Re: Custom background in NSTableHeaderView

[Kiran Kumar S]

Hi,

	CellAttributes are used by button and button cell for displaying  
image and text accordingly, but tableHeaderCell doesn't uses these  
attributes for displaying image and  text.. Customize the  
NSTableHeaderCell and draw the image and text in drawWithFrame method.




Thanks
SKiranKumar

It doesn't. You'll have to parse the packets manually. Good luck.

Re: Vector images on Cocoa

[Gideon King]

WebKit has experimental SVG support 
(http://webkit.org/projects/svg/index.html), but I haven't tried it. 

I have been successfully using PDF vector images, which are pretty much the 
recommended standard format. 

We have also used EPS images, but found that occasionally people have crasher 
bugs with them, and we have not found any workaround. It happens for something 
like 1 person per 5,000 of our users, so it's pretty rare, but we have never 
been able to solve the issue, except by disabling the loading of EPS images for 
those people.

HTH.

Help needed in Writing network usage monitor application

[Aashishk Tiwari]

Hi All,

We are developing a network usage monitor cocoa application that should be
able to log what urls user is visiting, what streaming media being played,
what url is open in which browsers etc.
We need to get notified when any new url is visited or etc.

What APIs/library/Technology we should use that notifies us about network
usages and also provides us with the data being transmitted.

I have look in libpcap that pretty much gives the packets but i dont know
how much it helps in notification kind of things.

is there a Mac counter part of something like TDI (Transport Data
inferface) available in Win Vista?

Please guide me on this.

Thanks,
Aashish

what's wrong with it?

firstResponder KVO snow leopard crash; bug?

[Aaron Clarke]

We have an application that runs fine on leopard (10.5) but occasionally
crashes on snow leopard (10.6) when closing an NSWindow.  Here is the
backtrace for the crash:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x
0x976e691b in objc_msgSend ()
(gdb) bt
#0  0x976e691b in objc_msgSend ()
#1  0x197142d0 in ?? ()
#2  0x9031e88e in NSKeyValuePushPendingNotificationPerThread ()

willChangeValueForKey:] ()
#5  0x90327cfe in _NSSetObjectValueAndNotify ()
#6  0x92745fb8 in -[NSWindow makeFirstResponder:] ()
...

Even if it doesn't crash, closing the NSWindow always results in the
following error message.

An instance 0x11b75230 of class MyWindow was deallocated while key value
observers were still registered with it. Observation info was leaked, and
may even become mistakenly attached to some other object. Set a breakpoint
on NSKVODeallocateBreak to stop here in the debugger. Here's the current
observation info:
 (
 Context: 0x0,
Property: 0x4453e60>
 Context: 0x0,
Property: 0x4453e60>
)

I looked at what the observer object's class is, and it's a subclass of
NSCollectionView.  We do not explicitly setup a KVO relationship for
firstResponder.  I also noticed that the "Application Kit Release Notes for
Snow Leopard" mention that firstResponder is KVO-compliant, which makes me
believe this is something new in Snow Leopard.  All this information makes
me believe this is potentially a bug in Application Kit for 10.6.  Maybe we
setup an NSCollectionView incorrectly or I'm misinterpreting this
information?

Sorry, I meant to reply to the list instead of directly to you. I think you 
will find that you still want the text container width to be something like 
FLT_MAX. You don't need to make the text container the same width as the 
longest line of text. 


> Perhaps I'm misunderstanding, but this seems to be exactly how Xcode's
> text editor window works.

You mean when wrapping is turned off? You get that behavior for free. Try this:

1. Create a new project in XCode.
2. In the app delegate header, set up an IBOutlet to a NSTextView.
3. In interface Builder, add a NSTextView to the window and connect it to the 
IBOutlet.
4. Add this to the app delegate .m :

- (void)awakeFromNib {
[myTextView setHorizontallyResizable:YES];
NSSize tcSize = [[myTextView textContainer] containerSize];
tcSize.width = FLT_MAX;
[[myTextView textContainer] setContainerSize:tcSize];
[[myTextView textContainer] setWidthTracksTextView:NO];
}

Run the app. As you add text to the text view, you will see that the horizontal 
scroller adjusts as needed to accommodate the longest line. You don't have to 
do anything more.

