SVision

Binaries of SVPE and SVFE are available, thanks to http://www.borland.fr, where you can d/l a free TP7.
SVision is a free open source OOP GUI, I made from zero.

I am now Iam developing this project under freedos running in a dosemu session in linux.

[SV previews] [DownLoad SV]

News:

Some bugs were fixed mainly in the menus
Speeded up the output of chars (char draing procedures draw the char into a small memory buffer and then the buffer is drawed as a bitmap this is more fast then drawing pixels
2 new examples: FSF and the text viewer
Now all SV is idstrivuted as a simgle file. It is consing me too much space on my site. sorry
There is a bug when runing Windows 2000: SVGA unit stuckes the computer and you are forced to boot up. If anyone knows how to fix it let me know.

I need some help in a few things: for example how to read the mouse wheel under DOS.
I think a FreePascal or another free compiler for pascal is needed. I will also help in porting the GUI to other OS. (any volunteer?).

Bugs

On Windows 2000 (both server and profecional) all SV programs fail if they run unless the video mode is vm320x200x256 ($13). Need to work this out. On XP it just does not work, XP does not get stucked.
When you enter a menu on a movable window, the submenus do not move but they are keeped on the original place. (See this bug on the SViewer demo)

If you find new bugs please report them to dgi_il@hotmail.com .

History:
It started when I wanted to do a picture editor, and I needed a good way to load file. Instead of just writing the file using some readln, I decided to write my own open dialog.

It started from small independent windows, and then I saw I needed a menu system also. So I wrote it... I needed also to write a TApplication object for that. I needed also a good mouse server (interrupt 0x33 does not support always a good interface for showing 256 bitmaps as cursors in SVGA).

Then I wanted it to use Win95 LFN. As they are available also under DOS now I sited and wrote the code. I wrote some parts of this, and will be released as soon as I finish them. I am also planning new views to be added to the SView unit: for example a TABView to be inserted in dialog boxes, and a textviewer. The text viewer can be found in the new example I am working on: the text viewer.

It's program structure in very similar to Borland/Emprise Turbo Vision (r), the TV library in now OpenSource public domain, so there is not a chance to have any license problems. (The TV license is only for C++ Turbo Vision? I hope not...)

This version supports:

Graphics

Full support for 256 MCGA/SVGA. Including clipping .
Supports for images larger then 64K!
Palette manipulation for images as well as reissuing procedures.
Can load and save BMP, PCX, ICO and CEL files.
Basics drawing primitives (pixel, line, horizontal line, vertical line box, triangle, circle, polygon with or without filling)

Mouse

Mouse support for MCGA/SVGA.
Cursor can be also a .CUR Windows file.
Can work on interrupt or polling mode.

OOP GUI

Program and user interface very similar to Turbo-Vision. Easy to learn.
Full keyboard and mouse supported.
evKeyDown as well as evKeyUp implemented (soon probably, on next version).
Dialog boxes fully implemented. (CheckBoxes, RadioButtons, InputLine, Text lists, DropDown lists, Press buttons, Static texts etc...)
Menu-bar (keyboard and mouse).

Demo programs

SVPE: SV pictures editor

A small program for editing many pictures at the same time. You can save them in a native format, or export each picture into a well known format ( BMP, PCX, ICO, CUR). You can also import into the program pictures and save them in the same file.
The program has also a built in palette editor. It works on 6 Bit 256 palette and has some nice functions (ramp, ping pong, RGB).
This program also can edit the small ICONS in IE5 (the animating world) so you can put it in your own IE5 icon.

SVFE: Bitamp Font Editor

With this program you edit 8x8 and 8x16 bitmap fonts for using in the SV programs you make and also change the DOS font. (a small program that does it is supplied). You can save the fonts even as a PAS unit.

PicView: picture viewer

This small program is a command line utility for viewing all the supported images by SV. It supports some SVGA resolutions as well MCGA. Also can display on the screen all the VESA information available on the computer.
In the future it will be like ACDSEE. I hope.... ;-)

Pas2HTM: A converter between PAS files and HTML
This command line tool takes a normal PAS file from TP7 and writes a HTML file with syntax hightailing. It can do most of the things it should do. It need to support for user comments.

Text Viewer
This program demostrates how to build a nice file viewer. It is showed as a floating window on top of DOS, and can serve as a small demo of how to imitate text modes under graphics modes. The text mode displayed is saved into a small buffer, and the displayed is set to 640x400 graphic mode. The text screen then printed as normal string using the know procedures, and a normal window is opened on top. It will look as a graphic window and a graphic mouse are runing on text mode. This example needs a lot of work until it will be finished but in the end it will grow into a full textedito in graphic mode.

FSF - Free Spread Shit
This is shit ware for anyone who is asking, It is sopposed to be a DOS open-source project for making a spread sheet under DOS. It demostrates how to make a table view (could be inserted into the main SViews unit some day). This demo is GPL. (I dont like the virus affect of it, I like better my license, but thats life).
