.SH DESCRIPTION
The Cdk template widget creates a template widget which allows a user to type 
information into an entry field with a pre-set field format. Typical uses for
this widget would be a date field or a time field. The following are functions
which create or manipulate the Cdk template box widget.

.SH AVAILABLE FUNCTIONS
CDKTEMPLATE *newCDKTemplate (CDKSCREEN *\f2screen\f1, int \f2xpos\f1, int \f2ypos\f1, char *\f2title\f1, char *\f2label\f1, char *\f2plate\f1, char *\f2overlay\f1, boolean \f2box\f1, boolean \f2shadow\f1);
.RS 3
This function creates a pointer to a template 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 accept an 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 one of the pre-defined values 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 \f2label\f1 parameter is the 
string which will be displayed in the label of the template field. The 
\f2plate\f1 parameter defines what character is allowed at what position 
in the template field. This is done by creating a character plate by using 
special format character to tell the template widget what type of character 
is allowed where in the template widget.  The following table lists all of
the current format types.
.LP
.nf 
.RS 3
\f2Plate_Character   Effect\f1
#                 Accepts an integer value.
A                 Accepts an alphabetic value.
C                 Accepts an alphabetic value. Automatically
                  converts the character to upper case.
c                 Accepts an alphabetic value. Automatically
                  converts the character to lower case.
M                 Accepts alphanumeric characters.
X                 Accepts alphanumeric characters. Automatically
                  converts the character to upper case.
x                 Accepts alphanumeric characters. Automatically
                  converts the character to upper case.
Anything else     Ignored and assumed a non-editable position.

The \f2overlay\f1 parameter is the overlay of the template field. If the field
needed some sort of overlay, this parameter supplies this. A date field could
have YY/MM/DD, the overlay parameter would display YY/MM/DD on an empty template
field.  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. 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

char *activateCDKTemplate (CDKTEMPLATE *\f2template\f1, chtype *\f2actions\f1);
.RS 3
This function activates the template widget and lets the user interact with the
widget. The parameter \f2template\f1 is a pointer to a non-NULL template 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 or \f4TAB\f1 then this function will return 
a \f4char *\f1 representing the information typed into the widget and the 
structure member \f4exitType\f1 will be set to \f4vNORMAL\f1. If the character
entered was \f4ESCAPE\f1 then the function will returns \f4NULL\f1 pointer and 
the structure member \f4exitType\f1 is set to \f4vESCAPE_HIT\f1.
.RE

char *injectCDKTemplate (CDKTEMPLATE *\f2template\f1, chtype \f2character\f1);
.RS 3
This function injects a single character into the widget. The parameter 
\f2template\f1 is a pointer to a non-NULL template. The parameter 
\f2character\f1 is the character to inject into the widget. If the character 
injected into this widget was \f4RETURN\f1 or \f4TAB\f1 then this function will
return a \f4char *\f1 representing the information typed into the widget and the 
structure member \f4exitType\f1 will be set to \f4vNORMAL\f1. If the character
entered was \f4ESCAPE\f1 then the function will returns \f4NULL\f1 pointer and 
the structure member \f4exitType\f1 is 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 a \f4NULL\f1 pointer.
.RE

void setCDKTemplate (CDKTEMPLATE *\f2template\f1, char *\f2value\f1, boolean \f2box\f1);

.RE

void moveCDKTemplate (CDKTEMPLATE *\f2template\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.
