.SH DESCRIPTION
The Cdk calendar widget creates a pop-up calendar. The calendar widget allows
the user to traverse through months/years using the cursor keys.

.SH AVAILABLE FUNCTIONS
CDKCALENDAR *newCDKCalendar (CDKSCREEN *\f2screen\f1, int \f2xpos\f1, int \f2ypos\f1, char *\f2title\f1, int \f2day\f1, int \f2month\f1, int \f2year\f1, chtype \f2dayAttrib\f1, chtype \f2monthAttrib\f1, chtype \f2yearAttrib\f1, chtype \f2highlight\f1, boolean \f2box\f1, boolean \f2shadow\f1);
.RS 3
This function creates a pointer to a calendar widget. The \f2screen\f1 
parameter is the screen you wish this widget to be placed in. The parameter 
\f2xpos\f1 controls the placement of the object along the horizontal axis. 
This parameter can take integer value or one of the pre-defined values of 
\f4LEFT\f1, \f4RIGHT\f1, and \f4CENTER\f1. The parameter \f2ypos\f1 controls 
the placement of the object along the vertical axis. This parameter can accept
an integer value or a pre-defined value of \f4TOP\f1, \f4BOTTOM\f1, and 
\f4CENTER\f1. The \f2title\f1 parameter is the string which will be displayed 
at the top of the widget. The title can be more than one line; just 
provide a carriage return character at the line break. The parameters \f2year\f1,
\f2month\f1, and \f2day\f1 set the initial date of the calendar. The three 
parameters following \f2yearAttrib\f1, \f2monthAttrib\f1, and \f2dayAttrib\f1 
represent the attributes of the year, month, and day respectfully. The 
\f2highlight\f1 parameter sets the highlight of the currently selected day. 
The \f2box\f1 parameter states whether the widget will be drawn with a box 
around it or not. The \f2shadow\f1 parameter accepts a boolean value to turn 
the shadow on or off around this widget. If the widget could not be created 
then a \f4NULL\f1 pointer is returned.
.RE

time_t activateCDKCalendar (CDKCALENDAR *\f2calendar\f1, chtype *\f2actions\f1);
.RS 3
This function activates the calendar widget and lets the user interact with the
widget. The \f2calendar\f1 widget is a pointer to a non-NULL calendar widget.
If the \f2actions\f1 parameter is passed with a non-NULL value, the characters
in the array will be injected into the widget. To activate the widget
interactively pass in a \f4NULL\f1 pointer for \f2actions\f1. If the character 
entered into this widget is \f4RETURN\f1 then this function will return a type
of \f4time_t\f1. The \f4time_t\f1 type is used in the functions defined in the
time.h header file. (do a man on \f4localtime\f1 or \f4ctime\f1 for more 
information). If the character entered into this widget was \f4ESCAPE\f1 or
\f4TAB\f1 then this function will return a value of (time_t)-1 and the structure
member \f4exitType\f1 will be set to \f4vESCAPE_HIT\f1.
.RE

time_t injectCDKCalendar (CDKCALENDAR *\f2calendar\f1, chtype \f2character\f1);
.RS 3
This function injects a single character into the widget. The parameter 
\f2calendar\f1 is a pointer to a non-NULL calendar widget. The parameter 
\f2character\f1 is the character to inject into the widget. If the character 
entered into this widget is \f4RETURN\f1 then this function will return a type
of \f4time_t\f1. The \f4time_t\f1 type is used in the functions defined in the
time.h header file. (do a man on \f4localtime\f1 or \f4ctime\f1 for more 
information). If the character entered into this widget was \f4ESCAPE\f1 or
\f4TAB\f1 then this function will return a value of (time_t)-1 and the structure
member \f4exitType\f1 will be set to \f4vESCAPE_HIT\f1. Any other character
injected into the widget will set the structure member \f4exitType\f1 to
\f4vEARLY_EXIT\f1 and the function will return (time_t)-1.
.RE

void setCDKCalendar (CDKCALENDAR *\f2calendar\f1, int \f2day\f1, int \f2month\f1, int \f2year\f1, chtype \f2dayAttrib\f1, chtype \f2monthAttrib\f1, chtype \f2yearAttrib\f1, chtype \f2highlight\f1, boolean \f2box\f1);
.RS 3
This function lets the programmer modify certain elements of an already defined
calendar widget. The \f2calendar\f1 parameter represents an already defined calendar
pointer. The other parameter names correspond to the same parameter names listed 
in the \f4newCDKCalendar\f1 function.
.RE 

void setCDKCalendarDate (CDKCALENDAR *\f2calendar\f1, int \f2day\f1, int \f2month\f1, int \f2year\f1);

