~ScopedConnection() noexcept
disconnects the connection
bool isConnected() const
check if the connection is connected to the signal
represents a connection to a signal
ScopedConnection & operator=(const Connection &connection)
assigns a connection
void disconnect()
disconnects from the signal
void release()
releases the connection so that it won&#39;t be disconnected when this ScopedConnection is destructed ...
disconnects a Connection automatically upon destruction
bool isConnected() const
check if connected to the signal
void disconnect()
disconnects the connection manually
