EXC_BAD_ACCESS on NSImageView::setImage
I have a window that contains a NSImageView that displays pictures. here is the code : =CODE= NSBitmapImageRep *rawPic = [[[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:thisFrame.width pixelsHigh:thisFrame.height bitsPerSample:8 samplesPerPixel:3 hasAlpha:NO isPlanar:NO colorSpaceName:NSCalibratedRGBColorSpace bitmapFormat:NSAlphaFirstBitmapFormat bytesPerRow:0 bitsPerPixel:0] autorelease]; unsigned char *DestinationRawData = [rawPic bitmapData]; memcpy(DestinationRawData, CurrentFrame, SzCurrentFrame); [self RGB2BGR:DestinationRawData Sz:SzCurrentFrame]; NSImage *NewDisplayImage = [[[NSImage alloc] initWithSize:thisFrame] autorelease]; [NewDisplayImage addRepresentation:rawPic]; [ExternalView setImage:NewDisplayImage]; =CODE= The ExternalView display correctly what i want for a while, no memory leak appears but after few seconds the program gives me a bad EXC_BAD_ACCESS. After commenting the last line (setImage) there is absolutely no crash. Thinking of a side-effect i checked all sizes and everything seams to fit. I also tried to remove the autorelease and replace them by some release after the set image but nothing seams to work. Can anybody see something wrong ? Is there any other way to do what i m doing ? Thanks for the peolple that will help me. Sincerely, -- I. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: EXC_BAD_ACCESS on NSImageView::setImage
I just change my NSWindow from NSBackingStoreBuffered to a NonRetain one and my application do not crash anymore. Unfortunatly, as expected, my window is clipping how ever i just realize that the crash might have a relation with the NSWindow double buffer mechanism. So my solution to the problem was instead of replacing the NSImage using setImage, i grab directly my NSImage from the View, then pick the representation and write directly into it. It is as a matter of fact, a way better effective way of doing what i was doing and it's avoiding all my release problems. thx -- I.

CIImage resize optimisation
Hello, I use QTKit to grab an image from my webcam. Then i need to resize it into a smaller image. Going from My CIImage, i use two filter "CILanczosScaleTransform" and "CICrop" to get my image at the correct size. (640x480 to 320x240+crop). Doing only that, my CPU go up to 30% of usage while it is at 12% without the transformations. I have a set of C function that works on Bitmaps that is very specialized to what i m doing, and would allow me to earn a lots of unnecessary transformations (on windows that makes my CPU usage to raise to +5% max only) ... but here the problem, the rendering of CIImage to a bitmap is worse than the filter usage. here my question, Is there a way of accessing directly the CIImage representation so that i can pick my pixels very quickly ? the aim is to be very efficient of course ... thanks to all that will help me. -- Dev _______ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Matching braces and [NSTextView selectionRangeForProposedRange:granularity:];
I'm currently trying to match braces in a text editor and intend to use selectionRangeForProposedRange:granularity: for that. While I don't see any problem in finding the matching brace, I'm a bit surprised by the way this method is called repeatedly. So far, I don't see a good way to tell a double-click occurred and just a double-click: If you double-click and release the mouse button, this method is invoked 2 times (from the double-click event). If you double-click and do not release the mouse button, this method is invoked 1 time but if you move the mouse cursor, it is invoked again and the number of clickCount is still 2. It might be possible to use some time measures to differentiate these 2 paths but this does not look like a good solution at all.

[NSTextView] Shift left / Undo manager
I am currently busy re-inventing the wheel in the form a code editor. I support Shift Left and Shift Right. I would like to support Undo on Shift Left. I'm wondering how this should be done as this operation modifies both the selected range(s) and the text. I searched the archives, the NSTextView header, documentation, looked at some source code. I am able to support the undo operation for the text changes but the selected range(s) is/are not reverted to the correct value(s). From what I can see, Xcode (on Tiger) does not handle the selection correctly in this case either (though the result is better than mine) Any idea? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

