I can't figure out how to grey out a Tkinter Checkbutton.
I tried using state=DISABLED but it didn't work and I got an error saying
_tkinter.TclError: bad option "-enable": must be -column, -columnspan, -in, -ipadx, -ipady, -padx, -pady, -row, -rowspan, or -sticky
How can I temporarily disable a Checkbutton?
