I'm still looking for the reboot code for an Apple LaserWriter (we're
having problems printing TeX stuff from our DECstation when the 7.0.1
drivers are installed--right now, we need to turn the thing off before
any TeX job goes thru)...

Thanks in advance.

Send:

%!PS-Adobe
serverdict begin 0 exitserver
systemdict begin quit

Note that nothing after the "quit" will be processed.  The I/O system will
enter an undefined state for a bit, while the PS reinitializes.

The serverdict... line is not necessary on level 1 printers, but the quit in
systemdict is serverloop protected in level 2, so you'd get an invalidaccess.

There are TWO quit's in PostScript: one found in userdict which flushes the
current job to end of file mark, and the one in systemdict, which (usually)
reboots the RIP.  This has been known to vary sometimes in different PS
implementations.

I've found on some newer level 1 printers (possibly including the LaserWriter
IINTX), that if you didn't exit the server loop, then the systemdict version
of quit just did the same thing as the userdict version--flush the current job.
Thus it's best to do it in all cases.

There's a sample on ftp.apple.com, somewhere inside the snippets directory,
called Windoid. It's a MacApp 3.0a2 based sample that shows how to create
tear-off
menu windoids.

Yes, I know, I should clean up the code for MacApp 3.0 final, and that's
exactly what I'm working on just now. Later (don't know when) my MouseInfo
Behavior sample should also appear on the ftp server, and this one also
has a floating window palette.

I thought I read somewhere that AUIP frowned upon changing the cursor location
on the user. (ie moving the cursor over the default button like they do
on the Sun Platform) After searching the technotes and the Developer CD's
I could not find this reference. Does this guideline exsist or am I making it
up?

I think the User Interface Thought Police didn't put that recommendation in
because they couldn't believe anyone could be that *stupid*.  But Sun
Microsystems astound the world again.  I think you can put jumping the
pointer about in the same basket as Sun's other 'crowning achievements' like:

o talk(1) still being host byte order dependent
o Sun workstations still using all zero's for broadcasts

This leads me to question whether Sun is getting technical advice from
Microsloth or vice versa (-:

I guess there's no specific guideline about this, perhaps since there's no
official system call to move the pointer.  (Pointer is the official name.)  The
closest would be the statement that users want to feel that they are in charge
of the computer's activities.

I don't remember seeing this explicitly stated somewhere, but it would
make sense for this to be a nono.  Many people would get confused if
the cursor started moving around on them.

I second this opinion.  I hate it when the Sun moves my cursor for me.
I start trying to move it and end up moving it off the button and then
back on again.  Unless the cursor is hidden because the user has been
doing something completely different, please don't move it.  The Apple
User Interface philosophy is that the user is in control of the
machine, not the other way around.

I agree whole heartedly -- the cursor should always be left completely in
the user's control. Quickkeys sequences (macros) have the cursor jump all
over the place, and it is >very< distressing!

I don't know whether it still does (and I don't have it on this machine
to check) but old versions of Excel used to move the cursor by themselves.

What happened (deduced from playing with it) was that Microsoft made dragging
the scroll bar thumbs non-linear for better control of small movements around
the spreadsheet.  It semed to be roughly quadratic: if you were in the middle
of the sheet and dragged the thumb to the 75% mark (i.e. half way from where
you were to the end) then you'd actually move a quarter of the way towards
the end (i.e. to 62.5% of the way in the document).

The problem with this is of course that now that you're 62.5% of the way
through the document, the scroll bar thumb should also be 62.5% of the way.
So when you released the mouse button they snapped the thumb back to
the 62.5% mark, and at the same time moved the mouse pointer by the same
amount so that it was still positioned over the thumb, ready to drag the
thumb again.

Now I don't know whether or not it was a quadratic law or some other
formula, but I do know that the pointer and thumb both snapped to a
different position when you released the button in the way described
and most people didn't notice it.

Vision does this (moves the pointer) when you select one of their pop-up
menu things, and what's more they put it back where it was when you exit.
It's very disorienting even when you're expecting it.

One reason that SunView and XView/OPENLOOK does this is that the Sun's screen is
to large that it is very nice not to have to find your cursor for a small dialog

I use X on a monochrome DECstation (1280x1024 -- 19" VR319) which is
slightly larger than the display on the Sun 3/60, but I only have
trouble finding the pointer if the system has moved it (e.g.,
Interleaf). Display size does not seem to be a factor for all users.

