IBOutlets or property + binding

Maybe you can temporarily add similar lines to your code and see if you see
tooltips?
I know you know better, but I'll ask some obvious questions. (Yes, your
geneticBasisChanged code would seem to answer many of these questions, but
maybe not your other code, and when confronted with code that can't be
failing, I try to question obvious assumptions.)
* Are you sure your calls to setToolTip: are being performed?
* Are you sure the receiver is not nil at the time of the call?
* Does [myView toolTip] return what you passed to setToolTip:?
* Are you sure the receiver is the object you intended? For example, if you
log a button's address when you setToolTip:, and log the sender's address in
the button's action method, do you see the address you expect when you click
the button?
* Do you have any overlapping views that might be stealing the mouseEntered
event?
* I also wonder if there is some OS hack or defaults setting that is
suppressing tooltips in general. Do you see tooltips in other apps?
* How many views do you have that have tooltips? It *feels* like there is an
extra long delay the first time I bring up a tooltip, and I wonder if there's
some initial overhead that might increase with the number of tooltips.

Core Data: Simply set NSMigratePersistentStoresAutomaticallyOption in a Document?
Well, it's time to move my beta testers from 0.1.8 to 0.1.9 and this requires a Core Data database migration. Since the app requires 10.5, I can use Default Automatic Migration. Yippee. Up to this point, my NSPersistentDocument subclass had used the Persistence Stack which is built into NSPersistentDocument. However, this stack apparently does not create set NSMigratePersistentStoresAutomaticallyOption in its store. It looks to me like I need to override -managedObjectContext and implement that whole persistence stack enchilada just to set this one little, commonly-used option. Is there a shortcut? If indeed I need to implement the stack, where is the best place to splice in the pieces? I had been creating new documents from a wizard using -[NSDocumentController openUntitledDocumentAndDisplay:error:], and doing some configuration which required the moc at the end of -init. Now that doesn't work since I can't set a store in new documents before the fileURL has been set, which happens later. I'm imagining many ways to move things around, but I'd like to start out by doing it the *right* way. Sincerely, Jerry Krinock P.S.

Re: CALayer Transitions
None of this makes any sense, other than the build-transitions being one level deeper in the hierarchy than the side transitions. You're right. As I read the documentation over and over again it didn't make any sense to me at all. First I thought it's the language, since my mother tongue is german. But that was not the case.

Re: IBOutlets or property + binding
Arghh... I was beaten to an answer! :) Slow typing... Yeah, with bindings you will get a two-way connection. If you change your property's value programmatically, the stepper will update also. Instead of target-action you could set up an iboutleted property, connect stepper to it and observe that property for changes. This may be a more cumbersome approach in this case though.

Maybe you can temporarily add similar lines to your code and see if
you see tooltips?
Now we're getting somewhere. I thought my app's code was simple
enough that it essentially represented a simple test case, but of
course I was wrong. If I put Andy's code in as the -awakeFromNib for
my app delegate, the tooltip works fine. But if I copy and paste his
button creation code into my NSDocument subclass's -
windowControllerDidLoadNib: method, it does not work. That gave me
some traction. After commenting out various chunks of my code, I have
narrowed it down to a call that I make at the end of my
windowControllerDidLoadNib: method:
[window setContentSize:NSMakeSize(...)];
If I comment out this line, then the tooltip works. Aha. This led
me to suspect the custom NSView subclass that I am using as a content
view, and indeed, if I use that custom subclass as the content view in
Andy's code, it breaks the tooltip there too. So now we have:
@interface AKDocumentContentView : NSView
{ }
@end
@implementation AKDocumentContentView
- (BOOL)isFlipped { return YES; }
@end
- (void)awakeFromNib
{
NSWindow *testWindow = [[NSWindow alloc]
initWithContentRect:NSMakeRect(100, 100, 500, 500)
styleMask:NSTitledWindowMask
backing:NSBackingStoreBuffered
defer:YES];
NSRect contentFrame = [[testWindow contentView] frame];
AKDocumentContentView *newContentView = [[AKDocumentContentView
alloc] initWithFrame:contentFrame];
[testWindow setContentView:newContentView];
NSButton *testButton = [[NSButton alloc]
initWithFrame:NSMakeRect(100, 50, 100, 20)];
[testButton setTitle:@Hover Over Me];
[testButton sizeToFit];
[testButton setToolTip:@This is an NSButton];
[[testWindow contentView] addSubview:testButton];
NSView *testView = [[NSView alloc] initWithFrame:NSMakeRect(100, 100,
100, 20)];
[testView setToolTip:@This is a test view];
[[testWindow contentView] addSubview:testView];
[testWindow setContentSize:NSMakeSize(500, 600)];
[testWindow makeKeyAndOrderFront:self];
}
Commenting out the -setContentSize: call makes the tooltip work.
Commenting out the three-line block that replaces the window's content
view with the custom subclass makes the tooltip work. But if both
sections of code are live, as above, then the tooltip is broken.
Changing -isFlipped to return NO, however, makes the tooltip work
again. Also, moving the setToolTip: call to be after the -
setContentSize: call makes the tooltip work.
So it appears that when you set a tooltip on a view that is inside
a flipped content view, and then set a new content size for the
window, the tooltip gets lost somehow. The only reason I could think
of why this could be my fault was that my content view was not
resizing to fit the window properly, because of its springs; but I
added a -drawRect: call to it that just frames [self bounds], and it
is correctly resizing to continue to fit the window, so that is not
the issue.
Adding NSResizableWindowMask to the window's style mask is also
interesting. In this case, if the -setContentSize: call is commented
out, the tooltip starts out working and stays working even when the
user resizes the window. But if the -setContentSize: call is left in,
the tooltip starts out broken and remains broken, even after the user
resizes the window. So whatever the issue is with -setContentSize:,
it is persistent.
So, is this a bug in AppKit, or are content

