Save Images Imported/Dropped To IKImageBrowser
i've been using Apple's ImageBrowser sample code to further understand
the image browser:
http://developer.apple.com/samplecode/ImageBrowser/listing2.html
i'm trying to make the image browser save the images that it displays
by copying any dragged image into it's own folder, and have the image
browser automatically display the contents of that folder whenever the
app launches.
for copying a dragged file into a designated folder (which i would use
to load images on init) i've tried adding the following to the
performDragOperation method, but it doesn't work for me (the desktop
here is just for testing):
if (data)
{
NSString *newFolder = @~/Desktop/;
newFolder = [newFolder stringByExpandingTildeInPath];
[data writeToFile: newFolder atomically:YES];
next i (think) i would set user defaults on deleting and reordering of
the images, so that the designated folder would also be in sync with
what is actually displayed in the image browser. and finally, i would
add code to the initialize method that would populate the image
browser with the images that are inside the designated folder (here,
the desktop).
the problem is i'm lost... hah... also, i'm not familiar with
datasources, so i'm not 100% sure i know what it actually is... i'm
assuming the datasource is the URL of the file that is pasted on the
pasteboard during a drag, but that seems temporary, so how can i set
up a permanent datasource??
if anyone can direct me to some sample code that does exactly (or
close to) this, that would be amazing.

Re: Creating NSDecimal
looking at the documentation I think you need to start with an NSDecimalNumber then use one of the member functions to convert it to an NSDecimal, do the things you want to do on it, and convert it back again. Remember also that NSDecimal is really just a structure, not an object, so when you declare it you'd normally do it on the stack, not as a pointer. so I think I'd try something like NSDecimal decinum = [ [ NSDecimalNumber decimalNumberWithMantissa:1675 exponent:-2 isNegative:NO ] decimalValue ]; I suppose you could try to make one directly by doing NSDecimal myDec; then setting myDec._exponent and myDec._mantissa[], if you can figure out how it stores its mantissa but that seems to be more work and they are private so you'd be opening yourself up to apple changing the whole thing later.

If you're willing to force someone to look at the image, you can get away with a really fast hack; use coreimage to do a Difference Blend Mode merge between the two images. If they are identical, the resulting image will be black. Anywhere the images are different, you'll get colors. As others have mentioned, this trick will not work if the images are different sizes, misaligned, rotated, different resolutions, etc. It is similar to what Beyond Compare does when it compares images (although IIRC it uses XOR on each pixel, not difference), and is only really good for quickly checking what changed between two images that are already fairly similar (which is handy if you want to know what modifications your artist did to the resources you have in your application).

Re: Delegation across thread
Thanks a lot for your very clear explanation Michael. Looks like performSelectorOnMainThread: will be the way to go. Thanks again, Andre Masse On Oct 31, 2008, at 00:41, Michael Ash wrote: It's important to remember that delegate is just a design pattern, not a language feature. A delegate is just a defined set of messages that you send to an object in certain situations. When it comes to threads, they behave just like any other messages, because they are just regular messages. So what happens when you send a delegate message on a secondary thread? Same thing as when you send any other message: the corresponding method gets invoked synchronously on the same thread. (I.e. you call it directly.) This can be bad. If you're going to do this then your delegate needs to be prepared to receive delegate messages on secondary threads, and that can sometimes be annoying. Sometimes it's entirely reasonable. It really depends on your situation. If your situation is such that it's unreasonable, the solution is easy: just use performSelectorOnMainThread: to ship the delegate message back to the main thread where it can be invoked in a better place. If you want to invoke it on some thread other than the main thread then Cocoa provides a fair number of inter-thread communication techniques that you can use. Ignore the fact that this is a delegate and just see how and where you want to send your message. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

The only way I could think of is comparing every pixel, but this seems like it would take a long time, and even so I have no idea how to go about doing that. It's non-trivial. Comparing each pixel doesn't really work. You could have two identical images but if one was shifted by just 1 pixel, you'd have almost no match even though to the eye they'd look the same. You can compare images for equality this way, but not similarity (i.e. if they are absolutely identical in every way you can tell, but the smallest difference means no match at all). Researchers have been looking into this sort of thing for years. There are ways to do it, but it requires some pretty heavy lifting in terms of breaking down an image into features then finding whether those same features can be found in the second image, regardless of how those features might have been transformed in size, position or angle. You can then come up with a figure for the number of feature matches and how these are different, and so arrive at a figure for the overall similarity of the two images. So, it can be done but you'll need to look at some serious academic papers to get a flavour for what's involved - it's almost verging on AI.

