This behavior is common to all status bar items, and is arguably a bug.

Re: Drop dowm status menubar item while hovering cursor over it
What Mr. Farmer was saying is this problem is a known bug with no workaround or quick fix. You will have to wait for Apple to fix this in a future system update. There is nothing you can do to your application to make this work properly. If you make a separate status item plugin, that will work properly because it is loaded and handled by the same process as all the system status items. But a status item from an application won't work the same.

How to Access NSArrayController Contents in NSCollectionView Views?
I am currently have trouble trying to understand how to access objects in an NSArrayController in conjunction with a NSCollectionView. I have a class entitled: VCMovieObjects, which contains information on a specific video clip. These objects are loaded into an NSArrayController, which is bound to a NSCollectionView. The NSCollectionView loads up my own subclassed NSViews (VCMovieContainer) into its contents for each object in the NSArrayController. I know I can bind various labels on my subclassed NSView to show the properties stored in my VCMovieObjects, but I want my VCMovieContainer to be able to access the appropriate VCMovieObject itself in the code, that way I can access all the data I need from it and use it appropriately when drawing the contents of the VCMovieContainer that correlates to that specific VCMovieObject. I am not sure about how to go about doing this in the correct way. I consider trying to bind an Object to the NSArrayController, and then creating an Outlet to that object from my custom NSView, but I don't know if it will maintain the correct reference to the right object that coressponds with the particular view. When I tried it, I just got a null when trying to access data. I want to avoid subclassing NSArrayController if possible. Any pointers would be appreciated.

SQLite -- same DB, different machines - different results
Hello. I've written the alfa of my first app on the Mac which works in an acceptable manner on my macbook. But when i run it on my iMac, it returns different results for the in seemingly the same conditions. The application is a dictionary. As the user types a word into the searchfield, he/she gets a completion suggestion (much like in Xcode for class or variable or method names or like in Safari for web- addresses). In my case it is the first word in the database with the prefix the user has already typed. So, for example, if a the user types te, the first suggestion (s)he gets is tea. But on the iMac, the user does not get that completion... Again, the application is completely the same. It is the release build. It has the same database. Now that I think about it, the versions if SQLite may be different, but that shouldn't really matter, for SQL syntax is pretty standard. And the tables in the database do have an autoincremental id (besides the 'rowid'). What could be the reasons for that? Thank you in advance, Timofey. By the way, if you are willing to try it, I think i could upload it somewhere... It is a russian-english-russian dictionary. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Get|SetControlProperty() equivalent
Hi, I'm pretty sure I know the answer to this question, but I'll ask it anyway :-)... Is there a Cocoa equivalent to Carbon's Get|SetControlProperty() family of functions? For those not familiar these functions let you associate user data with controls. I've never really used this for much, but it is very useful for storing a pointer to a C++ object representing the control in a UI framework, for example. It would be great to be able to do this for NSViews but I haven't been able to find any equivalent. Are there any ingenious ways that you might be aware of so I could bolt this on to NSView? I'm trying to avoid setting up a map from NSViews to UI framework objects, but I suspect it will be inevitable. Not really a big deal, but less hassle to be able to associate the data directly so that would be a preferable solution.

Stepping the event loop?
Hi, Although I'm ashamed to admit it, there are certain parts of our application that rely on stepping the event loop manually to maintain interactivity during intensive processing. It actually worked pretty well. Eventually I would hope that all such processing can be moved off onto secondary threads but unfortunately that isn't practical right now, so I need to reproduce this cringeworthy behaviour in Cocoa. One way which occurs to me is create a custom event loop in Cocoa but from the few examples I've seen of that it looks like it could be a bit more involved than with Carbon, or at the very least people are far more hesitant about doing it. Our app did have a custom Carbon event loop so it could do various things, but happily I've been able to avoid that so far with Cocoa. I have seen this as an example of the inner loop of a custom Cocoa event loop ( from http:// cocoawithlove.com/2009/01/demystifying-nsapplication-by.html ): [pool release]; pool = [[NSAutoreleasePool alloc] init]; NSEvent *event = [self nextEventMatchingMask:NSAnyEventMask untilDate:[NSDate distantFuture] inMode:NSDefaultRunLoopMode dequeue:YES]; [self sendEvent:event]; [self updateWindows]; which looks straightforward enough, but at this stage I don't have the experience with Cocoa to know whether this is really sufficient. Are there any other ways to step the event loop manually in Cocoa? I need to support 10.4 and up.

