Connection Class

Class Connection is declared in struct QMetaObject.

Public Functions

Connection(const Connection &other)
Connection()
Connection &operator=(const Connection &other)
~Connection()

Detailed Description

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.
