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.
Move-constructs a Connection instance, making it point to the same object that o was pointing to.
Create a copy of the handle to the other connection
Creates a Connection instance.
Move-assigns other to this object, and returns a reference.
Assigns other to this connection and returns a reference to this connection.
Destructor for QMetaObject::Connection.
[since 5.15]void Connection::swap(Connection &other)
Swaps this Connection instance with other. This operation is very fast and never fails.
This function was introduced in Qt 5.15.
true if the connection is valid.
The connection is valid if the call to QObject::connect succeeded. The connection is invalid if QObject::connect was not able to find the signal or the slot, or if the arguments do not match.
