http://www.place.org/~nop/lua-fltk-0.1.tar.gz ; read the README for
w = Fl_Window:new(300,180,"Hi there!")
box = Fl_Button:new(20,40,260,100, "hello, world!")
box:labelfont(FL_BOLD + FL_ITALIC)
function fltk_dispatch(n) if n.callback then n:callback() end end
function box:callback() fl_alert("hello, world") end
fl_cb(box) -- register box for callbacks
The two errors I've found so far are:
1) widget:label(s) doesn't stash a copy of s anywhere, so if s ever gets
garbage collected, the label will break. I believe constant strings in
functions won't be collected, so this is hidden in common use.
2) Fl_Box:new(boxtype, x,y,w,h, [label]) was the wrong constructor to pick;
it was ambiguous with Fl_Box:new(x,y,w,h, label) as far as toLua was
concerned. flconvert prefers the second.
I've been working on a more Lua-flavored API on top of the toLua fltk API;
I'll post when I get it functional.
