  13 #
  14 # o Updated for wx namespace
  15 # o Tested with updated demo
  16 # o Added new event type EVT_CALENDAR. The reason for this is that the original
  17 #   library used a hardcoded ID of 2100 for generating events. This makes it
  18 #   very difficult to fathom when trying to decode the code since there's no
  19 #   published API. Creating the new event binder might seem like overkill -
  20 #   after all, you might ask, why not just use a new event ID and be done with
  21 #   it? However, a consistent interface is very useful at times; also it makes
  22 #   it clear that we're not just hunting for mouse clicks -- we're hunting
  23 #   wabbit^H^H^H^H (sorry bout that) for calender-driven mouse clicks. So
  24 #   that's my sad story. Shoot me if you must :-)
  25 # o There's still one deprecation warning buried in here somewhere, but I
  26 #   haven't been able to find it yet. It only occurs when displaying a
  27 #   print preview, and only the first time. It *could* be an error in the
  28 #   demo, I suppose.
  29 #
  30 #   Here's the traceback:
  31 #
  32 #   C:\Python\lib\site-packages\wx\core.py:949: DeprecationWarning:
  33 #       integer argument expected, got float
  34 #   newobj = _core.new_Rect(*args, **kwargs)

  37 #
  38 # o A few style-guide nips and tucks
  39 # o Renamed wxCalendar to Calendar
  40 # o Couple of bugfixes
  41 #
  42 # 06/02/2004 - Joerg "Adi" Sieker adi@sieker.info
  43 #
  44 # o Changed color handling, use dictionary instead of members.
  45 #   This causes all color changes to be ignored if they manipluate the members directly.
  46 #   SetWeekColor and other method color methods were adapted to use the new dictionary.
  47 # o Added COLOR_* constants
  48 # o Added SetColor method for Calendar class
  49 # o Added 3D look of week header
  50 # o Added colors for 3D look of header
  51 # o Fixed width calculation.
  52 #   Because of rounding difference the total width and height of the
  53 #   calendar could be up to 6 pixels to small. The last column and row
  54 #   are now wider/taller by the missing amount.
  55 # o Added SetTextAlign method to wxCalendar. This exposes logic
  56 #   which was already there.
  57 # o Fixed CalDraw.SetMarg which set set_x_st and set_y_st which don't get used anywhere.
  58 #   Instead set set_x_mrg and set_y_mrg
  59 # o Changed default X and Y Margin to 0.
  60 # o Added wxCalendar.SetMargin.
  61 #
  62 # 17/03/2004 - Joerg "Adi" Sieker adi@sieker.info
  63 # o Added keyboard navigation to the control.
  64 #   Use the cursor keys to navigate through the ages. :)
  65 #   The Home key function as go to today
  66 # o select day is now a filled rect instead of just an outline
  67 #
  68 # 15/04/2005 - Joe "shmengie" Brown joebrown@podiatryfl.com
  69 # o Adjusted spin control size/placement (On Windows ctrls were overlapping).
  70 # o Set Ok/Cancel buttons to wx.ID_OK & wx.ID_CANCEL to provide default dialog
  71 #   behaviour.
  72 # o If no date has been clicked clicked, OnOk set the result to calend's date,
  73 #   important if keyboard only navigation is used.
  74 #
  75 # 12/10/2006 - Walter Barnes walter_barnes05@yahoo.com
  76 # o Fixed CalDraw to properly render months that start on a Sunday.
  77 #
  78 # 21/10/2006 - Walter Barnes walter_barnes05@yahoo.com
  79 # o Fixed a bug in Calendar: Shift and Control key status was only recorded for
  80 #   left-down events.
  81 # o Added handlers for wxEVT_MIDDLE_DOWN and wxEVT_MIDDLE_DCLICK to generate
  82 #   EVT_CALENDAR for these mouse events.
