- # There are four main classes in this program. Each of
- # these classes has a definition (.h) file and an
- # implementation (.cp) file.
- #
- # The TApplication class does all of the basic event
- # handling and initialization necessary for Mac Toolbox
- # applications. It maintains a list of TDocument objects,
- # and passes events to the correct TDocument class when
- # apropriate.
- #
- # The TDocument class does all of the basic document
- # handling work. TDocuments are objects that are
- # associated with a window. Methods are provided to deal
- # with update, activate, mouse-click, key down, and other
- # events. Some additional classes which implement a
- # linked list of TDocument objects are provided.
- #
- # The TApplication and TDocument classes together define
- # a basic framework for Mac applications, without having
- # any specific knowledge about the type of data being
- # displayed by the application's documents. They are a
- # (very) crude implementation of the MacApp application
- # model, without the sophisticated view heirarchies or
- # any real error handling.
- #
- # The TShapesApp class is a subclass of TApplication. It
- # overrides several TApplication methods, including those
- # for handling menu commands and cursor adjustment, and
- # it does some necessary initialization.
- #
- # The TShapesDocument class is a subclass of TDocument. This
- # class contains most of the special purpose code for
- # shape drawing. In addition to overriding several of the
- # TDocument methods, it defines a few additional
- # methods which are used by the TShapesApp class to get
- # information on the document state.
