- * WorldView.m
- *
- * WorldView is a subclass of View. It simply displays and clears a message in
- * the view. The one lesson this example shows is the modification of
- * "drawSelf::" and the call to "display". The method, "drawSelf::", should
- * not be called directly.
- *
- * Rather, "display" should be called. The display message performs
- * some necessary overhead such as bringing the View into focus by
- * constructing a clipping path around its frame rectangle and making its
- * coordinate system the current coordinate system for the application. The
- * display method then messages drawSelf::. These steps are repeated for
- * each of the View's subviews.
- *
- * Note: Any instance variables that need to be initialized before the first display
- * should be done in the "init" or "initFrame:" method. In this case,
- * drawHello is already a null value at its creation so no initialization
- * has to be performed.
