I didn't really decide I shouldn't use a run loop for the timers. I am porting a library from another platform and just wanted a quick answer if I could get a similar timer API behavior in either Cocoa, Core Foundation or BSD Unix (with a preference on low-level for efficiency), What make you think lower level mean more efficient ? Just do it the simple way (CFRunLoopTimer) and if it not efficient enough (after profiling, and testing), think about an other way to do it.

Core Data request predicates and to-many relationships
If there are any NSPredicate gurus out there, I'm scratching my head on this one: I have an entity that can optionally have a set of attributes (name- value pairs). This is set up in the model as a optional to-many relationship to an attribute entity. Now, I want to fetch the list of managed objects of this entity whose attributes exactly match a dictionary that is passed. The predicate for this needs to filter the objects that have all the required attributes; matching both the name, and value for each attribute. At this point I'm not seeing how you can code this in a predicate. If I AND some clauses like: ...ANY attr.name == %@ AND ANY attr.value == [EMAIL PROTECTED] for each attribute I'm testing for, then AFAICS I'm not testing that the _same_ attr has the name and value. I wondered about: ...ANY (attr.name == %@ AND attr.value == %@)... but this doesn't appear to be legal syntax. I'm still experimenting, but if anyone knows how to express a query that allows multiple clauses on the _same_ entity across a to-many relationship I'd appreciate a clue!

Re: Fix Populated NSMenu Of Files, Folders And Their Respected Images
thanks ashley, you cleared up a lot for me. however, i'm now presented
with two (seemingly) small issues. the first is determining whether

Hi.
i've been on this task for almost a week, and i still can't get it
right. basically, i would like to have an NSMenu populated with all
the files and folders of a specific directory. for this example i'll
use ~/Documents. the code below only partially works. it will list
files and folders from Documents in an NSMenu, but they are not
selectable. i've added a @selector, but it doesn't seem to be called.
the selector if just an example method - i don't want to really
terminate the app when an item is selected, i simply want the item to
launch.
You have to also call setTarget: on the menu items so it knows which object
to send the message to. In your case you'd probably pass self as the object.
Also if you want to access the path again during your selector it would
probably be easiest to set the path for the item as the representedObject.
NSMenuItem *item = /* your item with @selector */
[item setTarget:self];
[item setRepresentedObject:[documentsDirectory
stringByAppendingPathComponent:fileOrFolder]];
Then in your method:
- (void)actionMethod:(id)sender {
id fullPath = [sender representedObject];
/* do something with fullPath */
}
second, it would be ideal to have the folders also produce their own
NSMenu list of files contained in them - i have no idea how to do
this.
You'll have to do some refactoring to accomplish this. Essentially, break
apart your method into one that creates a menu for a directory's items and
returns the resulting menu. That method will call itself to create menus for
subfolders which you would add as subitems to your menu. You would then just
call that method on your root directory, Documents in your case, and add the
resulting tree of menus wherever you're interested in.

NSOutline view contents getting grayed

I handle this by subclassing the outline view and implementing:

{
[super highlightSelectionInClipRect:clipRect];

Here I'm just using the selected text colour the user has set in the

Also, in 10.5 there were some new methods added that allow you to set
a highlighting style which might make this approach unnecessary, but
off the top of my head I don't know exactly the details as I'm not at

MDQuery and searching within application package
My app has a number of document templates stored within the application package. The app adds these document templates to the metadata store itself via mdimport. Spotlight correctly locates and identifies the document UTI. When querying these documents with MDQuery - setSearchScopes: [NSArray arrayWithObjects:appPath, nil] I get zero results. Experimenting with Spotlight and mdfind -onlyin seems to suggest that even if data exists within the store you cannot query the package directly. However, results can be obtained by querying the applications enclosing folder. Is there a way to query the package and its subfolders directly? I have come across the com.apple.package UTI but am not certain if it is of any relevance to this situation.

