Re: machine with null serial number?
Indeed it is almost always when a mac has had the logic board replaced/repaired. It does occur. Sometimes even a new batch of macs may ship without serial numbers or even with a system profiler depicting the wrong system. It's pretty rare, but does happen, so it may not be the best thing to tie in to for a software licensing scheme. You'd be much better off being a bit more generous or at least trusting with your licensing. Apple is certainly pretty fair about putting most of their software on a good faith licensing scheme. Heck, they're not even to stringent about academic pricing! You might consider using something more reliable for licensing like simply hashing the customer's name and purchase date or other info. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: machine with null serial number?
Indeed, on repair, the computer should have the old serial number. This is why it is also located on the case, exact location depends on the model. The only time there should ever be a new serial number is when a Mac is outright replaced. Definitely, it is a bad idea to depend on the serial number at all for software. MAC addresses are not entirely difficult to spoof either. The best case is to either have users register the product, the Microsoft way, or simply accept that a certain level of piracy is inevitable with desirable software. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Custom Buttons - Tutorial/Examples...
Does anybody know a tutorial or example on creating custom buttons in Cocoa? I can certainly set an image in IB or programmatically, but how can I determine the actual hitmask? Or even set the mouseOver type of event for something like a rollover ? I know I'm talking about stepping on Apple's HIG, but it is something I'd like to know how to do without delving into CG or CA right now. I've been toying with it a bit today, and I can certainly set the images, but on mouse down, the background changes to the image with a darkened state inside of a white rectangle... surely I'm missing something stupidly obvious...?

After Unarchive Object Exists, After First GUI Action, gone...
I apologize for the beginner nature of this, I must be missing
something obvious, but I cannot see it.
Archiving works fine. The data is there. I've inserted NSLogs
everywhere to no avail.
When the file is opened (unarchived) the log showed me the first
object in my array has the correct data.
But the data for the first object in the array (all are NSStrings)
never appears in the textView. Something is erasing or emptying the
contents of this string somewhere between unarchiving and display.
The other array objects are unaffected.
Here's my implementation file (most of it)

In the method - (void)windowControllerDidLoadNib:(NSWindowController *) aController I added this: [textView setString:[[stickitNotes objectAtIndex:0] noteBody]]; A few general notes: 1. You should never have to call setNeedsDisplay: on anything except self (in NSView subclasses). A properly written view will do that on its own when its contents change. 2. There's a lot of duplication in your code. You should probably factor out some common code into a new method (updateCurrentNotes? setNoteIndex?). Alternatively, you may want to take a look at Cocoa Bindings - in particular, NSArrayController - which should be able to do a lot of this work for you. Thanks Andrew, yep, that's where I picked up setNeedsDisplay, so I was just trying it to see if I was missing something. As for the duplication, yeah, I am aware of it, but refactoring can come in after functionality for this. I've worked with Ruby a lot so I'm willing to write rough drafts and fix it later. I agree and was thinking that Bindings would possibly be the way to go for this. I actually just lifted large bits of the thing from the Hillegass book's RaiseMan application, which is a terrible app that introduces a lot of different elements of Cocoa at once. the trickiest part of bindings seems to me to be the key paths. Getting those right (and some of the settings in the inspector palette in IB) is a bit mysterious. Do bindings rely mainly on NSDictionary or do they work well with NSArray too? In this case, I'm building a note app to replace stickies for a very specific workflow. I just need it to be fast and stable with a small footprint. Things could be refactored to use dictionaries for more meta data, and probably will be, but NSArray seems to be the fastest lookup and is already sequential. But for now I'm just trying to wrap my head around enough of the Cocoa basics. In particular, after Ruby (not even Rails necessarily) I feel quite comfortable with Objective C and Cocoa, but sometimes I feel like methods I should have are not there, or I can't guess the name of them. It's probably me thinking Ruby, but I often feel like I'm just missing methods for NSArray... ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: [Ann] DMG Canvas
Is there a way using this tool or even programmatically, to have disk images mount without having the collapsed toolbar?

There is definitely a big gulf of knowledge that all of us should be working to educate users about, albeit in subtle ways. We should all be making subtle efforts to convince users that they want to and need to learn more.

