First of all thank you very much for deep involvement. I appreciate that.

And yes, in the original message if this thread I said that I used .pos 
= .lenght and then .ensurevisibale.

So then I did nothing wrong.

Also in original message I've said "With all this differences in QT and 
GTK I can understand why" - that what I was talking about. It's not that 
I knew, it's just what I gathered from the documentation. I did not 
undertand it at first but now I do. It's, evidently, the simple fact 
that .EsureVisible does not work in GTK3. Qt is hardly a solution 
because the program should work on couple hundred of PCs where there's 
no Qt and would not be. Well, ok then. At least I'm not crazy and you 
see what I see, that already means  a lot! Thanks again.
