Re: Core Data and ordered to-many relations
Didn't the OP want the relatives joined in a specific order (or, at least, be able to retrieve them in a specific order)? in the order prescribed. To do that, joins alone won't satisfy his query (Core Data structures are not guaranteed to return in any order). As I read them, his options were joins only or some other structure. In the OP's case, he'd need to have (as one possible solution) both a relationship entity and an order attribute of some kind in that entity to answer his request (the order attribute would also be as per dox). This would be the other structure, at least from my perspective. Peace, Love, and Light, /s/ Jon C. Munson II Quoting Jerry Krinock je...@ieee.org: If there's only two relatives, as in your example, use two to-one relationships. If there's an indeterminate number, you can add an intermediate joiner entity, as explained here: http://www.cocoabuilder.com/archive/message/cocoa/2007/9/16/189293 The above joins between two different entities, so you'll modify it to join the same entity. All data modelling situations are a little different. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

That's why I suspected you might be talking about some other compiler (my guess being Microsoft's, since that's the most common place where you might see a .obj extension). Anyway, the easiest thing to do is to put your C source files into your Xcode project and it will compile them and link them against the rest of your program.

Re: objc_exception_throw prior to launching nib file
You shoul post your code as it is difficult to discern your problem with the way you are describing things. In other words: Cannot perform operation without a managed object context What operation is being performed that could require an moc? If I set a breakpoint: In what, on what? the window (from nib) appears then gdb comes up What is strange is that the breakpoint should not be executed What do you mean by this? Breakpoints aren't executed, the debugger stops at that point (hence the term: break, meaning stop, and point, meaning place). You may then choose to execute the line at the breakpoint, or examine it, or whatever. The problem is not being able to debug the portion of code after the window appears. What are you doing that you can't do this? Is there a delegate missing? Are you certain that routine is even being called at all? If a managed object context were needed at that point, it should have said something when I run without code. No? Again, what do you mean, specficially by, when I run without code? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: SQLite 3 crash report - debugging help needed
How did you come by this crash log? From the 0x48, it looks like it's attempting to dereference an int passed into sqlite3VdbeExec where a pointer should go, but that's a wild guess. The crash log came from one of my testers. It's dying in sqlite3 code, so you have access to the source. Take advantage of that. If you can attach to it in the debugger around the time of the crash, you can observe the arguments passed into that last function call. How do I do that? That's something I haven't learned as yet.