Only NSCollectionView. But, that is a good question; how would one know they
should call super? In general, I think people should *always* call super,
unless they have some specific reason not to. Assuming that super may or may
not do anything is simply an implementation detail -- in the future we may add
code that does something.
Maybe for this case we should add the declaration to NSCollectionView and state
that it overrides the method to do more work. The .NET framework tends to do
this to let people know when that happens, and it might be nice for AppKit to
do it too.
The docs often comment about calling super. In NSView's case, they do
for beginDocument, beginPageInRect:atPlacement:, drawRect:, endDocument,

I don't see one, I don't call super. At least one Apple example also doesn't:
http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Conceptual/
EventOverview/MouseTrackingEvents/MouseTrackingEvents.html
Should one call super for all the viewWill/Did methods?
My opinion is yes. Please log a documentation bug asking to be clarified (you
can copy my email into it).

Re: Help with Background Tasks
List, OK to make my request a little more detailed. In my tableview cell for row at index path method I make several URL requests that fill in a cell within a section. E.G section 1 - row 1 (1st url request) section 1 - row 2 (2nd URL request), etc... section 2 - row 1 (URL request Same as url request in section 1 but different data supplied) section 2 - row 2 (URL request Same as url request in section 1 but different data supplied) Obviously I want each URL request as it ends to update the correct index path table cell. I would like to send index path as one of the parameters so that when I perform the selector in background. I can modify that specific cell with that result. The method below only allows me one object, I'm not sure if the withObject:withObject: method will sole the problem if i create a compound selector with the @selector. [self performSelectorInBackground:@selector(MakeURLRequest:) withObject:URLRequest]; All that said I would like to use URLconnection instead (as jens points out) they are asynch but again I have the problem of allocating the responses back to the correct index path object.

Cocoa's networking APIs are asynchronous, so you can start a download using NSURLConnection and it will run in the background and notify your delegate when it's complete. You almost never need to start threads in Cocoa programming. This can be hard to adjust to if you come from other frameworks, esp.

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?
Oh -- another thing. Does your subclass of NSCollectionView override:
(void)viewWillMoveToWindow:(NSWindow *)window {
but not call super? If not... call super! Your classes should always call
super if it is defined in a superclass, unless you have a good reason to
hide the super's behavior.
corbin
This was the problem, thank you. This is a difficult bug to find in code
someone else wrote. This makes me almost wish there was a gcc flag for it
(-Woverride-no-super).
FWIW, this is a compatibility problem we (AppKit) try to avoid. An update to
the OS shouldn't break one's app. Right now it is (obviously) too late to
change AppKit for SnowLeopard, but please do log a bug so we can do something
about it (it will probably amount to a tech note or release note or
documentation change for NSCollectionView).

