#
# o Updated for wx namespace
# o Tested with updated demo
# o Added new event type EVT_CALENDAR. The reason for this is that the original
#   library used a hardcoded ID of 2100 for generating events. This makes it
#   very difficult to fathom when trying to decode the code since there's no
#   published API. Creating the new event binder might seem like overkill - 
#   after all, you might ask, why not just use a new event ID and be done with
#   it? However, a consistent interface is very useful at times; also it makes
#   it clear that we're not just hunting for mouse clicks -- we're hunting
#   wabbit^H^H^H^H (sorry bout that) for calender-driven mouse clicks. So
#   that's my sad story. Shoot me if you must :-)
# o There's still one deprecation warning buried in here somewhere, but I 
#   haven't been able to find it yet. It only occurs when displaying a 
#   print preview, and only the first time. It *could* be an error in the
#   demo, I suppose.
#
#   Here's the traceback:
#
#   C:\Python\lib\site-packages\wx\core.py:949: DeprecationWarning: 
#       integer argument expected, got float
