43 : Description
44 : ============
45 :
46 : class Calendar
47 :
48 : This class allows for the selection of a date. The displayed date range is
49 : the one specified by the Date class. We display as many months as we have
50 : space in the control. The user can switch between months using a ContextMenu
51 : (clicking on the month's name) or via two ScrollButtons in-between the months.
52 :
53 : --------------------------------------------------------------------------
54 :
55 : WinBits
56 :
57 : WB_BORDER We draw a border around the window.
58 : WB_TABSTOP Keyboard control is possible. We get the focus, when
59 : the user clicks in the Control.
60 : WB_QUICKHELPSHOWSDATEINFO Show DateInfo as BallonHelp even if QuickInfo is enabled
61 : WB_BOLDTEXT We format by bold texts and DIB_BOLD is evaluated by
62 : AddDateInfo()
63 : WB_FRAMEINFO We format in a way, so that FrameInfo can be displayed
64 : and the FrameColor is evaluated by AddDateInfo()
65 : WB_RANGESELECT The user can select multiple days, which need to be
66 : consecutive
67 : WB_MULTISELECT The user can select multiple days
68 : WB_WEEKNUMBER We also display the weekdays
69 :
70 : --------------------------------------------------------------------------
71 :
72 : We set and get the selected date by SetCurDate()/GetCurDate().
73 : If the user selects a date Select() is called. If the user double clicks
74 : DoubleClick() is called.
75 :
76 : --------------------------------------------------------------------------
77 :
78 : CalcWindowSizePixel() calculates the window size in pixel that is needed
79 : to display a certain number of months.
80 :
81 : --------------------------------------------------------------------------
82 :
83 : SetSaturdayColor() and SetSundayColor() set a special color for Saturdays
84 : and Sundays.
85 : AddDateInfo() marks special days. With that we can set e.g. public holidays
86 : to another color or encircle them (for e.g. appointments).
87 : If we do not supply a year in the date, the day is used in EVERY year.
88 :
89 : AddDateInfo() can also add text for every date, which is displayed if the
90 : BalloonHelp is enabled.
91 : In order to not have to supply all years with the relevant data, we call
92 : the RequestDateInfo() handler if a new year is displayed. We can then query
93 : the year in the handler with GetRequestYear().
94 :
95 : --------------------------------------------------------------------------
96 :
97 : In order to display a ContextMenu for a date, we need to override the
98 : Command handler. GetDate() can infer the date from the mouse's position.
99 : If we use the keyboard, the current date should be use.
100 :
101 : If a ContextMenu is displayed, the baseclass' handler must not be called.
102 :
103 : --------------------------------------------------------------------------
104 :
105 : For multiple selection (WB_RANGESELECT or WB_MULTISELECT) SelectDate(),
106 : SelectDateRange() can select date ranges. SelectDateRange() selects
107 : including the end date.
108 : SetNoSelection() deselects everything.
109 : SetCurDate() does not select the current date, but only defines the focus
110 : rectangle.
111 : GetSelectDateCount()/GetSelectDate() query the selected range.
112 : IsDateSelected() queries for the status of a date.
113 :
114 : The SelectionChanging() handler is being called while a user selects a
115 : date. In it, we can change the selected range. E.g. if we want to limit
116 : or extend the selected range. The selected range is realised via SelectDate()
117 : and SelectDateRange() and queried with GetSelectDateCount()/GetSelectDate().
118 :
119 : IsSelectLeft() returns the direction of the selection:
120 : sal_True is a selection to the left or up
121 : sal_False is a selection to the right or down
122 :
123 : --------------------------------------------------------------------------
124 :
125 : If the DateRange area changes and we want to take over the selection, we
126 : should only do this is if IsScrollDateRangeChanged() retruns sal_True.
127 : This method returns sal_True if the area change was triggered by using the
128 : ScrollButtons and sal_False if it was triggered by Resize(), other method
129 : calls or by ending a selection.

374 : The preferences for the CalendarControl can be set via SetCalendarStyle().
375 :
376 : --------------------------------------------------------------------------
377 :
378 : With EnableToday()/EnableNone() we can enable a TodayButton and a NoneButton.
379 :
380 : --------------------------------------------------------------------------
381 :
382 : If we set WB_RANGESELECT with SetCalendarStyle(), we can select multiple days
383 : in the Calendar.
384 :
385 : Because we only take over the start date into the field, we should query
386 : with GetCalendar() in the SelectHandler and with GetSelectDateCount()/GetSelectDate()
387 : the selected range. We then can e.g. take over that value to another field.
388 :
389 : --------------------------------------------------------------------------
390 :
391 : If a derived Calendar should be used, we can override the CreateCalendar()
392 : method in CalendarField and create an own calendar there ourselves.
