是否可以看到Q_SIGNALS，Q_SLOT，SLOT（），SIGNAL（）宏的定义？ （QT）

Question

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

PS 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.

Answer 2

With visual studio - right click the identifier you're interested in and choose "Go To Definition" or press F12.
If you have Visual Assist, this can also be done with Alt+G when the VS mechanism doesn't work so well.
