That's because of how the C++ preprocessor (the thing which you control via #define) works. The #define takes effect at the time you include the class definition (the <QString> header); when the QT_NO_CAST_FROM_ASCII is defined, the appropriate constructors which take C++ string literals are declared private. Flipping the #define after the class has been defined has no effect.

With kind regards,
Jan
