pub fn set_menu_format(
    menu: Option<MENU>, 
    menu_size: MenuSize
) -> Result<(), NCurseswMenuError>

Expand description

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 sub-window and the sub-window is too small to display all menu items, post_menu() will fail.

The default format is 16 rows, 1 column. Calling set_menu_format() with a menu of None will change this default. A zero row or column argument to set_menu_format() is interpreted as a request not to change the current value.

If menu is None then the default value is set.
