Subject: | labltk bind ~events list questions/bugs? |
Hi, a few labltk questions: 1. Does the ~events list passed to Tk.bind mean the callback should get all of those events? I can't think of what else it's for, but it doesn't seem to work correctly. I only get one of the types, or sometimes none. This is on Win98 with tcl/tk 8.3. Here's some example code: open Tk let _ = let top = openTk () in Wm.title_set top "Simple OCaml Tk App"; Toplevel.configure top ~height:200 ~width:200; print_string "\n"; bind top ~events:[`KeyPress;`ButtonPress] ~fields:[`KeySymString;`Type;`Detail] ~action:(fun ev -> Printf.printf "%s %d %s\n" ev.ev_KeySymString ev.ev_Type ev.ev_Detail ); Printexc.print mainLoop () If I bind the list separately it seems to work, but I haven't tested it thoroughly. 2. As another question, if I have ~events:[`Modified ([`Shift],`KeyPress)], sometimes I just get the keys that were pressed when the shift key was down, sometimes I get a zillion Shift_L events, and sometimes I get nothing. 3. I'd like to be able to distribute an executable compiled with labltk and lablgl without having people have to have tcl/tk installed. Has anybody successfully statically linked tk into an ocaml app? Perl/Tk is set up such that it doesn't depend on the tcl/tk distribution, so I assume this is possible. Would it be a ton of work? Chris
