 'black',font = ('times', 36), width = 8) button.grid(row=2,column=1) button.grid(row=3,column=1) button.grid(row=2,column=2) button.grid(row=3,column=2) this setup
you can add border label specifying relief:
direction_status = label(the_window, text = 'null', fg = 'black', font = ('times', 36), width = 8, relief=groove) rather using 4 booleanvars value attributes radio buttons, use single intvar. indicate tkinter radio buttons belong in same group, , ensure 1 can selected @ time.