Re: How is "Apple + Ctrl + D" implemented?
Graham, Thanks for your reply! But how can I "find the range of the word" given the glyph index? I just can not find an API doing so. So I don't think this is the underlying implementation. Any comments from others? The range of the word is up to you to find and depends on the language. If it is any common language from Europe, your job is a lot easier. You mainly need to work with whitespace and punctuation. If you're working with Japanese, you'll need to learn of lot of complex tricks to identify the range of words... As for the implementation of the keyboard shortcut, you'll find it appears in Sys Prefs > Keyboard & Mouse > Keyboard Shortcuts , Dictionary. That being the case, it is possible to turn off the existing shortcut. It may not be feasible or reliable to do so programmatically. Apple is free to set these shortcuts to anything at any time and at any level. You may need to instruct your users on how to change the keyboard shortcut(s). The hard part is finding something available. Some things are taken up system wide, some are taken up on within apps. The only way to wrest control of these is with an input manager, but that may not be worth the trouble. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Save as and Open conditional code samples? tutorials?
Does anybody have any code samples or tutorials on opening/saving documents with conditional handling for different file types? Conceptually, handling the content is not a problem. The thing I'm not sure about is how to hook up a document-based app to handle additional file types but with the preferred native document type. My app's documents are little more than an array of strings, where each string is a sub document. The thing I want to do is export all as a single text file or as individual text files, and likewise import a text file with simple string symbols as separators (basically like a CSV file). Handling the text and doing things with it is easy.

Re: Cocoa bindings and reluctance to use NSPopupButon
Johnny Lundy had a difficult time using NSPopupButon along with bindings. The struggles are archived via www.cocoabuilder.com for posterity. Mr. Lundy recently wrote "...I am still very very hesitant to put another NSPopUpButton on my interface, because of the complete absence of guidance on how to implement the thing, and the many days it took to get a single one working, and even now I have no idea why it works..." Having just now re-read Mr. Lundy's questions and follow-up, I don't think he had any problem with NSPopupButton at all. That makes sense because NSPopupButton is not particularly difficult to use. I think Mr. Lundy's struggles were all with "bindings." Had I been inclined to participate in the threads at the time, I would have said the following: 1) Bindings are an ADVANCED technique that was recently introduced and not yet completely documented. If someone tries to use bindings in a situation where he/she doesn't already know how to write the application without bindings, it is a mistake to use bindings. 2) Bindings exist to _reduce_ the amount of Controller code needed when the Model View Controller pattern is used. Bindings don't eliminate controller code and can't handle all Controller responsibilities. 3) Bindings appear to be magic, but they are in fact just an abstraction that enables reuse in place of commonly re-written controller code. 4) Bindings ARE NOT A REPLACEMENT FOR ALL CONTROLLER CODE, and bindings are often not the best technique to use. Mr. Lundy would have been better off writing his controller code explicitly and using the established outlet, target and action patterns instead of bindings. Not only would he have achieved complete control over all aspects of his application's behavior, he would have gained insight into how, and and why bindings work or not. I find that I hardly ever use bindings in my own applications. I am more comfortable doing things the good old fashion way in part because I often want very fine control over application behavior. I blame Mr. Lundy's specific struggles on misguided insistence on using the wrong tool for the job. I counsel Cocoa newbies to just forget about the Bindings inspector in Interface Builder and pretend they don't exist. Thank you Erik! That's what I had concluded at one point, and then felt pushed back towards. People often said, "you should just use bindings", but I felt I did need to first understand how it works without bindings... With tableViews and treeViews, I can totally see where bindings would simplify a lot of things, but still... the bindings docs are still tough reading. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Hillegass Book 3rd ed. ScreenShots differ?
Maybe this should go to the XCode list, but I know there was much talk about the 3rd edition of "the" book here. Anyway, I'm sitting down with my new Mac, and the 3rd ed. of the Hillegass book, and the thing I notice is that when starting a New Project, the window for selecting an XCode template still appears basically the same as in XCode 2.x, but in the Hillagass book the screenshot shows something more graphical, more in line with iWork template selection screens... (yes it IS XCode 3, not 2.5) So is that screenshot from the prerelease version or something? Or is there a way to turn it on?

