Function documentation

Magnum::Ui::EventConnection::~EventConnection()

Destructor.

If data() is not DataHandle::Null and is valid, removes the connection from associated layer().

EventLayer& Magnum::Ui::EventConnection::layer()

Event layer containing the connection.

If data() is DataHandle::Null, the reference may be dangling.

const EventLayer& Magnum::Ui::EventConnection::layer() const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

DataHandle Magnum::Ui::EventConnection::data() const

Connection data handle.

If DataHandle::Null, the instance is moved out or released.

DataHandle Magnum::Ui::EventConnection::release()

Release the connection.

Returns data() and sets it to DataHandle::Null so it's no longer removed at destruction. Removing the connection using EventLayer::remove() before the layer itself is destructed is user responsibility.