Re: IB Plugin help
Namaste! Thank you Kevin and Josh! Josh: To clear up the assertion error, Clean All Targets. There was some junk not getting dumped out of the project on successive builds. Also, you nailed it with the TextLength key. HomerDoh!/Homer I took Apple's file comment of MyFirstKey literally. While not terribly new with KVC, this is my first plugin and I thought Apple may be doing something different. So, I took the comment at face value. After changing TextLength to textLength, the plugin operates as expected. Kevin: [A] 1. Yes. 2. com.JTAENTERPRISESLLC.JTAENTLLCTextLengthLimiter, com.JTAENTERPRISESLLC.JTAENTLLCTextLengthLimiter Here's the output of the two terminal commands: 1st command (known): com.JTAENTERPRISESLLC.JTAENTLLCTextLengthLimiter = /Users/jcmii/JTAENTLLCTextLengthLimiter/JTAENTLLCTextLengthLimiter/build/Debug/JTAENTLLCTextLengthLimiter.ibplugin; com.JTAENTERPRISESLLC.JTAENTLLCTextLengthLimiterFormatter = /Users/jcmii/StashWizG/StashWizG/JTAENTLLCTextLengthLimiter.framework/Resources/JTAENTLLCTextLengthLimiter.ibplugin; 2nd command (loaded): com.JTAENTERPRISESLLC.JTAENTLLCTextLengthLimiter I do have two remaining questions: 1. How do I change that blue cube (which displays when the textfield is selected) to my graphic (like NSNumberFormatter and NSDateFormatter)? 2. When I deploy my application do I need to deploy my plugin to the Library/Frameworks directory on the client machine, or is it enough to bundle it with my application? Many Thanks!!! Peace, Love, and Light, /s/ Jon C. Munson II Quoting josh hughes co...@brikbatrecords.net: Hi Jon, I tried compiling the project you attached but I was still getting Assertion Failures so I built the project from scratch again and it loads into IB without Assertion Failures (I think there is definitely something not setup right in the project you attached!). O.k First off, just to check; you are adding the framework to your live app, i.e... in Groupes Files (in your live app!): Browse to Frameworks and select Other Frameworks. Right click (ctl click) and navigate to Add-Existing Frameworks. In the open panel, browse to and select /Library/ NameOfYourFramework.framework. Click Add. Other Frameworks should now look something like this: Other Frameworks/ NameOfYourFramework.framework AppKit.framework CoreData.framework Foundation.framework It Is important your live app has the framework added to it as your plugin is dependent on it and will crash if it's not there! Sorry if you are already doing this, I thought It's better to make sure as this is quite important! Secondly, I think the reason IB keeps opening the new document window when you try and reopen the .xib is because the encoder is failing to encode the @TextLength property as it is not KVC-Compliant, so the component crashes when you try to save the xib, hence it also crashes when you try to decode/open the doc. I noticed that the component's console was spewing out errors when I tried to save or reopen an .xib the the component in it (in a live app): 009-04-05 12:32:51.436 Interface Builder[26488:10b] An exception was thrown during execution of an NSScriptCommand... 2009-04-05 12:32:51.438 Interface Builder[26488:10b] [JTextLengthFormatterView 0xaa82730 valueForUndefinedKey:]: this class is not key value coding-compliant for the key TextLength. I changed: [[keyPaths objectForKey:IBAttributeKeyPaths] addObjectsFromArray: [NSArray arrayWithObjects:@TextLength, nil]]; to: [[keyPaths objectForKey:IBAttributeKeyPaths] addObjectsFromArray: [NSArray arrayWithObjects:@textLength, nil]]; and this seems to have stopped the crashing when reopening the .xib. I have the project working here and can send you a .zip if you like? Hope this helps. All the best, Josh On 5 Apr 2009, at 01:10, jmun...@his.com wrote: Sorry for going quiet like that! I got distracted! No problem! :) I think that the fact IB is asking you to create a new document is a good thing! Actually, not in this case. The plugin seems to work fine within its project, so I decided to try and install it so I could use it in my other (live) project. I created a new window xib (imaginatively called test), put a textfield on it and saved it. Then, I added the formatter to the textfield, gave it a value of 5 and saved that. On re-open, IB then asked me what sort of resource to create - test was corrupted I suppose. I believe that when the project builds, the compiler automatically launches the target/s (in this case an IB Plugin Component/bundle) which in turn loads the plugin into IB and asks for you to create a new document (to test it out)!? So I think so far things are looking good! In the case of the plug-in only, yes, it seems viable. However, live is not the case. However, when I compiled the project, the component crashed IB, warning about an Assertion Failure:
Re: IB Plugin help
Namaste!
Is this the proper way to do that:
- (NSImage *)ibDefaultImage
{
NSBundle *myBundle = [NSBundle
bundleWithIdentifier:@com.MyCompany.MyPluginName];
NSString *someString = [myBundle pathForResource:@SomePic
ofType:@png];
NSImage *someImage = [[[NSImage alloc]
initWithContentsOfFile:someString] autorelease];
return someImage;
}
When I ran it, I got the nifty little icon rep of plug-in.

Quoting Brandon Walkin bwal...@gmail.com:
I haven't yet made an IB plugin with a custom formatter, but I'd assume
you change that image the same way you change the image that appears in
the document window. Return your own image in the -ibDefaultImage
method in your integration category.

I don't know why it thinks I have two plug-ins. If I run in release mode, it appears to load up and function EXCEPT upon re-loading a nib. I hadn't been running in debug mode once I got the plug-in actually working correctly, so there's got to be a change I made that caused this (that would be a Homer doh moment). What I mean is, if I put it in a live project by putting the framework in a more public place (like Library/Frameworks), then add it to a project, start IB, go into prefs-plugins and add it there, create a window nib, add a textfield to the window, then add the formatter, fill in the limit value, and save it, then close the nib, re-opening the nib results in IB asking what type of resource I'd like to create. I also noticed that under required frameworks the ibplugin file is displayed instead of the .framework file. I don't know how to fix that either.

