Interface QMetaObject.Connection

All Superinterfaces:
Cloneable
Enclosing class:
QMetaObject
public static interface QMetaObject.Connection extends Cloneable
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(Connection). 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.
