More Inheritance,o they provide further examples of the important property of inheritance and the need for virtual functions. Full details of these classes can be found in the module DIAGOBJ, although only relevant examples of the classes are given here.kidney 发表于 2025-3-27 02:35:06

Multiple Inheritance and Operator Overloading, two classes. This therefore provides an example of multiple inheritance. The buffer also provides an example of the technique of operator overloading. These classes are implemented in three general library modules, not specific to the drawing package. The first section gives an overview of the class hierarchy.Alopecia-Areata 发表于 2025-3-27 12:35:34

,Inheritance — Window Classes,with the windows on the screen and printing the diagram on a PostScript printer or a plotter understanding HPGL, the Hewlett Packard Graphics Language. Thus this chapter also describes the use of the library routines which drive the PC screen and the handling of some printers, PostScript and HPGL. TCustodian 发表于 2025-3-28 02:40:26

Multiple Inheritance and Operator Overloading, buffer for storing keystrokes. The keyboard, mouse and buffer are implemented using classes arranged in a hierarchy in which the buffer inherits from two classes. This therefore provides an example of multiple inheritance. The buffer also provides an example of the technique of operator overloading
