Subject: Think Pascal Scrolling DITL's
From: [e-mail]

Organization: BHP Steel Group

For some time I have been coming to grips with Think Pascal's (V 4.0, system
6.0.7 on a MacPlus) dialog classes.   (I like the joke in the user manual about
having an 'aha' experience after a couple of weeks).

I am now trying to implement a scrolling DITL (The ones where you click on a
word and it appears in a text edit box underneath).  I originally had a static
text DITL.  When I ran my program this appeared without any worries.  I changed
the static text to @$CScrollPane$ScPn$1030 as I believe is necessary.  I copied
the ScPn resource across from the 'New Class Demo' program that came with Think
Pascal, and made sure that the resource id was correct.  However, when I run my
program, I get a vertical scroll bar, and that's all.  The DITL is not outlined
as they usually are.    Can anyone suggest what it is that I am not doing
correctly?

Also, a couple more questions: How do I tell the TCL which values to display in
the scrolling pane?  And how do I link a text edit item to a scrolling pane?
That is, if I have two text edit boxes, how does the TCL know which text edit
item to display the values in?

Thank you for your assistance.

Subject: Questing about Think C debugger and After Dark Modules
Date: 12 May 92 19:17:34 GMT


Okay, I'm new to Mac programming (but not C programming or programming in
general) so please forgive my naivete about the Mac environment.

I figured a nice little project to start with - to help boost my morale and get
me really going - would be to write a nice little After Dark module and play
with for a while before working myself up to a couple other projects I have in
mind.  The problem I'm having is that I can't figure out how, once I've gotten
the thing together, I would debug it with the Think C debugger.  Since the AD
module is Code Resource that get's "loaded" into AD when it is to be run, then
doesn't that mean that I have to somehow get the Think C debugger to run
"around" the whole AD application as well as my code resource?  Or do I have
this all wrong and there is really a very simple way of doing this?

Perhaps a more general way of putting this is this:  Is there any way to debug
a code resource that is not a standalone resource (ie. it makes calls into some
other piece of code that loads it) where the loader is NOT part of the Think C
Project?

Or is the answer that I am out of luck and I need to use something like
MacBugs?  Also, as a side note, would I be any better off if I was trying to do
this via MPW (SADE?) instead of using Think C?

Thanks,

I have the same question, but with hypercard XCMDs.  My guess is that the
answer is to create a dummy app in think C that will set up the required
environment.  However, this seems like a lot of trouble to me...

Unless After Dark provides a debugging testbench application for
Think C that mimics the environment your AD module will run in, the
answer is you'll have to use Macsbug, TMON Pro, or Jasik's The Debugger
to do your debugging.

It isn't that difficult if you have the source code *and* if your XCMD/XFCN
doesn't use any of the Hypercard callback routines. Basically, you can set
up a dummy paramBlock structure pretty easily and call your XCMD/XFCN through
it. I was able to add the code of an XCMD to a TCL project very easily using
this method. It was a quick-and-dirty approach to adding a bunch of existing
XCMD code to an application without having to recode a front end and new
entry calls to the XCMD code. If there is any interest I can post the code,
although like I said, it is just a quick-and-dirty hack.

    I don't believe that I am permitted (under NDA) to comment on the
details of the Translation Manager, but I think it would be permissable
to say thbat XTND is a level beneath the Translation Manager which is a
higher level "kind o' thing".

    Think of the difference as the Translation Manager is similar to
the Communications toolbox, and XTND is like the Apple Modem Tool.

According to Apple at the WWDC:

The Translation Manager is the top, system-software layer, which will take
care of automatically hooking translation to double-clicking icons (like
Hand-Off), the Open File dialog, Subscribed Stuff, and the Clipboard.  This
is really nifty functionality, and will not require any work by the
programs.

The next layer down is the Translation System layer, where the DataViz and
MasterSoft engines work (and XTND if it continues, which is uncertain).
The Translation Manager will arbitrate and work with all Translation
Systems.

Lower still are the Translator modules, which talk to the various
translation systems.

There will be APIs of some sort for the Save File dialog, but it will not be
automatic like the Open File dialog.

(I forgot drag-and-drop, where the TM will improve the highlighting for apps
that can translate documents).

Technically, the top level looks really nice, and the demo was good.

I continue to worry about the problems of distributing Translation Systems
and Translator modules.  Will everyone have to buy the systems from the
third parties (who Apple has said they will support)?  Will developers have
to license translators or Translation Systems?  How many times will users
end up paying for this?

Sigh.

Subject: Memory Mapping of Video
Date: 17 May 92 17:18:00 GMT
Organization: U Texas Dept of Computer Sciences, Austin TX

I noticed something strange the other day while playing around with video
memory.

I have an SE/30 with a RasterOps 264/30 (a 24-bit color card) hooked up to a
Seiko 1445 14" monitor.

