<H2>DESCRIPTION</H2><PRE>
|
||
|
|
The function <B>set_menu_format</B> sets the maximum display size
|
||
|
|
of the given menu. If this size is too small to display
|
||
|
|
all menu items, the menu will be made scrollable. If this
|
||
|
|
size is larger than the menus subwindow and the subwindow
|
||
|
|
is too small to display all menu items, <B>post_menu()</B> will
|
||
|
|
fail.
|
||
|
|
|
||
|
|
The default format is 16 rows, 1 column. Calling
|
||
|
|
<B>set_menu_format</B> with a null menu pointer will change this
|
||
|
|
default. A zero row or column argument to <B>set_menu_format</B>
|
||
|
|
is interpreted as a request not to change the current
|
||
|
|
value.
|
||
|
|
|
||
|
|
The function <B>menu_format</B> returns the maximum-size con-
|
||
|
|
straints for the given menu into the storage addressed by
|
||
|
|
<B>rows</B> and <B>cols</B>.
|