You can probably simplify this a bit by using
stringWithContentsOfURL:encoding:error. Note 'encoding' and not
'usedEncoding'. The former allows you to specify the encoding. In
this case, use the constant NSISOLatin1StringEncoding (which is
ISO_8859-1).
Side note. Some parsers are especially picky about encoding names, so
best to always use the constants. The official string for this
particular encoding is ISO_8859-1. Some parsers allow aliases or
modifications as well (hyphens, lowercase, etc.)
Then, feed the string (which is now properly decoded) into a new XML
doc for parsing:
NSXMLDocument* theXMLDoc = [[NSXMLDocument alloc]
initWithXMLString:theString options:myOptions error:myError];
//do work
[theXMLDoc release];

Re: NSOutline view contents getting grayed
Hi
What ever suggested by Graham has worked for me.
Now i have one more problem where i am unable to turn on the text color to
white upon selection in the outline view.
Any idea?
Thanks

Hi,
Thats correct.
But in My application i have a table view in which i need to take some
actions.
In short i can say that My application should behave like iTunes where in
it just slightly changes the color of selected playlist in oulineview but
still allows doubl-click and slection highlighting on the table view.
I think what you'll have to do is use a custom cell for the table view.
any idea?

You can refuse to resign the first responder status by overriding -
(BOOL)resignFirstResponder
and returning NO
Except that is likely to cause the rest of your user interface to stop
working in a useful way (i.e. text fields etc can't become key).

Hi All,
I am writing a coca application in which i use NSOutline view for
Navigating
between different view like iTunes.
So when i am clicking on the ouline view contents, the contents are
highlighted in the blue.
If i click on any other view other than the ouline view, ouline view
content
which i had chosen is becoming light gray colour.
Is there any way in which i can still retain blue colour in the selected
otline view content?
I handle this by subclassing the outline view and implementing:
- (void)highlightSelectionInClipRect:(NSRect) clipRect
{
[super highlightSelectionInClipRect:clipRect];
NSRange rows = [self rowsInRect:clipRect];
if( NSLocationInRange([self selectedRow], rows))
{
NSRect sr = [self rectOfRow:[self selectedRow]];
[[NSColor selectedTextBackgroundColor] set];
[NSBezierPath fillRect:sr];
}
}
Here I'm just using the selected text colour the user has set in the
system prefs, but you can use whatever you want.
Also, in 10.5 there were some new methods added that allow you to set a
highlighting style which might make this approach unnecessary, but off the
top of my head I don't know exactly the details as I'm not at my main
computer.

Document package
Hi,
I'm trying to make document package using NSFileWrapper. I could contain a
regular file in the directory (document package), but the directory can't
change its appearance, this is, it still looks a folder, not the icon I have
specified in my info.plist.
I have also set LSTypeIsPackage of the document type to TRUE.
I did like the following:
- (NSFileWrapper *)fileWrapperOfType:(NSString *)typeName error:(NSError
**)outError
{
NSFileWrapper * result = [[NSFileWrapper alloc]
initDirectoryWithFileWrappers:nil];
NSData* data = [self dataOfType:typeName error:outError];
[result addRegularFileWithContents:data preferredFilename:@myData];
return result;
}
Would you tell me what I'm missing?
Any suggestions would be appreciated.

Re: Questions about [NSApplication run]
What about spawning a secondary thread which uses select (or kqueue, which is pretty easy to use BTW) to block waiting for events, without a timeout. When select (or kqueue) returns an event(s), then use: [yourAppDelegateOrControllerOrWhatever performSelectorOnMainThread: @selector(handleFactorEvent:) withObject: yourCustomEventDescriptorClass waitUntilDone: NO] That's the simple version. In my own code, the bg thread actually invokes in the bg thread a method on my app delegate that creates the event instance and puts the event on a queue (std::vectormythingy with appropriate locking) before calling performSelectorOnMainThread which will pull events out of the queue until there are no more.

It's a little bit of work but the end result works fine. In -

Unless you actually want a 'custom' resize image, you can use the
real

If you wanted to draw the standard grow box, you could use
HIThemeDrawGrowBox(). Relying on that file being at that location
is fragile.
But...