Transparent content view of NSWindow clicks through
I'm toying with using a transparent content view of an NSWindow.

Turns out, I forgot to put anything in the Entity Name field in the Attributes Inspector for the NSArrayController for Topics. The field was blank, but should have been "Topic".Wow. What a horrible little bug to track down. I hope the workflow of Core Data is much cleaner in Interface Builder 3 (when my MacBook returns from repairs...) It certainly seems to me that in XCode 2.x, the Interface Builder workflow for Core Data is not the best it could be for Core Data. The Data Modeler is pretty nice. I found myself thinking Ruby on Rails' ActiveRecord needs something that visual. Unfortunately for Core Data, all of the various settings (that need to be correct and correspond to each other) are spread out and within so many different views of the Inspector palette, it can be hard to make sure you have everything correct. Maybe it comes with experience, but something tells me there could be a more concise way to view and work with these things in Core Data. Ruby on Rails' ActiveRecord sometimes suffers a similar problem. The code feels a bit like spaghetti code (think old BASIC from the 80's with goto statements). I do believe the programmer should and could easily be alerted that there is no Entity Name set! Obviously, the Entity Name is crucial to making Core Data controllers work.

NSScrollView responding to changes in alpha
Interestingly, NSScrollView in an NSPanel HUD window can have its background color set with alpha and transparency is easy to achieve. Inside a normal NSPanel or window, the backing of the contentView rect seems to be all that will mix with the background color alpha. Ideally, I'd like this same behavior with a non-HUD panel or window. Also, HUD panels seem to want to remain in front. Does anybody know a quick way to disable that? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Loading a different interface
In my application, I would like to give my users the option to choose various interface styles. I've laid out my interface using a standard NSPanel as well as the HUD version. Both are suitable, but some users will prefer one over the other, of course. Currently, I have both windows in one NIB. Is there a way to choose which window is loaded from the NIB? Is it possible to do this without losing the data in the document? (it is document based) Would it be better/more practical to factor these into two different NIBs? Also, on the same subject, is there a way to force a HUD window to display the zoom and minimize buttons? Lastly, I have envisioned the possibility of simply having an info button like in Dashboard widgets and providing functionality similar to Dashboard widgets for flipping the window around to adjust the settings of the window. Does anybody already know of some open source example doing something similar? cheers, John Joyce ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Refactor your interface into two nibs, where each nib is owned by an NSWindowController rather than by an NSDocument subclass. Then you can override -[NSDocument makeWindowControllers] in your NSDocument subclass to instantiate whichever NSWindowController is initially appropriate, and when you want to "switch" interface styles you can use -[NSDocument addWindowController:] and - [NSDocument removeWindowController:] to get rid of the old and add the new. -- Chris Thanks Chris, this leads me pretty much where I suspected I would end up going. One other thing, does this mean I need to subclass NSWindowController as well? Or simply create instances of the default NSWindowController and feed them as necessary? Either way, from my NSDocument subclass (MyDocument as usual) I should be able to instantiate more than one window controller, and then load my respective NIBs by [NSDocument addWindowController:aWindowController] Will adding a window controller release / close the current window? Clearly, I'm heading down the path of becoming more acquainted with NSWindowController, which seems inevitable if one wishes to do interesting things with the interface. I figured as much. Perhaps this means I'm beginning to grasp more of the AppKit. It does look like it will take a little experimentation to get precisely what I want, but that's cool, it means I will be more aware of how to do interesting things! -- John Joyce ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Binding NSArrayController's objects to an NSTextView
I'm trying to learn to use bindings. Right now, I'm adapting the venerable RaiseMan example in the 3rd edition of Mr. Hillegass' book. Of course, in RaiseMan, the NSArrayController and the corresponding array and its objects are bound to a table view. What I'm trying to do is bind to an NSTextView that is the backing of an NSScrollView. Each object in my array has its own @properties, of course. Each object has an NSString in it, which I want to use as the text for the TextView. Just to see what happens, in my nib I've got these bound both to a table view as well as a text view. The table view behaves as you would expect. The text view gives really bizarre results. It resembles an NSLog description of an array. Editing directly in it, gives identical changes to all objects in the array. Sometimes the results of editing directly in the text view are just strange! Any tips on how this should be done? Am I possibly missing something in my key path or missing some other intermediary thing? The code is identical to the 3rd edition RaiseMan, but with no numeric values, only working with strings. (thus the table view has only one column and headings are not important.) ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I don't believe specifically for your case (ie, an NSPopUpButton), but this list's archives contain various (attempts at) textual explanations. I keep getting "cannot perform operation without a managed object context" This would seem to imply that I should be using CoreData. In Interface Builder, inspect the Attributes of your array controller. You'll see a mode control that lets you specify whether to use a Class or an Entity. You most likely have Entity selected (which requires a MOC, as the error says). Select "Class" instead. Is CoreData really the way to go when trying to do much more with bindings ? No. The two interoperate very well by design but are not mutually inclusive. -- I.S. Well, I already checked that, it is Class, not Entity. I'm already aware that Entity is used with Core Data models. Oh, well, I'll figure something out. I always have a terrible time with NSPopupButton in any context. NSArrayController provides some nifty methods, selectNext: and selectPrevious: but I need a select: that chooses a specific item from the array. Either by index or what have you. I did find setSelectionIndex: in NSArrayController's header, but I had to do some awkward things to make it work. I created an IBOutlet for my array controller, set the Interface Builder instance as that outlet, then was able to set the action of the NSPopupButton to a method in MyDocument which wraps setSelectionIndex: and passes the selection from the NSPopupButton to it. Obviously, I've already built this app with my own glue code. So I know how it can work. I've got my own reference, I just need to make more sense of bindings to make the NSPopupButton sync well with my array of text objects. My textView should change its contents to match selection. I can create new objects for the view. Heck, I can even make it work mostly, using a simple, single column tableView to do selections, but that gives trouble with nextKeyView. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Is there anything documented on what is and is not functional when a view becomes full screen? I have a view that when set to be very very transparent, only appears dark in full screen mode.