NSTextView, Bindings, and Display Updates
Hi All, I'm having a strange behavior with an NSTextView bound through Interface Builder to a Core Data backing. The textView is part of a standard master-detail setup, and is not updating its value when the selection is changed in the master list. The value only displays after the mouse has entered the textView's frame. It stays there until the master selection changes, at which point I have to wave the mouse through it to get the new value to appear. Any ideas?

Trouble finding bounding rect of NSAttributedString
Hi everyone, I've been struggling for several hours to get the bounding rectangle of an NSAttributedString when drawn at a particular width. I have an NSTextView that I need to resize dynamically. NSTextView appears to resize itself as I add text, but I also need it to shrink itself as I delete text. Here's what I've tried: [myAttributedString size] [myAttributedString boundingRectWithSize:NSMakeSize(desiredWidth, FLT_MAX) options:NSStringDrawingUsesDeviceMetrics]; [[myTextView layoutManager] usedRectForTextContainer:[myTextView textContainer]] [[myTextView layoutManager] boundingRectForGlyphRange:NSMakeRange(0, [myAttributedString length]) inTextContainer:[myTextView textContainer]] ... and a few others I've been over the documentation for NSAttributedString, NSLayoutManager, and NSTextContainer, and I've tried just about everything that looks like it might give me what I'm looking for. However, I've obviously missed something pretty fundamental to getting my string's rect. Any pointers? Thanks!

Re: IBOutlets or property + binding
target/action is inappropriate since no action is needed at the time the value was changed. Instead, once the user clicks a button I compute something hence I read the values from the steppers and stuff. But that doesn't change much does it :) Cheers, Chris On 19.11.2009, at 18:51, Karolis Ramanauskas wrote: Arghh... I was beaten to an answer! :) Slow typing... Yeah, with bindings you will get a two-way connection. If you change your property's value programmatically, the stepper will update also. Instead of target-action you could set up an iboutleted property, connect stepper to it and observe that property for changes. This may be a more cumbersome approach in this case though.

Re: Trouble finding bounding rect of NSAttributedString
Good point.
When I print out the size or rect that these return, I invariably get either
{0, 0} or something absurd like {{1.17076e-318, 2.29357e-314}, {2.30359e-314,

ColorSyncDeprecated.h in OSX - 10.6
Hi, Does anyone have any idea where the new functions for ColorSyncManager (presumably 64bit focused) are documented? The only information I can find lists the new functions but does not document them. (Application Services Reference Update. dated 2009-8-28 lists the names but has no reference links to either the complete description or reference documentation.) The ColorSync.framework (C-)headers are completely changed from the earlier X-Code /Leopard release In addition to this, a huge number of fundamental ICC elements seem to be probably(?) deprecated now. (I am making the dprecation assumption although I can find no specific record in anything except headers = In X-code 3.2.1 they are now shown in a new header file labelled ColorSyncDeprecated.h.) Worryingly, the (probably?) deprecated elements include a large quantity of 'enum's which are fundamental elements in ICC versions from at least 2.1 onwards. I have seen some info on data 'type' issues with 'enum's in 64bit code in 64 bit Transition Guide for Cocoa. An updated version of ColorSyncManager reference is a possible missing link (last update was 2005). Are we just seeing Apple getting a bit ahead of themselves with the early SnowLeopard release and not tying up the loose-ends in ColorSync for X-Code? A link to the new documentation or even just a date for the documentation release would be helpful (Apple please?)

NSStatusItem with agent
Hi I am developing launch agent which creates NSStatusItem. When I am launching my agent by myself using launchctl load com.company.MyAgent.plist then I dont have any problem, I see NSStatusItem in menu bar and I can set focus on it. If I put my agent to /System/Library/LaunchAgents and restart computer, then after restart I cant set focus( I am clicking on it) on my NSStatusItem. All other functionality of my agent is working.

NSStatusBar *bar = [NSStatusBar systemStatusBar]; NSStatusItem* theItem = [bar statusItemWithLength:NSVariableStatusItemLength]; [theItem retain]; [theItem setTitle: NSLocalizedString(@Tablet,@)]; [theItem setHighlightMode:YES]; Am I doing something wrong?

