(* First, open this modules for convenience *)
open Tk
(* initialization of Tk --- the result is a toplevel widget *)
let top = openTk ()
(* create a button on top *)
(* Button.create : use of create function defined in button.ml *)
(* But you shouldn't open Button module for other widget class modules use *)
let b = Button.create ~text: "Hello, LablTk!" top
(* Lack of toplevel expressions in lsl, you must use dummy let exp. *)
let _ = pack [coe b]
(* Last, you must call mainLoop *)
(* You can write just let _ = mainLoop () *)
(* But Printexc.print will help you *)
let _ = Printexc.print mainLoop ()
