title: Embedding a Traits UI gui of kind="subpanel" in another window
body: <p>In the traitsui documentation it states that </p>
  
  <blockquote>
    <p>Blockquote A panel is very similar to a window, except that it is embedded in a larger window, which need not be a Traits UI window.</p>
  </blockquote>
  
  <p>Does anyone know how to make a larger window and populate it with the <code>edit_traits(kind='subpanel')</code> UI objects from a couple traited objects? I found an example of doing this in a wx window here <a href="http://gael-varoquaux.info/computers/traits_tutorial/slides_Traits_en.pdf" rel="nofollow noreferrer">http://gael-varoquaux.info/computers/traits_tutorial/slides_Traits_en.pdf</a> on slide 23, is there a way to do this that does not tie me to wxPython?</p>
  
  <p>An answer here will likely also answer a similar question (<a href="https://stackoverflow.com/questions/15143705/traitsui-sharing-an-object">TraitsUI, sharing an object</a>) </p>