[Performance issue] Resizing an alert sheet => blinks
Is it the intended behavior that resizing an Alert Sheet in Mac OS X 10.5.8 on a MacBook Pro produces a lot of blinking? I have a custom alert sheet that can be resized and when I resize it on a MacBook Pro (either 9400 or 9600 GPU), the resize operation produces flicking. I tried with some Apple's applications and with the standard save sheet and it's also blinking (less though). I removed almost every widget in the sheet, disabled the default button, it's still blinking. This does not happen with standard window and I am not experiencing this phenomenon on a PowerMac G5 running Mac OS X 10.4.11. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

It's a bit as if there was a patchwork of rectangles and a random set of these rectangles would not be redrawn when the window size increases by 1 pixel and then another set for the following pixel. I used Quartz Debug to check that there was not too much refresh and it looks fine. I tried both with a 64 bit executable and a 32 bit executable. Finally, I tried running the same code on Snow Leopard on the same MacBook and it's working correctly there. So definitely an issue with Leopard.

Limiting the area of an NSShadow
Hello, I'm trying to mimic the background of Time Machine's large On/Off switch ( http://zcr.me/l/n2 ) by drawing it via code. This is my code so far: cellFrame.size.height = 27; NSBezierPath *border = [NSBezierPath bezierPathWithRoundedRect:cellFrame > xRadius:5.0 yRadius:5.0]; [border setLineWidth:1.0]; [[CZColor colorWithCalibratedWhite:0.246 alpha:1.000] set]; NSGradient *backGradient = [[NSGradient alloc] > initWithStartingColor:[CZColor colorWithCalibratedWhite:0.387 alpha:1.000] > endingColor:[CZColor colorWithCalibratedWhite:0.73 alpha:1.000]]; [backGradient drawInBezierPath:border angle:90.0]; NSShadow *innerShadow = [[NSShadow alloc] init]; [border addClip]; [innerShadow setShadowColor:[CZColor colorWithCalibratedWhite:0.0 > alpha:0.60]]; [innerShadow setShadowOffset:NSMakeSize(0.0, -0.75)]; [innerShadow setShadowBlurRadius:1.5]; [innerShadow set]; [border stroke]; Note: CZColor is a subclass of NSColor with no modifications, only additions. It shouldn't cause any issues. This code produces the following: http://zcr.me/l/n3 The result is close to Apple's Time Machine image, but not quite: the shadow is drawn all the way around the bezier path, and not just on the top. Is there a way for my to limit the NSShadow so that it only draws on the top part of the bezier path?

I haven't found a method to access the contextual information in NSSavePanel, NSPanel, NSWindow. Typically the delegate is the controller that calls beginSheet... so whatever it passed as contextInfo is available to any delegate method because it's something internal to this controller object. Can't disagree with that. If you've organised your code in such a way that the controller is not the delegate, you might want to reconsider that.

Commit Editing Changes as I Type
I have two controls (NSTextField and a NSTableView column) that are bound to the same attribute in core data. I've set up a timer that starts after the NSTextField starts editing and I'd like it to periodically commit the editing as the user is typing. If the user hits the Enter key I do see the text in both places but I want those updates to go as the user is typing so the text will show in both fields as the typing is happening. When my timer launches I tried calling: [myTextField commitEditing] // but this didn't work, nothing happened.

Better Way to Add an Entity to an ArrayController
I have a core data app with a model where there is a one-to-many relationship between CD and Track (CD has an NSSet called tracks). The tracks are shown in an NSTableView and the content set is managed by an NSArrayController. To manually add a track the user presses the add button which runs the "add:" selector of the arrayController. Right now, to programmatically add a track I do: [arrayController performSelector:@selector(add:) withObject:nil afterDelay:0.0]; That doesn't feel right to me. I want to create a new Track entity and add it to the CD attribute tracks which is an NSSet . I **think** I have to do the following but I don't know how exactly: 1) "willChangeValueForKey" to the CD entity, tracks attribute, from the managedObjectContext to let it know I'm going to change the tracks attribute 2) create a new Track entity 3) add that new entity to the tracks NSSet attribute in the CD entity 4) "didChangeValueForKey" That's what I've been trying to do and it's not working. I can get the tracks attribute. I retrieve it as an NSMutableSet. To create the new Track entity with the following I get a nil: Track *newTrack = [[Track alloc] init]; Assuming I do successfully create a new Track entity do I just add it to the tracks set?