Unfortunately, I cannot find any references to formal studies on the
issue.  I did find references in the DEC XUI and Motif style guides.
Since the Motif guide is derived from XUI's, I only quote the Motif
one:
        2.2.3.2 The Pointer
        ...
        Your application should only interpret the mouse pointer
        position; it should not attempt to change it. To do so would
        violate users' trust in the consistency of your program and
        their sense of control. Also, changing the mouse pointer
        location may create problems in applications that use absolute
        location devices (like graphics tablets).

Subject: Offscreen graphics sans Color QuickDraw?
From: [e-mail]
Date: 7 May 92 15:24:35 EST
Organization: Wright State University

I'm in a bit of trouble with System 7 offscreen graphics world routines
on Macs without ColorQuickDraw.

I'm using THINK Pascal 4.0.1 under System 7.0 (tuneup 1.1.1). I create
an offscreen world and lock it without error:

  SetRect(rWorld, 0, 0, 550, 550);
  err := NewGWorld(offWorldPtr, 0, rWorld, nil, nil, []);
  locked := LockPixels(MyGetPixMap(offWorldPtr));

I call GetGWorldPixMap only when appropriate:

  function MyGetPixMap (gwPtr: GWorldPtr): PixMapHandle;
  begin
    if hasGGWPM then {according to Q & A stack}
      MyGetPixMap := GetGWorldPixMap(gwPtr)
    else
      MyGetPixMap := gwPtr^.portPixMap;
  end;

I initialize offWorld without incident:

  GetGWorld(savePort, saveGDH);
  SetGWorld(offWorldPtr, nil);
  rWorld := offWorldPtr^.portRect;
  EraseRect(rWorld);
  if hasCQD then {ColorQuickDraw only stuff};
  SetGWorld(savePort, saveGDH);

I repeatedly draw off-screen then on-screen:

  GetGWorld(savePort, saveGDH);
  GetForeColor(saveColor);
  if hasCQD then
    RGBForeColor(deltaColor);
  SetGWorld(offWorldPtr, nil); {draw offscreen}
  MoveTo(ix, iy);
  Line(0, 0);
  ix := ix - left; {translate to screen}
  iy := iy - top;
  SetGWorld(savePort, saveGDH); {draw onscreen}
  MoveTo(ix, iy);
  Line(0, 0); {<-----Bomb: illegal instruction in an 'scod' resource}
  RGBForeColor(saveColor);
  PenNormal;

This all works fine on a Mac II, IIcx, IIfx, and Classic II; it
survives heap scrambling and strict discipline; it bombs on a
Classic!? I'm pretty sure I'm not generating any 020/030 instructions.
Still, I'm doing _something_ to make the Classic think it's safe to
execute such code.

Any thoughts on this? Thanks in advance.

Great, I get to answer my own question.  (I gave up a little too early on

Boolean GetApplicationHome(short *theVolID,long *theDirID)

    Boolean retVal;

    long ourDirID;

        //// Load the return variables initially with -1

    *theVolID = (-1);
    *theDirID = (-1);

        //// Store the refNum of the current resource file
        //// (at opening time, this will be the applications
        //// resource fork)

    ourResID = CurResFile();

        //// Figure that we will be successful

Use PBGetFCBInfo (IM IV-179) with ioRefNum equal to
CurResFile().  This works nicely.

I preffer
oe:=GetVol(wdrn,nil)
oe:=GetWDInfo(wdrn,vrn,dirID,procID);

I tried using the wdrn in the GetAppParms instead of GetVol, but it failed,
anyone know why GetAppParms wouldnt work (under System 7)?

Have fun all,
   Peter.

I prefer:

err = HGetVol(nil, &vRefNum, &dirID);

not only because it's one call shorter, but also because it's in C   :-)

Remember, this call must be made _before_ doing anything that could change the
default directory. If you need to find out what directory you are in at any old
time, then the GetFCBInfo trick (like the way Jack did it in his follow-up
posting) is OK.

>I tried using the wdrn in the GetAppParms instead of GetVol, but it failed,

GetAppParms doesn't return the same information as GetVol. The former returns
the name and resRefNum of the running application. The latter returns the
vRefNum or wdRefNum of the default directory or volume.

