[NSWindow title] isn't the title

[Quincey Morris]

This is more of a curiosity than anything else, but ...

I have a (non-document) window whose title is set with 
'setTitleWithRepresentedFilename:'. The title actually shown in the title bar 
is the last path component of the file path, as expected.

I have an associated window whose title I'd like to be of the form " — Info".

However when I try to build this from the base window's displayed title, I 
actually get a string with the file name and the path to the file, so I end up 
with  something of the form " —  — 
Info", which isn't really what I want.

The -[NSWindow title] documents this behavior ("If the title has been set using 
setTitleWithRepresentedFilename:, this method returns the file’s path."), but 
that leaves no way to get the actual displayed title.

Does anyone know of a way to get the actual displayed title?

Note:

1. As a work around, I am building the associated window title from the base 
window's 'miniwindowTitle', but there's no guarantee I can see that ensures (in 
the future) this will be what's displayed in the actual title bar of the base 
window.

2. In the past, I've used [NSWindowController 
windowTitleForDocumentDisplayName:] for this purpose, but that doesn't work in 
this case, since there's no actual document.

Re: Automator Actions and CFBundleExecutable key

[Mark Munz]

I've run into this as well -- particularly with Automator Actions. I
decided to finally track down the issue.

The root cause appears to be that the RunScript Phase is being called
too early in the build process. So when amlint checks for an
executable, it hasn't been built yet.

If you look at your detailed log, you'll likely see that the RunScript
occurs right after resources are copies, but before the code is
compiled.

I put ${BUILT_PRODUCTS_DIR}/${FULL_PRODUCT_NAME} in the input files
list. Not sure if that is the proper way or not to force the Run
Script to wait for the actual product to be built, but it appears to
do the job.

Hope that helps.

Re: Crash on NSKVOPendingNotificationRelease (KVO, bindings issue?)

The likely answer (see below for the reasons) is that this is probably not a 
good approach. Your application needs a specific behavior of change 
propagation, cycle elimination -- as well as other possible constraints -- that 
KVO has no API contract to provide. I'd recommend you spend the effort on 
designing your own object graph and related behavior.

I *believe* that KVO contains at least one (major? inherent?) bug that causes 
crashes like this with certain patterns of observations. Whenever I run into 
such crashes, I've never been able to work out whether it is in fact a bug, or 
if I did something wrong, nor to recreate the crash in a more controlled 
context that could be used as the basis of a bug report.

So you might have run into a bug. Or you might have set up an observation 
pattern that KVO doesn't really support (either at the level of observers or 
the level of notifications).

KVO has two important defects from the developer's point of view: it's a black 
box system, so trying to understand what it's doing at any given moment is pure 
guesswork; and it's an implementation-defined system, so that beyond its 
general responsibilities, what is does is what it's "supposed to" do, and 
there's no independent standard of whether it's right or wrong.

Plus, KVO probably doesn't scale well as the number of observations increases. 
If your object graph is going to get large, performance may well become a 
consideration.

For all those reasons, I wouldn't suggest using it for an application like 
this, where *propagation* of the notifications across multiple objects is the 
key functional issue.

FWIW.

If you really need to "cache" the A value, then you have to use 
observeValueForKeyPath:ofObject:change:context:. Using 
keyPathsForValuesAffectingA only makes sense if you're going to produce the A 
value on demand.

Incidentally, this example points another defect of using KVO for your 
application. You want A to change when B or C changes, and it will -- 
literally, meaning twice. Once for the B change, and once for the C change. 
That means that A may temporarily have an invalid value, and that might itself 
be propagated via notifications before its final value is calculated. KVO 
guarantees no order for the notifications, and although in a few cases it might 
optimize some repeated notifications away you don't have a lot of control over 
the quantity of notifications that get sent.

Add a formatter to the cell and set the 'NaN symbol' to 0. You can do this in

The override you're looking for is actually -menuForEvent:, not 
-rightMouseDown: or -mouseDown:. Control-clicking is not the same as a right 
click.

Crash on NSKVOPendingNotificationRelease (KVO, bindings issue?)

[Glen Low]

I'm using KVO as a generalized recalculation engine, somewhat akin to how a 
spreadsheet recalcuates values based on what's changed. It's mostly successful 
once you eliminate cycles, but there is a persistent problem.

On each relevant object, I have a 
observeValueForKeyPath:ofObject:change:context: method which then triggers 
willChangeValueForKey:  / didChangeValueForKey: for dependent properties. I've 
noticed that when observeValueForKeyPath:ofObject:change:context gets called 
more than once in a row for an object, one of the other observed objects dies 
in didChangeValueForKey: -- here's the stack trace

Program received signal:  “EXC_BAD_ACCESS”.

