; Note that MENU can define both menues and submenues.
; If you want to use any C operators (such as "|", "&", etc.), do it WITHOUT
; any spaces between the arguments (the parser is simple and weak).

MENU subMenu1 15,0 VERTICAL
; This is a vertical menu, placed at (15,0).
{
; There are three items, all of them will call functions.
; The first and third ones are normal functions, see GEOSLib documentation for
; information about what the second function should return (it's a dynamic one).
    "subitem1" MENU_ACTION smenu1
    "subitem2" MENU_ACTION|DYN_SUB_MENU smenu2
    "subitem3" MENU_ACTION smenu3
}

;; Format:  MENU "name" left,top ALIGN { "itemname" TYPE pointer ... }

MENU mainMenu 0,0 HORIZONTAL
; Here, we have our main menu, placed at (0,0), and it is a horizontal menu.
; Because it is a top-level menu, you would register it in your C source by
; using:  DoMenu(&mainMenu);
{
; There are two items -- a submenu and an action.
; This calls a submenu named subMenu1 (see previous definition).
    "first sub-menu" SUB_MENU subMenu1
; This will work the same as an EnterDeskTop() call in C source code.
    "quit" MENU_ACTION EnterDeskTop
}

;; Format:  HEADER <GEOS_TYPE> "dosname" "classname" "version"

HEADER APPLICATION "MyFirstApp" "Class Name" "V1.0"
; This is a header for an APPLICATION which will be seen in the directory as a
; file named MyFirstApp with the Class-string "Class Name V1.0"