I was storing values directly into video memory starting at 'ScrnBase.'  I
had the card set at 8-bit depth (256 colors) and noticed that at each address
starting at ScrnBase, I could store a byte directly to my display.  This
worked as it should for the first 640 bytes--but at the 641st, the byte values
were no longer storing to the screen (and wrapping to the next line as I
suspected they would.)  In fact, I had to store 384 extra bytes before the
line would wrap to the second line on the monitor.  At 'ScrnBase'+#1024, the
second line began.  I verified that this occurred for all lines on the screen
and it seems that a full screen line is 1024 bytes, with only the leftmost
640 bytes actually displayed on the monitor, followed by 384 bytes which were
writable and readable but displayed nowhere.  384 bytes doesn't seem to
correspond to anything I can think of.

Does anyone know why this occurs and could someone explain to me the cause of
this?  It would seem that all screen memory would be contiguous.  I thought
that perhaps it was related to the fact that my color card is a 24-bit card,
but that doesn't explain 384, which is certainly not 640*2 which you would
expect if writing off into memory reserved for 24-bit modes.

Oddly, my friend experiences the same behavior on his MacII with an Apple
8-bit color card (the very first version.)  His screen lines wrap at 1024 byte
intervals in 8-bit monitors settings.

The active display area seems to be left-justified on 1024 byte rows.

What is that 'hyperspace' to the right of the active screen area?  Do all Mac's
behave this way at 8-bit depth?  What does the 384 byte leftover stem from?
If anyone can straighten this out for me, I'll be able to sleep again.  This
is something I just can't seem to find information on in any of the reference
manuals I have (IM 1-6, TechNotes 4.0.4, ThinkRef, et.)

Even pointers to information which describe this would be helpful.

Thanks!

BAD BAD BAD !

Look in the UseNet Mac Programmers Guide for advice on this;
it's covered in good detail. (along with handling different
screen depths, SwapMMUMode and other stuff needed)

   This worked as it should for the first 640 bytes--but at the 641st, the
   byte values were no longer storing to the screen (and wrapping to the next
   line as I suspected they would.)  In fact, I had to store 384 extra bytes

That's because it's easier to add a k per line. Inside Mac V goes into
GREAT detail about how color quickdraw works, and describes the pixMap
structure, which also tells you how many bytes are in a row (not necessarily
the same as the number of pixels in a row) - check it out ! IM VI goes on to
explain 24bit video and other things.

   What is that 'hyperspace' to the right of the active screen area?  Do all
   Mac's behave this way at 8-bit depth?  What does the 384 byte leftover

   of the reference manuals I have (IM 1-6, TechNotes 4.0.4, ThinkRef, et.)

GO back to reading, do not pass GO, do not collect $200.

I promise, this is covered in very good detail in inside mac V and VI.

Subject: list manager alternative
Date: 18 May 92 14:32:12 GMT
Organization: ooc.uva.nl

I've reached the point where the list manager no longer meets my
demands (and, as the tech notes point out, this point should be
reached pretty soon for anybody with serious 'list'like demands.

Specifically, I need to resize individual cells - the list manager
limits cells to one uniform size.

As a result, I'm about to re-write the listmanager for my own
purpose (hopefully winning some performance because the list manager
'knows' about my data structures - I expect to loose performance
because I want more features out of it - if I'm lucky, this evens out)

Now the question: has anybody already done this? If so, are you proud
enough of it to show me your code? Any caveats you want to share?

I haven't done it so I can't share code, but I do have a caveat,
nontheless.

I suggest you give the calling code some access to any scroll bars (or
other controls, for that matter) that your list code creates.

A couple of years back, I wrote code to let you create panes within
windows and to be able to treat all of these panes as if they had there
own coordinate system.  If you do this, you can never call
"DrawControls", because all the controls in different panes are in
different coordinate systems and most of them will show up in the wrong
place.  Instead each pane keeps a list of it's controls and call
Draw1Control, after setting up the coordinate system.  [I recently
started playing with TCL and discovered it has a system for doing this
nearly identical to my own - I guess that's a good sign...].

One problem with this is that the list manager draws that darn scroll
bar whenever it wants (and when it wants isn't always at a sensible
time, especialy under system 6).  Combine that with the above "pane"
scenario and you get a random looking scroll bar popping up somewhre in
the window.  If you provide the user of your code with some way to
enable/disable drawing that scroll bar, you can avoid this problem.

Has anyone had this problem with TCL?  From my glancing at the code it
looks like they have not defended against it either (the old "he who
uses the list manager gets what he deserves" stratagy - can't say that
I disagree).

Hi!

We're thinking about expanding one of our Hypercard-based courseware
projects into an application, probably MacApp or THINK C based. This is
still a while off, but I need to figure out how much money to budget for.

