Member Function Documentation

Connection& scim::Connection::operator= ( const Connection src)

Assignment operator.

Block signal transmission to a slot. The slot will not be called during any signal emissions unless it is unblocked again.

Unblock a previously blocked slot. A blocked slot is skipped during signal emissions and will not be invoked, unblocking it (for exactly the number of times it has been blocked before) reverts its "blocked" state, so the slot will be recognized by the signal system and is called upon future or currently ongoing signal emissions.

Disconnect a slot. The slot will not be called during any future or currently ongoing emissions of the signal it has been connected to.