Re: NSGraphiteControlTint in app
Hello, I don't think the method setControlTint is the solution I'm looking for, because only a few classes have such a method, NSWindow doesn't. Maybe my question was to general. Is there a way without using private methods to set the complete appearance of an application to NSGraphiteControlTint, although the control tint in System Preference is set to NSBlueControlTint. I understand how important the appearance is to mac apps. But the NSGraphiteControlTint is used by some apps to give them a "pro-app" appearance. Do you really drag Apples "pro-apps" like Aperture into the trash, because they look different? ;-) I think for some few apps it is okay to violate the "Aqua-HIG". Aperture for example wouldn't look so great with a blue aqua appearance. Thanks, Ralph. Pro-Apps (FCP, Motion, etc...) use ProKit rather than AppKit and it is all private. iTunes has its own widgets it seems. iMovie may be somewhere in between. If you're wanting the look of any of those, you'll need to do one of 2 things: - build your own controls - use some controls somebody else built ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Binding a CoreData string value to an NSTextView
Has anyone had any success Binding a CoreData string value to an NSTextView? Everything I try seems to be flumoxed by the NSAttributedString of the NSTextStorage backing store. The lame thing is this: in code, it is easy to [aTextView setString: (NSString*)aString] or [aTextView string] So what's a reliable way to do the same thing but use a coredata string attribute as the source and destination here? Ideally with bindings to keep everything super clean. If need be, I can of course build some intermediary object. I'm not interested in attributes, but the intermediary idea may make this more practical anyway. Then the ivars of the intermediary could be bound to various attributes, if needed. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I have an NSTableView, and it contains NSTextAttachmentCell rows. There's only one column in the table view. Basically, when a user clicks on a row, I am getting the shouldSelectRow event, which gives me a row index. I need to know if the user clicked on the icon which is in the first 16 pixels of the row. To do this, I want to either find out the mouse position in general then normalise it to the control, or I want to capture mouse movement ( without any clicks ) and record it as I go, so I know when I click, what part of the cell was clicked on. I have found there's an event on a cell that would tell me the mouse position on a click, but I can't work out how to get the event, do I need to subclass NSTextAttachment and NSTextAttachmentCell to make my cell a new type that also tracks the mouse ? I get that impression from my reading, but surely I can just subscribe to an event ? If I could just ask for the mouse position on screen, and normalise it to my table view, that would solve all my issues. Thanks christian Christian, you might consider just adding a column that contains NSButtonCell for each row. With this , it will be a LOT easier to know that what you want users to click on was clicked on. This way, all you need to do is work on the appearance and not invent any wheels. (just put new hubcaps on the wheels) If all you need to know is if a button is clicked, use a button. In IB, drag and drop your image on the buttoncell and you're done, other than setting up notifications, actions or delegation. If you really, really need a button of a specific shape and hitmask, subclass NSButtonCell. (for this you'll want to read up on NSControl and NSButton and test subclassing those first) You don't need horizontal lines on the NSTableView, because you seem to want the rows to be seamless. You can still track the mouse location within any NSRect (within a cell's rect relative to the column's rect) but you're going to have to also keep track of the visible area if the view is resized and scrollable. Depending on what you're trying to do, and if you feel like bothering with it, you may also want to consider NSMatrix, but it's a PITA. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Targetting Tiger
Your best bet is to purchase a used Mac that can run Tiger and use it for test builds. There is a huge installed userbase of Tiger still, remember it has been the longest single incarnation of OS X.

