title: get pixel position of pointer
body: <p>Is it possible to get the cursor position in pixel value, using the standard Python libraries?</p>
  
  <p>I can not properly position the popup menu:   </p>
  
  <pre><code>    pos = self.text.GetLastPosition()
      start, end = self.text.PositionToXY(pos)
  
      self.text.PopupMenuXY(self.popupmenu,start, end)
  </code></pre>
  
  <p>Thanks!</p>