Re: Help with NSData dataWithContentsOfURL
Thanks Graham, here's what I'm thinking. The documents for my app are fileWrappers. Before the document is saved for the first time I can copy the files to a temp folder and during a save move them into the fileWrapper.

NSViewAnimation vs Distributed Notification: Bug?
[Q] Is there a known bug in NSViewAnimation on Mac OS X 10.4 when it
comes to Distributed Notifications?
Scenario:
-
If I animate a window resizing through a NSViewAnimation, some
Distributed Notifications are only taken into account after I click
in the window resized through a NSViewAnimation.
If I animate the window with setFrame:dispplay:animate:, the problem
does not occur.
--->8--->8--->8--->8--->8--->8--->8---
// This does not work correctly
tAnimationDictionary=[NSDictionary
dictionaryWithObjectsAndKeys:IBwindow_,NSViewAnimationTargetKey,
[NSValue valueWithRect: tNewWindowFrame],
NSViewAnimationEndFrameKey,
nil];
tAnimation=[[NSViewAnimation alloc] initWithViewAnimations: [NSArray
arrayWithObject:tAnimationDictionary]];
if (tAnimation!=nil)
{
[tAnimation setAnimationBlockingMode:NSAnimationBlocking];
[tAnimation setDuration: 0.15f];
[tAnimation startAnimation];
[tAnimation autorelease];
}
// This works fine
[IBwindow_ setFrame:tNewWindowFrame display:YES animate:YES];

On Feb 28, 2010, at 12:35 AM, Steven Degutis wrote: Firstly, you do not need to check if tAnimation is nil, since sending a message to nil is valid in ObjC. So I would personally remove that if() and just de-indent all the code that's inside it. Actually, in the real implementation there's an else after the if. Secondly, I *think* what you're running into is the fact that "blocking mode" means the main thread blocks, and thus does not receive any distributed notifications. The second snippet of code (the one that works fine) does not animate on the main thread, thus everything works correctly. If you want to use NSViewAnimation for some reason (but I wouldn't), then you can change the mode away from blocking-mode to something more background-thready. The more I investigate this, the more it looks also linked to having 10 NSTimer with a 1/16.0f period. _______ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

But i cannot change it in the tableView,it means that when i change it it
displays but then it has nothing.How

