This is just the source, and searching google gives only sparse
documentation for it. And none of how to make fltk-apps display the
keyboard and receive inputs from it. Is there any "real" documentation
for it?

Well, I toyed a bit around with it and found out that the reason for the
program not launching was that in my service-file, I had written
com.cendio.thinlinc instead of com.nokia.thinlinc!!!

Anyway - program launches fine now, but still no icon in the pager! Any
advice?

And oh, thanks for your help :-)
