#----------------------------------------------------------------------------
# Name: calendar.py
# Purpose: Calendar display control
#
# Author: Lorne White (email: lorne.white@telusplanet.net)
#
# Created:
# Version 0.92
# Date: Nov 26, 2001
# Licence: wxWindows license
#----------------------------------------------------------------------------
# 12/01/2003 - Jeff Grimmett (grimmtooth@softhome.net)
#
# 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
# newobj = _core.new_Rect(*args, **kwargs)
#
# 12/17/2003 - Jeff Grimmett (grimmtooth@softhome.net)
#
# o A few style-guide nips and tucks
# o Renamed wxCalendar to Calendar
# o Couple of bugfixes
#
# 06/02/2004 - Joerg "Adi" Sieker adi@sieker.info
#
# o Changed color handling, use dictionary instead of members.
# This causes all color changes to be ignored if they manipluate the members directly.
# SetWeekColor and other method color methods were adapted to use the new dictionary.
# o Added COLOR_* constants
# o Added SetColor method for Calendar class
# o Added 3D look of week header
# o Added colors for 3D look of header
# o Fixed width calculation.
# Because of rounding difference the total width and height of the
# calendar could be up to 6 pixels to small. The last column and row
# are now wider/taller by the missing amount.
# o Added SetTextAlign method to wxCalendar. This exposes logic
# which was already there.
# o Fixed CalDraw.SetMarg which set set_x_st and set_y_st which don't get used anywhere.
# Instead set set_x_mrg and set_y_mrg
# o Changed default X and Y Margin to 0.
# o Added wxCalendar.SetMargin.
#
# 17/03/2004 - Joerg "Adi" Sieker adi@sieker.info
# o Added keyboard navigation to the control.
# Use the cursor keys to navigate through the ages. :)
# The Home key function as go to today
# o select day is now a filled rect instead of just an outline
#
# 15/04/2005 - Joe "shmengie" Brown joebrown@podiatryfl.com
# o Adjusted spin control size/placement (On Windows ctrls were overlapping).
# o Set Ok/Cancel buttons to wx.ID_OK & wx.ID_CANCEL to provide default dialog
# behaviour.
# o If no date has been clicked clicked, OnOk set the result to calend's date,
# important if keyboard only navigation is used.
#
# 12/10/2006 - Walter Barnes walter_barnes05@yahoo.com
# o Fixed CalDraw to properly render months that start on a Sunday.
#
# 21/10/2006 - Walter Barnes walter_barnes05@yahoo.com
# o Fixed a bug in Calendar: Shift and Control key status was only recorded for
# left-down events.
# o Added handlers for wxEVT_MIDDLE_DOWN and wxEVT_MIDDLE_DCLICK to generate
# EVT_CALENDAR for these mouse events.
