val create_menu : ?depth:int -> layout_entry array -> bool -> t

The depth indicates the level of submenu. By default depth=0. The bool parameter indicate whether the menu should be initially shown.

val create : 
  ?hide:bool ->
  ?name:string ->
  ?background:Layout.background ->
  ?select_bg:Layout.background ->
  dst:Layout.t ->
  t ->
  Layout.t

By default, hide=false. The dst layout will contain the submenus.

returns
the layout of the main menu. This is generic menu construction function, it does not compute the positions of the entries. See example41.

val bar : 
  ?background:Layout.background ->
  ?name:string ->
  Layout.t ->
  entry list ->
  Layout.t

A menu bar, with drop-down submenus. bar dst entries creates a layout which contains the menu bar on top of the dst layout. The dst layout should be big enough to contain the submenus. Any item flowing out of dst will not get focus. The system will automatically try to shift the submenus if they are too wide, or add a scrollbar if they are too tall.