Re: IB Plugin help
Namaste! Just want to pass on some further information. After that last post, the assertion error really bothered me. So, after a while of careful inspection (to the limits of what I know), I decided to and clean[ed] all targets of both the debug and release builds and re-compiled. In the plug-in project, runs of both debug and release went smoothly - IB loaded the plug-in, I was able to use it, close and re-open nibs successfully. No errors. Deploying the plug-in is proving difficult. I copied the release framework to Library/Frameworks. I also copied the framework into the frameworks section of a live project. I then created a test.xib in my live project, which I subsequently opened. In the Preferences-Plug-ins pane for IB, I attempted to add the plug-in. I got nothing - no error, nor plug-in. I then added the ibplugin file to the Resources folder of the version A of the framework. I then repeated the process of copying. This time, the plug-in appeared in IB. I added a textfield to test.xib, and applied the plug-in to it. I saved and closed the file. Upon re-open, IB didn't open the xib, but popped up the standard create a resource dialog - test had gotten kaboshed. I do notice that the Required Frameworks is displaying the .ibplugin file instead of the expected .framework file. I don't know if that is related or not. Again, I'll be happy to send up the project should you want to see it. Thanks! Peace, Love, and Light, /s/ Jon C.

RE:IB Plugin help
Namaste! Still plugging away at this... I found one mistake where I didn't change the IBInspector class of File's Owner in the Inspector.xib to my Inspector subclass. Doing that gave me an entry in the bottom box of the library, but no object in the middle pane... How do I fix that? Also, the image isn't displaying either. I'm still getting the book entries under the Formatter name. That being said, I also notice that my Inspector subclass doesn't have any sort of reference to my Formatter object. Is it supposed to? I should think it may need one. The dox don't really go into that so I don't know for certain. So, do I code it into the .h? And also the .m? Boy, I wish there was an example to follow... Thanks!

re: Core Data: is fetching safe during validateForInsert:/validateForUpdate?
Namaste! This is off-list. You know, I just went through this with the validateKey: bit. I found that a side effect of fetching during that validateKey was the save all pending changes bug. I then tried the performSelector, which worked, however, then the validateKey was no longer getting used properly (I was working through it to figure it out). That is, by using the performSelector, the validateKey was bypassed and not in-line (which makes sense after having thought about it). Boy, was that a bummer. I simply wanted to keep the user from entering the same code for two things in an attempt to help. I'm still working out how to get around that mess - probably need to keep some sort of global that contains a list against which to compare. This is NOT the purpose of a database unfortunately...anyway. For now I've simply commented out my validate code. In your case, though, I *think* the iClass example may be of help. See the number generator class contained therein as it does what you want (at least mostly). I'd avoid fetching whenever inserting, saving, or some other operation where you don't want to save stuff first, occurs. Would be nice if fetching had an optional parm to NOT save first and just deal with the current data... Just my two cents. Peace, Love, and Light, /s/ Jon C.

