(* 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 ()