Yes, but is older than the OpenStep specification (1993) that is the true ancestor of Cocoa. NeXTSTEP is the true ancestor of Cocoa. The NeXTSTEP APIs were quite similar to OpenStep (of which, of course, Cocoa evolved out of). There is relevance to Cocoa-dev here, assuming that an understanding of history helps you. The shift from NeXTSTEP to OpenStep was really focused on a several of areas of change. - The memory management model moved from a classic straight alloc / free model -- literally, objects implemented -free and you called that directly to tear down and deallocate the object -- to a reference counted model using -retain/-release/-autorelease. - Much of what had been straight C APIs were replaced with classes and methods on said classes. User Defaults functions moved to NSUserDefaults, for example. File management, archiving, and a number of other fundamental subsystems were moved to Objective-C. - NSString was added, along with NSDate and NSNumber, and the NEXTSTEP collection classes (List and HashTable) were retired in favor of NSDictionary, NSArray, and NSSet. List and HashTable supported non- ObjC types, but this greatly limited their capabilities. The new collection classes -- what you have today -- were pure object contains and, thus, operations like archiving, KVC, etc... were enabled. - In general, much of what had been code that every developer seemingly needed to write over and over were captured as general purpose, reusable, APIs. When OpenStep was released, it contained a porting toolkit that would run through an application's source and convert it to use the new APIs. Trivia: Andrew Stone's Create -- www.stone.com -- is the only Cocoa application (that I'm aware of) that has run on every single release of Mac OS X, OpenStep, NeXTSTEP, or derivatives (including Sun's NEO) as well as on every processor for which support shipped -- m68k, i386/ mach, i386/windows, SPARC/mach, SPARC/solaris, PA-RISC, PPC, and maybe some I'm forgetting. (Before joining Apple, one of my last contracts involved porting a 750,000 line Objective-C++ application from NS 3.3 to Mac OS X 10.2 [Jaguar]. It was actually quite a bit of fun and required effectively porting to OpenStep 4.2, then Rhapsody DR1, then Mac OS X Beta, then -- finally -- Mac OS X 10.2. By doing this, I was able to port the rather complex NIBs, including custom palette support, from NS 3.3 to MOSX 10.2, taking advantage of the compatibility archive support in AppKit/IB at each stop to preserve the NIBs.

Re: Compare images in Cocoa

The only way I could think of is comparing every pixel, but this seems like it would take a long time, and even so I have no idea how to go about doing that. This very much depends on the type of differences you are expecting. The first thing to note is that you can't do this without accessing every pixel in both images, but there are library functions for applying functions to 2-d arrays of pixels in CoreImage and deeper down in the veclib and vImage frameworks. If you are just expecting the images to be largely the same but some pixels to be different then simply using CoreImage to produce a bitmap based on the pixel differences is pretty easy and very fast. If you expect images to be the same scale but differ in (a) some pixels' values, (b) brightness and/or contrast or (c) parts of the image are translated, then in general the first thing to do apply a convolution function with the two images as inputs. The mathematics are sticky but OS X includes library functions to do it for you. Try looking on Google for terms like image convolution, motion detection, motion compensation, etc. Basically you'll get an output from the convolution where the strength of the spike in the middle of the output represents how similar the parts of the image that have not moved are to each other. Where parts of the image have been translated from one image to the other you will get an output spike offset from the centre by the movement vector, the size of spike representing the size of the area that moved. If you expect that between your two images some parts will be scaled as well as translated then the whole problem gets much more complex, so you might want to avoid these cases :-) Cheers, Nicko ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

You don't say what you want this number for. Are you trying to tell if two images of faces are of the same person? Two images of buildings are of the same building? Two images have similar colors in them? FWIW, iterating over all the pixels in an image and doing some kind of simple math on the pixel values will not be very time-consuming. There are lots of Photoshop filters that do this and are very fast. One thought that comes to mind is to calculate the histogram for the two images and compare them.

