The Fvision Class Bank is a work in my university. I have a strong interest in object-oriented thinking to object-oriented programming and Turbo Vision worship with Borland Pascal, the TURBO Vision Worship, and Turbo Vision. Is based on DOS-based text interface, so I decided to develop a graphical interface-based application framework, eventually completed the prototype of fvision for two years, but the DOS is no longer popular, so this class library has not continued to develop Go down. However, I personally think that this class is still more comprehensive, including event drivers, window management, memory management, support, Chinese input, editor, database, image processing, sound support, memory, memory, Serial communication and other aspects, and the structure of the class library is also relatively reasonable, and the superiority of object-oriented object is taken. The main application of FVISION is based on this class library to develop many tools, including Z80 assembly and simulation development environments, DBF database systems, image processing systems, RPG game development tools, etc., we used to use our own game development tools (named GT Develop a prototype of a RPG game.
