Hei all
We were doing a very simple prototype for a cross platform python game (same
code on s60, 770 and desktop) , and at least in the pygame(python + sdl) it
was so simple to make the bitmap solution (even with cap and simbols) take
less then a couple of hours to prototype (not clean coding etc)
Of course I cannot assure that we supported languages like hungarian, or
even our brasilian portuguese, but for the game input was ok and made in
just one day.
So I agree with jacub, if you really need, go and make a simple thing for
you the fits your need. It's not a problem at all.
I had a lot more problems with the DOOM, that needed more visual controls
then a keyboard : / but at least was playable in the end and showed
something :
maybe you don't need a full keyboard =)

Together goes the keyboard for the demo in python (you can bring it easily
to C)
Obs : this was a fast prototype of a non-python developer =) so do not look
at with demanding eyes =)

This is IMHO a very simple problem. Just a quick guess: You have to draw a
nice keyboard,
export it to BMP and load it with SDL_LoadBMP(). Then you display (blit) it
with
SDL_BlitSurface(). Don't forget to update the screen with SDL_UpdateRects().
Then you can
SDL_WaitEvent() to wait for SDL_MOUSEBUTTONDOWN events. You just need a
table
which contains the x and y coords of our virtual keyboard to decode coords
to the key
pressed. Of course you should handle shift, delete and someth
