Does Qt offer a (guaranteed) debug definition?

Question

Does anyone know an officially supported way to include debug-build only code in Qt? For example:

#ifdef QT_DEBUG
// do something
#endif

Answer 1

Qt defines QT_NO_DEBUG for release builds. Otherwise QT_DEBUG is defined.

Of course you are free to specify any DEFINES in your .pro files and scope them for either debug or release.