Hello, I am writing a Foundation tool - a command-line utility that uses Objective-C and the Foundation framework, and I'm trying to save preferences under the application domain..

Re: SQLite -- same DB, different machines - different results
I guess I would ask the same question I asked another recent poster: is there some reason you can't install the dev tools on the iMac and use them to debug the problem? It's *your* iMac, right? Not some customer's machine that you don't have access to? If installing the dev tools is not an option, you could also, as someone suggested, add NSLog statements to your program at key points. Either way, the objective is to figure out which line of code is behaving differently on the two machines. Find that line of code and tell us what it is. --Andy On Jun 10, 2009, at 7:36 PM, Тимофей Даньшин wrote: Hello.

Subclass NSView and use poseAsClass to replace the default implementation. You'll need to do the posing before running NSApplicationMain.

I really don't understand what the hell is wrong with it; Is this the same problem as your earlier post? It seems like maybe you're trying to do stuff with NSObjects before the runtime is initialised properly. Obviously it's not adding the extra ivar that's causing the problem, but some other problem that this exposes. What objects are you creating when? Are you doing anything in main()? Generally your app shouldn't start to do any processing until the app delegate gets the green light in the form of - applicationWillFinishLaunching: or similar. Try also enabling NSZombieEnabled, as it sounds like you may have a memory management problem (over-release most likely). --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

It's rare that an app crashes silently. Is anything printed to the
console? Do you have a crash log? If you run the app in the
debugger, what line of code does it crash on?
Also, are there any compiler warnings that you are ignoring?
These are the very first things you should look at when you're
debugging, and if you're still stumped, this is the kind of
information that would help us help you. When you post a question,
try to include relevant information.

Doc kind from extension
Anyone knows how to get the system doc kind from a given extension. Not from a file, or a file path for that matter, but just from an extension.

NSString becoming invalid
In an Xcode (3.1.2) Cocoa document app targeting 10.5, I read an NSString from an XML file and store it, eventually, in a C++ struct as NSString *fname; This works most of the time but, sporadically, I get a BAD_ACCESS crash with an indication that fname has become invalid. The only explanation I have found for this is that fname was not sufficiently retained and has been garbage-collected. Note: All my C++ files have a .mm extension and garbage collection is *required*. Thus, I have no retain/release calls at all. Is there something more I need to do or is there some other reason why this might be happening?

So I release more stuff than I should be? But wouldn't that lead to more obvious wrong behavior, as the app don't have the information it needs at some point ..? Who knows? We haven't seen the code. Over-release very often leads to weird behaviour because the place in memory where the object used to reside is now occupied by another object. Or not... sometimes the second release will provoke a crash but very often it won't, being handled as a legitimate message on the new object. How this manifests itself in your app will vary and is highly unpredictable. NSZombieEnabled makes the situation more predictable by reserving the released memory and trapping any further messages to it. The Debugger Debugger is attaching to process And then what?

Is there something more I need to do or is there some other reason why this might be happening? The collector does not watch all memory, but only the bits that it has been informed will hold object pointers. This includes the stack, global variables, and parts of the heap that were allocated from the collector's pool. Heap memory also needs a write barrier when assigning. Thus, you must allocate this struct using NSAllocateCollectable and pass the appropriate options to get scanned memory if you are going to store an ObjC object pointer in that struct. If you store a pointer to this struct in the heap, that memory must ALSO come from a collectable area and the pointer must be declared as __strong. As an alternative, you can CFRetain the NSString, which will remove it from being eligible for collection. You will have to balance this with a CFRelease when you're finished with it, of course. As another alternative, make this struct an ObjC object instead, and all the details will be handled for you.

pictureListController = [[PictureListController alloc] init];
[pictureListController showWindow:nil];
---
@implementation PictureListController

//self = [super init];
//[self setImagesArray:[NSArray array]];
[self adjustPictureArray];
NSLog(@[DEBUG] about to initWithWindowNibName:@PictureList);
[self initWithWindowNibName:@PictureList];
NSLog(@[DEBUG] AFTER initWithWindowNibName:@PictureList);
return self;
}
[...]
#define KEY_KEY @KEY
#define IMAGE_KEY @IMAGE
- (void)adjustPictureArray {
NSLog(@[DEBUG] adjustPictureArray -awakeFromNib);
NSMutableArray *mArray = [NSMutableArray arrayWithCapacity:10];
NSDictionary *pictDict = [DataModel picturesDict];
for (NSString *key in [pictDict allKeys])
{
NSImage *image = [DataModel pictureDictWithID:[key intValue]];
NSMutableDictionary *imageDict = [NSMutableDictionary

key, KEY_KEY,
image, IMAGE_KEY,

[mArray addObject:imageDict];
}
[self setImagesArray:[NSArray arrayWithArray:mArray]];