That's not at all what you asked. :) Perhaps you could clarify? To
change a window's size you can use the setFrame... methods.

Re: What are the limitations of Dot Syntax?
Namaste! I'm going to add my two cents here (despite being a noob). I like the dot syntax. Why? (and before I go any further, I realize this is not a Windows forum, and also realize this is a very general set of statements and quite open to debate) Because, in the Windows world at least, the dot allowed you to refer to *members* of an object. What are members? They are attributes of the object. In programming simplicity, they are: properties or methods. So, what's wrong with the dot syntax? Nada in my book. A fuller implementation of the dot syntax is more desireable in my book. From whence I came, it sure made code very much more readable and quicker to write. That being said, I don't have an issue with the way things are, nor do I really care much how they evolve, provided the evolution is for the better. The bottom line, as long as your code is readable, digestible, consistent, and clearly commented in tricky spots for those who come after you (and yourself later down the road too), it really doesn't matter, does it?

Cleanup inside a failed init method
Hi
I'm writing my own socket class using a bunch of BSD functions and am
a little unclear on exactly what I should be doing to insure
everything is cleaned up if any of the low level functions fail. If I
return nil from my init, does the system call my dealloc method to
allow proper cleanup? Or do I have to do the cleanup before returning?
Here's what I have so far
- (id) initWithHost:(NSString *) inHost
port:(int) inPort
error:(NSString **) inError
{
id result = nil;
self = [super init];
if (self)
{
host= [inHost copy];
port= inPort;
// if any of the following fails, I want to cleanup
// completely before returning
// am I doing that correctly?
// host and error are the only Cocoa objects
// I'm holding on to. The other stuff is from the BSD functions
if ([self getAddress]
[self createSocket]
[self connect]
[self updateStream])
{
result = self;
}
else
{
freeaddrinfo(addressInfo);
close(socketFD);
*inError= [error copy];
[error release];
[host release];
}
}
return result;

Re: Cleanup inside a failed init method
It's a matter of preference I guess. In practice, I can't think of any reason to connect to a server unless you intend to talk to it, so I just wrapped up all the ugliness into a nice simple interface. Creating one of my KClientSockets, connects to the host and retrieves any handshake data automatically.

Re: Cleanup inside a failed init method
Hi Chuck,

The system will only call dealloc if the object is released.
Happily, the object should be released anyway if you plan to return
nil since otherwise you'll leak a half-initialized object every time
the method fails. So you should release self and return nil.
I'm not sure about that. Take a look at this example:
// init only modifies an already allocated buffer.
// ObjC and the O/S does not know what you are going to name your
'init' method:
- (id)initIthMyParameters:(int)aParameter
{
self = [super init];
if(self) // only if super returns a valid buffer
{
parameter = aParameter;
}
return(self);
}
ob = [[MyObject alloc] initWithMyParameters:3];
The result of [MyObject alloc] is passed directly to
initWithMyParameters:.
If alloc fails, it sends NULL as object to init. [NULL init] returns
NULL, no matter which object it is, so does [NULL sniff_sniff].
-However, if +alloc succeeds, you have a buffer, it's passed directly
to initWithMyParameters:.
You're not guaranteed that you will get the same buffer that [MyObject
alloc] returns, because -init* will be able to deallocate it and
return a different (maybe even larger) buffer instead, and perhaps in
a different memory zone.
Who/what is supposed to deallocate the allocated buffer between the
[MyObject alloc] and [myObject init] ?
(How would the 'system' know that the object is to be deallocated?)
The only reason would be that the line...
self=NULL;
...should automatically deallocate the object, and I've never heard
that it did.
The general rule is: Whatever mess you create (inside your method),
you have to cleanup yourself, noone else is doing it for you.
-But if you return NULL from -init, you *must* deallocate self first,
or you will leak memory.
Love,
Jens