#0  0x7fff84d31ae1 in NSKVOPendingNotificationRelease
#1  0x7fff88aa0bd3 in __CFArrayReleaseValues
#2  0x7fff88a815f8 in _CFArrayReplaceValues
#3  0x7fff84d31e35 in NSKeyValuePopPendingNotificationPerThread
#4  0x7fff84d31dca in NSKeyValueDidChange
#5  0x7fff84d1574f in -[NSObject(NSKeyValueObserverNotification)

#6  0x1000181c8 in -[CMEdge didChangeValueOnceForKey:] at CMEdge.m:133
#7  0x100019f51 in -[CMNode 
observeValueForKeyPath:ofObject:change:context:] at CMNode.m:222

The only workaround is to perform the didChangeValueForKey: in the next event 
cycle i.e. by using performSelectorOnMainThread:withObject:waitUntilDone:

Not really ideal especially since I'm worried I'm just covering up the root of 
the problem, whatever it is.

Any ideas on the cause?

Side question: I can of course use keyPathsForValuesAffectingValueForKey: and 
friends to declare the dependencies instead of using a procedure to react to 
them, but I need to execute code as well e.g. update the observed value. For 
example, say A = B/C. When either B or C changes, you want A to change too. I 
can use keyPathsForValuesAffectingA to declare it depends on B or C, but I need 
to update the cached A value whenever B or C changes -- how would I do that 
without using observeValueForKeyPath:ofObject:change:context:?

For something as real-time as video or audio, you can't provide a

a timer and periodically check the current time of the movie, and
adjust your playhead accordingly.

Re: Determining preferred localizations

[Gary L. Wade]

I see what you're getting.  The issue is that the keys you're getting back
by utilizing kDisplayProductName from IOKit only have paired
language/territory (e.g., "en_US") while the AppleLanguages array in your
setups have non-paired ones for most languages (e.g., "en").  If you were to
turn on paired language/territories in the System Preferences (e.g., "U.S.
English") in the desired order, you could get what you're wanting.
Basically, you're asking for something highly specific, but the
configurations only provide more general, so fallbacks go a lot farther than
what you want.

The only way I've been able to bypass this without adding settings to the
System Preferences is to split the pairs and introduce language-only objects
after each pair provided such strings are not already present.  So, you
would rework your array on the MacBook Core 2 Duo 10.6.3 from:

"nl_NL"
"da_DK"
"pl_PL"
"en_US"
"nb_NO"
"fr_FR"
"pt_BR"
"pt_PT"
"zh_CN"
"es_ES"
"ja_JP"
"ru_RU"
"sv_SE"
"zh_TW"
"de_DE"
"fi_FI"
"it_IT"
"ko_KR"

to:

"nl_NL"
"nl"
"da_DK"
"da"
"pl_PL"
"pl"
"en_US"
"en"
"nb_NO"
"nb"
"fr_FR"
"fr"
"pt_BR"
"pt_PT"
"pt"
"zh_CN"
"es_ES"
"es"
"ja_JP"
"ja"
"ru_RU"
"ru"
"sv_SE"
"sv"
"zh_TW"
"de_DE"
"de"
"fi_FI"
"fi"
"it_IT"
"it"
"ko_KR"
"ko"

Not sure how Chinese would work, though, since there's really not a
practical locale of "zh".  Also, you may have issues with the "Hans" vs.
"CN" convention.  Look at the locale APIs to help with splitting and
normalizing these values.

I don't think many people would be surprised that any given "Top 10" list
must contain, by definition, 10 or fewer such applications "that use
RegexKitLite that don't acknowledge their use".


However, it does not necessarily follow that there can only be 10 or fewer
'"Top 10" applications that use RegexKitLite that don't acknowledge their
use'.  Just because all beaucoup fish are fish does not mean that all fish
are beaucoup fish.  Your conclusion would true if, and only if, there was a
single "Top 10" list.  It is assumed, without proving, that there is more
than one "Top 10" list.


There are an awful lot of "Top 10" applications that use RegexKitLite that
don't acknowledge their use.  QED.

I think one of us has misunderstood, because I'm not sure how this response 
actually addresses my question. I'll restate and try to be more clear.

I'm trying to present to the user a list of the attached displays. For any 
given display device, the "name" I get from IOKit is not a string but a 
dictionary mapping locale identifiers to localized versions of the device name. 
My goal is to determine which of the dictionary entries to use.

I thought NSBundle's preferredLocalizationsFromArray: and 
CFBundleCopyPreferredLocalizationsFromArray() would take an array made up of 
those dictionary keys and give me back a subset of the list, prioritized based 
on such things as the user's localization settings and the available 
localizations within the app. What I'm getting is an array containing a single 
entry which doesn't match the app's development region, doesn't match any set 
of localization resources in the app and is at an unpredictable (although 
consistent per machine) offset in the user's preferred language list.

System Profiler and the Displays pref pane both show the appropriate value. I'm 
sure I'm doing something wrong but I don't know what.

Short form: How do I get from an NSScreen or a CGDirectDisplayID to the most 
appropriate human-readable name for the display?

Except that there can be many Top Ten lists (Mac Apps, iPad Apps,  
iPhone Apps, Productivity Apps) etc, and then different sites/people  
put different things on their lists.   You could pretty quickly get a  
list of unique programs much larger than 10 ;)

There was a compiler bug wherein deprecation warnings on class methods did not 
work. It should be fixed in a future developer tools release, if it isn't fixed 
already.

