<H2>DESCRIPTION</H2><PRE>

2000-07-09 10:46:08 +08:00
|
|
|
Every form has an associated pair of <B>curses</B> windows. The
|
1997-05-15 12:00:00 +08:00
|
|
|
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
|
2000-07-09 10:46:08 +08:00
|
|
|
code uses <B>stdscr</B> for both.
|
1997-05-15 12:00:00 +08:00
|
|
|
|
2000-07-09 10:46:08 +08:00
|
|
|
In the <B>set_</B> functions, window argument of <B>NULL</B> is treated
|
|
|
|
|
as though it were <B>stsdcr</B>. A form argument of <B>NULL</B> is
|
1997-05-15 12:00:00 +08:00
|
|
|
treated as a request to change the system default form
|
|
|
|
|
window or subwindow.
|
|
|
|
|
|
2000-07-09 10:46:08 +08:00
|
|
|
The function <B>scale_form</B> returns the minimum size required
|
|
|
|
|
for the subwindow of <I>form</I>.