Another way is to get the information via the Process Manager (Sys7,of course)
from the processInfo-record of the application.

Ah, but you+ll get a wdRefNum in the vRefNum parameter, so you can't
use that for testing which volume you're on. You still have to
convert the wdRefNum to a vRefNum/dirID pair and discard the dirID
from that conversion.

Why would I want to compare vRefNums, you say ? Well, I use the
"relative" feature of aliases.

Urp. I forgot about that. Well, how about letting me scrape together any last
shreds of dignity by suggesting calling PBHGetVol (I never make high-level calls
anyway). That way, you can look at the ioWDVRefNum field to get the real
vRefNum.

I know that by putting the appropriate value in the itemCmd field, a 'sicn'
resource can be made to appear next to a specific menu item; I have this
working fine. However, does there exist a similar mechanism to convince the
system to place small color icons next to items, such as it does for the
System 7 Apple menu and application switch menu?

Yes. It isn't documented. It isn't likely to be. Unfortunately, it wasn't ever
designed as something that would be used outside of Apple.

The System MDEF uses cicn resources if they are present in favor of ICON
resources.  You can create small cicn resources since cicns are of variable
size.  Thus, do the same thing you would for an ICON but provide a small
cicn of the same id instead.

Of course, this only works on color systems and on b&w systems you get the
ICON resource, I think.  Come to think of it, I haven't used a 68000 in
quite some time.  Maybe I do need a PB 100 for testing...

There is the Apple MIDI software and documentation available from ADPA.
Perhaps this is what you are thinking of.

I am sending this on behalf of a friend but you can send followups as per
normal......


I am writing a DNA sequence analysis program to teach myself TCL/Macintosh
programming. I am having problems with AppleEvents; when my application
starts it displays an about box title screen, to update the screen while
doing this I call TCL's CApplication::Process1Event.
However this routine intercepts the 'oapp' AppleEvent and creates a new
document on top of my about box, so my about box has to intercept the
AppleEvents before the application does (no problem so far just add in a
DoAppleEvent method to the About box class). The problem is that I can dispose
of the Apple Event, but I want the about box to repost them, effectively just
deferrin the events so that the application does all the required events if it
is called on by another application etc. How do I keep track of the intercepted
events to re-broadcast them.
Also does anyone have a decent implimentation of general 3D graphic view system
(my sequence analysis program requires 3D graphics for some of it's functions).

Thanks... Daniel Kortschak ;-)

You could override CApplication::Process1Event in your own code to
not accept high-level events under certain conditions.

You are making this too difficult, although so is TCL since they made some
dopey use of the 'oapp' event.

Only put up a splash screen if the application is launched, not if a document
is opened. This more completely defines when your splash occurs.  This also
means you should only put your splash screen up as a _result_ of the oapp, so
you would avoid this problem completely.

To do this, you have to override CApplication::DoAppleEvent.

I personally believe that DoAppleEvent should call StartupAction and you
should override that, but I didn't write the damned thing. ;)

Subject: Drag and Drop onto a document?
Date: 5 May 92 08:57:58 GMT
Organization: CS Department, Stanford University, California, USA


If the proper FREF resource is put into a document, will it be able to
handle apple events? I was wondering about this with regards to the
following idea:

I am using 4th Dimension, which can handle apple events when it is
running through the use of external code resources (essentially
XCMDs). I would like to be able to drop a TEXT file onto the structure
file icon of the currently open database, and have the data in the
TEXT file imported automatically.

Does this sound at all possible?

Another (silly) example of this idea: I have a document open in Word.
I drop a TEXT file onto the icon of the open document.  The TEXT file
is appended onto my open document (yes, magically, since Word has no
external code capability).

If possible, email me a copy of any followup article you post, since I
don't have the luxury of reading this forum often (except digested [ick]).

System 7 provides no support for drag-and-drop onto documents :-(

Some ideas I have on this subject are:
   Make each doc a mini-app that will check to see if it got a
drag-and-drop and, if so, open its creator and do the needed stuff with
the document that was dropped onto it. If it didn't get an apple event
it could just open its creator app and transfer it's (the
mini-app/document's) data to the creator app. To minimize memory
useage, the mini-app/doc could be a so-called "faceless app."
   Write an init to allow drag-and-drop to certain documents.

Just a thought...