I can change things around to do them in a different order and get the

the same problem. If I break on the code and examine my array (the
referencedObject), it's an array of dictionaries, with keys KEY and
IMAGE, as expected, long before the view displays.
Am I missing some best-practices thing, here? Is there a special
ordering in which I need to do this stuff? I swear this worked a week
ago and I didn't change anything (other than to install the new SDK
sigh)

Growing UITextView in UITableView
I'm trying create a UITableView like the one Apple uses for composing an email in its mail app. As far as I know, it is a UITableView with UITextView for the mailmessage. There has been written a lot about this topic yet, but I haven't found the solution for my problem. I managed to only let the tableView scroll instead of the UITextView as well. But how can I let the textView (and the tableviewcell it's placed in) grow with the text? In other words: How can I change the height of the textview and the cell at the moment a new line appears? I tried a lot, but nothing helped so far. Thanks in advance! Arie Pieter ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Photoshop plugin with Cocoa UI problems
What doesn't make sense is that the plugin i worked on was modal (it was an export plugin). What I noticed in our window does is a call abortModal on the windowWIllClose notification. From what i can see, from the messages in your original post, it looks like you are still in the modal loop. Putting the notification there allows the window to handle when [window close] is called.

The main plugin is a Carbon bundle that locates the Cocoa bundle that actually contains the core plugin as suggested here: http://furbo.org/2008/07/08/plug-ins-the-cocoa-way/ The Cocoa bundle exports a plugin entry point as a C function. The Carbon bundle calls this from its own entry point using CFBundleCreate / CFBundleGetFunctionPointerForName, but it never releases the Cocoa bundle since apparently Cocoa bundles should not be unloaded. The whole idea behind this, as far as I can see, is that Photoshop unloads the Carbon bundle, but does not unload the core Cocoa bundle. Next, the Cocoa bundle calls NSApplicationLoad, displays an empty window using [NSApp runModalForWindow], then closes the window and returns. At this point, I get the aforementioned crash.

Re: App does not start on a different machine
The debugging suggestions made so far in this thread are fine. But really, the only debugging tool needed here is your mind. Developing that tool is the quickest route to fixing bugs like this. 11.06.09 04:24:30 test[767] *** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0) 11.06.09 04:24:30 test[767] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)' This is a huge hint as to what the trouble is.

Right now, you're not really thinking about it (no offense intended), you're just trying stuff, hoping something fixes it, and when that doesn't work, posting requests for help without including enough detail for anyone to help you. The trouble is not the bug in your code (everyone creates bugs, and this one is easy) it's the bug in your thinking about the bug. So how can I find the array call that leads to this? Cmd-Shift-F, type objectAtIndex, make sure the search options popup is set to In Project, hit Return. In the resulting list, look at each found occurrence of objectAtIndex. Option-click on objectAtIndex to bring up its docs. Re-read them. Re-read your code. See see where you might be using objectAtIndex incorrectly. If you don't see the problem with your usage of objectAtIndex, post the code here so others can see it. You've said your app is pretty simple. Any occurrences of objectAtIndex: were likely put there by you. Look at each one and examine how you use it. Re-read the documentation for objectAtIndex and consider if anything you do might be out of accord with the docs you read. If by chance you don't find any occurrences of objectAtIndex, look at all your other usage of NSArray/CFArray and think about what might happen if any of them happened to invoke objectAtIndex with the values you pass. Could your values trigger any problems? Failing that, look at every line you've written. Your program is small and simple.

