- 1. Introduction
-
- Arghh! There it is again... Your favorite application just
- wanted to inform you of some important event. And there it
- appears, the much-hated standard system requester, that
- itty-bitty window that seems glued forever to the upper left
- edge of the screen, a requester that can only be acknoledged
- using the mouse or some much too cryptic key combination (Hmm,
- I've been reading too many bad novels lately...?)
-
-
- 2. Who and why
-
- Especially Peter was very unhappy with the new style
- requesters in 2.0 (he didn't like the 1.3 version either) --
- "They have redone Workbench, it now looks slick and shiny, but
- those requesters are about as ugly as they could be", and "the
- design of the new requesters has already improved quite a bit --
- compared to Kickstart 1.3. But yet they are not yet
- state-of-the-art".
-
- Having seen one of my (mjl's) earlier tools, "CR", that
- remapped the requesters under 1.3 to something a bit more
- appealing to the eye (and IMHO, kinda much more user friendly),
- he came up with the idea of redesigning those dialog boxes.
-
- In the beginning, I was not quite happy about rewriting my
- code to suit his rather perfectionist ideas ("now leave two
- pixels here, and don't forget that line of gray to the
- right...") -- no idea how he's done it, but he finally got me to
- the point to do him the favor.
-
- So here's the result. Note that it is trimmed to fit the "new
- look" of Workbench 2.0 (hires interlace -- any other resolution
- will make it look a bit weird).
-
-
- 3. What
-
- Arq, abreviation for -- well, I forgot --, is a little utility
- to improve the look and feel of system requesters under AmigaOS
- 2.0. I won't say more... Or, as Peter put it:
-
- "If you were ever used to those really professional
- Custom-Requesters for KS 1.3 from mjl, you were missing those
- under AmigaOS-2. Well -- here they are!"
-
- Since 1.57, Arq features a sound interface -- any appearing
- requester now may be accompagnied by some user-definable sound.
- Please refer to the respective chapter for more information
- about the sound interface.
-
- Arq wedges into Intuition's AutoRequest(), EasyRequest() and
-
-
- What
-
-
- Page 3 Arq 1.83 Page 3
-
-
- DisplayBeep() vectors (as well as CloseScreen(), but you won't
- notice that one), and replaces each of those routines by our
- artist's idea of a requester, which is much more flexible and
- user friendly than the system's standard requester.
-
- Note that the graphics are stored in fax-like compression
- format. This means that you (a) won't be able to compress it
- much further, (b) having several Arq requesters open on a plain
- vanilla 68000 will slow down the system a bit.
-
-
- This archive should contain
- Arq ......... The executable
- Arq.doc ..... What you are reading now
- Arq.h ....... Include file for special features
- upd ......... The ARexx sound player daemon
- upd.doc ..... And its accompanying documentation
-
- 4. How to
-
- Just "run arq" and enjoy the improved system messages. To stop
- it, just send it a ^C via the "break" command (though I doubt
- you'll ever want to quit it).
-
- Under 2.0, you can control Arq with the Commodities Exchange
- tool. You may freely enable, disable, or kill Arq. Also,
- starting Arq a second time, will remove itself from the system.
-
- The main advantage of those requesters is (apart their look),
- that we moved the strange combination of Left-Amiga-V and
- Left-Amiga-B (of course those are working too, special favor to
- Andy Finkel) to the ESC and RETURN key, which makes life quite a
- lot easier (no more knots in your fingers).
-
- Another possibility is to use the function keys, where F1
- corresponds to the leftmost, F2 to the second, and so forth,
- gadget -- that way you can answer requesters with more than two
- buttons, like IconEdit's.
-
- Though written with 2.0 in mind, Arq does work under 1.3 as
- well -- but the layout will look a bit stretched in
- non-interlace mode. Sorry about that -- it really doesn't look
- all that bad...
-
- Please also note that this command replaces some of the
- library vectors in intuition.library -- restoring them is per
- definitionem not a safe operation. While this works most of the
- time, you may witness wonderful things happening when there is
- another tool (like srt) wedged in after Arq. So please be
- careful.
-
- A favorite seems to install AssignX in conjunction with Arq --
- please note that when using a bigger system font, Arq will find
- the so changed requester too big to be opened, and use the
-
-
- How to
-
-
- Page 4 Arq 1.83 Page 4
-
-
- original system requester instead. THIS IS NOT A BUG, but an
- intended feature.
-
-
- 5. Sounding away
-
- Instead of building the sound capability into Arq itself, we
- chose to implement it following the client-server model: a
- sound playing server, as, for example the "upd" sound daemon by
- Jonas Petersson will do all the hard work, giving you the
- additional bonus of being able to play your favorite tunes from
- your ARexx programs...
-
- The following sound IDs are used, for the corresponding
- requesters and DisplayBeep -- please refer to upd's
- documentation how these work.
-
- · warn_write_protected
- · warn_insert_volume
- · warn_delete
- · warn_printer
- · error_task_held
- · error_read_write
- · error_general
- · warn_general
- · query_general
- · beep
-
-
- 6. Programmabilities
-
- Often some application would display a requester e.g. in a
- different language, thus Arq was unable to choose the correct
- graphics to display. To circumvent this problem, Arq features
- third-party programmable animations and images since version
- 1.64.
-
- The problem was how to extend the usual EasyStruct without
- disturbing the correct working on machines without Arq installed
- or with an older version of Arq. Our (yes, it's strange)
- solution is to stick a non-breaking space (0xA0) in
- easy.es_Title.

