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.
