title: How to draw a transparent frame in wxpython
body: <p><strong>UPDATE</strong> I completely rephrased the question</p>
  <p>I want to create a window with round corners, that's also semi-transparent.</p>
  <p>I managed to make a frame semi-transparent by calling the <code>SetTransparent( alpha )</code> method, however, I still don't know how to make the window have no background.</p>
  <p>I tried to get the device context (dc) of the window and set the background brush to <code>wx.TRANSPARENT_BRUSH</code> but that doesn't seem to have any effect.</p>
  <p>I'm seeking a kind of effect similar to <a href="http://www.launchy.net/images/amarok.png" rel="nofollow noreferrer">this</a> for instance, but I want to do it without using a bitmap (i.e. without any external media file).</p>
  <p><strong>How do I set the background to nothing?</strong></p>
  <h3>Update:</h3>
  <p>it seems what I want is called &quot;shaped window&quot;. I'm looking a bit further into <em>that</em>, but still the question is: how can I make one without using any external media file (i.e. purely in code).</p>