Re: Various syntax errors and ICA kit
Namaste!
OK, after much beating of head against wall, I found the issue.
'Twas the way the #import statements were set up. Once I moved the
Cocoa Carbon imports to the header file that cleared up quite a bit
of my issues. Also, I believe I had some of my own ignorance tossed
in as well. Made one heck of a salad...
Peace, Love, and Light,
/s/ Jon C. Munson II
Quoting [EMAIL PROTECTED]:
Namaste!
Also, if I take out the #import statement from the .m file, I get a
compiler warning about a forward class. I don't know if that means
anything truly important or not (but that was when i figured I forgot
the #import part). If I can ignore that, then I may get my app to
compile and run properly...
Peace, Love, and Light,
/s/ Jon C. Munson II
Quoting [EMAIL PROTECTED]:
Namaste!
And so the fun ensues...
I'm working with the (slightly, deprecated in 10.5) older ICA (as the
newer doesn't work).
I've brought over the code base from the SampleScanner application in
the Carbon-ImageCapture-Examples folder and applied it to mine own
form.
Before I attempted to integrate it fully into my app (meaning, actually
call it from the form that needs to call it), the nib controller
files compiled just peachy (no errors, just deprecation warnings
mostly).
So, I added it to my calling window (instantiated the class, #imported
the header, and so on) and created a method a button could trigger.
Now, however, my application won't compile. It complains of syntax
errors in the ICA form's header file:
Syntax error before ICAObject
Syntax error before ICARegisterEventNotificationPB
Syntax error before ICAScannerStartPB
Fatal error: method definition not in @implementation context
If I take the header import out of the .m file for the calling window,
and comment out the calls to the ICA window, the app compiles fine and
executes ('course, I can't load the ICA window :( ).
My ICA window is identical (with the exception of an icon image at this
point) to the SampleScanner window. The .h .m controller files are
also identical (except for log, which I removed as I don't need/want
that part).
Anyone got a clue on this?
I almost have this hooked in...so close...
Thanks!
Peace, Love, and Light,
/s/ Jon C. Munson II

I love a challenge :) It's an interesting problem and I'm learning how to use sockets. I wouldn't have even thought of bypassing the library, but I stumbled across this really cool flash library that connects to MySQL completely via sockets (http://asql.mooska.pl/release/srcview/) and thought it would be cool to do something like that in Cocoa. The MySQL protocol isn't all that difficult. I found a good resource here (http://forge.mysql.com/wiki/ MySQL_Internals_ClientServer_Protocol) The trickiest part seems to be scrambling the user password with the seed MySQL sends in the handshake. I already wrote a nice, simple packet parser to handle the different types of MySQL messages and am working my way through the password stuff. What I'm writing will be installed on about 50 to 100 machines and I have no interest in installing the client lib on all of them. I actually got some code working with the client lib but it broke as soon as it was installed on a different architecture (PowerPC) and OS version (10.4 vs 10.5) These four combinations of OS and processors are a given and I can't do anything about that. Each configuration requires a client lib specifically compiled for it and I don't want to support 4 different versions of my app or the support calls when they do a clean install or an upgrade and suddenly my app stops working. With my own sockets, I'll only ever have to worry about MySQL protocol changes which are much less frequent than MySQL updates. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSPredicateEditor and date comparisons
Hi all, In my application, users have the option of comparing to a date in an NSPredicateEditor. For the NSDates it is comparing against, only the date is important; time doesn't matter. The interesting thing I found about NSPredicateEditor is the NSTimeInterval it compares my NSDates to has the time set to 13:41:40. That means my NSDates with the default 12:00:00 time don't match an is predicate. It's not a big deal because I can just change my NSDate's time to 13:41:40 to fix the problem. But what I'm wondering is if this is guaranteed to always be true. I couldn't find it anywhere in the documentation.

XCode 3.1.1 Cocoa App template project leaking memory
Hello all, it turns out that my application has been leaking a small amount of memory shortly after launching. I looked at the code and there was nothing obviously wrong, and yet Instruments (well, Leaks) tells me that it leaks. I then commented out all the code in all the awakeFromNib methods and in applicationDidFinishLaunching:. These are the only entry points in my app and, yet, Instruments still reports the same leak. On a hunch, I decided to create a new project and run Leaks on it. I just chose a new Cocoa Application project, built it with no changes of any kind, then ran it under Leaks, and it leaks the same amount of memory as my app, and the same objects are being leaked: 144 bytes of NSPathStore2. Just thought I'd pass this along for others to comment on and, perhaps, try on their own computers.