[NSImage] Bug in System Preferences?
I'm currently playing with a screen saver. Problem: It draws correctly in fullscreen mode or in SaverLab but does not in the preview mode of the 'Desktop & Screen Saver' pane of the System Preferences. Basically, in #fail mode, it draws the first frame and then does not refresh. It works on Mac OS X 10.4 but does not on Mac OS X 10.5 and 10.6. Details: An animation frame is drawn in - [ScreenSaverView animateOneFrame] by drawing a NSImage using the - drawInRect:fromRect:operation:fraction: method. The NSImage contains one bitmap representation. I have access to the buffer of the bitmap representation and I update it for each new frame. What I've checked: -- o The problem is not with the size of the preview view, it works fine with this size, I tested it in SaverLab and in a custom Screen Saver testing app. o The problem is not with the NSRect parameters passed to the drawInRect:fromRect:operation:fraction: method. I've traced their values in gdb. o The problem is not with the bytes buffer not being updated, I checked in gdb that the values were correctly updated. o The problem is not with the view not being refreshed. I draw a rectangle with an increasing lighter color (for testing purpose) before calling the drawInRect:... method and the rectangle color is correctly updated. Where I think the problem lies: --- There must be some kind of (annoying here) optimization made by the Cocoa APIs. Since this works in fullscreen mode, it must be an optimization not enabled in fullscreen mode (and which was not in Mac OS X 10.4). QUESTION: - What can be done to address this behavioral incoherence in System Preferences? Code snippet: - Here is how the NSImage and NSBitmapImageRep are created (self is a NSView subclass instance): imageRect_=[self bounds]; realWidth_=(((unsigned long) floor(imageRect_.size.width))/ DIVIDER)*DIVIDER; origin_=imageRect_.origin; origin_.x=origin_.x+((unsigned long) (imageRect_.size.width- realWidth_))/2; imageRect_.size.width=realWidth_; pixelHeight_=imageRect_.size.height; imageRep_ = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide: realWidth_ pixelsHigh: imageRect_.size.height bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:NO colorSpaceName:NSDeviceRGBColorSpace bytesPerRow:0 bitsPerPixel:0 ]; buffer_=[imageRep_ bitmapData]; image_=[[NSImage alloc] initWithSize:imageRect_.size]; [image_ addRepresentation:imageRep_]; _______ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Hi- This isn't a bug, and your workaround could break under you at any time. If you think about what has to happen, you'll realize you cannot just have permanent direct access to the backing store. The image has to be colormatched and possibly uploaded to the graphics card, for example. How are the frameworks to know if you toggled a bit and that work must be redone? The basic CG model for an image is that it's immutable. Thanks for the hints. I tried them this weekend. When working with NSBitmapImageRep, calling -bitmapData is a signal that you may be editing the data. It is not repackaged until the bitmap is drawn, or somesuch. It's illegal to just stash a pointer to the data and use it arbitrarily later - that won't necessarily be the same data as now backs the image. This is described in the 10.6 AppKit release notes. Calling -bitmapData works on Mac OS X 10.5, it does not work on Mac OS X 10.6. On 10.6, it's slow and the data gets zeroed. Bug? In CG, you may be interested in the relationship of CGBitmapContext to CGBitmapContextCreateImage. The latter makes a copy-on-write vm copy of the data from bitmap context. So it's cheap until real copying is forced by a write to the context data. I tried this solution and it's way too slow (or I'm doing it incorrectly). Having to create a CGImageRef and then releasing it is killing the framerate. Basically, the only solution to get a decent framerate (25 fps) and a real refresh is to: - call -bitmapData on Mac OS X 10.5. - call lockFocusOnRepresentation: on Mac OS X 10.6. _______ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Calculating file size
Hello,
I was wondering what was the best way to calucate folder size with cocoa? I
was able to do this but it does not include resource forks:
#import
int main() {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSString *path = [@"/Folder" stringByExpandingTildeInPath];
NSDirectoryEnumerator *e = [[NSFileManager defaultManager] enumeratorAtPath
:path];
NSString *file;
unsigned long long totalSize = 0;
while ((file = [e nextObject])) {
NSDictionary *attributes = [e fileAttributes];
NSNumber *fileSize = [attributes objectForKey:NSFileSize];
totalSize += [fileSize longLongValue];
}
printf("Total size: %lld\n", totalSize);
[pool release];
}
or from the example in documentation
- (IBAction)calculateSize:(id)sender { NSFileManager *fileManager =
[NSFileManager defaultManager]; NSString *path = @"/Folder"; NSDictionary
*fileAttributes = [fileManager fileAttributesAtPath:path traverseLink:YES];
if (fileAttributes != nil) { NSNumber *fileSize; if (fileSize =
[fileAttributes objectForKey:NSFileSize]) { NSLog(@"File size: %qi\n",
[fileSize unsignedLongLongValue]); [label setIntValue:[fileSize
unsignedLongLongValue]]; } }
But I was unsure on how to traverse the entire file tree within that
directory, and give the same size results as the finder.
Thanks,
-Mike

Actually, the behavior is documented in the Cocoa Notifications programming topic: It is possible for an observer to register to receive more than one message for the same notification. In such a case, the observer will receive all messages it is registered to receive for the notification, but the order in which it receives them cannot be determined. Thanks for the pointer. It would be nice to have this explanation available in the description of the addObserver:selector:name:object: as it might be where one could expect to find it. I filed an enhancement suggestion. The current behavior makes it possible to implement architectures where a client could take "more action" for any given notification by registering more than once. Not supporting this pattern would make such a pattern significantly more inconvenient to implement. As well, any kind of a coalescing in the notification center is going to increase the complexity/overhead of the observer and, in particularly, might likely impact notification delivery speed (or, alternatively, require the notification center to use a bunch more memory to differentiate between "set of registered observers" and "list of observers that I actually deliver stuff to").

