Ncurses - how do you get mousemask working?

[Richard Lyman]

I've tried... and I've looked around.

A few other projects have the line with 'Ncurses::mousemask...' in
them - but it's always commented out... like they couldn't get it
working either.

Is this feature not functional?

I've currently got 'Ncurses::mousemask(Ncurses::ALL_MOUSE_EVENTS,[])'
and the error 'wrong number of arguments (2 for 1)' and as soon as I
drop the second arg I get the error 'oldmask (2nd argument) must be an
empty Array' which is kinda bothersome...

Any hints? Tobias?

It's a bug in the method definition; see below.

It's a bug in the library. It's been there forever (I came across it
when I was trying to add mouse support to Raggle, then just forgot to
send a patch upstream).

Any hints? Tobias?

Err, my patch is backwards... Here's the correct one (again, attached):

Thanks for the reply, but I think I'm going to move away from
ncurses... you can't get CTRL-<Arrow> to be unique can you? I haven't
found anywhere in the docs where it allows you to detect the CTRL key
on it's own.

If you can't, then that's the straw that breaks it.

Again - thanks for the reply.

on it's own.

That's a terminal-dependent feature. If the terminal supports it,
one can write a terminfo that describes it (as a function-key).
(n)curses supports up to 60 function keys (which you would probably
find too limiting ;-)

bye.
