Connection Classclass QMetaObject::Connection
|Connection(const Connection &other)|
|Connection &||operator=(Connection &&other)|
|Connection &||operator=(const Connection &other)|
|bool||operator bool() const|
Represents a handle to a signal-slot (or signal-functor) connection.
It can be used to check if the connection is valid and to disconnect it using QObject::disconnect(). For a signal-functor connection without a context object, it is the only way to selectively disconnect that connection.
As Connection is just a handle, the underlying signal-slot connection is unaffected when Connection is destroyed or reassigned.
