#
# o Updated for wx namespace
#
# 11/26/2003 - Jeff Grimmett ([email protected])
#
# o Ugh. AFter updating to the Bind() method, things lock up
# on various control clicks. Will have to debug. Only seems
# to happen on windows with calendar controls, though.
#
# 11/30/2003 - Jeff Grimmett ([email protected])
#
# o Lockup issue clarification: it appears that the spinner is
# the culprit.

This control provides a Calendar control class for displaying and selecting dates.
In addition, the class is extended and can be used for printing/previewing.
Additional features include weekend highlighting and business type Monday-Sunday
format.
See example for various methods used to set display month, year, and highlighted
dates (different font and background colours).
