NAME
wxCalendarCtrl - Functions for wxCalendarCtrl class
DESCRIPTION
The calendar control allows the user to pick a date. The user can move
the current selection using the keyboard and select the date (generat-
ing 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 rec-
ognized as one by wx_datetime() using the wxCalendarDateAttr:setHoli-
day/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_CALEN-
DAR_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 set-
tings, 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:
Note: Changing the selected date will trigger an EVT_CALENDAR_DAY,
MONTH or YEAR event as well as an EVT_CALENDAR_SEL_CHANGED event.
See: Examples, wxCalendarDateAttr, wxCalendarEvent, wxDatePickerCtrl
This class is derived (and can use functions) from: wxControl wxWindow
wxEvtHandler

DATA TYPES
wxCalendarCtrl() = wx:wx_object()
EXPORTS
new() -> wxCalendarCtrl()
Default constructor.
new(Parent, Id) -> wxCalendarCtrl()
Types:
Parent = wxWindow:wxWindow()
Id = integer()
new(Parent, Id, Options :: [Option]) -> wxCalendarCtrl()
Types:
Parent = wxWindow:wxWindow()
Id = integer()
Option =
{date, wx:wx_datetime()} |
{pos, {X :: integer(), Y :: integer()}} |
{size, {W :: integer(), H :: integer()}} |
{style, integer()}
Does the same as create/4 method.
create(This, Parent, Id) -> boolean()
Types:
This = wxCalendarCtrl()
Parent = wxWindow:wxWindow()
Id = integer()
create(This, Parent, Id, Options :: [Option]) -> boolean()
Types:
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 control.
setDate(This, Date) -> boolean()
Types:
This = wxCalendarCtrl()
Date = wx:wx_datetime()
Sets the current date.
The date parameter must be valid and in the currently valid
range as set by SetDateRange() (not implemented in wx), other-
wise the current date is not changed and the function returns
false and, additionally, triggers an assertion failure if the
date is invalid.
getDate(This) -> wx:wx_datetime()
Types:
This = wxCalendarCtrl()
Gets the currently selected date.
enableYearChange(This) -> ok
Types:
This = wxCalendarCtrl()
enableYearChange(This, Options :: [Option]) -> ok
Types:
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.
enableMonthChange(This) -> boolean()
Types:
This = wxCalendarCtrl()
enableMonthChange(This, Options :: [Option]) -> boolean()
Types:
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 interac-
tively. Note that if the month cannot be changed, the year can-
not be changed neither.
Return: true if the value of this option really changed or false
if it was already set to the requested value.
enableHolidayDisplay(This) -> ok
Types:
This = wxCalendarCtrl()
enableHolidayDisplay(This, Options :: [Option]) -> ok
Types:
This = wxCalendarCtrl()
Option = {display, boolean()}
This function should be used instead of changing wxCAL_SHOW_HOL-
IDAYS style bit directly.
It enables or disables the special highlighting of the holidays.
setHeaderColours(This, ColFg, ColBg) -> ok
Types:
This = wxCalendarCtrl()
ColFg = ColBg = wx:wx_colour()
Set the colours used for painting the weekdays at the top of the
control.
This method is currently only implemented in generic wxCalen-
darCtrl and does nothing in the native versions.
getHeaderColourFg(This) -> wx:wx_colour4()
Types:
This = wxCalendarCtrl()
Gets the foreground colour of the header part of the calendar
window.
This method is currently only implemented in generic wxCalen-
darCtrl and always returns wxNullColour in the native versions.
See: setHeaderColours/3
getHeaderColourBg(This) -> wx:wx_colour4()
Types:
This = wxCalendarCtrl()
Gets the background colour of the header part of the calendar
window.
This method is currently only implemented in generic wxCalen-
darCtrl and always returns wxNullColour in the native versions.
See: setHeaderColours/3
setHighlightColours(This, ColFg, ColBg) -> ok
Types:
This = wxCalendarCtrl()
ColFg = ColBg = wx:wx_colour()
Set the colours to be used for highlighting the currently
selected date.
This method is currently only implemented in generic wxCalen-
darCtrl and does nothing in the native versions.
getHighlightColourFg(This) -> wx:wx_colour4()
Types:
This = wxCalendarCtrl()
Gets the foreground highlight colour.
Only in generic wxCalendarCtrl.
This method is currently only implemented in generic wxCalen-
darCtrl and always returns wxNullColour in the native versions.
See: setHighlightColours/3

Only in generic wxCalendarCtrl.
This method is currently only implemented in generic wxCalen-
darCtrl and always returns wxNullColour in the native versions.

setHolidayColours(This, ColFg, ColBg) -> ok
Types:
This = wxCalendarCtrl()
ColFg = ColBg = wx:wx_colour()
Sets the colours to be used for the holidays highlighting.
This method is only implemented in the generic version of the
control and does nothing in the native ones. It should also only
be called if the window style includes wxCAL_SHOW_HOLIDAYS flag
or enableHolidayDisplay/2 had been called.
getHolidayColourFg(This) -> wx:wx_colour4()
Types:
This = wxCalendarCtrl()
Return the foreground colour currently used for holiday high-
lighting.
Only useful with generic wxCalendarCtrl as native versions cur-
rently don't support holidays display at all and always return
wxNullColour.
See: setHolidayColours/3
getHolidayColourBg(This) -> wx:wx_colour4()