I just downloaded and built the sample without issue, the ReadMe describes what 
you might need to do to include libXML in your own project, not modifications 
necessary to the sample (sample code is designed to be self contained and built 
without modification as a general case).

Re: Determining preferred localizations

[Gary L. Wade]

The list you are getting is a set of preferred localizations, so when trying
to get a resource from the first one, if not available, will go on to the
next one and so forth.

You should utilize the localization-aware methods to handle getting
resources rather than trying to manage this yourself.  There's really only
two reasons I've encountered a need for this kind of granularity, the first
where you're forced to use a set of legacy resources that you're unable to
move into the right places, and the second a localization utility.

playing QuickTime movies on iPhone/iPad?

[Steve Christensen]

I have a need to be able to play a QuickTime movie containing subtitle  
tracks, and to be able to turn specific tracks on or off. In looking  
through the iPhone/iPad docs, it looks like the movie player classes  
are pretty much restricted to simple playback functions. Have I missed  
something?

Re: Custom progress bar for QTMovie??

Chase,

The method I use for doing this relies on QuickTime, not QTKit.  Even so, I 
think it is most effective.  I implement a movieController action callback 
filter.  This method is demonstrated in the "Adding New Capabilities to the 
QTKitPlayer Application" section of this document:

NaN Problem Adding Numbers from NSTableView

[Philip Juel Borges]

Hi,

I've googled this issue to no avail until now. In my application I  
have a tableview with 6 columns to enter numbers for statistic  
purposes. That works fine. Yet, I've run into a problem adding the  
numbers together. Under each column below the tableview I have placed  
an NSLabel to show the total amount. I bind that label under Value in  
the bindings panel like so:


Bind To: myArrayController
Controller Key: arrangedObjects
Model Key Path: properti...@sum.hours

But some times I need to leave a tableview cell blank and then it  
writes NaN in the label. If I type in 0 (zero) it adds up the numbers  
nicely. But I'd rather just leave the selection empty rather than  
typing in a zero.


Any ideas how to solve the NaN issue?

Determining preferred localizations

[Gregory Weston]

I'm trying to display a localized list of attached displays, and getting 
unexpected results in Carbon and Cocoa when attempting to determine the best 
localization. I did all the obvious-to-me Google searches without finding much

real resolution. Sample code and results follow. Hoping someone can point me in 
the right direction.

FWIW, I've tried both "en" and "English" for both the Info.plist development 
region and the localized resources folder in the app.

Thanks for any help.

I've seen the same problem with tool-type targets, though only in build configs 
with the setting Build Active Architecture Only unchecked (e.g., the Release 
config, in a new Foundation tool project). I first noticed it with Sparkle on 
3.2.2 - building the relaunch tool target shows these warnings.

It looks like it's a bug in 3.2.2. I filed it (rdar://7872548), in case anyone 
else wants to jump on the bandwagon.

appscript project gives warning with XCODE 3.2.2

[John Love]

Everything worked just dandy for SourceForge's "appscript" with XCODE 3.2.1.  
But, with updating to 3.2.2, it is giving me some grief:

For one project, it's giving a warning:

ld: warning: directory '/Users/johnlove/Documents/XCode/Calculate 
Medical/../../../appscript/Appscript Framework Project/build/Debug' following 
-F not found

Being a warning, app still runs and runs impeccably.

I thought that maybe the appscript framework needed to be re-built with XCODE 
3.2.2 .. but that attempt generates an error:

There is no SDK with the name or path '/Developer/SDKs/MacOSX10.4u.sdk'.

I can hardly remember Tiger sdk's being on my hard drive.

Building with 3.2.1 gives no error.

need help getting Apple sample code to compile

[WT]

Hello all,

I'm trying to compile the XML Performance sample code for the iPhone, but I 
have so far been unsuccessful. I followed the instructions on the readme file, 
namely, to set the HEADER_SEARCH_PATHS build setting to 
$SDKROOT/usr/include/libxml2. I also tried both recursive and non-recursive (I 
think it should be recursive, since the directory in question contains another 
directory, libxml, which then contains the header files, even though the readme 
instructions say nothing about the recursive option). I've also verified that 
the library is in fact included in the project.

Yet, I keep getting errors such as

.../XMLPerformance/XMLPerformance/Classes/LibXMLParser.h:49:0 Libxml/tree.h: No 
such file or directory in 
.../XMLPerformance/XMLPerformance/Classes/LibXMLParser.h

I searched the archives for prior messages about this sample code but nothing 
came up.

What am I missing?

Thanks in advance.

Increase area for autoscrolling in NSScrollview

[Nikhil Khandelwal]

Hi,

In my application I have a NSScrollView which has NSView s in it. When I drag n 
drop the views inside the scrollview  autoscrolling in scroll view doesn't 
start from half of scroll point. It starts below from expected. Scrolling 
should start from the black line while in my application it starts from around 
red line which results in slow scrolling. Is there any way to increase the area 
for auto scrolling. I have tried some stuff from NSScroller but doesn't work.

[cid:image002.png@01CAE15A.F0B80B20]
Please let me know if someone faced this situation before.

Thanks,
Nikhil
