title: How to create a window with alpha-channel transparency, using wxPython?
body: <p>Hey there, first time asking.</p>
  
  <p>I have been trying to use wxPython to create an overlay windows to be displayed over other programs, however I can't seem to figure out how to make an image appear with an alpha-channel transparency over my desktop.</p>
  
  <p>In the future I will be planning to have buttons on top of the image also.</p>
  
  <p>Something like <a href="http://www.blog.pythonlibrary.org/2010/03/18/wxpython-putting-a-background-image-on-a-panel/" rel="nofollow">this</a>, but with an image that has an alpha so that you can see the window behind it.</p>