Re: Passing References During Initialization / Nib Loading
On Jun 11, 2009, at 11:52, Brad Gibbs wrote: In short, I need a more reliable way to pass references to my MainWindowController into objects that are awaking from nib files. Trying to set the mMainWindowController variable to self.view.window.windowController in the awakeFromNib method seems to be happening before the MainWindowController is instantiated, so, it sets the variable to NULL. I need to call a method in the MainWindowController to switch views / viewControllers, passing in the new viewController as an argument. I can set the mainWindowController variable in the method that actually invokes the view switch, but that seems clunky. It seems like there should be a method I can call to set the variable once the view controller has awoken and the app has fully loaded. initWithCoder and awakeFromNib happen too soon and applicationDidFinishLaunching only gets sent to the app delegate. You haven't really described how things are arranged, in a way that we can understand. You have a window controller, plus a view controller for each set of controls/objects in its own nib file? How do the view controllers get created? As Kyle said, to avoid having to manually resolve the timing of when instance variable can be set in objects loaded from nib files, you should use outlets instead of instance variable in objects coming from nib files. I think your mistake is trying to connect directly to the window controller across multiple nibs. Probably the correct solution involves putting a 'main window controller' property in each view controller, and putting a mViewController reference in the nib objects. Then you'd refer to the main window controller as mViewController.mainWindowController (or whatever). If your view controllers are being created programmatically, you'd pass the window controller as a parameter when creating them. If, for some reason, you have the view controllers in your main window nib file, then you'd use outlets to connect them to the main window controller. But that's all guesswork, without further information. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: self Changes on Open Panel [solved]
I want to thank Fritz, Greg, Quincy and Uli for their help solving this problem. I don't think there is any general solution to this problem, but I wanted to make two remarks that might help others who run into something similar. (i) It turned out that i did have two different MyDocument objects. The second was being instantiated by MainMenu.xib. I actually checked the other .xib files looking for a MyDocument object, and turned up nothing; but I didn't think to look at MainMenu.xib. (ii) I tracked down the problem by creating a breakpoint at - [MyDocument init]. This led me to search every .xib looking for an instantiated MyDocument. I am a bit puzzled about one thing: I did put an NSLog at the beginning of the -init method, with a view to determining when the second MyDocument object was being instantiated. But, the NSLog fired only once. As many have pointed out, the object could be created with an -initWithCoder, so the NSLog would be skipped (presumably this is what happened when the .xib instantiated the object). But if this reasoning is correct, why, then, would -[MyDocument init] as a breakpoint stop the code twice? I mean, it shouldn't stop the code when -initWithcoder is called, right? Anyway, thanks again for all your help. On 10-Jun-09, at 11:48 AM, Uli Kusterer wrote: On 09.06.2009, at 17:48, Greg Guerin wrote: How do you know -init is only run once?

Re: Passing References During Initialization / Nib Loading
Hi, Thanks for the response. I was trying to make the post short, hoping to up my chances of getting someone to read through the entire thing and take the time to respond. I guess I just made it confusing. So, now for the long(er) version. I have a single window application. It's a Core Data, non-document- based app. At launch, the appDelegate loads the mainWindowController, which controls the app's only window. In the main window, there are three views -- a status bar across the top, a menu view down the left side (Jonathan Dann's Animating Outline View embedded in a view, rather than a window) and a content view, which takes up the rest of the main window. The mainWindowController loads initial views for these containers. In each section of the menu (the outline view) is a table view with a single column, which lists the titles for the view controllers. For the most part, a single view controller controls a single view, which is displayed in the content view portion of the main window. These view controllers are subclasses of a custom subclass of NSViewController with variables for the main managedObjectContext and the mainWindowController. The method call to remove the view currently in the content view portion of the main window and replace it with the new view controller's view is in the main window controller. I had been manually instantiating the view controllers and passing references to the main window controller and the main managed object context with a custom init method ( initWithMoc: andWindowController:) and using these arguments to set variables in the view controllers. Today, I decided to try to refactor and clean up some code by instantiating the view controllers in nibs, but I ran into the problem I'm trying to describe. Yes, I'm using 10.6, but I think the problem can be abstracted enough to be discussed without breaking the NDA.

Trying to set the mMainWindowController variable to self.view.window.windowController in the awakeFromNib method seems to be happening before the MainWindowController is instantiated, so, it sets the variable to NULL. I need to call a method in the MainWindowController to switch views / viewControllers, passing in the new viewController as an argument. I can set the mainWindowController variable in the method that actually invokes the view switch, but that seems clunky. It seems like there should be a method I can call to set the variable once the view controller has awoken and the app has fully loaded. initWithCoder and awakeFromNib happen too soon and applicationDidFinishLaunching only gets sent to the app delegate. You haven't really described how things are arranged, in a way that we can understand. You have a window controller, plus a view controller for each set of controls/objects in its own nib file? How do the view controllers get created? As Kyle said, to avoid having to manually resolve the timing of when instance variable can be set in objects loaded from nib files, you should use outlets instead of instance variable in objects coming from nib files. I think your mistake is trying to connect directly to the window controller across multiple nibs. Probably the correct solution involves putting a 'main window controller' property in each view controller, and putting a mViewController reference in the nib objects. Then you'd refer to the main window controller as mViewController.mainWindowController (or whatever). If your view controllers are being created programmatically, you'd pass the window controller as a parameter when creating them. If, for some reason, you have the view controllers in your main window nib file, then you'd use outlets to connect them to the main window controller. But that's all guesswork, without further information. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: UTI not identified correctly for some users.
As a followup to this, it appears that the users having problems do have a different app set for this file type, so it's not recognizing my UTI name for NSOpenPanel's setRequiredType: and NSWorkspace's typeOfFile:... Is there a way around this besides specifying the file extension explicitly? Should this be reported to Apple?

