title: Wxpython - remove tabs in application
body: <p>I have a application which I have previously been using multiple tabs. I have since changed the application and now only need a single panel. My issue is I can't seem to figure out how I get rid of the redundant tabs and revert to a single panel. Removing the <code>self.tabbed</code> in line 12 and 13 just result in a very odd looking panel, everything squashed to the corner. Below is the current tabbed code, I have removed lots of irrelevant code / classes, etc. What would be the most efficient way without effecting too much code?</p>
  
  <p>UPDATE 1:</p>
  
  <p>I have updated the below code, so it now runs.</p>
