syntax error : identifier 'QSqlRelationalDelegate'

I did.
What's killing me is that the examples have compiled when I compiled QT. I used vs2005 from the command line.
the funny tthing also is that if I take the complete sql example relationaltable.cpp and paste it into my files, it also fails with the same error.

Try rewriting the messing code line manually - sometimes you might be pasting some weird whitespaces from an external source and the compiler will complain.

I just had the same problem. Solution is:
Go to Project -> Properties -> Configuration Properties -> C/C++ -> Preprocessor
Add QT_GUI_LIB to Preprocessor Definitions.
