title: What is a good way to show different content dynamically (in Tcl/Tk)?
body: <p>I have a set of <code>radiobuttons</code> (say, with choices 1 and 2) and need to show some widget based off of the user's choice. For example, if they chose 1, I would show them a <code>labelframe</code> with several <code>radiobuttons</code>; whereas, if they chose 2, I would show them a <code>labelframe</code> with some <code>buttons</code>. In either case, the resulting content would be shown in the same area on the window.</p>
  
  <p>What is a good way to switch between multiple widget displays like this?</p>