Re: NSTableView Popup Column issue
Namaste! Thank you for your reply. See my commentary below. However, my question still remains unanswered. Peace, Love, and Light, /s/ Jon C. Munson II Quoting Kyle Sluder kyle.slu...@gmail.com: On Fri, Feb 6, 2009 at 3:36 PM, Jon C. Munson II jmun...@his.com wrote: Well, using selection didn't work (now that I've had an opportunity to test it). It definitely needs to be arrangedObjects (or something similar). So, it isn't that. Arranged Objects is plural. Selected Object is singular. It should be apparent why this is not going to work out, and why you're winding up with the -description representation of an array in your popup menu. Table views, on the other hand, support multiple selection, so the bindings for NSTableView are plural: Selected Indexes. Actually, it isn't obvious. If it were, I'd get it. The reason selection didn't work (and I should have seen that earlier) is that it is singular in nature. If you create a form, with fields on it, you'd use selection as you are only dealing with one record at a time (in what I'm doing, selection is the same as currently selected record). This is simply not functional for a tableview as the tableview works off of collections of objects. Setting the SelectedObject binding of the popup column to arrangedObjects will correctly display the object's chosen display field data (for lack of a better descriptor) for each of the rows in the collection - selection will not. Selection only displays the value that is currently selected in the popup, regardless of the underlying data, and the same value is then displayed across all the rows. Why are you binding Selected Object to a collection of objects? Typically the Cocoa controls automagically set up their selection bindings when bound to a controller anyway. This is something that I have not seen documented, but that Apple employees on this list have confirmed. I know it's true for NSTableColumn. Are you saying that I don't need to bind the Selected Object of the popup at all? This is contrary to what I've seen in the samples. I'll give it a shot though as it is easy enough. Also, you are aware that Core Data allows for many-to-many relationships without intermediary entities (they are not called tables), right? I understand you have attached attributes to this relationship, and you need an intermediary entity in this case. Yes, Core Data does allow for many-to-many relationships. However, after a solid week of fooling around with trying to get that to work (there are only so many permutations one can use), I was not able to produce a working prototype. Nor did I see any samples that covered that particular arrangement. You are welcome to give it a shot though. Create a simple test. Two entities, Person and Hat. Many-to-many relationship. A person can wear many hats, and a hat can be worn by many people. I couldn't get this to function w/o an intermediary entity. Interestingly enough, the Core Data dox state that when SQLite is used as the store, in a many-to-many relationship, the intermediary table is automatically generated (which is the behavior I expect). Your naming convention is also rather screwy. It looks like Bastardized Hungarian (aka Anti-Hungarian Notation, according to Larry Osterman: http://blogs.msdn.com/rick_schaut/archive/2004/02/14/73108.aspx ). It conveys no useful information; in fact, since Cocoa (and KVO in particular) rely on the dynamic nature of the ObjC runtime, your prefixes are lying. And of course, they're incorrect, since there's no such thing as a table in Core Data land. I would suggest ending your prefixing habit now before you confuse yourself when what you thought was a tbl winds up being an _NSKeyValueObservingEntity in the debugger. The only naming convention rule I saw was that names need to begin with lower case letters (this due to macro facilitation for the creation of accessors, etc.). I use a naming convention that is particular to my needs, not the whole world or some purist's notion. Also, names should indicate the objects they represent. tbl, or table, is descriptive enough for me to know what it is without having to look it up somewhere else. And, isn't that the real point? Sure, we could argue what something really is, but that may not help you later - especially if there is a great deal of abstraction going on. If I had an entity that wasn't a table, I'd give it the appropriate prefix. Let's not get off on a tangent of naming things as that is definitely a matter of personal preference. What matters is that the code is readable, not too cryptic, and you can remember what you did later down the road with minimal commenting. As a tangent, when doing database design, one begins with entities but those turn into tables so, in reality, one is really designing tables. Entities are first used to described high-level

Re: Can't launch a new Window at click of a button
I second the printed material. Search for menu implementations as a
way to get started. Also, a book like Hillegass' Cocoa Programming
for Mac OS X Third Edition is a good place to start.
However, for expedience's sake, here's a kick start with but one way
to open another window from a seperate nib (you will need to know how
to create a controller class, etc., for the other nib):
In your implementation header file add (near the top, under the imports):
@class MyNextWindowControllerClass;
In the same file, add in your implementation section:
MyNextWindowControllerClass *myNextWindow;
In your implementation file add (under the main imports)
#import MyNextWindowControllerClass.h
In your code that the button will call:
- (IBAction)showMyNextWindow:(id)sender
{
// myNextWindow nil?
if (!myNextWindow)
{
// create a new needle window
myNextWindow = [[MyNextWindowController alloc] init];
}
// display the window
[myNextWindow showWindow:self];
}
This may not be the absolute best way but it does work.
Do review the calls, etc., as I'm sure you'll have follow-on questions.

Tracking down issue; Bad call?
Namaste!
In my app I have the following (a Save Panel call):
[sp beginSheetForDirectory:sDefDir
file:@
modalForWindow:[self window]
modalDelegate:self
didEndSelector:@selector(didEndSaveFileSheet:
returnCode:contextInfo:)
contextInfo:nil];
That call then calls this:
- (void)setDownloadPathName:(NSString *)aString
{
[self willChangeValueForKey:@mDownloadFolderPath];
mDownloadFolderPath = aString;
[self didChangeValueForKey:@mDownloadFolderPath];
}
sDefDir is a class member NSString that is set on awakeFromNIB (set to
NSHomeDirectory). I know it has a value because it is used to prior
to any of this stuff and works fine. It is only set in awakeFromNIB
and remains unchanged otherwise.
When I run the program and watch the call, hovering over the variable
shows me its value is invalid. Other runs show it has garbage data.
I assume this is why the Save Panel call jumps to where it does,
although why there I haven't a clue.
'Course this leads to me ask WHY is sDefDir invalid??? What happened
to it and where did it happen? I don't have any other place in the
code that sets sDefDir - only awakeFromNIB.
Anyone have a clue???
Thanks in advance!