How to read proxy username and password?
Hi all, I've got an application which uses a third party command line tool to download some files from the web. Unfortunately, the command line tool won't work with a proxy server unless the proxy settings are written in clear text (ugly but nothing I can do about that) in a config file. The config file itself is read/write only by root, so it's not *quite* as hideous as it could be ;-) Anyway, writing to the config file isn't a problem. My question is how can I read the System proxy username and password settings from within my application in order to be able to write them to the file? I've searched through the mailing list archives and had a look at the SystemConfiguration Framework API but still can't quite find what I'm looking for. The closest thing I can see is SCDynamicStoreCopyProxies but that only returns the following keys in the dictionary: kSCPropNetProxiesExceptionsList kSCPropNetProxiesHTTPEnable kSCPropNetProxiesHTTPProxy kSCPropNetProxiesHTTPPort kSCPropNetProxiesHTTPSEnable kSCPropNetProxiesHTTPSProxy kSCPropNetProxiesHTTPSPort kSCPropNetProxiesFTPEnable kSCPropNetProxiesFTPProxy kSCPropNetProxiesFTPPort kSCPropNetProxiesFTPPassive none of which is what I'm looking for.

Just for grins, I changed my call to update the reflection to use performSelector:withObject:afterDelay: instead, and while that does help the paging issue, it completely breaks dragging the knob; doing that now, it doesn't update at all until I release the mouse to end the drag.

Your caveat (problem with other pdf readers) was also well taken! Ricky, thank you for your trenchant analysis and commentary. The reification of your suggested approach, by mentioning the TextEdit example, was way helpful! Michael, you've identified additional (and compelling) approaches that I'd have never quantified on my own! They bear looking into; part of my continuing Cocoa education :-) Dave, you know a lot about the PDF format! Thanks for quantifing a PDF compatible way to append metadata to a PDF! Jeff, you also know a lot about the PDF format! Thanks for clarifying another PDF compatible way to append metadata to a PDF! Marcel, thanks for your reply! My conclusion is that The Cocoa Way would be to use NSFileWrappers. (Not to deprecate the suggested PDF approaches – there's nothing wrong with them.) I've looked at using NSFileWrappers, but still have some questions. My plan is to take them to NSCoder Night (in Campbell) and flesh out the recipe, part of my ongoing Cocoa education :-) As an aside, I want to strongly recommend Eric Buck's Cocoa Design Patterns which led me toward the NSFileWrapper approach in the first place!

Re: Simple Flipbook Animation?
Look at overriding the layer transition. You can use a page curl filter, if that's your desired effect, to transition changes to the layer's content property. - Create a CATransition object. - Create a CIFilter that implements a page curl (Check out Apple's Core Image Filters docs and sample code). - Set the transition object's filter parameter to your CIFilter - Add the transtion to the layer actions for the key content Then, whenever you set your layer's content parameter to the next image, it will use that transition instead of the default fade. This of course assumes that you know you need to convert your NSImages to CGImageRefs first since the content property cannot be set with an NSImage.

I have undo/redo working throughout my program but I seem to remember earlier that upon opening a document and immediately after beginning to change the state of a text field that the document dirty status would be changed, before an actual undo was registered on the undo stack. (As a result of -objectDidBeginEditing:?) Somehow I've disabled this behavior and for the life of me I can't determine what I've done wrong or how to get that behavior back. Does anyone have any clues? After a lot of stepping through the debugger I've seen that in new NSDocument based projects that edits happening through a controller send an -objectDidBeginEditing: to the NSDocument object via [NSValueBinder _startChanging]. In my project though, for some reason I have yet to uncover, NSValueBinder's _startChanging method checks to see if my NSWindowController subclass responds to objectDidBeginEditing: when that returns NO it stops looking and never checks my document subclass. If I implement objectDidBeginEditing and objectDidEndEditing: and have them forward those messages on to my document the document dirty state is represented correctly as it is in a new project. So, this suggests that somehow I've mucked up the responder chain between my window controller and my document but I don't see anywhere where I might have done something like that. To be honest though, I'm not sure that I'd know how to without reading up a lot more on the responder chain anyway. Before I read up on the responder chain to see what I might have done, does anyone know if I'm on the right track here?

