title: Python 3 tkinter: dynamically set an element's state to "normal"?
body: <p>I'm pretty new to python, especially using tkinter. So far I have put together a ttk notebook with the help of this page <a href="http://www.pyinmyeye.com/2012/08/tkinter-notebook-demo.html" rel="nofollow">http://www.pyinmyeye.com/2012/08/tkinter-notebook-demo.html</a>.</p>
  
  <p>What I am essentially asking is- can I dynamically set the second tab's <em>state</em> from "<em>disabled</em>" to "<em>normal</em>" when I press a ttk button in the first "<em>Welcome</em>" tab?</p>
  
  <p>What the tabs are initially set to:</p>
  
  <pre><code>nb.add(frame, text='Welcome', underline=0, padding=2, state="normal")
  nb.add(frame, text='Tab Two', underline=0, padding=2, state="disabled")
  </code></pre>
  
  <p>If it helps to put this into context, I am trying to make a pizza ordering program for a school project, and I want each step of the process in a different tab. I want the state of these tabs to depend on whether the pizzas are to be delivered or picked up; in which case some steps are not needed.
  Thanks to anyone who even takes the time to read this :)</p>
