outline-item-removed

Arguments: outline child-item parent-item-if-any

This generic function is called whenever an outline-item is removed from the range of a parent outline-item or (for a top-level item) an outline widget. This can include when an item is shifted horizontally, where it is removed from one parent and added to another. The built-in default method does nothing. An application could add a method to update the domain data in a corresponding manner if needed.

parent-item-or-outline will be the parent outline-item from which child-item was removed unless it had been a top-level item, in which case it will be the outline widget itself.

child-item will be the outline-item that was removed.

See also remove-outline-item and shift-outline-item.
