-/** Widget description.
- *
- * A widget is an entry in a tree structure which represents a
- * rectangular area with co-ordinates relative to its parent widget.
- * This area has a distinct set of callback operations for handling
- * events which occour within its boundries. A widget may have an
- * arbitrary number of child widgets. The order within the tree
- * determines a widgets z order.