This sets the current date the calendar displays.
.RE 

void getCDKCalendarDate (CDKCALENDAR *\f2calendar\f1, int *\f2day\f1, int *\f2month\f1, int *\f2year\f1);
.RS 3
This returns the current date the calendar is displaying.
.RE 

void setCDKCalendarDayAttribute (CDKCALENDAR *\f2calendar\f1, chtype \f2attribute\f1);
.RS 3
This sets the attribute of the day in the calendar.
.RE 

chtype getCDKCalendarDayAttribute (CDKCALENDAR *\f2calendar\f1);
.RS 3
This returns the attribute of the day attribute of the calendar.
.RE

.RS 3
This sets the attribute of the month in the calendar.
.RE 

chtype getCDKCalendarMonthAttribute (CDKCALENDAR *\f2calendar\f1);
.RS 3
This returns the attribute of the month attribute of the calendar.
.RE 

void setCDKCalendarYearAttribute (CDKCALENDAR *\f2calendar\f1, chtype \f2attribute\f1);
.RS 3
This sets the attribute of the year in the calendar.
.RE 

chtype getCDKCalendarYearAttribute (CDKCALENDAR *\f2calendar\f1);
.RS 3
This returns the attribute of the year attribute of the calendar.
.RE 

void setCDKCalendarHighlight (CDKCALENDAR *\f2calendar\f1, chtype \f2highlight\f1);
.RS 3
This function sets the attribute of the highlight bar of the scrolling
list portion of the widget.
.RE

chtype getCDKCalendarHighlight (CDKCALENDAR *\f2calendar\f1);
.RS 3
This returns the attribute of the highlight bar of the scrolling
list portion of the widget.
.RE

void setCDKCalendarBox (CDKCALENDAR *\f2calendar\f1, boolean \f2boxWidget\f1);
.RS 3
This sets whether or not the widget will be draw with a box around it.
.RE

boolean getCDKCalendarBox (CDKCALENDAR *\f2calendar\f1);
.RS 3
This returns whether or not the widget will be drawn with a box around it.
.RE

void setCDKCalendarMarker (CDKCALENDAR *\f2calendar\f1, int \f2day\f1, int \f2month\f1, int \f2year\f1, chtype \f2marker\f1);
.RS 3
This allows the user to set a marker which will be displayed when the month is
drawn. The \f2marker\f1 parameter is the attribute to use when drawing the 
marker. If more than one marker is set on a single day, then the day will blink
with the original marker attribute.
.RE 

void removeCDKCalendarMarker (CDKCALENDAR *\f2calendar\f1, int \f2day\f1, int \f2month\f1, int \f2year\f1);
.RS 3
This function removes a marker from the calendar.
.RE 

void setCDKCalendarDate (CDKCALENDAR *\f2calendar\f1, int \f2day\f1, int \f2month\f1, int \f2year\f1);
.RS 3
This function sets the calendar to the given date. If the value of the \f2day\f1,
\f2month\f1, or \f2year\f1 parameters is -1 then the current day, month, or year
is used to set the date.
.RE 

void moveCDKCalendar (CDKCALENDAR *\f2calendar\f1, int \f2xpos\f1, int \f2ypos\f1, boolean \f2relative\f1, boolean \f2refresh\f1);
.RS 3
This function moves the given widget to the given position. The parameters
\f2xpos\f1 and \f2ypos\f1 is the new position of the widget. The parameter
\f2xpos\f1 can accept an integer value or one of the pre-defined values of
\f4TOP\f1, \f4BOTTOM\f1, and \f4CENTER\f1. The parameter \f2ypos\f1 can 
accept an integer value or one of the pre-defined values of \f4LEFT\f1,
\f4RIGHT\f1, and \f4CENTER\f1. The parameter \f2relative\f1 states whether
the \f2xpos\f1/\f2ypos\f1 pair is a relative move or an absolute move. For
example if \f2xpos\f1 = 1 and \f2ypos\f1 = 2 and \f2relative\f1 = \f2TRUE\f1,
then the widget would move one row down and two columns right. If the value
of \f2relative\f1 was \f2FALSE\f1 then the widget would move to the position
(1,2). Do not use the values of \f4TOP\f1, \f4BOTTOM\f1, \f4LEFT\f1, 
\f4RIGHT\f1, or \f4CENTER\f1 when \f2relative\f1 = \f4TRUE\f1. (wierd things
may happen). The final parameter \f2refresh\f1 is a boolean value which 
states whether the widget will get refreshed after the move or not.
.RE
