Avoiding Flicker with OpenGL View when Moving Divider of a Split View
Hi all, I have a split view arranged horizontally with an OpenGL view in the right pane (surrounded by some other stuff). When I move the divider, there is a flicker on the right hand side of the OpenGL view. You don’t get this glitch if you resize the window. It's not a major issue, just a bit annoying. Does anyone know what the split view might be doing to cause this behaviour and how I might workaround it? I have a simple test project in case anyone is interested.

BOOL takeStupidRoad = NO (search app design question)
Hi All, I have a general design question. I'm going through the latest Hillegass and Kochan programming books for the purpose of writing a simple search app. I think I've figured out a way to do this, but having no experience in programming, I have no idea if my approach is good or bad. I'd rather not take the stupid road if I can avoid it, so I'm hoping someone may be able to set me straight before I go too far down the road. So if you're inclined to take a few minutes to consider what I've written below, I'd appreciate it. In any case, good luck with your projects, David *APPLICATION DESCRIPTION:* I have a library of about 1,500 text files, about 93 MB total. The application window opens with two views: left view shows the hierarchy of folders/files, and when you click on a file, the text of the file appears in the right view, where you can read, scroll, etc. The user inputs a term into the search field, and when the search is executed, the folders/files on the left view disappear and the view is repopulated with a new hierarchy showing only the folders/files where the search term appears. Below each file will be snippets of where the term appears within the text. Click on a snippet and the right view will show the entire text of the file zoomed to where the snippet appears. For example, if the search term is "child education": *Book X* The *child education* conference focused on two age groups: 5-7 years, and 8-10 years. . . . because the *child* wasn't receiving the needed attention in her *education*, her parents decided . . . . . . and over the years the *child education* policy was broadened to include moral education and . . . *MY APPROACH*: I can load the text of the 1,500 files into 1500 NSStrings with something like stringWithContentsOfFile Then I can search the 1,500 NSStrings to locate the position of the search term within each string, then extract a range (including some words before and some words after) to make the snippets. Using rangeOfString NSMakeRange etc. *QUESTION:* Would this be a workable approach? Or is it a really stupid idea to have to load 93 MB of files into 1,500 NSStrings every time the program starts up? If not this approach, what would be more efficient? Thanks. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Threaded Server using Distributed Objects
Hi, I am implementing a simple client/server using Distributed Objects. I have a single server and a small number of clients. The clients are all on the same machine so I communicate using an NSMachPort, and use 'NSConnection' 'registerName' to register a single connection name on which to communicate. It all works fine. My only issue is that the server is not threaded - so if if one client asks the server to do something time-consuing the the request coming from a different next client will have to wait. So on to my question. I would like to implement a threaded server, what I mean is I would like to have a small number of threads so that concurrent requests can happen. If one thread is busy then the a free thread can take up the challenge. Is it possible to have this on a single named connection? If so could someone give me a few pointers or a leg-up as to how to go about this.

Re: NSTableView updating checkboxes
Hi again Graham,
I have taken some time to work on your suggestions...unfortunately I still
can't figure out how to uncheck/recheck the checkboxes by clicking on them. :-(
I understand what you're telling me about keeping 2 lists and ultimately I
will get to the point where I have to do something with the items being
displayed in my table. But for now I'm still stuck on the checkboxes. This
was your last example code with my own variables/comments:
- (void)tableView:(NSTableView*) tv setObjectValue:(id) val
forTableColumn:(NSTableColumn*) aTableColumn row:(NSInteger) rowIndex
{
id object = [filenames objectAtIndex:rowIndex]; //filenames is my NSArray
of filenames
if([[aTableColumn identifier] isEqualToString:@"column2"]) //column2 is
the identifier for my checkbox column
{
BOOL selected = [val boolValue];
// add or remove the object from the selection set
if( selected )
//how can I uncheck the checkbox??? every method i'm trying fails...
[self addToSelection:object];
else
//how can I recheck the checkbox??? every method i'm trying fails...
[self removeFromSelection:object];
}
}
In this method it's so easy:
- (id)tableView:(NSTableView *)aTableView
objectValueForTableColumn:(NSTableColumn *)aTableColumn
row:(NSInteger)rowIndex
{
if ([[aTableColumn identifier] isEqualToString:@"column2"])
{
return [NSNumber numberWithInt:NSOnState]; //initializes checkbox
column with boxes all checked
}
return [filenames objectAtIndex:rowIndex];
There's one more thing...in your first email you said I needed to set something
in IB and at this point the only thing I have set is the column identifier for
this checkbox column (column2). If there is something else I need to set in IB
I'm not sure where to set it? I'm not using bindings at this time...
Thank you for your patience Graham. Ultimately I would have my list of files
in the first column and this would not change. Then checkboxes in the second
column which would start all checked. Then the user could uncheck/recheck any
boxes they choose and when it comes to processing time only the files that have
a checked box will be acted upon. I might be going about it the wrong way but
I was just trying to get the checkbox issue working first...thanks again!