- Programmabilities
-
-
- Page 5 Arq 1.83 Page 5
-
-
- The extended EasyStruct looks like this (and can be found in
- arq.h):
-
- struct ExtEasyStruct
- {
- struct Image *Image;
- char *Sound;
- WORD AnimID;
- UWORD Flags;
- ULONG Magic;
- ULONG Reserved[3];
- struct EasyStruct Easy;
- };
-
- To trigger the recognition of an extended structure, you have
- to put a non-breaking space in easy.Easy.es_Title, and fill
- easy.Magic with the value ARQ_MAGIC.
-
- Only then Arq will look at the extra fields to determine which
- imagery should be displayed.
-
- You have the following possibilities:
-
- One: Put the ID of the scene you want to appear into
- easy.AnimID -- Arq will display the animation of your choice.
- For example, stuff ARQ_ID_GURU in that field (see the include
- file arq.h for more ID names), and no matter what the requester
- text is, you will always get the guru graphics.
-
- Two: Put ARQ_ID_IMAGE into easy.AnimID, and a pointer to a
- struct Image into easy.Image. Arq will then display the (static)
- image you provided instead of any built-in imagery. If
- easy.Sound is non-NULL, Arq will also attempt to play the sound
- with the given name (please refer to the chapter about "upd" and
- sounds for more details).
-
- After having filled out the ExtEasyStruct structure, submit it
- to the EasyRequest() routine, like this:
-
- EasyRequest(&MyExtEasyStruct->Easy)
-
-
- 7. Recent changes
-
- In version 1.61, people complained that, if Arq opened its
- requester while some screen obscures the active screen, they
- would not notice the requester. So this was changed to the first
- screen in 1.66. Now people are actually complaining it opening
- on the first screen. I've changed it back to the active screen.
- Oh well.
-
- The buttons have a visual feedback for keyboard operation
- since 1.66.

-
-
- For 1.83, I incorporated much of the enhancements suggested
- that I could fit in my rather tight spare time. I'm afraid, some
- of the things I wanted to add are still outstanding, but I felt
- a new release tackling known problem areas were more important
- right now. Rest assured I have not forgotten your enhancement
- request...

-
- We are not really happy yet with the graphics for "?" and

-
- Also, don't hesitate to yell when you've got graphics you'd
- like to see in the next version. As of version 1.66 I've heard
- very little "direct" response -- I was able to catch a few
- comments in some newsgroups, but that's it basically. Remember,
- if you don't tell me (me, and not some unrelated, innocent

- problems or ideas you have, chances are good you won't find them
- realised in future versions.