Jeshua, disclaimer I have no idea what you are actually doing in your code, so any advice i give below is pure speculation/disclaimer Let's say you have an array of NSImages and an NSImageView to display them in. I would create the animation, set a collection of progress marks, and use the delegate method -animation:didReachProgressMark: to set the NSImageView to the appropriate NSImage for the progress mark. if you want to use CALayers, you'll need to convert your NSImages to CGImageRefs, set up your animation, and then use the delegate method to set the content property of the target layer. hope that helps, regards, douglas On Oct 31, 2008, at 1:48 PM, Jeshua Lacock wrote: On Oct 31, 2008, at 11:07 AM, douglas welton wrote: Did you take a look at using the NSAnimation class?

I have a subclass of NSTableView that I use that allows the use of the return key during a field edit to move to the next row and begin editing. This works fine _unless_ the field I'm editing happens to be one that NSArrayController is observing and thus causes a rearrangeObjects call. When this happens my table view loses focus and its' textDidEndEditing: method is never called. This happens even if the field in question is no longer the primary sort criteria. Turning off the auto rearrange content support of NSArrayController fixes it and calls my subclasses textDidEndEditing: method. Has anyone else seen this and found a way to keep the focus on the table view after its' contents are rearranged like this?

Number in NSString to int.
Hi there,
I'm trying to process a MAC Address into Hex so I was going to do
something like.
NSArray *macArray=[[NSArray alloc] init];
macArray=[mac componentsSeparatedByString:@:];
for (int i=0; i [macArray count] ; i++)
{
//somehow need to get an int called dec from the number in the
NSString then...
NSString *hex=stringWithFormat:@%x,dec;
[macArray[i] autorelease];
macArray[i]=hex;
}
My main question is how to get an int from an NSString, but also, if
you could have a look at the rest of the contents of the for loop I'd
be grateful as I'm sure I'm making a pigs ear of the memory management
there. Sort of had a feeling that it would be autorelease as I thought
that the substrings in the array would be the responsibility of the
array rather than me, but other than that I was a bit boggled.
Thank you all.
Adam

Padding Zeros...
I'm having an interesting problem... I'm trying to format a number with padding zeros but I can't figure out how to do it in this particular situation. I know I can use a formatted string with something like [stringWithFormat:@%03d, 5], which would result in 005 but the problem in this particular case is that the number of padding zeros (3 in my example) is a variable defined by the user... (let's say it resides in an int variable named int paddingZeros) Is there an easy way I can pad a number with a variable amount of zeros?

The comboBoxWillDismiss may come before or after the text change, depending on whether the selection is made with the return key or the mouse.

Tracking changes to NSTableView datasource
Hi, I have a datasource for an NSTableView which is a NSMutableArray (call it mainArray for the moment) and I'm not sure which way is better to manage add, update and delete rows. I can use either one array for each of those cases or add a field to the mainArray (like 1 for new, 2 for update) and only one array for the records to delete (I'm using a back-end database). The first problem with the former is if (when) the user add a row and modify it later on (but before any updates to the back-end are done) I will need to check if its a new row (by quering the newRows array) and then not add it to the update array if it is. Not counting keeping both array content in sync... With the later, only checking the field will tell me if its a new row or not. At this point, I prefer the second method and can't see too many problems with it... Now, how you guys handle these kind of things? Any ideas, suggestions?

