+ * This class is the graphical version of a UMLUseCase. A UseCaseWidget is created
+ * by a @ref UMLView. An UseCaseWidget belongs to only one @ref UMLView instance.
+ * When the @ref UMLView instance that this class belongs to, it will be automatically deleted.
+ *
+ * If the @ref UseCase class that this UseCaseWidget is displaying is deleted, the @ref UMLView will
+ * make sure that this instance is also deleted.
+ *
+ * The UseCaseWidget class inherits from the @ref UMLWidget class which adds most of the functionality
+ * to this class.