An iBook G4 or even a dual-processor G4 PowerMac, or a G5 iMac would be totally affordable and reasonable options that would handle it well.) You second best bet, install Xcode 2.5 on Leopard.

Part of the localization process in Cocoa is to create your localized nib/xib files. This includes adjusting interface elements and layout accordingly so that it makes sense for different languages/cultures. Even some ready-made interface elements don't think left-to-right... so you may want to customize things appropriately. It all depends on how seriously you take given locale as a market for an app. As much as people sometimes think they want easy, scriptable, automated localization of the UI, it just doesn't work that way. You SHOULD hand-tool the UI for all locales. Do it like you're building something for your own children. When your users don't have to think, and even better, when they say to themselves, "oh!? That's clever, subtle, thoughtful!" then you have done a wonderful job. In the words of Apple: Surprise and Delight.

Create an NSCharacterSet constant
Hi All, Is it possible to create an NSCharacterSet constant? Attempting to do so with the methods for creating an NSCharacterSet naturally fails to compile with "initializer element is not constant" I would ideally like to be able to do this. Is it best just to declare a global constant string, then initialize an NSCharacterSet during app initialization? It certainly seems that is the only real option. Am I missing something? If I am correct in what I am seeing, would there not be a valid use case for this as an extension of NSCharacterSet? (BTW, thanks GCC for the less than clear error message which should say "you cannot run functions or methods in a global initializer" or something better.) ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

You can't create any non-scalar constant (except nil) using a static
initializer.
However, what you want to do is super-easy, and yes, it's a case for
an extension to NSCharacterSet. Just add a class method as a category:
@interface NSCharacterSet (MyCharacterSetConstant)
+ (NSCharacterSet*) theConstantCharacterSet;
@end
@implementation NSCharacterSet (MyCharacterSetConstant)
+ (NSCharacterSet*) theConstantCharacterSet
{
static NSCharacterSet* s_tccs = nil;
if( s_tccs == nil )
s_tccs = [[self characterSetWithCharactersInString:@"..."]
retain];
return s_tccs;
}
@end

Wow, you all responded wonderfully and super fast!
I had accidentally sent it to the list hours ago from the wrong email,
so it was naturally rejected, then I just now sent this.
Thanks to everyone, when I get a block of time I'll dive into each
approach and see how they all feel.
Anyway, I digress...
Category, yeah, that's totally one way I thought about, but I was
thinking more of an enhancement request in Radar. I figured the nature
of it inheriting from NSObject implies there are some kind of
optimizations under the hood (otherwise we'd just use NSString and
NSScanner right?).
Seems like a useful one considering the
characterSetWithCharactersInString: method. Even if it were some sort
of singleton class. Particularly useful in input validation routines
(things like highly structured serial numbers and other identifiers,
etc...)
If there is consensus from multiple people on an enhancement request
and the functionality and justification for it, I'll be happy to file
it.

