I've been using THINK C for a while now, but I'm just now getting into the
Class Library.  In my normal C programming, I make extensive use of popup
menus.  However, I don't see a CPopupMenu, or any obvious way of using the
existing menu support to make popups.  Am I missing something obvious?  Is
there a CPopupMenu somewhere out there?  If not, would anyone want one if I
wrote it?

Thank you, all who responded to my post above.  CPopupPane was right under my
nose, in the TCL Folder!  The confusing thing is that it is not mentioned
anywhere in the OOP manual.  The subclasses of CControl are listed as
CScrollBar and CButton (which in turn has subclasses CCheckBox and
CRadioControl).  Now I can understand not documenting classes like CStaticText,
which is supplied for compatibility only, but something as useful as CPopupPane
should really be findable without doing a Finder search!  What's up here?

Actually, it is not the key bindings that I miss about emacs, but
the modes.  Especially the [electric | eclectic] [C | C++] modes.

I tried to program them into MPW a while back using the SetKey function,
but it was just too limited.  For example, in one of those modes,
if I begin a line with:

#in

emacs would give me:

#include "|"

(the | is the insertion point).  This saves a LOT of typing.  It did
several other things to save my poor wrists as well, and I could customize
its auto indent based on how *I* liked to view my code.

All of this is impossible to impliment from within MPW.

Another very usefult feature of emacs is the ability to compile common
scripts.  I would really love to be able to compile my startup scripts.
With the frequency that I have to reboot, that alone could save me
probably 30 minutes / day.

True, I like macros as well, and Object Master actually provides something
similar.

True again, the only way to speed up things in MPW today is to convert scripts
to tools, something which I support with scripts which are used
over-and-over-and-over-and..

Subject: Quicktime Question (Standard Compression Dialog)

Hello,
I have been looking for a documentation of the StandardCompression
Utilities (Those QuickTime routines starting with SC...) that are
used in some sample code onthe QT CD-ROM. It seems it is not in the
docs on the CD ROM. Also there is no statement if it is legal to use
the resources in the sample projects (THINK C). Anybody more informed
than I am ?

The Standard Compression component is documented in an Inside Mac Viewer
file called "StdCompression" in the same folder where the std compression
.h, sample code, and resource files sit on the QT 1.0 Dev CD.

My understanding is that this component will be rolled into QuickTime itself
in the future. The glue code checks if there is already a 'scdi' component
registered with the system, and if there isn't, it registers and calls the
one in the Application. You probably are free to use it in noncommercial
programs, but you might need to license it (as part of QuickTime) for
commercial distribution (I think Apple charges $50 a year or so for all of QT).
You should probably contact them.

Hope this helps,

There must be a "central" depository for TCL classes like this;  if not there
should be, I bet we could all save ourselves a lot of work by browsing through
stuff that others have written...

Anyone know of such a place or volunteer to set one up?

The official Think C ftp site is ics.uci.edu, directory /mac/think-c.
Symantec and others (?) distribute sample code and goodies here. I don't
know what the upload policy is. However, may I suggest that interested
parties join the tcl-talk mailing list? The subscription address is
[e-mail]. There is an associated ftp site, ftp.brown.edu,
where digests and contributed classes are archived. I know there's a set
of popup tear-off menu support classes there -- I contributed them. (There
are some distribution restrictions, pending polishing, since it's still at
the beta stage.) The dialog classes shipped with TCL 1.1.x also include
a popup menu class. I haven't played with it -- I wrote mine before TCL 1.1
came out, and it handles rather more than just text menus. If you want
the system-7-standard behavior, though, with the little arrow and whatnot,
check out Symantec's class. Mine was written for tool palettes and behaves
differently.

Actually, there is a TCL list, which you can join by sending a message to
[e-mail]. The list accepts articles at [e-mail] and
it also has an ftp site at ftp.brown.edu, in directory /pub/tcl. You can
ask how to submit classes by a message to [e-mail]. As far as
I remember, there was something done on pop-up menus.

Check the gdFlags for the GDevice in InsideMac V-131.
If bit 0 = 0, then you are in grayscale (IM says mono, but
it really means grayscale from what I've seen), and
if bit 0 = 1, then you are in color.

Okay, when I run this code, THINK C tells me that gConnection is equal to
0x00000000. But it won't execute ExitToShell! Is this incredible stupidity
on my part or something going wrong? (I'm assuming the former for now...)

    procID = CMGetProcID("\pAppleTalk ADSP Tool");
    gConnection = CMNew(procID,cmQuiet+cmNoMenus,sizes,666L,666L);
    if (gConnection == NULL) {
        ExitToShell;
        }

Just as an aside, this code was working fine until I changed *something* (which
I can't remember).

Thanks,
Ed

It may not exit to shell, but it might just put $A9F4 in the low word

  Following is some sample code that is a class based on CResFile.  It
implements a preferences file for TCL under System 6 or 7.  I make no
claims other than it works for me, and no guarantees except that you'll
have to modify it to work for your individual needs.

class CPrefResFile : public CResFile {

 public:
     void    IPrefResFile(void);
     void    Dispose(void);

     void    Open(SignedByte permission);
     OSErr    GetPrefFile();

};

    CResFile::IResFile();
}

void    CPrefResFile::Open(SignedByte permission)
{
    Boolean wasLocked;

    ASSERT( IsOpen() == FALSE);

    wasLocked = Lock( TRUE);
    refNum = HOpenResFile(volNum, dirID, name, permission);
    Lock( wasLocked);

    if (refNum == -1)
        refNum = 0;
}

OSErr CPrefResFile::GetPrefFile()
{
    Str63        temp;
    OSErr        err = 0;
    short        lVolNum;
    long        lDirID;