Controlling cocoa windows hit test
Hi, I'm looking for a way to control hit testing on a cocoa transparent window. The default behavior, as I understood it, is that if a pixel is not entirely transparent, then the click occured in the window. I would like to have more control over this, so a click in my custom drop shadow don't cause my window to become key. Can you think of a way/hack to make this happen, something like kEventWindowHitTest in carbon ?

need to find exact WiFi encryption method
Hi, I have used securityMode method in CWNetwork class of CoreWLAN framework to find the encryption used in the current Airport WiFi connection. I am getting return value kCWSecurityModeWPA_PSK. My problem is I have 2 WiFi network, 1) WPA - PSK - TKIP 2) WPA - PSK - AES But the Mac securityMode API is having only one return value for both these network ie kCWSecurityModeWPA_PSK. The same is with WPA2 also. IF any one knows a way to find the exact type of encryption used in WiFi Airport connection , Please let us know as soon as possible. I have tried to find in preference files, but every were its written as WPA - PSK only, no where I am able to find what type of encryption exactly is used ie TKIP or AES .

Re: Trouble finding bounding rect of NSAttributedString
On Nov 19, 2009, at 2:39 PM, Dave DeLong wrote:
When I print out the size or rect that these return, I invariably get either
{0, 0} or something absurd like {{1.17076e-318, 2.29357e-314}, {2.30359e-314,
2.1224e-314}} (that's just running the rect through NSStringFromRect())
Make sure the receiver (the NSAttributedString) isn't nil. The Obj-C runtime
gives undefined results for a struct-based method return value if the receiver
is nil; so you'll end up with garbage like this. (This is because it doesn't
know at runtime how large the struct is, so it can't safely fill it in with
zeroes.)
Put in something like NSAssert(str!=nil, @str is nil); before the call.

tiffs on pasteboard
I'm trying to read a TIFF off the pasteboard, but it doesn't seem to work for me. What I'm doing is going into Finder, finding a TIFF file and Command-C it. Among other types I then find on the pasteboard are: NeXT TIFF v4.0 pasteboard type and public.tiff If I take either of those from the pasteboard and write the NSData object to a file: [content writeToFile:@/tmp/foo.tiffatomically:YES]; or else if I make an NSImage from the data: [[NSImagealloc] initWithData:content] and display it in an NSImageView then I always see the generic TIFF icon, i.e. the one with a photo of a child scattered on the table, with a loupe on top of it. The same thing happens for JPEGs, GIFS and PNGs, but not for com.apple.icns. If I take the com.apple.icns, it displays correctly.

The actual socket I/O happens in a background thread owned by CFNetwork; I don't think that thread will stop reading data just because your callback on the main thread hasn't returned yet. It just means that, when you do return, you'll immediately get a bigger chunk of data. I've seen this general question of rate limiting asked on the macnetworkprog list. IIRC the answer is that Foundation and CFNetwork don't really give you the tools to do it. You'd have to write your own code using low-level BSD sockets APIs. :-P —Jens___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Core Data: Simply set NSMigratePersistentStoresAutomaticallyOption in a Document?

Hmmm. When I tried that this morning I only got 19. Among the additional 17,
I found this:
http://lists.apple.com/archives/cocoa-dev/2008/Aug/msg00767.html
Summary: There is no need to muck with NSPersistentDocument's built-in and
bug-free Persistence Stack. Happy Day! All you do is override
-[NSPersistentDocument initWithContentsOfURL:ofType:error:]. I submitted
document feedback suggesting this to the Core Data Model Versioning and Data
Migration Programming Guide.
Thanks, Matthew.
The code in that post had issues and didn't quite work, so I fixed it up and it
now seems to just work now for all three cases (1) oldest docs saved with old
model (2) old docs with new model (3) new docs. In case (1) the old file
remains with a tilde suffix, as expected. In case (3), the method doesn't even
run. But when it does, it handles errors properly :)
So, the answer to the question: How to enable Default Automatic Migration in a
Core Data document-based app, is...
Simply drop the following override into the NSPersistentDocument subclass:
- (id)initWithContentsOfURL:(NSURL*)url
ofType:(NSString*)typeName
error:(NSError**)error_p {
// NSPersistentDocument's built-in Persistence Stack seems to create a store
// without setting the NSMigratePersistentStoresAutomaticallyOption, so
// automatic migration just doesn't work. The following code, which runs
// only for existing documents, works around that problem.
NSError* error = nil ;
NSArray* bundles = [NSArray arrayWithObject:[NSBundle mainBundle]] ;
NSManagedObjectModel* mergedMOM = [NSManagedObjectModel
mergedModelFromBundles:bundles] ;
NSPersistentStoreCoordinator *psc = [[NSPersistentStoreCoordinator alloc]
initWithManagedObjectModel:mergedMOM];
NSDictionary *optionsDictionary =
[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES]
forKey:NSMigratePersistentStoresAutomaticallyOption];
id store = [psc addPersistentStoreWithType:NSSQLiteStoreType
configuration:nil
URL:url
options:optionsDictionary
error:error] ;
// If migrating the document from and older to the current model was
necessary,
// it is now all done! The addPersistentStoreWithType: will have
renamed the
// old file with a tilde on the end and created a new, migrated file at the
given
// URL. So now, when we invoke super, it will open the new file and just
work.
// Very nice.
if (store) {
self = [super initWithContentsOfURL:url
ofType:typeName
error:error] ;
// The above method will return nil if it fails.
}
else {
[self release] ;
self = nil ;
}
if (!self error_p) {
*error_p = error ;
}
return self;