I don't really see that there is a case here for a radar enhancement request, but it would depend on what you have in mind. As for optimisations, I don't quite follow your argument - NSCharacterSet is not equivalent to NScanner + NSString, though it sometimes will get used with those classes. I expect the common built-in "constant" sets are there because they are of very widespread utility - e.g. stripping whitespace, but are probably not using much in the way of magic optimisations. --Graham Indeed this is the point of Categories. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I figured the nature of it inheriting from NSObject implies there are some kind of optimizations under the hood (otherwise we'd just use NSString and NSScanner right?). An NSCharacterSet embodies the concept of "a set of characters." An NSString and NSScanner pair embodies the concept of "how I'm gonna find some characters in a string." The first is a value type, the second an implementation detail. NSCharacterSets are also useful for other things than just finding them in a string or other stream of data.

I see it as a useful thing to have predefined character sets that don't need to be managed. It's still just as simple to create them, but it sure would be nifty to not have to and to manage them in a constants file. At the very least, I will probably submit a radar on adding locale- specific standard sets. The standard set is woefully Latin-centric. Many languages do not use whitespace the same way (generally as word boundaries). Many languages also do not have the concept of capitalization. Japanese is one in which I happen to work. There would be a multitude of sets that would make sense in Japanese for a multitude of super common purposes. I know, some of this leads to things like tokenization. Point being, if we look beyond English and Western Europe, and consider how much of programming is pushing text around, it certainly seems like a logical expansion that would be of benefit to a lot of people. Maybe it's just me, not trying to hog the list. If anybody has some good sets for consideration, I'll be happy to include them when I create that radar.

Based on "sometimes it takes a long time" then that would indicate something is still happening. If a process is running from the dmg, then it cannot unmount until that process ends. Example: if you launch an app that is inside of a dmg, or on another volume external to the boot volume, you cannot unmount that volume until that app is terminated in some fashion.

Re: Controlling line-breaking in a text view
You might consider subclassing, but you might also want to read a lot more stuff first. Cocoa (and Carbon) text facilities are pretty deep. There is nothing about a bug in the text system. It is just that the text handling in Cocoa is very sophisticated and is designed to handle things depending on language and locale and function. Where and how to break words and what is a word can be a very complex subject, even just in one language. Even in page layout for print media, some things are hand-tooled.

Subclassing NSTextView
In Xcode 3.1, what is the minimum necessary to create a useable subclass of NSTextView ? (before adding/overriding methods) Additionally, in IB, is there any effective difference from using an NSTextView, selecting the text view within its scroll view and changing its class (in the inspector) to that of the subclass (say, MyTextView, for example) and selecting a custom view, setting its class to MyTextView and then selecting Layout > Embed Objects In > Scroll View ? I'm aware of the usual caveats leaning toward delegation and notification, but I'd like to do this as an exercise to better understand the capabilities of subclassing NSTextView. Even a link to a tutorial/walk through would be nice. I've already read Subclassing NSTextView in the developer docs, but it does not quite show me everything, it seems. In the feeble attempts I've made, when running the app, the custom text view places vertical lines where glyphs would be, and it does so starting at wherever in the view you initially click... ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Using Flex/Lex in a Cocoa project
Right now, I'm toying with using Flex/Lex in a Cocoa project. Unfortunately, I don't see a reliable or easy way to handle NSStrings correctly all the time with Flex. Does anybody have any suggestions for such text handling and reliable unicode aware regexes? I'm seriously not interested in implementing such details in C with Flex.

