To run this demo please launch DEMO.BAT in a CLIPPER 5.2 environnement.
By agreement with CA, we are supplying the sources of the original DBU program,
updated and improved for Light Lib Graphics.
┌───────────────────────────────────────────────────────────────────────┐
│Notes : Light Lib Graphics is compatible with CLIPPER 5.01a and 5.2x, │
│ but some instructions of version 5.2 of DBU (CREATE ... ALIAS, │
│ ISCHAR(), "common.ch" ...) and LLIBGTOO.PRG will make it │
│ necessary to compile with CLIPPER 5.2x. │
└───────────────────────────────────────────────────────────────────────┘
Type RMAKE DBU from the DOS command-line to build the whole set of .PRG
demonstration programs.
This command uses RTLINK as default. If you wish to use BLINKER, enter the
following command-line :
RMAKE DBU /dBLINKER
To optimise BLINKER execution speed, delete the # in line :
#Blinker incremental off.
To use EXOSPACE, begin to test a classical link with RTLINK or BLINKER
the enter EXOSPACE @DBU after you have deleted # sign in lines :
#ExoSpace PACKAGE MOUSE # Exospace mouse support
#Module GMODE From LLIBG # Must be here
#Lib EXOSPACE # Exospace library
When compilation is completed, type DBU if you want to run DBU in text mode.
Re-run DBU /G to set graphic mode.
Select a DBF file by pressing ENTER.
Press F5/View will launch a browse in graphic mode. You will no doubt
appreciate the speed of LLIB's graphic functions.
F5 Graphic allows you to evaluate the extensive possibilities offered by
Light Lib Graphics: the "Change" icon gives you GETS in graphic mode
with mouse support; with the "No" icon, you get a 3D alert box, also
supporting the mouse; the "View" icon displays values as a plot,
simple or 3D histogram, a pie-slice and much more.
F6/Samples shows you how to use the mouse with MENU TO, GETS, TBROWSE, ALERT,
..., using functions available in the two files LLIBGTOO.PRG and LLIBGTOO.CH.
If you want to go find out more about programming with LLIB, just search for
the keyword -LLIBG- in the different DBU*.PRG files. You will appreciate how
little you have to work to obtain good-looking applications. The DBU*.PRG
have not been modified much. By studying them, you will see that a very
little work is needed to complete an application with all the advantages of
graphic mode.
The files TbDemo.Prg, GetSys.Prg, gSamples.Prg, gPaint.Prg and all other gXxxx
files are examples which exhaustively demonstrate how to call the functions
of Light Lib Graphics. They use all the tools available in the files
LLIBGTOO.PRG and LLIBGTOO.CH.
LLIBGTOO.PRG give you a good idea about what you should be able to do using
Light Lib Graphics. Do not hesitate to include LLIBGTOO.CH in your applications
and to link with LLIBGTOO.OBJ. The source code is here as an exemple, feel free
to enhanced or modify it for your convenience.
Please read the NG section "USING THE LIBRARY" to get started.
We wish you the best developments with Light Lib Graphics.