Subject: Re: NSTableView updating checkboxes
Thank you again Graham so much for the quick reply. Yes you're right about
where I'm headed. I was just thinking that I could code it that when you click
on the checkboxes the state would toggle then when I got to the processing step
I would simply read the state and know how to process each item in my array.
But I see what you're saying yes at this point I have no set boolean state in
my array. I was able to initialize my table view with "checked" boxes by
returning the ON state but in this method I got stuck because the return is
void and that's where my problem was. Ok I will work on your suggestion and I
really do appreciate all of the help... :-)
I'll let you know,

See NSAppleScript/OSAKit/Carbon OSA APIs. There's a sample project in the objc-appscript repository, CallAppleScriptHandler, that provides a simple demonstration of calling script handlers from ObjC, using appscript's AEM APIs to simplify the process of converting Cocoa objects to/from NSAppleEventDescriptors. Sorry for misleading you, i rather meant "receive events" from third party applications. If you want to run an AppleScript as a standalone application and send it events from other applications, save your script in Script Editor as a 'stay open' application. As for sending events from Cocoa(?) apps to this applet; there's a couple ways you could arrange that, but you'd need to provide more details on what the setup needs to do if you want specific advice. Or do you mean that you want to write a Cocoa application that forwards some/all incoming events to an embedded AppleScript? In that case you want either NSAppleEventManager, or possibly Cocoa Scripting, to handle incoming events, and NSAppleScript or OSAKit to host the script, and write some glue code to go inbetween. Well, I'm writing a "translation memory" application, which is a program that grabs sentence by sentence from a given text (that needs translating), asks the user to translate that sentence and stores the translation and the original in a database. If the user comes across the same sentence again in the future, he or she will not need to translate it again. I thought i would take the TextEdit app as the text editing part of my project, but as I wrote the database management and the search parts, it turned out that TextEdit is not capable of correctly interpreting word files or RTF's (ie it ignores footnotes, headers/footers and a lot of other stuff). That is why I am trying to find out how i can communicate with Word or Pages. As far as what I would want from an AppleScript (if I were to use AppleScript) is to be able to receive notifications from Word when, for example, the user has hit a certain key combination, to know where the insertion point (or selection) is in Word and to receive notifications when it moves, to be notified when a user is trying to edit something and prevent him/her from doing so if that part of the text should not be edited. Receiving those notifications, that script would just redirect them to my application and receive responses to them and redirect them to Word. In case of scripting bridge, the logic I described for AppleScript would be in my application. But having read what I found and had time to read, I'm not quite sure yet I can be notified of the things going on in another application (such as Word, for example). or set that script as a delegate of that application Depends exactly what you mean by 'delegation'. The OSA API provides a whole bunch of arcane selectors and callbacks for two- way intra-process integration between application and scripts, but whether it's appropriate/how to use it will depend on exactly what you're trying to achieve. By delegation I mean the form of delegation that is present in Objective-C, when one can register one's object with another object as it's delegate and receive messages from in on certain occasions, such as textViewDidChangeSelection: That's pretty much what the OSA API was designed to do [1] - allow a C/C++/ObjC application to load a script and invoke its handlers (what AppleScripters call 'attachability'). See Folder actions, Mail rule scripts, etc. Satimage Smile, for example, provides a great demonstration of just how far you can go with this sort of thing. HTH has [1] With the caveat that the OSA API is somewhat over-complicated, under-documented, lame in parts, and only really practical for AppleScript despite being theoretically language agnostic. -- Control AppleScriptable applications from Python, Ruby and ObjC: http://appscript.sourceforge.net ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Is it a "Value" or an "Object" ?
I've never understood the difference between our use of the words
"value" and "object".
So, last week I created a little category on NSMutableDictionary which
constructs nested dictionaries. See code below for a demo of -
setValue:forKeyPath:.
Did I name it correctly, or would this method be better named -
setObject:forKeyPath: ??
Thanks,
Jerry
int main(int argc, const char *argv[]) {
NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init] ;
NSMutableDictionary* md = [NSMutableDictionary dictionary] ;
[md setValue:@"red"
forKeyPath:@"meals.lunch.fruit.color"] ;
[md setValue:@"white"
forKeyPath:@"meals.lunch.cheese.color"] ;
NSLog(@"%@", md) ;
[pool release] ;
return 0 ;
}

