Hi everyone,

finally I found some time to work on the Qt application again.
(When customers needs new functionality then every thing else has to be put on hold.)

I fixed the bad behavior of my model implementation and now it works as intended.
This strange looking error, the grid I mean, and the real problem behind it gave me a lot
of headache (figurative).
Thanks to all of you, the problem could be solved.

Maybe some else can benefit from this thread.

Many thanks
Dax
