c++ - Is it possible to see definition of Q_SIGNALS, Q_SLOT, SLOT(), SIGNAL() macros? (Qt)

Question

Is it possible to see definition of Q_SIGNALS, Q_SLOT, SLOT(), SIGNAL() macros in Qt framework?

P.S. Google gave me nothing in this question.

Answer 1

Form qobjectdefs.h, for a non-debug compilation:

#define Q_SLOTS
#define Q_SIGNALS   protected
#define SLOT(a)     "1"#a
#define SIGNAL(a)   "2"#a

The Q_SLOTS and Q_SIGNALS declarations are only treated specially by the moc run, in the final compilation they reduce to simple method declarations. SIGNAL() and SLOT() create names from the provided signatures.
