.SH DESCRIPTION
|
|
The Cdk buttonbox widget creates a buttonbox box with a message and a varied number of
|
|
buttons to choose from. The following are functions which create or manipulate
|
|
the Cdk buttonbox box widget.

CDKBUTTONBOX *newCDKButtonbox (CDKSCREEN *\f2screen\f1, int \f2xpos\f1, int \f2ypos\f1, char **\f2title\f1 , int \f2rows\f1, int \f2cols\f1, char **\f2buttons\f1, int \f2buttonCount\f1, chtype \f2highLight\f1, boolean \f2box\f1, boolean \f2shadow\f1);
|
|
.RS 3
|
|
This function creates a pointer to a buttonbox 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
|
|
accepts 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 \f2height\f1 and \f2width\f1 parameters control the height and width of the
|
|
widget. The parameter \f2title\f1 is the title of the widget. The \f2rows\f1
|
|
parameter states how many rows of buttons there will be; \f2\cols\f1 sets the number
|
|
of columns. The \f2buttons\f1 array contains a list of all the buttons; while
|
|
\f2buttonCount\f1 is the number of elements in the \f2button\f1 array.
|
|
\f2highlight\f1 is the attribute of the currently highlighted button. 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.

int activateCDKButtonbox (CDKBUTTONBOX *\f2buttonbox\f1, chtype *\f2actions\f1);
|
|
.RS 3
|
|
This function activates the buttonbox widget and lets the user interact with the
|
|
widget. The parameter \f2buttonbox\f1 is a pointer to a non-NULL buttonbox 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
|
|
value from 0 to the number of buttons -1, representing the button selected. It
|
|
will also set the structure member \f4exitType\f1 to \f4vNORMAL\f1. If the
|
|
character entered into this widget was \f4ESCAPE\f1 then the widget will return
|
|
a value of -1 and the structure member \f4exitType\f1 will be set to
|
|
\f4vESCAPE_HIT\f1.

.RE
|
|
|
|
int injectCDKButtonbox (CDKBUTTONBOX *\f2buttonbox\f1, chtype \f2character\f1);
|
|
.RS 3
|
|
This function injects a single character into the widget. The parameter
|
|
\f2buttonbox\f1 is a pointer to a non-NULL buttonbox widget. The parameter
|
|
\f2character\f1 is the character to inject into the widget. If the character
|
|
injected into this widget was \f4RETURN\f1 then the character injected into
|
|
this widget is \f4RETURN\f1 or \f4TAB\f1 then this function will return a
|
|
value from 0 to the number of buttons -1, representing the button selected. It
|
|
will also set the structure member \f4exitType\f1 to \f4vNORMAL\f1. If the
|
|
character entered into this widget was \f4ESCAPE\f1 then the widget will return
|
|
a value of -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 -1.

|

.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. (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.