    }
    else {
        err = FindFolder(kOnSystemDisk, kPreferencesFolderType,

    inherited::Dispose();
}


OSErr    CPrefResFile::MakeNewPrefFile()

    Handle    prefsHandle;
    FInfo    finderinfo;
    OSErr    err;

    CreateNew('CREATOR_ID', 'PREF');
    Open(fsRdWrPerm);
    prefsHandle = NewHandle(sizeof(struct Preferences));

    ReplaceResource(prefsHandle, 'PREF', rStdPrefs, "\pStandard Prefs",

    thePrefs = (struct Preferences *) NewPtr(sizeof(struct Preferences));

    thePrefs->in_conn = kICWait;
    thePrefs->sess_man = kSMConditional;
    thePrefs->numShortcuts = 0;
    strncpy(thePrefs->name, shortName, NAME_SIZE);

//    Create the pref file object
    prefFile = new CPrefResFile;
    prefFile->IPrefResFile();
//    Get the prefRef
    prefFile->GetPrefFile();
    prefFile->MakeCurrent();

//    Now get the Preferences from the file
    prefsHandle = GetPrefRes('PREF', rStdPrefs);   // *** Sorry, I can't
give you the code to GetPrefRes.  It's not mine to give, but it
basically does a Get1Resource with wrapper...
    if (!prefsHandle) {
        ErrorDialog("Problem with the preferences file.", 0);
        return FALSE;
    }
    else {
        BlockMove(*prefsHandle, thePrefs, (Size) sizeof(struct Preferences));
//        ForgetResource(prefsHandle);
//        FailResError();
    }
    prefFile->Close();

You should contact APDA.  Apple acquired the rights to XTND from Claris
last year and started shipping the XTND Developer Kit in August.  The kit
is $30 and includes the license.  It really doesn't take much code to
support XTND, sample programs supporting XTND are included in the package

providing an XTND Class for MacApp, but it is pretty easy to add XTND

I don't know whether anything ever came of it.

I'm not sure where XTND is going, and would recommend that you hold off
for the moment.  For gamblers, the XTND 1.3 package from APDA will probably
be pretty compatible with any (definatively _unannounced_) future versions.

I wrote an XTND package for MacApp, which has been mostly used in 2.0, but
also had the headers ported to 3.0/C++.  It provides an easy way to read in
both text (into TEViews or chains of TEViews) and pictures via XTND.  We use
it in the PREP Editor.

I think Tom Chavez knows about it (I certainly tried to tell him) but I have
never had any conversation with him about it.

Subject: How to get KeyDown event without WaitNextEvent
Date: 19 May 92 20:59:33 GMT


Someone please help me with this...

   Can I get a Keydown event without using WaitNextEvent function?  The
reason why I want to do that is becasue my program clears the whole screen, and
when I call WaitNextEvent to get user keyboard input, the menu bar gets redrawn.
But, I don't want to redraw the menu bar!  If this can't be done, can someone
tell me how to tell WaitNextEvent not to redraw the menu bar?

   Please don't flame me if this is a stupid question.  Thank you very much
for any help in advance.

Not really, but you can look at the keymap by using the
GetKeys(var k:KeyMap); call . This will return in the kemap array flags
telling you which buttons are being held down.

Are you writting a game? You will probably need to hide the menu bar. Or as
Tog says  "change it to the same color as the background."

The only stupid question is the one not asked. :-)

  I am using a program that changes the name of files..  I have noticed that if
I try to delete a file that has had its name changed, and the window containing
that file was open during the change, I get a file not found error.  However,
if I then close the window and the open it again, it deletes it no problem..
  Is there a special message that I want to send to the finder whenever I
try to change a file that will update the finders name lists?

The Finder caches tons o' stuff now.  You can get it to flush its cache by
changing the modification date of the containing folder (i.e. the open
window).  This will make the Finder update the window.

1. The Numerical Recipes disk(s) contain a 2D FFT (f77, cc, pascal).
2. I believe there are also public domain FFT codes (f77 and cc) in netlib.

You may get more responses if you post to "sci.math.num-analysis".

Better yet, write your own!  There are many algorithms; I have found these
sources the most useful:

"Numerical Methods for Engineers", Chapra and Canale, 2nd ed., McGraw Hill

"Algorithms in C", Robert Sedgewick, Addison-Wesley

Also, for more FFT info, read various articles in the ACM journal by Cooley,
Tukey, and Sande, although this gets pretty thick.

Try Rich Siegel's excellent freeware editor BBEdit, which you can
find at sumex-aim.stanford.edu, under info-mac/app. Maybe you might
alsolike to use it as an editor, in addition to grep'ping with it. :-)

I use the MPW command string:

search /STRING/ `files -o -f  -r -t TEXT "DIR"`

This will find STRING in all text files in the directory DIR.
If DIR is omitted then the current directory is used. I'm sure
if you wanted you could emulate the unix grep command by using a
script that munged the grep parameters into the search commands
needs.

Why not use the filename explosion stuff built into the shell?
I have these lines at the top of my worksheet:

Search -i /PBGetCatInfoSync/ "{CIncludes}"?*.h
Search -i /SFSaveDisk/ "{PInterfaces}"?*.p
Search -i /windowkind/ "{AIncludes}"?*.a

Whenever I need to find something in the includes I type it over the
text between the slashes and execute it.  There is actually a single
symbol that can replace ?* but it is one of the macintosh above-ascii
symbols and so I cannot quote it here...
