Описание (Description)
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.
