49        controls (e.g. toolbox controls).
50
51    <p>
52    Each state change is to be broadcasted to all registered
53	status listeners. The first notification should be performed
54    synchronously from <member>XDispatch::addStatusListener()</member>;
55        if not, controls may flicker. State listener must be aware of this
56    synchronous notification.
57    </p>
58
59    <p>
60    The state consists of enabled/disabled and a short descriptive text
61	of the function (e.g. "undo insert character"). It is to be broadcasted
62        whenever this state changes or the control should re-get the value
63	for the URL it is connected to. Additionally, a context-switch-event
64	is to be broadcasted whenever the object may be out of scope,
65    to force the state listener to requery the <type>XDispatch</type>.
