Eiffel_vision 1.0 demo

Written by Andreas Haeferer at Technical University of Ilmenau (Germany)

• Demo for Eiffel/S 1.3 under DOS
• 26 March 1995.
• (Not to be confused with ISE's EiffelVision cross-platform graphics library)

eiff_vis.exe (156,538 bytes)

Introduction

This is a demo version of an Eiffel_Vision based application. This archive contains a compiled EXE-File and a few eiffel classes (*.e) to show how simple it is. The source to the library is not included, but the short forms are in the *.fea files. At this time the features are in English but the comments are in German (cause I'm a German student).

With this demo I want to see if there are people out there who want to code in MS-DOS Eiffel, not just for theoretical purposes but also to produce programs with a professional look-and-feel like Borland's Turbo-Vision.

At this time the system will distributed as Freeware. If you are interested in this Cluster please send a mail to haeferer@prakinf.tu-ilmenau.de

Features

• DOS-Mode
• Mouse Support
• Multi-Window-Desktop with overlapped windows

Usage

Simple features are available to access windows, for instance:

• setdeskchar
• setdeskstring

Buttons are simple to use:

• create the button
• set a command-code for the button
• insert the button in the window

If the button is clicked (by mouse or RETURN-key) the command-code will be sent to the Window (to be used by overriding the check_command feature of the window

Look at the *.e Files within this demo to see how simple it is.
