the major difference is that the dosbox.conf variable usescancodes is set to true.
if you set it to false it might work better for you.

Maybe the windows-style of scancodes works for os2 as well
(linux has a +8 for all scancodes at some point).

Ok, I think that's it. I can imagine that there is a

1#ifdef WIN32
2..
3#else // Linux
4..
5#endif

and so OS/2 falls through to the Linux implementation.

Ok. When I come home I will try this.

PS: What's wrong with the repository? I cannot update or even login to the cvs server.

dunno.
I will file a bug report with sourceforge.
It's been out for over a week now.

hmm seems to be know issue.
anonon cvs isn't updated anymore until they have fixed things
http://sourceforge.net/docs/A04/

Ah ok. Thanks for the note.

Since anonymous CVS is dead on SF.net, could someone of the core developers append the following to line 329 in sdlmapper:

1&& !defined(OS2)

Thanks.

So OS2 has the same scancodes as windows?
That's fine then, will be added.

Thanks.

Could you please have a look at MAPPER_StartUp (at the bottom
of sdl_mapper.cpp), i assume the defines there have to be
updated as well (either the linux/windows defaults already
work for os2, or a few modifications are necessary).
Those are for the cursor keys/num block pad, thus easy to test.

Ok. Thanks I will look into it.

Ok, I had look at that code, and made it compile with the Win maps, but the whole right side of the keyboard doesn't work.
I have to make further investications for that.

Please, can somebody explain to me, how the key mapping in Dosbox works and what values I have to look at to get the mapping to work?

Have a look at static SDLKey sdlkey_map, this array has a translation
from a host-OS scancode (which sadly isn't a hardware scancode) to
SDL symkeys, so if we get scancode==1 it'll be translated into
sdlkey_map[1]==SDLK_ESCAPE.
Windows/Linux have almost the same scancode translation (linux has
an offset +8 which is removed in Bitu GetKeyCode()), and those keys
that have different scancodes require a change of sdlkey_map in
void MAPPER_StartUp(). Most likely this is enough for os2 as well.

To get a scancode for a key, search sdl_mapper.cpp for LOG_MSG("key type
and remove the comment before this line. Then hit those keys that don't
work yet, the last entry displayed by LOG_MSG is the scancode, then
you can add a custom translation in void MAPPER_StartUp().

Thanks a lot.

If it's too much trouble, just remove the usescancodes entry from
dosbox.cpp (and default the setting to false), just be sure it works
with foreign-layout keyboards (of os2).

I will do it, it's just that my new day job and driving 6h a day through Germany makes concentrating on such things difficult.

heh. I have to drive 4hrs a day so I know how it is. 😉

Hi.

I just came around to packaging everything up.
I have attached my changes in sdlmapper.cpp to this post.
Please can anybody add it to CVS?

bye Jochen