Re: Where are the interface builder components?
OK, so you want one of these controls yourself? Well, let's imagine you're going to sit down and write one for your app. Are you honestly telling me that you expect to end up with highly reusable code that could be placed in a framework like Cocoa, and you'd be happy to ship to a large number of other developers? Or (and far more likely) that you'll have implemented only the bits of functionality your own app needs and left plenty of holes to fill? Please i'm not trying to offend anyone here, i was just questioning... but since you ask. I try my best to design my classes with the re-usability in mind, also to the best of my knowledge of the language at the time of design, mostly because I do not like to have to rewrite things, it's a waste of time, efforts and money... occasionally I will rewrite a class to improve it with new acquired knowledge and techniques yes, for instance when i learned that i could iterate thru a collection using a for loop instead of while loop coupled with an iterator, i did change most of my classes to reflect that ease of use. same thing for when I learned of properties and KVM coding. Additionally I always write my code with someone might need to use this kind of approach, it takes me a little more time but it's worth it in the end. If I was to provide quality development tools to my users, I would make sure my employees have that mindset when hacking together a class, yes, because the time spent un-mixing the mess afterwards to release proper components is just to costly. 1: it takes them away from the creative bench to think of new features 2: it doubles the initial effort therefor doubling the cost, in human hours. Unfortunately for me right now i do not believe I have proper and all the handles on cocoa to create my own controls, but i'm getting there My first controls will probably have holes and missing features, and might respond to specific needs, but then again i'm one guy with less than a year of experience with cocoa. Tho I try my best to measure up, I'm not Apple. This thread of emails want not intended to bash Apple for not doing their work, I just needed to understand why the components are not already available in the toolbox when it seemed logical to me that they should of been there with the release of the operating system along with all the new features so application developers could take full advantage of it.

resizing PDF obtained from dataWithPDFInsideRect:
I've got an image that's generated using a large integer coordinate space. When it's drawn to the screen, its coordinates are converted to screen coordinates. Unfortunately, the screen coordinates are assumed to be integers and it's not a simple fix to use floats (the code is common to Mac, Windows, and X Windows). The code will be eventually rewritten, just not anytime soon. The conversion to screen coordinates is causing stair stepping in connected lines and other oddities when exporting to PDF. As a temporary solution until the code is rewritten, I've created a subclass of my view that's sized at the large coordinate space's dimensions specifically for rendering the image to PDF. However, I can't seem to resize the PDF data down to the more manageable screen view's dimensions when saving to disk. I've tried creating an NSPDFImageRep from the PDF data and resizing it but it has no effect on the saved to disk image (I guess setSize: does not affect the original data). What I end up with is a PDF file with large dimensions that overwhelms whatever application I'm placing it into. What I ended up doing is creating an NSView subclass that simply draws the PDF at the size I want and returns the PDF data from that. This works but is there a better way of resizing the dimensions of PDF data or is the size the size that it's generated at and there's no changing it? Also, I allow the user to export the image as a bitmap and even override the dimensions. I create an NSImage from the PDF data, resize the NSImage, then save the TIFF representation to the bitmap format I want. This works in Leopard but no longer works in Snow Leopard. I read the tech note about changes to NSImage and caching but I had no luck with the different caching methods. I ended up creating an NSImage at the desired size, locking the focus, drawing the PDF data at the desired size, unlocking the focus, then saving the TIFF representation. Is there a better way? And finally, is there a way to change the resolution of a bitmap from 72dpi to say 300dpi? My users want to be able to specify the dimensions of the exported bitmap in inches and the resolution. They want to be able to place their 1800 pixel wide TIFF file into Word and it show up 6 inches wide (@ 300dpi) instead of 25 inches wide (@ 72dpi). Not a huge deal because I still recommend our users use PDF but some of them have legacy apps that don't support PDF. The example I was able to find on this created a new NSBitmapImageRep and copied the image data into it and then set the size.