Are there any ingenious ways that you might be aware of so I could bolt this on to NSView? I have yet to find a good solution to this. It would be fantastic if NSView had an NSDictionary field and Interface Builder let you set values in the dictionary. Given the pain of writing Interface Builder plugins, this would be a much easier solution to a bunch of problems where you want a custom view to have some configuration. The only vaguely approximate thing is the tag field in NSControl, which you can subvert for some purposes, but it is very limited. I'm trying to avoid setting up a map from NSViews to UI framework objects, but I suspect it will be inevitable. Not really a big deal, but less hassle to be able to associate the data directly so that would be a preferable solution. The only alternative I could see would be to create a global NSDictionary mapping NSView* to UI framework objects, use message swizzling on NSView to swap out its init and dealloc methods, and add a category on NSView to access the UI framework objects via the global dictionary. Slightly ugly to write and then trivial to use. You probably don't need to swizzle the init methods, just create the global dictionary entry on demand as necessary, but you do need to swizzle the dealloc method to know when to get rid of the entry.

Questions on using using modal sheets with Core Data
Hi all, have a Core Data document based application which uses modal
sheets as a way for the user to edit the document's data. What is the
best way to give the sheet the ability to operate on a copy of the
data with the parents sheet's undo context? And how best to merge
these changes with the main document context.
I've thought of having a unique MOC for each sheet, and then posting a
custom notification that would in turn cause each MOC to perform
something like:
for (id object in [managedObjectContext registeredObjects]) {
[managedObjectContext refreshObject:object
mergeChanges:YES];
}
Does this way make any sense? Is there a better way to do this that
I'm missing?
Thanks for any pointers!

There's nothing wrong with that approach, though it's not perhaps what might be understood as a singleton.

Singleton usually suggests code within the singleton's class to actively prevent other instances being created by unruly client code. That's not necessary here. The only drawback with making your main window controller global, and it's perhaps a fairly theoretical concern, is that one of the benefits of encapsulating parts of your interface (such as multiple view nib files) is the elimination of global relationships that hamstring your code. Localizing the relationships makes the pieces easier to put together safely.

NSFontPanelDocumentColorEffectModeMask);
}
I can't seem to show the color buttons explicitly, and removing, for
instance, NSFontPanelStrikethroughEffectModeMask or
NSFontPanelUnderlineEffectModeMask simply doesn't work right (usually,
an underline popup is shown in the panel, but the text color effect
button is hidden).
Is NSFontPanel simply buggy even in 10.5, or am I missing something
here?
This works as designed:
return NSFontPanelAllModesMask- NSFontPanelShadowEffectModeMask;
but of course that's not really what I want to do.
PS.: please cc me in replies.

Re: Questions on using using modal sheets with Core Data
This is explained in the NSPersistentDocument tutorial in the docs.
On Jun 11, 2009, at 10:03 PM, Kevin Ross wrote:
Hi all, have a Core Data document based application which uses modal
sheets as a way for the user to edit the document's data. What is
the best way to give the sheet the ability to operate on a copy of
the data with the parents sheet's undo context? And how best to
merge these changes with the main document context.
I've thought of having a unique MOC for each sheet, and then posting
a custom notification that would in turn cause each MOC to perform
something like:
for (id object in [managedObjectContext registeredObjects]) {
[managedObjectContext refreshObject:object
mergeChanges:YES];
}
Does this way make any sense? Is there a better way to do this that
I'm missing?
Thanks for any pointers!
Kevin

Re: UINavigationController for desktop Cocoa?
Seems a little weird on the desktop. The whole point of the navigationController is to provide a solution to the problem that a small phone screen isn't good at showing more than one task at a time. We don't really have that problem on the desktop.what exactly do you want to do? Luke On Jun 11, 2009, at 6:38 PM, Houdah - ML Pierre Bernard wrote: Hi!

FWIW, your return type is wrong -- it should be NSUInteger, though
that wouldn't make a difference unless your app was 64-bit.
