pack in tk frame for themed widgets

f = Frame(w)
configure(f, Dict(:padding => [3,3,2,2], :relief=>"groove"))
pack(f, expand=true, fill="both")

widgets

b  = Button(f, "one")
cb = Checkbutton(f, "checkbutton")
rg = Radio(f, ["one", "two", "trhee"])
sc = Slider(f, 1:10)
sl = Spinbox(f, 1:10)

packing

pack_style = ["pack", "grid", "formlayout"][3]

if pack_style == "pack"
    map(pack, widgets)
    map(u -> pack_configure(u, Dict(:anchor => "w")), widgets)

bind a callback to each widget

change_handler(path,xs...) = println(map(get_value, widgets))
map(u -> callback_add(u, change_handler), widgets)

set_visible(w, true)