You could try using the dependency mechanism in addition to setting maxConcurrentOperations to 1. Keep track of the last NSOperation in your for loop and assign in as you go. If that fixes it, it could be a race in maxConcurrentOperations. This is all highly speculative. Thanks for the suggestion. I tried it out and it still crashes with that same exception. I even tried it without setting the maxConcurrentOperations and it still crashed. When I tried it in the case where the operations get enqueued in a separate thread instead of from the operation method, then it still crashed but took a long time (5-10 minutes, didn't count exactly) to do so. So it would seem that this helps somehow but not quite enough. This last case is particularly scary to me. I'm not doing anything that NSOperationQueue isn't explicitly set up for. I'm just posting NSOperations to queues that have been created and are sitting in memory. I'm not fiddling with the maxConcurrentOperations, I'm not doing anything weird like enqueueing a new operation from the middle of an existing one, I'm just spawning some threads which post operations to queues and let them run. And it *still* crashes. I hate to make this sort of sweeping pronouncement because it seems like a great way to end up looking like a fool, but at this point I can only conclude that NSOperationQueue is fundamentally broken and should not be used until this problem is fixed.

Localization of Cocoa-Xib for a Newbie
Hi, I want to try Localization of a XIB, but I have problems: I have the following Equipment: - MacOS 10.5.5 - MacOS is runnig in German - System-Preference Languages are (in order): German, English,... - XCode 3.1.1 I make the following steps: 1. I Make a new Cocoa-Application project 2. I open the English-MainMenue.xib (doubleclick in Xcode starts Interfacebuilder) and put a label my English text into the window. Save it, Close IB. 3. In XCode I use Get Info of the English-MainMenue.xib and add Localization for German. 4. I open the English-MainMenue.xib (doubleclick in Xcode starts Interfacebuilder). I use Open Localization to get to the German- MainMenue.xib. Here I change the label to my German text. Save it. Close IB. 5. Build and run my application. Starting my App I get the label my English text, but my prefered language is German!! Additional steps. 6. I create in the group Resources a File Localizable.strings. I write into it: myHello = Englisch Hello; 7. In XCode I use Get Info of the Localizable.strings , use make Localizeable and add Localization for German. 8. I change the content of the german Localizable.string to myHello = German Hallo; 9. I put the following line into my main.m: NSLog(NSLocalizedString(@myHello,nil)); 10 I build and run my application again. The results are: - in my application window there is still my English text - but in the console window I found German Hallo So it seems clear to me that my created application knows that it should use the german localization, but it uses the wrong localization of the XIB files.

Re: Localization of Cocoa-Xib for a Newbie

Hello Ken, Thank you for REALLY GREAT hint: The english MainMenue.xib has the File Type file.xib but the localized version for german is sourcecode.xib. I changed it to file.xib , rebuilt the app and it runs as expected.

In the file list, disclose the .xib to see both localizations. Get Info on the English localization and the German localization and compare. Make sure that both indicate File Type: file.xib.

Re: Tracking changes to NSTableView datasource

I need to identify what the user did to be able to reflect theses changes back to the database.

Re: Finder like wrapping + truncation

My first question is: is there any method around for making a string to line wrap, and to truncate the second line if it is too long (like on the right hand image in the screenshot). Is this supported in an API? It's supported as of 10.5. See NSStringDrawingTruncatesLastVisibleLine in NSStringDrawing.h, along with appropriate NSParagraphStyle options. The second questions is: can the NSAttributedString render the background for the text like the ones on the screenshots or is it something I have to draw myself?

Re: Finder like wrapping + truncation
Thanks Adam, works grate! There is only one little flaw that it always truncates the tail and I don't see a way to change this. On Nov 1, 2008, at 2:50 AM, Adam R.

Did you try setting NSLineBreakByTruncatingMiddle on your NSParagraphStyle? I don't recall trying that with NSStringDrawingTruncatesLastVisibleLine myself, but it should work. -- Adam smime.p7s Description: S/MIME cryptographic signature ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Gradient panel
Is there an easy way to instantiate a Cocoa panel with a gradient background? Are there any code samples? Is NSGradient the key? Any examples of how you hook this in with a panel or window?

Remember that drawing in Cocoa takes place in a view; from that perspective, Cocoa panel with a gradient background isn't really a well-formed concept, because it's assuming the panel draws rather than its content view. So just create your own custom subclass of NSView in which you override -drawRect: to render an NSGradient, and use an instance of it as your window/panel's content view. Or even just put it within your window/panel's content view, covering 100% of its area, with its springs and struts set appropriately. -- Chris ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
