title: Custom row in wxListCtrl
body: <p>Is it possible to use/create a custom row for wxListCtrl?
  I need to show a dinamic list composed by more elements (text, progressbar, buttons). Something like this:</p>
  
  <p>1 - text - progress-bar - button1, button2, button3, button 4</p>
  
  <p>2 - text - progress-bar - button1, button2, button3, button 4</p>
  
  <p>...</p>
  
  <p>The documentation only explains how to create a text-based wxListCtrl. Anyone knows how to create it?</p>