From the docs: "Whether it tracks the size of its NSTextView or not, an 
NSTextContainer doesn’t grow or shrink as text is added or deleted; instead, 
the NSLayoutManager resizes the NSTextView based on the portion of the 
NSTextContainer actually filled with text."

Core Data derived property not recognized after save & reopen

[David Catmull]

I have an entity with a "date" property, and derived properties "year" and 
"month" (by having year/month methods in my NSManagedObject subclass). In a 
couple of different places, I fetch the entries from a particular year or 
month- the fetch requests's predicate says "year == 2009". 

This works fine except in a document that has been saved and reopened: the 
first time I make a change to an object, and then try to fetch a list of 
objects by year, an exception is thrown saying "keypath year not found". What 
confuses me is that between reopening the document, and making a change, I can 
make (as far as I can tell) the same request to filter by year (or month) 
without problems. It doesn't matter which property I change - date or anything 
else.

So I have two questions:
1. Why would this happen?
2. What's a good, simple way to write a unit test that simulates closing an 
reopening a Core Data document? I want to avoid actual file operations for the 
sake of simplicity, but NSPersistentDocument does not implement the 
dataOfType:error: method.

Sorry about the non-quite-Cocoa post. Newbie to OD here.

I wonder if we can continue this off-list.

I do know that OD has some notion of "directory domain", are not users

Set the height of your browser view to whatever you'd like that will contain a 
single row of your image cells. Then in your controller's -awakeFromNib use 
[imageBrowser setContentResizingMask:NSViewWidthSizable] to tell it you only 
want it to expand horizontally. Apparently the default is NSViewHeightSizable 
and I see no way to override that via IB.

The normal autosizing springs/struts in IB don't seem to affect the 
contentResizingMask at all for an IKImageBrowserView.

Hi Ross,

Fundamentally, I want to:

1. Display lines of text that don't wrap in my NSTextView.
2. Display a horizontal scrollbar.
3. Make sure that the width of the NSTextView is appropriately wide
for that line of text so that:
 3.1 The user can scroll the width of the longest line of text and no more.
 3.2 The scrollbar thumb is representative of that width.

The samples I found online to enable horizontal scrolling set the
width of NSTextContainer and NSTextView to the FLT_MAX, which is not
what I want to do as that invalidates my 3rd requirement (above).

I did try using lineFragmentX calls to try and get the width of the
line of text (but failed as the lines of text were wrapped), but I had
not used the call that you mentioned. I will try it out.

Perhaps I'm misunderstanding, but this seems to be exactly how Xcode's

Thanks for you suggestions, I'll let the list know how it works for me.

True, but keep in mind the amount of effort that Apple would need to do if they 
provided the custom control, etc:

* Must work with localized content
* Must work with accessibility
* For particular controls, probably need to have multiple sizes (large, small, 
mini)
* Probably will need to expose custom bindings
* Should work in resolution independence.
* Probably some other things I'm missing.

Definitely file an enhancement request though.  I'm sure Apple will strongly 
look into providing something if several developers end up asking for the same 
type of controls.

#0  0x92cc5fb8 in -[_NSZombie retain] ()
#1  0x92c2f1cc in -[NSInvocation retainArguments] ()
#2  0x93c5bc70 in _NSSendCommitEditingSelector ()
#3  0x93c7f1ec in -[NSController 
_controllerEditor:didCommit:contextInfo:] ()

#4  0x90a461f4 in objc_msgSendv ()
#5  0x92bf3fcc in -[NSInvocation invoke] ()
#6  0x92bf457c in -[NSInvocation invokeWithTarget:] ()
#7  0x92c02f38 in __NSFireDelayedPerform ()
#8  0x907f2384 in __CFRunLoopDoTimer ()

Items #2 and #3 make me think this might have something to do with the 
NSEditor protocol, but I don't understand how.  As far as I can tell, I 
don't have any objects that conform to that protocol... no NSDocument, 
no NSObjectController, etc.


OK, I was wrong about this, I do use NSUserDefaultsController, which is 
a subclass of NSController.  Apparently, when my OK button handler calls 
[mUserDefController save: self], that calls -[NSObject 
performSelector:withObject:afterDelay:inModes:], resulting in the zombie 
call.  I still don't understand why the user defaults controller would 
want to retain the window controller.

Thanks. 

Duplicate filed: rdar://7401294

Hopefully they will provide support for it again soon or, perhaps, some better 
alternative.

