|
|
The function <STRONG>set_menu_format</STRONG> 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, <STRONG>post_menu()</STRONG> will
|
|
fail.
|
|
|
|
The default format is 16 rows, 1 column. Calling
|
|
<STRONG>set_menu_format</STRONG> with a null menu pointer will change this
|
|
default. A zero row or column argument to <STRONG>set_menu_format</STRONG>
|
|
is interpreted as a request not to change the current
|
|
value.
|
|
|
|
The function <STRONG>menu_format</STRONG> returns the maximum-size con-
|
|
straints for the given menu into the storage addressed by
|
|
<STRONG>rows</STRONG> and <STRONG>cols</STRONG>.