initializer methods
After many years of using procedural programming languages, I am trying to
learn Cocoa. Today I am reading the Apple document The Objective-C Programming
Language dated 2009-10-19. On page 46 I read the following:
This is an example of what not to do:
+ (Rectangle *)rectangleOfColor:(NSColor *) color
{
self = [[Rectangle alloc] init]; // BAD
[self setColor:color];
return [self autorelease];
}
However, on page 49 I read the following:
There are several constraints and conventions that apply to initializer methods
that do not apply to other methods:
.
.
.
• You should assign self to the value returned by the initializer.
This is because the initializer could return a different object than the
original receiver.
Could someone please explain this apparent contradiction?

Because the first method isn't an initializer method, it's a Class
method, a convenience method for returning another object.
initializers are the instance methods which conventionally start with
init (look a bit back from where you were on page 49) and those methods
should assign to self because self in that case means the object you are
initializing (and returning).
For class methods, self is the class, in that example at the top you're
not returning the class or a class object, you want to return an object
OF the class, so self is just the wrong thing to use.
Remember that a '+' at the start of a method signature denotes a class
method, a '-' at the start of a method signature denotes an instance
method.

There's no contradiction because +rectangleOfColor: is not an
initializer method. Initializers 1) start with init and 2) are instance
methods, not class methods (start with a - not a +). Page 49 is talking
about implementing custom initializers, rectangleOfColour is not one.
Good luck!

Re: How to avoid text distortion
Hi Dave, I think my case is some thing related with anti-aliased text. Because as per your suggestion I made a screen shot and saved In my Mac Book. I have transfered the saved png image to my Windows PC to post in llist. But interestingly the screen shot when viewed in Windows don't have that problem. So I think no use in posting that image. Text are crystal clear. but the same screen shot when viewed in my Mac book again showed the same problem. One more point is that I am using Xcode 3.2 in Snow Leopard (Version 10.6.2) and in System Preference - Appearence - Use LCD font smoothing when available option is disabled , again font and text are displayed perfectly ie with out any distortion. If I enable this option which is enabled by default this problem occurs. But this problem happens only with the application I have developed.

Re: Trouble finding bounding rect of NSAttributedString
Your question has caused me to dig deeper...
It seems that when I handle both the NSViewFrameDidChangeNotification and the
NSTableViewSelectionDidChangeNotification notifications, the attributedString
of the textView's layout manager is nil.
This is very interesting... Here's a bit more of my setup. I have an
NSTableView, populated by an NSArrayController. The textView's data is bound
to the arrayController's selection.data (which provides an RTF NSData object).
That works as expected. I observe the ViewFrameDidChangeNotification on the
textView, so that as the user types in text and the textview grows, I can also
resize the superview accordingly.
I was listening to the selectionDidChange notification of the NSTableView,
because (I've observed) when the data to be shown in the textview is smaller
than the current size of the textview, it does not resize down to fit the
content. This is the behavior that I'm looking for.
However, in both of these methods, the attributedString of the textview is nil,
thus giving me the strange results I'm seeing.
What would be the appropriate way to get the behavior I'm looking for?
Thanks,
Dave

When I print out the size or rect that these return, I invariably get either

NSStringFromRect())
Make sure the receiver (the NSAttributedString) isn't nil. The Obj-C runtime
gives undefined results for a struct-based method return value if the
receiver is nil; so you'll end up with garbage like this. (This is because it
doesn't know at runtime how large the struct is, so it can't safely fill it
in with zeroes.)
Put in something like NSAssert(str!=nil, @str is nil); before the call.

How to avoid the movie distortion ?
Hi, all I implement a simple movie player using QTMovieView. But some movies will be distorted by reason of the proportion of the Height and Width. How to avoid the movie distortion? Thanks.

If I enable this option which is enabled by default this problem occurs. But this problem happens only with the application I have developed. I suspect you are using a layer-backed view. NSTextFields with no background color will display without sub-pixel anti-aliasing on layer-backed views. If you want the text to have sub-pixel anti-aliasing, give the text field a background color. -- Rob Keniger ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