It's still the case.  10.6 added many API for things that previously
needed Carbon, but not this thing. :(  Perhaps it has fallen out of

[Q] Expanded tooltips in Cocoa?

[Eric Gorr]

In carbon, you could define both default and expanded tooltips for views.

I found this old thread:

http://lists.apple.com/archives/cocoa-dev/2003/Aug/msg00591.html

which indicated that expanded tooltips were not supported in Cocoa. 

In my hunting through the guides, I believe this is still the case. Or, have I 
missed something?

p.s. if you have gone to the extra effort of supporting expanded tooltips in 
Cocoa, how did you do it?___

addObserver:forKeyPath:options:context: memory management in GC

[Sean McBride]

Hi all,

The docs for addObserver:forKeyPath:options:context: say "Neither the
receiver, nor anObserver, are retained.".  They don't comment on the
garbage collected case specifically.  Does any know for sure?

Does calling this method add a strong reference between the receiver and
'anObserver'?  (I'm assuming not.)

Thanks,

For 10.6 and later, you ought to use IKScannerDeviceView, which apparently has 
no documentation at the time except for a few small mentions on ADC, such as  
,
 and the comments in the header file. It really isn't that difficult to figure 
out on your own, actually.

For 10.5 and earlier, use ICAImportImage(). Don't call this method in Snow 
Leopard! Not only does it not work, but it ends up crashing at some point if 
you don't have GC turned on. Yes, I filed a bug.

Re: CALayer Transitions

[Gordon Apple]

Here's the current status.  I seem to have everything working, partly
due to you guys.  Thanks.  However, now having analyzed this thing to death,
I'm filing a bug report.

First a summary of the (extended) problem.  The view is layer hosted.
Its layer has a sublayer called "content", which has sublayers, one of which
is A, which is to be transitioned to B.  This is akin to a
PowerPoint/Keynote slide transition.  Layers A and B also have sublayers,
A1, A2, etc., which transition in al la "build" in PP.

According to the docs, using [content addAnimation:trans
forKey:kCATransition] should have worked for slide transitions.  It didn't.
However, using the delegate method, augmented by an ivar enable flag, did
work.

Next, tried the delegate method for builds.  Didn't work.  It
transitioned in the entire layer stack (all sublayers of A or B) instead of
the single inserted layer. So I went back to using [B addAnimation:trans
forKey:kCAOnOrderIn] for builds.  That worked properly.

None of this makes any sense, other than the build-transitions being one
level deeper in the hierarchy than the side transitions.


Definition of "software development":  A series of experiments,
hopefully culminating in the desired result.

Re: How can a plug-in bundle get access to its own resources?

I understand that.  So does everyone else.  We also understand that your code 
base is large and that you don't want to change every existing class name or 
redesign your build system on every platform.  But nothing anyone has said so 
far requires that you do any of those things.  If you think you do, it's 
because you are labouring under some misunderstanding about Cocoa/ObjC.

All we're saying is that *for your ObjC classes*, you need the names to be 
unique across your entire process, and in practice that means prepending them 
with something.  For a plug-in system, especially if it plugs in to code in a 
third-party process, I strongly recommend that you use something akin to Java's 
reverse domain scheme, even though, as I say, that isn't the usual solution for 
Objective-C code.

I don't see why that would require the kind of changes you're indicating it 
would.

Right.  Yes, it will.  The framework versioning mechanism is just a variation 
on the usual symlink system used on most UNIX-like systems for shared 
libraries.  The only difference is that the structure is not flat (so whereas 
you might see e.g. "libcrypto.dylib" symlinked to "libcrypto.0.9.8.dylib", here 
it's the folders that are symlinked).

Ah, sorry, I see what you meant---you were talking specifically about the 
-mainBundle method itself.  I had misunderstood your sentence (I think perhaps 
a language issue---a native English speaker would probably have used "this" 
rather than "such", which has a somewhat different meaning here).

As you've been told already, you need -bundleForClass:.  The problem you are 
having with it is because you're misusing the Objective-C language and runtime, 
and you're doing that---you claim---because for some reason your Objective-C 
class names can't possibly be prepended with a unique identifier for each 
plug-in.  Quite frankly, I don't buy it; it shouldn't require changes to the 
build system on all your other platforms to achieve that, and it isn't 
complicated.

Kind regards,

Alastair.
