form_win(3X) form_win(3X)
form_win - make and break form window and subwindow associations
#include <form.h>
int set_form_win(FORM *form, WINDOW *win);
WINDOW *form_win(const FORM *form);
int set_form_sub(FORM *form, WINDOW *sub);
WINDOW *form_sub(const FORM *form);
int scale_form(const FORM *form, int *rows, int *columns);
Every form has an associated pair of curses windows. The form
window displays any title and border associated with the window;
the form subwindow displays the items of the form that are
currently available for selection.
The first four functions get and set those windows. It is not
necessary to set either window; by default, the driver code uses
stdscr for both.
In the set_ functions, window argument of NULL is treated as
though it were stsdcr. A form argument of NULL is treated as a
request to change the system default form window or subwindow.
The function scale_form returns the minimum size required for the
subwindow of form.
Routines that return pointers return NULL on error. Routines
that return an integer return one of the following error codes:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno(3)).
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_POSTED
The form has already been posted.
E_NOT_CONNECTED
No items are connected to the form.
curses(3X), curs_variables(3X), form(3X).
The header file <form.h> automatically includes the header file
<curses.h>.
These routines emulate the System V forms library. They were not
supported on Version 7 or BSD versions.