I think it would just require to make the search once on registration, not every time a notification is sent. Assuming that your statement is made in light of trying to avoid the bloat I alluded to in the previous paragraph, this would lead to some very surprising behavior.

AddressBook (Repost from objc-language)
Hi! I am reposting this as I mistakenly sent it to objc-language...oops. Documentation for ABAddressBook exposes a new method for 10.5: [ABAddressBook addressBook].(ABAddressBook Class Reference) Doc says that it "Returns a new instance of ABAddressBook". As I am in need of using a "private" addressbook for a project, I thought this would be perfect. With a quick test I attempted: ... ab = [ABAddressBook addressBook]; //ab= [ABAddressBook sharedAddressBook]; ABPerson *aPerson = [[[ABPerson alloc] init] autorelease]; [aPerson setValue:@"Remy" forProperty:kABFirstNameProperty]; [aPerson setValue:@"Lebeau" forProperty:kABLastNameProperty]; [ab addRecord:aPerson]; [ab save]; ... What I found out was that both sharedAddressBook and addressBook accomplished the same thing, that is adding a new person into my existing user addressbook, as opposed to generating a new addressbook... Did I misunderstand the documentation? TIA! Jeremy ___________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

[NSOpenPanel] How to disable folder selection but still access their contents?
Solution not found in the cocoabuilder archive. Problem: I have a list of files and folders. I can add items to this list through a standard NSOpenPanel dialog. When a folder is already in the list, I want to prevent the user from selecting it from the NSOpenPanel dialog. I can do this with: - (BOOL) panel:(id)sender shouldShowFilename:(NSString *) inFileName; The problem is that this prevents the user from selecting a file within this folder from the NSOpenDialog. Question: - Is there a way to prevent a folder from being selected but still allow a file within this folder to be selected? I could use - (BOOL)panel:(id)sender isValidFilename:(NSString *) filename; and always allow to select the folder but I want the user to know that the folder can not be selected and not just discover this when the Open button gets clicked. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

No; don't do that. You have to use shouldShowFilename: and implement -isValidFilename to validate the file when the user hits enter. Sorry -- there isn't any other way around it -- you can't have a folder disabled and still browseable with the current API. I'd recommend just accepting all folders, and if it is already in your list, then just let the user choose the duplicate, and handle it as a nop. OK, I will file an enhancement request because I think being able to disable a folder yet allow access to its contents can make sense in multiple cases. It would just require disabling the Open button.

Objet : How are we supposed to retrieve the generic bundle icon?
I need to get a NSImage of the generic bundle icon. (Mac OS X 10.4 or

I'm currently using this:
[[NSImage alloc] initWithContentsOfFile:@"/System/Library/
CoreServices/CoreTypes.bundle/Contents/Resources/KEXT.icns"]
because:
- NSFileTypeForHFSTypeCode('BNDL') does not work. It returns a
generic document icon.
- I haven't found an appropriate constant for
NSFileTypeForHFSTypeCode.

The question is not really whether you want to display a custom icon, but rather if the user wants one displayed. If they went to the trouble to change the icon, I imagine they really want it changed everywhere. In this case, no. Because it won't be visible at the end of the process.

