-
- Hello! This is the introduction to the all-new "req.library"!
-
- What is it?
-
- Req.library adds user-friendliness to the Amiga's user interface.
- While Intuition does supply requesters, they have certain limitations and
- are awkward to set up. We designed ours to be quick and easy to set up, as
- well as adding features. The text requester has PRINTF style formatting
- built in! There is a colour requester, a very powerful file requester, a
- string requester (allowing the user to enter a line of text), and an
- integer requester (allowing the user to enter an integer number). There
- are also low-level support routines, such as routines to create any of the
- Amiga's gadgets, as well as a real-time scroll routine.
-
- The nice thing about the gadget creation routines, is that they allow
- you to create gadgets from parameters, meaning that you can allocate memory
- and have your gadgets constructed there. This allows you to use gadgets in
- code that is meant to be re-entrant. This normally wouldn't be possible
- with gadgets. The size necessary for each gadget has been defined, and you
- will find the definitions in reqbase.i and reqbase.h.
-
- (Please see req.doc for a more comprehensive explanation).
-
- Here is an overview of the files included in this ZOO archive:
-
- areqglue.o Gluecode for Aztec C. Link in with your programs.
- lreqglue.o Gluecode for Lattice C. Link in with your programs.
- reqglue.asm Sourcecode for the gluecode.
- customizefile.asm How to customize the file requester.
- customizefile The executable of the file requester customizer.
- reqbase.h The C include file. Put it in include/libraries
- reqbase.i The asm include file. Put it in include/libraries
- showoffreq.c The C source code for the req demo program.
- showoffreq The req demo executable.
- req.library The actual library. This goes in libs:
- reqproto.h The prototype file for Lattice C
- req.doc The instructions and calling conventions.
- read.me This file
- macros.i Some handy macros.
-
- -----------------------------------------------------------------------------
- Included is a demo program called Showoffreq, which opens a screen with
- text gadgets in it, one per requester. If you wish to experiment with the
- requesters, this might be a good place to start.
-
-
- To compile showoffreq.c under Lattice, use:
-
- lc -Lcd+lib:lreqglue.o showoffreq
-
-
-
-
- To compile showoffreq.c under Aztec, use:
-
- cc -o o/showoffreq.o showoffreq.c
-
- ln -w +Q -o showoffreq o/showoffreq.o lib:areqglue.o -lc
-
- -----------------------------------------------------------------------------
-
- For Assembly
-
- -----------------------------------------------------------------------------
-
- To use req.library from assembly language is quite easy. So far,
- nothing's been said about it, so here is some info.
-
- First of all, the library is EXACTLY like system libraries; you open
- it, call functions, and then close it. We've included some macros that may
- make working with it a bit easier. All you have to include to actually use
- the req.library is reqbase.i. This contains all the function offsets. You
- may wish to call the functions directly, or use a bit of gluecode to make
- things even easier. If you wish to do it all yourself, then all you've got
- to do is include reqbase.i. If you wish to use some pre-made function
- setup, then you have to link with the appropriate reqglue.o (lreqglue.o for
- Lattice, and areqglue.o for Aztec).

-
- To link with lreqglue.o (for Lattice), an example linkfile might look like
- this:
-
- ---cut here---cut here---cut here---cut here---cut here---cut here---cut here
-
- FROM
- lib:startup.o
- obj/file1.o
- obj/file2.o
- obj/data.o
- obj/menus.o
-
- LIB
- lib:amiga.lib (or lib:lvo.lib if you have it)
- lib:lreqglue.o
-
- TO
- file
-
- nodebug smallcode smalldata
-
- BATCH
-
- ---cut here---cut here---cut here---cut here---cut here---cut here---cut here
-
- and to use this linkfile, just say:
-
- blink with <linkfile>
-
-
-
-
- \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
-
- To link with areqglue.o (for Aztec), and example linkfile might look like this:
-
-
-
- ---cut here---cut here---cut here---cut here---cut here---cut here---cut here
-
- ln -w +Q -o file1 o/file1.o lib:areqglue.o -lc
-
- ---cut here---cut here---cut here---cut here---cut here---cut here---cut here
-
- and to use this linkfile, just say:
-
- ln -f <linkfile>
