    \brief The QDBusContext class allows slots to determine the D-Bus context of the calls.

    When a slot is called in an object due to a signal delivery or due
    to a remote method call, it is sometimes necessary to know the
    context in which that happened. In particular, if the slot
    determines that it wants to send the reply at a later opportunity
    or if it wants to reply with an error, the context is needed.

    The QDBusContext class is an alternative to accessing the context
    that doesn't involve modifying the code generated by the \l