Re: NSView positioning problems

So in IB, I placed a dummy custom view above the table view like this: - | custom| - | | | table view | | | |___| In the window controller -windowDidLoad method, I load the the OutputView which loads the OutputToolbarView (each have their own NSViewControllers). Now, I tried to make the replacement in the OutputView's controller awakeFromNib method but this puts the custom view on top of the table view, positioned at the origin specified for the custom view in the nib. That's because the replacement happens before the table view had the chance to resize itself according to the window's height (I think). If instead of replacing the custom view, I add it as a subview of the dummy custom view, the origin is correct but it doesn't fill the window's width. I've read the documentation about NSView and it's companion guide but it's a big chunk to swallow and I would like to see a simple example on where to put the code for replacing a view. In both cases, you can't just replace or insert a view and hope its frame will be correct. If you want to replace the custom view, you need to: 1) Get the frame of the custom view 2) Set this frame to be the one of your replacement view (better if done before adding the view) If you want to insert your view inside the custom view, you need to: 1) Get the bounds of the custom view 2) Set these bounds to be the frame of your view (better if done before adding the view). ___________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Best way to Change Window
On Nov 23, 2008, at 9:44 PM, Gordon Apple wrote: What is the best way to change to a different window? I have a main window nib with a lot of controllers in it. Currently the main view is in a scrolling window. I want to live-switch between that and a borderless (optionally full screen) window or a resizable (non-scrolling) window. I'm sure I could do this by duplicating or triplicating the nib, changing what is necessary, closing the window, change out the window controller in my document, open the new window. However, I don't like the duplicity of this approach and the need to synchronize future changes in similar nibs. Is there a better way? NSWindowController has "setWindow", but it also says: "This method releases the old window and any associated top-level objects in its nib file and assumes ownership of the new window. You should generally create a new window controller for a new window and release the old window controller instead of using this method." What are "associated top-level objects"? I don't want anything else to go away, although I would have to code a few wiring changes. When you needed to change between a brushed metal window and an Aqua window, a solution was to keep the content view of the current window, delete the window and create a new one with the appropriate theme and then replace the content view. In your case, it might be interesting to wonder if you want the control inside the window to look the same as non full-screen. If you take a look at iPhoto for instance, the look of the controls differs between fullscreen and standard mode. If you want the controls to look different, then maybe another nib is a solution. ___________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

[NSTableView] How should a grid be drawn?
I'm trying to draw a custom grid for a table view.

The problem is that when I scroll the tableview, some of the

I displayed the clipRect to check out which parts were being
refreshed. Still some of the lines are not drawn.

without better results.
What's wrong with the code?

When I click the italics check button. Nothing happens. How do I
suppose to make this wok?
How can I get the font the letter is using?
Look at the API doc and method prototype for -
convertFont:toHaveTrait:.
It returns a new font. You discard the return value, and don't
update any of your own state, so I'm not sure how you envisioned
this to work.
In the case where you want to remove the italic attribute, you
should be using -convertFont:toNotHaveTrait:.
Does one get the same results (Italic) when you use the
NSObliquenessAttributeName attribute? Or are these totally different?

[BUG?] - [NSLayoutManager usedRectForTextContainer:] returns incorrect value
Problem:
I'm seeing incorrect results when I try to get the height of a string
with a particular font and maximum width.
Context:
I'm running the code below. I have a single NSWindow with a checkbox
and a button. In the awakeFromNib method of the main controller, I
change the attribute of the checkbox string. In the compute: method,
I compute the height requested to display a string for a specific
font and maximum width.
If I run this code as is, I get 17.0 as the required height. That's
incorrect.
If I comment the awakeFromNib code, I get 34.0f as the required
height. That's correct.
Questions:
-

Re: [BUG?] - [NSLayoutManager usedRectForTextContainer:] returns incorrect value
On Mar 30, 2009, at 3:55 PM, Benjamin Stiglitz wrote: I'm running the code below. I have a single NSWindow with a checkbox and a button. In the awakeFromNib method of the main controller, I change the attribute of the checkbox string. In the compute: method, I compute the height requested to display a string for a specific font and maximum width. If I run this code as is, I get 17.0 as the required height. That's incorrect. If I comment the awakeFromNib code, I get 34.0f as the required height. That's correct. Is this the code exactly as it is in the app? e.g. compute: doesn't depend in any way on the values you set in -awakeFromNib? (I think this is your complaint, but I'm just verifying.) Yes. Not that this fixes your problem, but -[NSAttributedString boundingRectWithSize:options:] would probably be a bit easier for you to use. I tried it. It apparently does not work for multi-line text. I should probably add that additional tests show that the bug appears in Mac OS X 10.4.11 but not in Mac OS X 10.5.6. I also thought of a ugly workaround (strike the text with a bezier path instead of relying on the Cocoa Text Engine) but if there is a better solution, I'm still interested. _______ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

