In case you ever do some Qt programming, and work with QObjects (needed for Qt’s signals and slots), you might run over a strange compiler error, something like “bla bla bla vftable bla bla” (sorry, but I don’t have the exact error message in my head…if I reproduce the error sometime, I’ll update my post).
The clue is, instead of searching for errors in your code, just delete all the MOC and other generated files, clean the solution and rebuild it.
The error should be gone…
Other than that, I really like Qt and Qt Creator. It simplifies life big time! At least as far as it can get with C++ (silent hoooorraayyy for C# ).