I realize that there may be a more appropriate group to post this in, but
I'm not sure which one it is. The biz one looked pretty sparse, so I
thought I'd throw this out here.  I have no idea what to budget for, as
I've run into folks charging from $40 to $100 an hour.

The project will be fixed-term (1 year) working full-time, either in our
lab at Stanford or at a separate site (or both). Development will
Object-Oriented, and will involve Quicktime, System 7 support, some
cross-platform work (e.g. importing images), and database knowledge.
Strong User Interface knowledge is a plus, although I'll be doing most of
the interface design.

Obviously, benefits will need to be considered as well.

Can anyone give me some feedback on this, or tell me where I can get more
information?

Thanks!

Try the "Macintosh Services Directory" from the MZ Group.  I think APDA
sells it, or you could try an Apple dealer, or call 800-927-1100x400
and order it direct.  It contains listings of hundreds of consultants,

Another wierd case <sigh>.  In using MacTCP, I make the call
PBControl(&pb, TRUE).  pb.ioCompletion = &iocomplete.  iocomplete is a
function defined in strict type accordance with the template that
comes with MacTCP.  The problem is that while the PBControl call
returns, it never seems to call iocomplete.  Ideas?  Thanks in advance...

What is that "&" doing there? That's possibility 1.

What is this returning to you? Are you sure that it is returning noErr?
If the ioCRefNum in the pb is wrong, it's gonna complain. That's
possibility 2.

And what sort of call are you making? A call to TCPPassiveOpen with a
0 (i.e. infinite) timeout will not complete until someone makes a
connection. That's possibility 3.

Anyone else?

I'm calling TCPCreate, but asynchronously.  Thus, according to IM vol II,
a return of noErr (which I get), just means that the call was successfully
placed on the queue.  I'm pretty sure that the ioCRefNum is right (I know that
the call to OpenDriver completes with noErr and that it sets the value of
a variable to a # between -1 and -32;  is there a way aside from that to know
that it's "right"?).  Since last posting I have discovered that a constant polling
of ioResult yields a "busy" that never seems to end...  it goes on for as long
as I care to leave it (which is obviously too long :).

If any other ideas spring forth, please e-mail to save bandwidth.  I don't need
program problems _and_ flames all at once...

Subject: How to update the whole screen???
Date: 13 May 92 09:07:59 GMT

Hi all,


   I am just a beginner at programming the Macintosh so if this is a really
easy problem, don't flame me!   My problem is that I have created a color
grafPort of the same dimension as the screen, did some drawing to it, and then
disposed it.  Yet, nothing gets updated.  So, I add:

   InvalRect(thePort^.portRect);

but then the program crashed.  I know there is got to be some way to update
everything on the screen.  Hope you Mac gurues out there can help me out.

Thank you very much in advance!

Well, your program crashed because _InvalRect (and _InvalRgn) only work on
windows.  They manipulate the updateRgn, which plain grafPorts don't
have.

Here's some code to use to cause the screen(s) to be completely redrawn:

FUNCTION OpenGlobalPort (storage: Ptr; inColor: boolean): GrafPtr;
BEGIN
 IF inColor THEN
  OpenCPort(CGrafPtr(storage))
 ELSE
  OpenPort(GrafPtr(storage));
 CopyRgn(GetGrayRgn, GrafPtr(storage)^.visRgn);
 GrafPtr(storage)^.portRect := GrafPtr(storage)^.visRgn^^.rgnBBox;
 OpenGlobalPort := GrafPtr(storage);
END; { FUNCTION OpenGlobalPort }

 PROCEDURE RepaintScreens;
  VAR
   oldPort, bigPort: GrafPtr;
   bigPortRec: GrafPort;
 BEGIN
{part 1}
  GetPort(oldPort);
  bigPort := OpenGlobalPort(@bigPortRec, false);
  PaintRgn(bigPort^.clipRgn);
  SetPort(oldPort);
  ClosePort(bigPort);
{part 2}
  DrawMenuBar;
{part 3}
  PaintBehind(WindowPeek(FrontWindow), GetGrayRgn);
 END; { PROCEDURE RepaintScreens }


Comments:

Part 1 is there to take care of those wierd cases where the area past the
rounded corners of the screen has been "contaminated".  I couldn't think of
a better universal way to draw past the edge of the grayRgn.
Part 2 takes care of the menu bar.
Part 3 is the magic that takes care of all windows, plus the Finder's
desktop.  See the Window Manager chapter of IM-I for more about how/why this
works.

I do this kind of messing about frequently myself. To save putting a call
into all my test programs do the screen refreshing, I wrote an FKEY to solve
the problem once and for all. I'm enclosing it in this message; paste it into
your System file with ResEdit, and then you can just press command-shift-9 (or
you can give it another number, if you prefer) to refresh the screen at any
time.