Re: Send events to AppleScript
As far as TextEdit is concerned, i thought of taking its source and modifying it to my needs, and actually create a single application, not a tandem of two or more. I am even beginning to think of taking the OppenOffice as the host for my additional functionality, but OO doesn't look at all stable. Are there any libraries out there that could access all (or at least the most common) elements of .doc, docx and RTF documents besides NSDocument? It doesn't really matter if they can render page layout correctly, the important thing is that they could access and modify those elements.

NSAppleScript - what is going on here?
Folks;
I'm trying to get a string value back from a simple AppleScript in
Cocoa:
NSDictionary *errorDict= nil;
NSAppleScript *appleScriptObject = [[NSAppleScript alloc]
initWithSource:theScript];
NSAppleEventDescriptor *eventDescriptor = [appleScriptObject
executeAndReturnError: &errorDict];
[appleScriptObject release];
if (([eventDescriptor descriptorType]) && (errorDict==nil)) {
return [self stringFromAppleEventDescriptor:eventDescriptor]; //my
own method that checks descriptorType and returns stringValue
} else {
NSLog(@"%@",[errorDict objectForKey:@"NSAppleScriptErrorMessage"]);
return nil;
}
The 'theScript' is a valid script that executes flawlessly in 'Script
Editor':
tell application "Finder"
try
comment of file ("/Users/steve/" as POSIX file)
on error
return "Error"
end try
end tell
The problem is that the above errors out @ [appleScriptObject
executeAndReturnError: &errorDict];
The stack is shown below.
What am I overlooking here?

MacRoman -> UTF8
My software uses UTF8 almost exclusively. However, for some odd reason, arguments passed from a perl cgi script to one of my command line helper apps are encoded as MacRoman. That's not a problem since I can just use [NSString stringWithCString:argv[i] encoding:NSMacOSRomanStringEncoding]. However it seems that one can't convert MacRoman -> UTF8 after you get it into a NSString. Is there a way to make this conversion in code so that once I read the arguments I can just deal with them like all the rest of the strings in my app? Another viable solution would be a way to make the arguments passed in UTF8 since they are when they're handled by the script anyway--they must be getting changed somewhere in the bowels of the exec/system commands.

NSLevelIndicator Bindings Crash
I'm using Core Data, and I have an entity; we'll call it "Item". It has an attribute called "priority". In the xib, I have an NSLevelIndicator and NSStepper. I have a NSTableView full of "Items". Depending on which item is selected in the table view, I want the level indicator and stepper to display the right values, and for me to be able to set them to a certain value for each item. There are 2 problems: If I bind the value of either one to Item.arrangedObjects.priority, the app throws an exception, whereas if I bind to Item.selection.priority, the controls don't set each item's priority individually. What should I bind to? Secondly, an NSLevelIndicator wants a float for its value, whereas an NSStepper wants a double for its value. Which should I set it to in the core data model?

