Grabbing a part of a window as an image

Is it possible to Grab a part of a window as an image? I would like (from
within wxPython) to grab a part of a wxWindow as an image. This would help
me in dragging column headers etc. around on the screen.

Any help would be appreciated.

Regards
Gerrit

This code is from the widgets sample in PythonCard
(PythonCardPrototype\samples\widgets\widgets.py) which uses something like
you describe to automatically build images for documentation of each widget
(control/component).

  # w is the window you want to copy from
  # ignore the file saving bit if you don't need it
  bmp = wx.wxEmptyBitmap(w.size[0], w.size[1])
  memdc = wx.wxMemoryDC()
  memdc.SelectObject(bmp)
  dc = wx.wxWindowDC(w)
  memdc.Blit(0, 0, w.size[0], w.size[1], dc, 0, 0)
  imgfilename = os.path.join('documentation', 'images', name + '.png')
  bmp.SaveFile(imgfilename, wx.wxBITMAP_TYPE_PNG)
  dc = None
  memdc.SelectObject(wx.wxNullBitmap)
  memdc = None
  bmp = None
