The calendar control allows the user to pick a date.
The user can move the current selection using the keyboard and select the date
(generating EVT_CALENDAR event) by pressing <Return> or double clicking it.
Generic calendar has advanced possibilities for the customization of its display,
described below. If you want to use these possibilities on every platform, use
wxGenericCalendarCtrl instead of wxCalendarCtrl.
All global settings (such as colours and fonts used) can, of course, be changed. But
also, the display style for each day in the month can be set independently using wxCalendarDateAttr
class.
An item without custom attributes is drawn with the default colours and font and without
border, but setting custom attributes with setAttr/3 allows modifying its appearance. Just create a
custom attribute object and set it for the day you want to be displayed specially (note
that the control will take ownership of the pointer, i.e. it will delete it itself). A day
may be marked as being a holiday, even if it is not recognized as one by wx_datetime() using the wxCalendarDateAttr:setHoliday/2 method.
As the attributes are specified for each day, they may change when the month is changed,
so you will often want to update them in EVT_CALENDAR_PAGE_CHANGED event handler.
If neither the wxCAL_SUNDAY_FIRST or wxCAL_MONDAY_FIRST style is given, the first day
of the week is determined from operating system's settings, if possible. The native wxGTK
calendar chooses the first weekday based on locale, and these styles have no effect on it.
Styles
This class supports the following styles:
wxCAL_SUNDAY_FIRST: Show Sunday as the first day in the week (not in wxGTK)
wxCAL_MONDAY_FIRST: Show Monday as the first day in the week (not in wxGTK)
wxCAL_SHOW_HOLIDAYS: Highlight holidays in the calendar (only generic)
wxCAL_NO_YEAR_CHANGE: Disable the year changing (deprecated, only generic)
wxCAL_NO_MONTH_CHANGE: Disable the month (and, implicitly, the year) changing
wxCAL_SHOW_SURROUNDING_WEEKS: Show the neighbouring weeks in the previous and next months (only generic, always on for the native controls)
wxCAL_SEQUENTIAL_MONTH_SELECTION: Use alternative, more compact, style for the month and year selection controls. (only generic)
wxCAL_SHOW_WEEK_NUMBERS: Show week numbers on the left side of the calendar. (not in generic)

Types
-type wxCalendarCtrl() :: wx:wx_object().
Functions
-spec create(This, Parent, Id) -> boolean() when This :: wxCalendarCtrl(), Parent :: wxWindow:wxWindow(), Id :: integer().
-spec create(This, Parent, Id, [Option]) -> boolean() when This :: wxCalendarCtrl(), Parent :: wxWindow:wxWindow(), Id :: integer(), Option :: {date, wx:wx_datetime()} | {pos, {X :: integer(), Y :: integer()}} | {size, {W :: integer(), H :: integer()}} | {style, integer()}.
Creates the control.
See wxWindow:new/3 for the meaning of the parameters and the control overview for the possible styles.
destroy(This :: wxCalendarCtrl()) -> ok
Destroys the object
-spec enableHolidayDisplay(This) -> ok when This :: wxCalendarCtrl().
-spec enableHolidayDisplay(This, [Option]) -> ok when This :: wxCalendarCtrl(), Option :: {display, boolean()}.
This function should be used instead of changing wxCAL\_SHOW\_HOLIDAYS style bit
directly.
It enables or disables the special highlighting of the holidays.
-spec enableMonthChange(This) -> boolean() when This :: wxCalendarCtrl().
-spec enableMonthChange(This, [Option]) -> boolean() when This :: wxCalendarCtrl(), Option :: {enable, boolean()}.
This function should be used instead of changing wxCAL\_NO\_MONTH\_CHANGE style bit.
It allows or disallows the user to change the month interactively. Note that if the month cannot be changed, the year cannot be changed neither.
Return: true if the value of this option really changed or false if it was already set to the requested value.
-spec enableYearChange(This) -> ok when This :: wxCalendarCtrl().
-spec enableYearChange(This, [Option]) -> ok when This :: wxCalendarCtrl(), Option :: {enable, boolean()}.
Deprecated:
This function should be used instead of changing wxCAL_NO_YEAR_CHANGE style bit
directly. It allows or disallows the user to change the year interactively. Only in
generic wxCalendarCtrl.
Returns the attribute for the given date (should be in the range 1...31).
The returned pointer may be NULL. Only in generic wxCalendarCtrl.
getDate(This :: wxCalendarCtrl()) -> wx:wx_datetime()
Gets the currently selected date.
getHeaderColourBg(This :: wxCalendarCtrl()) -> wx:wx_colour4()
Gets the background colour of the header part of the calendar window.
This method is currently only implemented in generic wxCalendarCtrl and always
returns wxNullColour in the native versions.
See: setHeaderColours/3
getHeaderColourFg(This :: wxCalendarCtrl()) -> wx:wx_colour4()
Gets the foreground colour of the header part of the calendar window.
This method is currently only implemented in generic wxCalendarCtrl and always
returns wxNullColour in the native versions.

getHolidayColourBg(This :: wxCalendarCtrl()) -> wx:wx_colour4()

holidays display at all and always return wxNullColour.
See: setHolidayColours/3

Types
