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 something else. The
decoded char
can now be displayed, you probably need some kind of "displaying a
text"-function (sfont.c)
for it. And so on. This all can be packed in a function like "char
*SDL_EnterText()".
An other problem would be to incoperate such a virtual SDL keyboard to the
large number of
different SDL-GUI toolkits.
For the most number of action games, you don't need to enter text during game
play. Its
enough if you do this on startup, and therefor you can use a Maemo startup
window.
This sounds good and easy to me.The bmp can even have alpha! and
perhaps the code is already there?