[SOLVED] Re: NSTextField setStringValue not updating properly
I am posting this for the benefit of those who are coming into this area as new folk. Thanks to anyone who provided help. This is a short description of how I solved my issue and not meant to be a tutorial of any kind. After staring at it for multitudes of hours, I decided a different approach was necessary. What I ended up doing was implementing KVC and KVO for the variable with which I was experiencing trouble. This is (at least) done by creating a property, or by implementing the getter(s)/setter(s) w/ the appropriate key-value observing structure. There are probably a number of examples out there. Hillegass demonstrates that in his book (I keep touting it - it's good). I bound the textfield's value to the member of the class that was used. That addressed the issue of keeping the textfield up-to-date with the value of the variable as required. I did, however, run into another issue: the run loop. Coming from the VB world, I hadn't really needed any sort of variables (extremely rarely, if ever) that hung around. Most everything I did there stuck by nature of the beast (depending upon where it was declared). Here, however, one has to deal with the run loop. I may not have a complete understanding of it, however, the part that matters for this thread is that given a set of code it will only execute that code once and only on the information it has at the time of execution. Thus, if you need to pass data from one execution loop to another (think callback), it needs to persist. That's done either through the keyword static or, in the case of an NSObject of some kind, retain. In summary, changing over to KVC w/ KVO plus the retention factor fixed my issues. So, if you are having trouble with setStringValue, make sure you are going the KVC w/ KVO route check your bindings. Peace, Love, and Light, /s/ Jon C.

Re: how to pass arguments by reference

I've always seen (int *) as the declaration...
Quoting Dave DeLong [EMAIL PROTECTED]:
Spoke too soon... whoops.
Put an asterisk before the type, indicating that the type is going to
come in as a pointer to the data and not the actual data. Then when
you call the method, you use the ampersand to pass a pointer to your
data, like so:
(in some class definition somewhere. A C function would have slightly
different syntax, shown below):
- (void) foo:(*int)bar {
(*bar)++;
}
Then elsewhere,
int baz = 42;
NSLog(@%d, baz);
[someReceiver foo:baz];
NSLog(@%d, baz);
You should see 42 printed, and then 43.
If you wanted to declare foo as a C function, you'd do it like so:
void foo (int *bar) {
//same stuff
}
Welcome to the wonderful world of pointers.

NSTextField setStringValue not updating properly
Namaste! I've written a simple interface for ICA as part of my application. In that interface I have an NSTextField which holds a default path filename. Next to that field I have an NSButton for changing that information. It opens an NSSavePanel. I also have a Preview button that grabs the image on the scanner bed. This process downloads the file to a temporary directory filename. I pass the resulting path and filename via an IBOutlet which is hooked to the text field. These values can originate from the scan preview operation, the user typing, or the change button operation. The text field is not bound to any datasource. It *appears* to work on the surface, athough sometimes not even then. This is confusing the heck out of me. Anytime the value for the text field needs to change, I call [NSTextField setStringValue:(NSString *)aString]. After searching through the message archives, I either find bound fields or something else. The messages that address stuff close this stipulate using the above call. I have also tried validateEditing and display, both to no avail. I can't seem to locate another viable method to get the data stored (like a refresh). What appears to happen (in terms as best I can describe it, not necessarily technically correct) is that the text is written to the control's view, but, isn't saved to the underlying data structure. Thus, when I actually need the value later, I don't get what I see currently, but what was stored before. Hopefully that will make sense. In other words, it is as if there are two values: one for display, and one for data. They don't appear to get synched when I use setStringValue. So, my question is, what do I need to do to get the value actually stored and not just displayed? Thanks in advance! Peace, Love, and Light, /s/ Jon C.