What is -launchApplication:'s "name of the application"
From NSWorkspace documentation, - (BOOL)launchApplication:(NSString *)appName Parameters > appName > The name of the application to open.

Re: What is -launchApplication:'s "name of the application"
I was just thinking about the Discussion in the documentation some more, and it implies that the name would be the name of the .app package in the filesystem. So, that might be the answer, but then, this is going to break if the user changes the name of the package.

Why isn't NSString's caseInsensitiveCompare working correctly?
Odds are, it's a bug that is based entirely in my code, but it's bugging me
now, and I've hit a road block mentally. Any help provided would be greatly
appreciated.
Please excuse the crypticness of this message, but I'm only able to disclose
the parts of the code in question.
The basic overview of what's happening in the code is [classInst
findIndexOfFilename:inData:] is being called, with the filename being passed
in from a directory enumeration. A manual browsing through the data makes it
look like all aspects of it appear like it should work.
If anything further needs to be known, just let me know, I'll likely be able
to provide.
At the moment, I'm pretty sure it should work by the looks of it. What's
really bothersome about it to me is that the output of the first error shows
that the entry at 10:28:17.401 is the only entry that is outputted by
findIndexOfFilename:inData:, and none of the subsequent entries are
presented as having been checked. *scratches head*
First failed output record in the XCode console
[Session started at 2009-03-21 10:28:17 -0700.]
2009-03-21 10:28:17.400 IX2[52319:10b] "Contents"
2009-03-21 10:28:17.401 IX2[52319:10b] "Contents" != "Contents"
2009-03-21 10:28:17.407 IX2[52319:10b] Hmm, it appears that "Contents" is
not in passed data pointer. pname=<>/Contents
The code to find the index -- before this is called, the caller is
currently calling NSLog(@"%@", fn);
- (int) findIndexOfFilename:(NSString*)fn
inData:(S_KH_DATA*)data
{
int ctr = 0;
NSString *s;
// this would indicate a failure in our build process
assert( data[0].filename != NULL );
do {
s = [NSString stringWithCString:data[ctr].filename
encoding:NSUTF8StringEncoding];
if( [fn length] != [s length] ) continue; // don't go and do a full
compare if diff lens
if( [fn caseInsensitiveCompare:s] ) break;
NSLog(@"%@ != %@", fn, s);
} while( data[++ctr].filename != NULL );
if( data[ctr].filename != NULL )
return ctr;
return -1;
}
The structure that is the data[x]
typedef struct _S_KH_DATA
{
uint8_t fs_type; // 1 is directory, 2 is plain
file, 3 is executable file, 0 is unset/ignore
char *filename; // filename is the name of the
filesystem
uint8_t hash[SHA512_DIGEST_LENGTH]; // sha2-512
} S_KH_DATA;
The data being passed (first entries only, abbreviated)

{ KHD_TYPE_DIRECTORY, "", 0 },
{ KHD_TYPE_DIRECTORY, "Contents", 0 },
{ KHD_TYPE_DIRECTORY, "Contents/MacOS", 0 },

nstableview **very** basic question
I've been struggling with this for a few days...so time to ask, if I
may.
I am trying to emulate Scott Anguish's multiplication table in his
book. I cannot get tableview to show columns of constant width.
I have looked at the guides of Apple, tried to understand all the
nuances of tableview, scrollview, headers etc, looked at numerous
tutorials on NSTableview, (most a little dated), discerned that
perhaps I should be looking at NSTableColumn, and thought I had found
the answer doing this.
-(void) awakeFromNib
{
NSLog(@"awakeFromNib: setting \"sizeToFit\"");
[tv sizeToFit];
}
where tv is declared as: "IBOutlet NSTableView *tv;"
As far as I can tell, the outlet is set correctly, NSLog is called at
the appropriate time.
What I get when I use the above code is the first couple of columns
varying in size, then the next "n" columns equally space.
If I have missed something in the documentation, I would appreciate a
pointer, but somehow, I cannot believe that it is this difficult to
do, but perhaps I am doing something that will become a lot easier
further into Hillegas tutorial?
Thanks in advance.