(This file must be converted with BinHex 4.0)

So who says .hqx files can't be a valid contribution to a discussion?

Did you just create a GrafPort, or did you create a window?  You can actually
have GrafPorts and draw into them without a window.  If you dispose of a
GrafPort, there's no reason for the WindowManager to invalidate any of the
WindowManagerPort.

By the way, I once did a little test routine that would set the port to the
WindowManagerPort (a no-no right there) invert the invalid region twice (to
leave it normal) and set the port back.  This was handy for figuring out what
the invalid region actually was (And to find out that I was calling
BeginUpdate for the wrong windowPtr....).  It was educational.  Call it right
after BeginUpdate.

Howdy, y'all.  I've got a quick question that I can't seem to
resolve.  How does one put color icons into menus?  I've seen
this done (heck, even the Finder does it), and I know how to
put black and white icons in, but color escapes me.  (I know it's
going to be something really simple that I missed, but hopefully
this will save me a few hours of work...)

For reference, I'm working in MacApp 3.0.

Thanks.

Anywhere you use an ICON resource, if there is a cicn resource of the same
ID, then it will be used instead.  Pretty tough, huh?

ok, well, how about color icons in the menubar, ala the apple icon?
will this require writing an MDEF, and if so, can someone point me
in the right direction for that? (I have IM I-V, but not VI)
Is it possible to, say, change a character in the Chicago font to
simulate this?  These are probably silly questions, but I'm inter-
ested, so don't be too harsh.

    Actually this would require either writing an MBDF (MenuBar Defination)
or patching a trap (like _DrawString).

If you have a CD-ROM, you can join APDA and get a subscription to
develop for ~$25 (4 quarterly issues). This not only includes Inside
Mac's 1-6 (electronicly) but also the Tech. Notes and other stuff
(again, all on the CD).

The subject says it all.

How can I tell if the printer I am writing to supports Postscript?

First off, why do you want to know if a printer supports postscript?
According to IM, you should NEVER assume anything about printing, NOR
should you try to do anything fancy...The problem is that you really
cannot tell if the printer you are going to is postscript, unless you have
a complete list of all of Apple's wDevs that they have issued and what
printers were issued to what wDevs and whether or not they support
Postscript.  Let me tell you, the number cannot be too small because I
got two wDevs for printer drivers I wrote last summer and they were in the
130-140 range.  Now either Apple blocked off a bunch for their own internal
use, or there are a LOT of issued wDevs.  Best bet it you REALLY need
to send some specific postscript command (and I personally would frown on
it, because my printer driver would barf in your applications face) is to
limit yourself only to the wDev for a LaserWriter.  Besides, don't forget
printers like the Personal Laserwriters (not all are postscript.)  Overall,
it is generally a BAD idea to do this.

PS. If you really want to know, the wDev can be obtained from the Print
Record returned from prValidate or prOpenDoc.  Look in IM2 (I think).

    Written like a true unbeliever. PostScript is definitely worth
addressing specifically, even to the point of ignoring other printers in
some cases. Heresay to some, reality to others.
    For your average printing application, make no assumption you need not
make. Do everything in your power to work on everything, but sometimes, you
just gotta do what you just gotta do.
    Check into the picComments and use them wherever possible. If a printer
driver supports those, you should support them. Make an effort.

    If you need to image serious graphics that cannot be imaged in
QuickDraw without rewriting large chunks of PostScript, using PostScript
can be easily forgiven.
    It is not unknown in the world of PostScript illustration packages to
assume that any printer chosen is a genuine PostScript device, and that any
others are utterly beside the point. Apple and the Macintosh owe much of
their survival to such "fancy" things.
    Remember however, by doing such a thing you are cutting your market
down dramatically in order to radically improve the product for the
remaining segment. In the ideal world, you would cope with both segments.


: The problem is that you really cannot tell if the printer you are going
: to is postscript....

    You can get information about the chosen printer from within the
system file, and confirm that it has an entity type of laserwriter. The
original poster, or anyone else, could bug me to get out the specifics.

    You make the very points I was trying to convey (so it didn't really
come out that way...).  The only problem is that I beg to differ with
your last point.  You can check for a SPECIFIC PRINTER DRIVER, but not a
specific printer.  Even then, you need the wDev list because this is the
only relyable identifying mark.  Pretty much all of the rest of the
Print Record can be anything (there is NO set standard...Apple
recommends one that they themselves to do religously follow).

How about getting the PACK resource (-4096) and checking the flags
(longword at offset $C) Bit 31 determines if it's an AppleTalk device,
Bit 30 says if it uses PAP, Bit 29 says if it's postscript, and so on.
Documented (partially) in IM-IV, pp217, and in some very old MacTutor
articles.
Otherwise, you have to check the wdev in the print record, and determine
that the high byte is 3. This identifies the LaserWriter driver, which
_most_ postscript printers use.
