|
|
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.

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.

|

This function lets the programmer modify certain elements of an already defined
|

calendar widget. The \f2calendar\f1 parameter represents an already defined calendar

in the \f4newCDKCalendar\f1 function.

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. (weird 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.
