Arguments: outline index
This generic function is called whenever the mouse cursor moves over
an outline-item of an
outline widget. An
application could add methods to be notified whenever this happens,
such as to show a help message about the value of
the outline-item.
outline-item-mouse-out will be
called when the mouse cursor moves off of the item. The default
method does nothing.
outline is the outline widget that
contains the outline-item
that the mouse has moved over.
index is the index of
the outline-item that the
mouse cursor has moved over. This is the zero-based index within the
set of items that are currently shown, and therefore depends on which
items are open at the moment. The outline-item object is not passed for efficiency
reasons, because it takes a bit of time to look it up and in most
cases it will not be used. If you do want to find
the outline-item itself
(typically to call value on it
to retrieve its value), then pass this index to
outline-item-from-index.