[NSOutlineView] _outlineCell and _trackingOutlineCell vs 64-bit
What's the official way to replace _outlineCell and
_trackingOutlineCell in Cocoa 64-bit?
I do this for 32-bit:
@implementation NSOutlineView (PrivateCells)
- (NSButtonCell *) outlineCell
{
return _outlineCell;
}
- (void) setOutlineCell:(NSButtonCell *) inButtonCell
{
if (_outlineCell!=inButtonCell)
{
[_outlineCell release];
_outlineCell=[inButtonCell retain];
}
}
- (NSButtonCell *) trackingOutlineCell
{
return _trackingOutlineCell;
}
- (void) setTrackingOutlineCell:(NSButtonCell *) inButtonCell
{
if (_trackingOutlineCell!=inButtonCell)
{
[_trackingOutlineCell release];
_trackingOutlineCell=[inButtonCell retain];
}
}
@end
But 64-bit is not happy with it at all.
---
I need to replace among other things the drawWithFrame:inView: method
to get a different rendering.
- (void)outlineView:(NSOutlineView *)outlineView
willDisplayOutlineCell:(id)cell forTableColumn:(NSTableColumn *)
tableColumn item:(id)item; is probably not what I'm looking for.

Note that what you are doing is not an official way to make things
work in 32-bit. It is strongly discouraged to access the ivars to
AppKit classes, and what you are doing may break in the future.
Well, the future is already there. You can't do for 64-bit
applications what you can do for 32-bit ones.
There is no way to replace the outlinecell
How could one then draw the disclosure triangle in white (and
correctly centered vertically) instead of black/dark gray (and
incorrectly centered)?
-- please log a bug requesting the ability to do so.
Will do.

Since you are aware in advance they might be a concern a little testing might give you a more definite answer and save some searching. (Fwiw, I eliminated the use in one place of an FSSpec since these seem to be getting more and more deprecated these days and I used FSPathMakeRefWithOptions (10.4+) in another place which looked like it would default resolve symlinks and these changes seemed to correct my own problem. No -1407 errors). My solution so far is to go with FSCopyObjectSync and make the FSRef conversion. I was hoping I would escape the conversion by using the path version. _______ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Calendar Store with non AddressBook participants?
Hello List, I am investigating the possibility to use icalserver to store medical appointments. This means either: - a physician (a user of the calendar) - a patient - a given day and time or - a resource (XRay material, etc...) - a patient - a given day and time Now, I have two problems: 1) It looks like I can only have participants which come from AddressBook. In my situation, participants are patients and come from a central database. They are identified by a GUUID. Obviously, I need to be able to search for all events for a given patient or add an event for a patient. Patients can't be users (I may have thousands of them). How would you do this from the Cocoa API? Or, if not possible from the Cocoa API, is this possible some other way through the CalDAV protocole? Maybe it is not as "participants" but as some additional info I should register a patient for an event? 2) It looks like I can't register through iCal an event with only a resource and a participant. I need a user. However, if a patient comes for an XRay, I know he will be using a given resource (the XRay machine), I know the patient, but the technician who will be in charge of handling the XRay is unknown (or at least, not important at that stage of setting up the appointment). I need to be able to know where there is still room with a resource for a given exam. And as for question 1, I need to be able to search for all future exams for a given patient or add an exam for a patient. Again, how can I do this through the Cocoa API? Or, if not possible, through the CalDAV protocole.