Re: Why isn't NSString's caseInsensitiveCompare working correctly?
if( [fn caseInsensitiveCompare:s] ) break;
NSLog(@"%@ != %@", fn, s);
compare methods return NSOrderedSame (==0) if the strings are the same so
your test here seems incorrect.

UTF-8. See the last bit of my post, seemingly they're being

That's not a problem since I can just use
[NSString stringWithCString:argv[i]

I don't know what you mean by "convert MacRoman -> UTF8 after you get
it into a NSString". After you get text into an NSString it is, by
definition, no longer MacRoman.
Thats what I thought. However, say I start by reading "bén" as I
noted above, then I call printf("%s", [myStringReadFromMacRoman
UTF8String]) and it prints "bÈn". However if I call printf("%s",
[myStringReadFromMacRoman
cStringUsingEncoding:NSMacOSRomanStringEncoding]) is prints out
correctly. Now I'm thoroughly confused and am not sure what's
happening. Any more thoughts?

Is there a way to make this conversion in code so that
once I read the arguments I can just deal with them like all the

Another viable solution would be a way to make the arguments passed

What does printf( "LANG = %s\n", genenv( "LANG" ) ); say? For example,
on 10.5.6 with Terminal set to UTF-8 I get:
LANG = en_US.UTF-8
If I change it to MacRoman or Latin-1 then I get just
LANG = en_US
If you need to change your terminal settings, it's "Preferences... "
-> Settings -> (choose your default) -> Advanced -> Character
encoding.

NSString and Leaks Instrument, False Positives?
Hi everyone, I'm auditing my app and the both the "leaks" command line tool and the Instruments tool are both reporting that I have NSString leaks. All of the leaks are coming from code similar to the following: NSFont *ageStarTextFont = [NSFont fontWithName:@"Arial Bold" size:KRLesserDimensionOfRect(transientDrawingRect)/3]; I'm guessing that the string in question is the @"Arial Bold" since it that is the only string on that line, but from what I understand a string created like that doesn't require a -release message. Could these be false positives generated by the leaks tool, or is there something that I'm missing? Thanks for any pointers!

be careful with clang, sometimes is missing point, your problem is coming not from this @"Arial Bold", give the complete stack and explain what is the condition of the leak False/positive: I have an extensive use of perf tools since years and I didn't see that since a while the leak can be deeper than your app === give the complete stack-trace On Sat, Mar 21, 2009 at 4:43 PM, Kevin Ross wrote: > Whoops, I thought that I'd also mention that I've run the code though the > clang static analyzer and it doesn't report that there are any bugs.

Did I guess correctly? You're correct that it's ambiguous, not only because applications can have several names, but because several applications can have the same name. The answer here is not to use this method at all. The bundle ID is the proper way to uniquely identify an application, use a method which takes that instead.

All this means is that whatever is displaying your printfs expects
MacRoman encoding rather than UTF-8 encoding. Since we don't know
what's displaying them, it's hard to say anything further.

Trust me, there's nothing inside of exec that would do this.

Maybe you have. The documentation for -[NSTableView sizeToFit] says:

Explicit release when using garbage collection with circular references
Is there any issue issuing explicit release when using garbage collection with Leopard and Obj-c 2.0? I've become aware that I have lots of memory not being freed within my application. I presume this is because its a tree structure with parent child pointers between the objects. If I drop the last reference to the tree, I presume the tree does not get garbage collected because each object has circular pointers between them, ie parent has references to children and each child has a reference to its parent. In this case, it seem that the appropriate course of action would be to call a specific method to forcibly release each node in the tree. Is this the proper approach? Should garbage collection somehow work anyway? Thanks ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Your sub-graphs -- trees -- of objects that are no longer referenced by your rooted object graphs should be reaped without a problem. So, something else is going on.