NSImageView gets stuck
Hi, All:
I have an NSImageView (in a variable called ball) that I am trying to
move programatically across the screen, and when it hits a wall,
reposition it in the center. I've set up an NSTimer, and in the
timerFireMethod have this:
NSRect ballFrame = [ball frame];
ballFrame.origin.x+=ballDeltaX; // move the ball
ballFrame.origin.y+=ballDeltaY;
works just fine, the ball merrily moves across the NSView. However,
when I hit the wall, and do the following:
[myController victoryGoesTo:'R'];
[timer invalidate];
[self placeBallInCenter];
the placeBallInCenter method fails:
-(void)placeBallInCenter{
[ball setFrameOrigin:NSMakePoint(125,125)];
NSLog(@ball frame: %@,NSStringFromRect([ball frame]));
}
The ball's origin displays correctly in the console as (125,125), but
the ball is stuck on the right hand side of the screen, at around 400.
I'm using the same technique in placeBallInCenter as I did in my
timerFireMethod, so I am perplexed.
Thanks for any enlightenment,
Michael

[ball setFrameOrigin:NSMakePoint(125,125)];
NSLog(@ball frame: %@,NSStringFromRect([ball frame]));
}
The ball's origin displays correctly in the console as (125,125), but
the ball is stuck on the right hand side of the screen, at around 400.
I'm using the same technique in placeBallInCenter as I did in my
timerFireMethod, so I am perplexed.
Thanks for any enlightenment,
Michael

Re: Array Controller Add method question

I'm using an Array Controller's Add method wired to a button to

table contains many rows of data and the user clicks the Add button
the
table's lowest row activates. The user is forced to scroll down to

int row = [a indexOfObjectIdenticalTo:p];
[tableView editColumn:0 row:row withEvent:nil select:YES];
a = your array controller/arrary
p = object added
The OP asked for the item to be added at the top, so that doesn't
help...
You need to make sure you insert the new object at the right place in
the array controller's arranged objects.
One approach is to implement a new action method in your document/
application controller:
- (IBAction)newAtTop:sender {
id newObject = [arrayController newObject];
[arrayController insertObject:newObject atArrangedObjectIndex:0];
[tableView editColumn:0 row:0 withEvent:nil select:YES];
[newObject release];
}

Re: NSImageView gets stuck

That's a good idea, but I don't believe so: when I replaced my [ball setFrameOrigin:NSMakePoint(125,125)]; line with these: NSRect ballFrame = [ball frame]; ballFrame.origin.x=125; // move the ball ballFrame.origin.y=125; [ball setFrame:ballFrame]; I have the same outcome: the ball stays stuck.

Re: NSImageView gets stuck
Hi Michael, it's not clear from your code or your message, but could it be that your timer method calls setNeedsDisplay: YES on the appropriate view, but the placeBallInCenter method does not? I've recently made that very mistake and scratched my head for quite a while before I noticed the missing call. Hope this helps.

File Sharing Within App
Hey, Is there an easy way to embed a file-sharing server into a Cocoa application? Right now, I have a client-server setup that communicates via distributed objects (with Bonjour for discovery). I would like the client to be able to download files from the server, but I don't want to write my own file sharing protocol. Perhaps there is an ftp server I can embed into my server? My purpose in embedding the file sharing server into my application would be to save setup time. It seems the alternative would be instructions for enabling AFP, putting all of the support files into the right directory, then inputting the access information (path, username, password) into the server so the clients can access it. This is an in-house application, so that is all possible, but definitely not preferred. The way I envision my application working, the first time the server opens it would prompt for the directory with all of the supporting files. It would then vend this folder (read-only access) via FTP or a similar protocol. Simple and easy! Are there any libraries / frameworks you would recommend?
