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.
AVAILABLE FUNCTIONS
CDKTEMPLATE *newCDKTemplate (CDKSCREEN *screen, int xpos, int ypos,
char *title, char *label, char *plate, char *overlay, boolean box,
boolean shadow);
This function creates a pointer to a template widget. The screen
parameter is the screen you wish this widget to be placed in. The
parameter xpos controls the placement of the object along the hori-
zontal axis. This parameter can accept an integer value or one of
the pre-defined values of LEFT, RIGHT, and CENTER. The parameter
ypos 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 TOP, BOTTOM, and CENTER. The title 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 label parameter is the string which will be
displayed in the label of the template field. The plate 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.
Plate_Character Effect
# 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 overlay 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 box parameter states
whether the widget will be drawn with a box around it or not. The
shadow parameter accepts a boolean value to turn the shadow on or
off around this widget. The box parameter states whether the widget
will be drawn with a box around it or not. The shadow parameter
accepts a boolean value to turn the shadow on or off around this
widget. If the widget could not be created then a NULL pointer is
returned.
char *activateCDKTemplate (CDKTEMPLATE *template, chtype *actions);
This function activates the template widget and lets the user inter-
act with the widget. The parameter template is a pointer to a non-
NULL template widget. If the actions 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 NULL
pointer for actions. If the character entered into this widget is
RETURN or TAB then this function will return a char * representing
the information typed into the widget and the structure member exit-
Type will be set to vNORMAL. If the character entered was ESCAPE
then the function will returns NULL pointer and the structure member
exitType is set to vESCAPE_HIT.
char *injectCDKTemplate (CDKTEMPLATE *template, chtype character);
This function injects a single character into the widget. The param-
eter template is a pointer to a non-NULL template. The parameter
character is the character to inject into the widget. If the charac-
ter injected into this widget was RETURN or TAB then this function
will return a char * representing the information typed into the
widget and the structure member exitType will be set to vNORMAL. If
the character entered was ESCAPE then the function will returns NULL
pointer and the structure member exitType is set to vESCAPE_HIT. Any
other character injected into the widget will set the structure mem-
ber exitType to vEARLY_EXIT and the function will return a NULL
pointer.
void setCDKTemplate (CDKTEMPLATE *template, char *value, boolean box);
This function lets the programmer modify certain elements of an
already defined template widget. The parameter names correspond to
the same parameter names listed in the newCDKTemplate function.
void setCDKTemplateValue (CDKTEMPLATE *template, char *value);
This sets the value in the widget.
char *getCDKTemplateValue (CDKTEMPLATE *template);
This returns the current value of the widget.
void setCDKTemplateMin (CDKTEMPLATE *template, int min);
This sets the minimum number of characters that have to be entered
before the widget will exit.
int getCDKTemplateMin (CDKTEMPLATE *template);
This returns the minimum characters that have to be entered before
the widget will exit.
void setCDKTemplateBox (CDKTEMPLATE *template, boolean Box);
This sets whether or not the widget will be draw with a box around
it.
boolean getCDKTemplateBox (CDKTEMPLATE *template);
This returns whether or not the widget will be drawn with a box
around it.
void setCDKTemplateULChar (CDKTEMPLATE *template, chtype character);
This function sets the upper left hand corner of the widgets box to
the given character.
void setCDKTemplateURChar (CDKTEMPLATE *template, chtype character);
This function sets the upper right hand corner of the widgets box to
the given character.
void setCDKTemplateLLChar (CDKTEMPLATE *template, chtype character);
This function sets the lower left hand corner of the widgets box to
the given character.
void setCDKTemplateLRChar (CDKTEMPLATE *template, chtype character);
This function sets the lower right hand corner of the widgets box to
the given character.
void setCDKTemplateVerticalChar (CDKTEMPLATE *template, chtype charac-
ter);
This function sets the vertical drawing character for the box to the
given character.
void setCDKTemplateHorizontalChar (CDKTEMPLATE *template, chtype char-
acter);
This function sets the horizontal drawing character for the box to
the given character.
void setCDKTemplateBoxAttribute (CDKTEMPLATE *template, chtype
attribute);
This function sets the attribute of the box.
void setCDKTemplateBackgroundColor (CDKTEMPLATE *template, char
*color);
This sets the background color of the widget. The parameter color is
in the format of the Cdk format strings. To get more information
look at the cdk_display manual page.
void setCDKTemplateCB (CDKTEMPLATE *template, TEMPLATECB callbackFunc-
tion);
This function allows the programmer to set a different widget input
handler. The parameter callbackFunction is of type TEMPLATECB. The
current default function is CDKTemplateCallBack.
void moveCDKTemplate (CDKTEMPLATE *template, int xpos, int ypos,
boolean relative, boolean refresh);
This function moves the given widget to the given position. The
parameters xpos and ypos is the new position of the widget. The
parameter xpos can accept an integer value or one of the pre-defined
values of TOP, BOTTOM, and CENTER. The parameter ypos can accept an
integer value or one of the pre-defined values of LEFT, RIGHT, and
CENTER. The parameter relative states whether the xpos/ypos pair is
a relative move or an absolute move. For example if xpos = 1 and
ypos = 2 and relative = TRUE, then the widget would move one row
down and two columns right. If the value of relative was FALSE then
the widget would move to the position (1,2). Do not use the values
of TOP, BOTTOM, LEFT, RIGHT, or CENTER when relative = TRUE. (weird
things may happen). The final parameter refresh is a boolean value
which states whether the widget will get refreshed after the move or
not.
void positionCDKTemplate (CDKTEMPLATE *template);
This function allows the user to move the widget around the screen
via the cursor/keypad keys. The following key bindings can be used
to move the widget around the screen.
Key Bindings

The widgetType parameter is a defined type which states what
Cdk object type is being used. To learn more about the type
EObjectType read the cdk_binding manual page. The object
parameter is the pointer to the widget object. The key is the
character to bind. The function is the function type. To learn
more about the key binding callback function types read the
cdk_binding manual page. The last parameter data is a pointer
to any data that needs to get passed to the callback function.
KEY BINDINGS
