I think a quick way to change the options of a widget is using the configure method    In your case  it would look like this   self x configure state NORMAL

You simply have to set the state of the your button self x to normal   self x  state      normal    or  self x config state  normal     This code would go in the callback for the event that will cause the Button to be enabled     Also  the right code should be   self x   Button self dialog  text  Download   state DISABLED  command self download  self x pack side LEFT    The method pack in Button      pack   returns None  and you are assigning it to self x   You actually want to assign the return value of Button      to self x  and then  in the following line  use self x pack

This is what worked for me  I am not sure why the syntax is different  But it was extremely frustrating trying every combination of activate  inactive  deactivated  disabled  etc  In lower case upper case in quotes out of quotes in brackets out of brackets etc   Well  here s the winning combination for me  for some reason   different than everyone else   import tkinter  class App object       def   init   self           self tree   None         self  setup widgets        def  setup widgets self           butts   tkinter Button text    add line   state  disabled           butts grid    def main          root   tkinter Tk       app   App       root mainloop    if   name         main         main
