scim::Connection::Connection | ( | ) |
Default constructor.
scim::Connection::Connection | ( | Node * | node | ) |
Construct a connection object for node.
node | - a pointer to the Node class for this connection. |
scim::Connection::Connection | ( | const Connection & | src | ) |
Copy constructor.
scim::Connection::~Connection | ( | ) |
Destructor.
Connection& scim::Connection::operator= | ( | const Connection & | src | ) |
Assignment operator.
void scim::Connection::block | ( | ) |
Block signal transmission to a slot. The slot will not be called during any signal emissions unless it is unblocked again.
void scim::Connection::unblock | ( | ) |
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.
void scim::Connection::disconnect | ( | ) |
Disconnect a slot. The slot will not be called during any future or currently ongoing emissions of the signal it has been connected to.