Flex is fast and cool for that, but if it's going to be stupidly difficult to use reliably with other languages on a mac, it's not a good idea for me. Depending on exactly what you need, unicode awareness can be fairly straightforward. Commonly, unicode in regexes is only needed to pass through undifferentiated blobs of text, with ASCII delimiters. For example, imagine parsing a CSV file which potentially has unicode text inside the quotes. For this case, you can convert the file to UTF-8, and then constructs like . will accept them. All non-ASCII characters in UTF-8 are represented as bytes 128-255, so if you just pass those through then you'll be fine. But be aware of some potential problem areas: - Each non-ASCII character will be more than one byte, and flex will think of it as more than one character. Write your regexes accordingly. In particular, avoid length limits on runs of arbitrary characters, and avoid using non-ASCII characters directly in your regex. - It's very difficult to split UTF-8 strings correctly. If you encounter a run of non-ASCII characters, ensure that you follow that run through the end, until you get back to ASCII. Don't have a regex that stops in the middle of it and then expects your code to be able to do something useful with it. - If you need to do something with non-ASCII characters besides read them in one side and write them out the other, for example doing something special with all accented characters, then Flex is probably not the right answer. Besides this it ought to be pretty straightforward. Since Flex just passes your code straight through to the compiler, you can write Objective-C in the actions (as long as you compile the result as Objective-C, of course!), convert the text from UTF-8 back to an NSString, and take things from there. Mike Thanks to all. Mike, your answer especially set it on the right path that Flex is not going to do what I would like to do, at least not without a lot of work that might be silly. Certainly, I could extract ranges of strings that are within the ranges of ASCII and apply rules to them and then lump other stuff into a separate group, but I'd like to have more control. If I were willing to just do ASCII, it would be a wonderful thing, since Flex is so fast. I understand well enough how difficult it can be to establish rules for unicode strings when there are a lot of semantics possible depending on the language. In my case, I am mainly interested in working with Japanese text, which does have difficulty due to a general lack of white space to rely on, but beyond that not so much more than a large character set. I want to be able to use Japanese strings as tokens throughout something. I seriously wonder how sophisticated syntax highlighting in Xcode really is... it does handle things quite well! As cool and wonderful as Flex is, it just isn't going to be reliable for what I want to do. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Personally, I think that in many cases, this should be no problem with the speed and capability of contemporary computers, but it could still be a drag. I have been looking at simply building an NSString of the same length with ranges of non-ASCII subbed out with some other character, just to do the lexing, then apply the results of the lex to the original NSString. For speed, it may even make sense to simply have two NSStrings going, one that is the real thing, the other that auto-substitutes anything non-ASCII. For this, my question to all is, what ASCII character would be good for the substitution without messing up the regexes? I'm considering some the unused control characters in the lower ranges, but I'm a little scared to see what will happen... Any suggestions on this idea?

Practically, quite difficult if you just don't know what object you should be binding to where! Quite the rabbit hole.

When dealing with applications (application bundles) by name or path, in Cocoa, when does it make a difference whether you use App Name.app example: Front Row.app or: /Applications/Front Row.app versus App Name example: Front Row or: /Applications/Front Row This seems to be pretty important, and I'm curious when and to what degree I should be cautious about the naming used in code. At this time I am mainly concerned about Apple apps themselves that should normally be in the system. Subsequently, is there any difference concerning 10.3 / 10.4 / 10.5 ? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Setting Minimum and Maximum width of Toolbar items
I've noticed that in IB 3, the Minimum and Maximum width of Toolbar items does not stick. You can enter it, command+S to save and then click done, and everything reverts back to 96px wide. One can only presume this is a bug or I don't know something.

RE: Setting Minimum and Maximum width of Toolbar items
Never mind. I have found the solution. The "Document" window in IB 3 must be in list view. In List, expand the tree of disclosure triangles from Toolbar Toolbar > Toolbar Item (name if any) With the Toolbar Item highlighted in List View, it is possible to get the sizing to stick in IB 3's Inspector palette. Incidentally, the list view is also a great way to wire things to the items in a toolbar...

Re: what do you use to make icons and similar?
: I believe png are really what I'm trying to make here, they seem to be recommended. PNGs are not resolution independent, although they are perfectly acceptable. Saving as a TIFF then converting it to PDF with Preview works well for me. Please excuse me if I missed something earlier in the thread, but my understanding of TIFFs (and PNGs and JPEGs) is that they're all purely raster formats. Thus, how does saving a TIFF as a PDF get you resolution independence? (At least that's what I read you to be saying.) steve It doesn't and it cannot. PDF is only a container, that happens to support vector art well, but cannot vectorize a raster image. If you properly placed some vector art into a pdf you might be able to garner some sort of resolution independence, but it's probably not worth the effort, and definitely won't look as good in most cases as well designed/optimized icons. Until displays approach something like 300dpi or higher, like print media, our eyes will be better served by icons hand-tooled for particular sizes. Your safest bet is to make use of PNG. It supports transparency. If you need something in .icns format, make use of Icon Composer. As for drawing/painting apps, don't be cheap! If you don't have skill, pay somebody to do it. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

