NAME

6       form_win - make and break form window and subwindow associations
7

SYNOPSIS

9       #include <form.h>
10       int set_form_win(FORM *form, WINDOW *win);
11       WINDOW *form_win(const FORM *form);
12       int set_form_sub(FORM *form, WINDOW *sub);
13       WINDOW *form_sub(const FORM *form);
14       int scale_form(const FORM *form, int *rows, int *columns);
15

DESCRIPTION

17       Every  form  has an associated pair of curses windows.  The form window
18       displays any title and border associated with the window; the form sub‐
19       window  displays the items of the form that are currently available for
20       selection.
21
22       The first four functions get and set those windows.  It is  not  neces‐
23       sary  to set either window; by default, the driver code uses stdscr for
24       both.
25
26       In the set_ functions, window argument of NULL is treated as though  it
27       were stsdcr.  A form argument of NULL is treated as a request to change
28       the system default form window or subwindow.
29
30       The function scale_form returns the minimum size required for the  sub‐
31       window of form.
