"""
ActiveXControl sample usage.

Based on original code by Willy Heineman, wheineman@uconect.net, 14 February 2000

ActiveXControl provides a simplified wrapper for creating activeX
controls within wxPython GUIs.  It allows you to include the activeX
control in a sizer, and includes a flag to prevent redrawing the
background behind the control (reduces the annoying flicker on
Win32 systems).