How can i turn off the auto complete feature for NSTextField. I couldn't find any option in Interface Builder or the documentation of NSTextField. Thanx Are you sure you're using NSTextField and not NSTextView? The behavior is part of NSTextView and the two are a bit different. You'll need to override some methods, so you'll want to subclass. You might be surprised how often the completion is available in apps. NSTextField does not appear to have the same methods. Oddly, both do have the Delegate method control:textView:completions:forPartialWordRange:indexOfSelectedItem: This is pretty simple to take over. You just hijack it by giving it nothing!

compile and run without complaint.

Using CFStringTransform with Attributed strings or runs, maintaining the styling of the Attributes in transformed results.
Currently, I'm using CFStringTransform to convert Java-based strings files (JBoss .properties files) to something human-readable for verification. Works brilliantly. Luckily, these files are short and this function is super fast. This enables me to naively take all the text of a file provided or copied and pasted and convert it whole in one pass. My question is, will this function handle AttributedStrings? Presumably not. Is there a lazy way to handle this ?

Re: detect option key on startup
Depending on why you want to do this, you may want/need to try different approaches with mini-test apps to see what your results are. If you test with iPhoto for example, it does load the main menu nib, but loads a different nib than the usual main window for choosing or creating an iPhoto library. This should give you some indication of what is happening. The main app is completely launched, but the decision on what main menu items are available and what nibs are loaded is made early here. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

This will clearly involve me adding tons of IBOutlet ivars just so that at runtime I can set their text with NSLocalizedString APIs. One approach to avoid the whole IBOutlet excess would be to create subclasses of the standard view classes which, when they are loaded, use their contents/title as the key and pass it to NSLocalizedString (). That way, your NIBs only contain keys, and the .strings files can hold the actual strings, including comments. Another possibility: instead of creating a bunch of subclasses and having to specify that subclass for each view you create in IB, you could write a method that recurses through all views in a window. Check each view for a "title" or "name" property (maybe "stringValue" too), and maybe use some convention like #TITLE# to indicate you want to replace that title or name with a localized string to be gotten via NSLocalizedString(). Check whether the view is a table view that displays column headers, and if so, iterate through its columns. Do similar special-casing for tab views and segmented views and anything else that needs it. This method could be in its own utility class, where it could be called by awakeFromNib.

Re: Imitating Behavior of a Sheet Window
It might be worth considering simply loading a layer backed view. You may not need a full child window. If it is very different from a standard sheet, keep it different. Avoid confusing users. It's recommended to follow the HIG as much as possible. Sent from my iPhone ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Allow only root/admin users to execute the cocoa app
Just use parental controls on systems that non administrator users log in to. See the help menu. Sent from my iPhone On Jan 24, 2010, at 10:23 PM, cocoa-dev-requ...@lists.apple.com wrote: I want to allow my cocoa app to be only launched by root/admin users. How can i achieve this? As I think has already been mentioned, the UNIX approach is to set the application's owner as root and then make it only executable by the owner. However, Apple largely discourages programmers from developing Cocoa apps that will be run with root privileges. A better approach, if possible, is to factor out the section of code that needs to be run with root privilege (e.g., to read a protected file or open a network tap) and place that in a command line helper tool. The Cocoa app then runs with normal privileges. When the program needs to perform the privileged operation it calls that helper app (think of it as a kind of remote procedure call). Look up Apple's BetterAuthorizationSample code for how to do this. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

(if so heaven help me) Yes. There are. Japanese Keyboards will have a couple of keys for specific input switching. You will find frequently that the result of a key press plus a modifier key or modifier keys will produce totally different results in many locales. The question arises, what are you trying to accomplish?? Most things these days would look at what the USB device sends. All mac keyboards, even built in ones are on a USB bus. They do also emit "Mac Key Codes" but the layout of keyboards are different accross different models even just in the USA. example: black macbook F keys and their system control functionality. External keyboards usually do not have Fn key.