Loading mechanism with NSAtomicStore
Hello List, As I understand, when using NSAtomicStore, there is only a "load" method to load the data. It looks like it is an "all or nothing" operation. However, if I want to load data from a server through some kind of HTTP/XML/Whatever method and only receive a subset of data. How would I implement this? For example, I want to retrieve a list of patients from a hospital system. Obviously, I am not going to load all the patients of the hospital! Now, I can imagine having some king of global variable read by the "load" method I implement to load only the list of patients I need. But then, how is the faulting handled? A patient will refer to a list of medications, a list of visits, etc... My load method, again, can't deeply fetch all the objects potentially needed because I would end up with all the objects in memory. So I suspect, if a fault is triggered on an object in memory and the object is not (yet) in the local cache, I need my NSAtomicStore (subclass) to be notified to read from my distant store (HTTP/XML...) the missing object(s). Is this possible currently? Any thoughts or solutions for this problem are welcome!

A separate thread is spawned which updates the model - consequently driving UI updates based on KVO notifications.

Re: Alerts in Xcode 11
I'm by no means an expert but if I understand what you're trying to do, I think
the approach I would take is to make an extension on UIViewController:
extension UIViewController {
func notificationAlert(_ msg1: String, _ msg2: String) {
// create the UIAlertAlertController
// and then do as David Duncan said and do:
self.present(, animated: completion: …)

}
Now all your UIViewController subclasses can call that method (and because it's
a method, they have access to self which is a subclass of UIViewController).

Re: Thoughts on Cocoa
There’s a (short, I think) chapter missing from this story. I attended a public (technical) talk in Town Hall (I think it’s called) at Apple shortly before or after I went to work there. It would have been around 2000-2001. The speaker’s message was that the future of the desktop was Java. A pretty big surprise and unwelcome news for those of us who saw Apple as the future of Objective-C and the NeXTStep lineage rather than the other way around. As the talk went on, it came out that the speaker was the manager of the compiler group responsible for Java and Objective-C — and had been going back to early NeXT days. So one had to conclude that he was committed to the course he described. People tried to ask about Objective-C (vs. Java) and he said that Objective-C was done, he clearly didn’t want to talk about that. This before the public release of Mac OS X 10.0. Another effort that sank in the deep blue sea. I think one has to assume that technology strategy at Apple is less disciplined by the business side than at companies like IBM, Microsoft, Intel, Oracle, etc. And within Apple, there is a certain amount of chaos within Engineering that gets exposed from time to time. I think they might feel that’s a good thing. If you’re thinking like a business person, you should accept this as a given and make your decisions accordingly. If you’re thinking like a person who likes the technology, you may or may not reach the same conclusions. But I don’t think you’re going to change the way Apple does things. Me, I still don’t understand why, given the long history of support at Apple/NeXT for C++ and the maturity of the compilers available, there is any need for Swift. But there it is. Or, there they are. Perhaps this is the way the younger generation overtthrows the older? Or not, but I’m pretty sure there is no compelling business argument for it.

Re: Sharing code between screensaver and regular app
Hi, You need to create a project with the right template to start with. In XCode: File/New Project - Select MacOS and then “App” (from the New Project Dialog). On XCode 11.0 and MacOS 10.14.6, this results in a new project Setup with a view controller. There are a number of ways to share code between Apps. I usually have a folder structure like this: CommonSource ScreenSaver StandaloneApp Put the code that is common between the two into “CommonSource” and the App Specific Stuff into either “ScreenSaver” or “StandaloneApp”. Then add the common files to both projects and compile as normal.

Re: Sharing code between screensaver and regular app
Hi, All I can think of that this behaviour has changed on your version of MacOS/XCode. You can do the same thing as the template by manually adding the files, e.g copy your “ViewController” file, rename it and then add it to the new project. You will need to make sure that the Storyboard/Nibs are the same too. Ether add the elements needed yourself or copy the existing storyboard/nib(s) rename and add to the new project.

Re: Sharing NIB/XIB between different apps?
Hi, If you decide to use multiple targets then it’s still better to have a folder for common files and one for each target, both targets include the Common folder but you only include the folders appropriate for each Target. By “include” I mean you check/uncheck the targets that the file builds against, so Common files are checked for to project and the specific files only for the target they belong to. You can also use a “Workspace”, which is what I tend to do, you then add projects to the work-project (which can have sub-projects), it’s all a bit complicated to be honest, but the docs are pretty good. The best way to find out more, is to find a Sample project that uses a Workspace and go from there.
