Hi!
Thanks for the good answers and hints.
Actually I didn't code anything with bennugd - but it seems that bennu has similar possibilities than C/SDL but is easyer to handle.
I'd like to develop some kind of text editor with (QWERT-)touchscreen-keyboard - as far as I saw there isn't a suitable solution out there (for older people - like me - with poor eyes and unskilled fingers).
Regards