Re: How Can I Notify DrawRect Method?
You both have valid points. However, I think you are missing something. That something being the overall goal of the application as predicated by that never-ever-returns: Time. That goal can be multi-faceted. For example, one item in the overall list is target platform. By deciding on what platform(s) to target, you can decide where to spend your time during to development to achieve the results you want. Sometimes that decision can also lead to split forks in the development tree (e.g., platform-specific support). Since I have found it nearly impossible to develop the perfect app before writing any code or going into some sort of demo mode, I favor an iterative design loop: get program parameters, code, test, check against parameters, check with client, lather, rinse, repeat. During that design/construction cycle, one should be able to identify what needs optimization, etc. That will cut down on the debate of technical theory - the proof being mostly in the pudding. Of course, the theory can help identify potential hotspots (items to watch) which can then be checked during testing cycles. Neither development time nor optimization are distinctly separate in my view - they are interdependent given the goal of the application. One may get favored over the other, but, again, that depends upon the restrictions placed by the goal of the application. Quoting Michael Ash [EMAIL PROTECTED]: On Wed, Dec 10, 2008 at 7:05 AM, I.

Re: how to manage two nib files
Not knowing why you need an apple event...here's my two cents (and boff on those who don't like my feelings): 1. find your printer (it is obviously installed, yes?) - you should know how to locate that in the Mac's resources. (get a list of installed printers/devices, etc.) 2. you should be able to determine from the installation parameters whether it is installed via USB or network. 3. in your cocoa app, in your main nib, have a an object that uses that information to determine which nib to load from there. If you need information on how to work with nibs, etc., see NSBundle. Also, see Hillegass' book Cocoa Programming for Mac OS X Third Edition (that's the one I have). I'm sure there are multiple appropriate references available otherwise (incl. Apple dox as previously pointed out). Hope this helps! Peace, Love, and Light, /s/ Jon C. Munson II Quoting XiaoGang Li [EMAIL PROTECTED]: Thanks. I have read these references, but I still have no idea about my issue, Maybe I did not understand them completely now, but I am worried that maybe I have not give a clear expression in my first email. Maybe I need give a more detailed description: this application is a utility for my printer, which be launched by the utility button on the Printer Setup Center. when user click the utility button, the Mac OS X will launch the linked application. and the application should first register an apple event, the Mac OS X then will send the apple event which used to tell my utility the printer model name and related information about the device. So, before the appliction be launched, it should get the apple event and check the printer name, then it will load the nib file dependently. If the printer is a USB printer, it will load a normal window to interact with user, if it is a Network, it will launch another application to do other things. So, I have no idea to design this application. I think this question maybe can not be implemented by cocoa application template, but I know that it seems no need to use NSDocument class. Thanks. 2008/12/8 Kiel Gillard [EMAIL PROTECTED] http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSWindowController_Class/Reference/Reference.html http://developer.apple.com/documentation/Cocoa/Conceptual/Documents/Concepts/WinControllersAndNibs.html#//apple_ref/doc/uid/2026 http://cocoadevcentral.com/articles/64.php Hope this helps!

If you want a Cocoa program (avoiding use of the word application to avoid confusion with an NSApplication instance) with a window in the GUI, just create a normal Cocoa application and be done with it. Maybe the OP can give a more thorough description of what he's trying to accomplish and why he wants a window but no other GUI elements.

Why have a window if you're making your user launch (and quit) the program from the command line?

Re: best practice to create Custom Objects represented by a image in a d-n-d operation
Hopefully this will come across well... If each ship you are dragging is a visual representation of a ship object, then, your receiver needs to be able to accept that object. While I don't know much about how drag-n-drop works (haven't implemented it yet), I imagine that what you need to know is well-covered in the documentation various examples as it is a basic/staple of a visual operating system such as Mac. Essentially, at least in older versions of Windows, you had some sort of object identifier that was passed and then the receiver acted on that identifier appropriately. Perhaps the newer systems will pass the whole object, or maybe (better) just a reference to it. Hopefully this will get you started. If not, just File 13 the message. Peace, Love, and Light, /s/ Jon C. Munson II Quoting Gustavo Pizano [EMAIL PROTECTED]: Hello. I have in a view images of ships, and Im able to drag them to another view which is the sea board, now, what is better, to create the objects of the ships in the shipsviewcontainer and set the object in the Pasteboard, or, just have representative images in the shipsviewcontainer of each ship, and once dragged to the sea create the instances of the ship that the images represent.

Device type list for scanners/cameras, etc...
Namaste! I'm working with ICA. Does anyone know any of the following: 1. What the list of device types are for connected devices? 2. Where I might find that list (in case you don't want to disclose it)? 3. Or, just the keywords for a scanner (I assume scanner but want to be sure) and a multi-function unit (I assume MFP but I want to be sure). I can't use the subtype method, so the corresponding kICA consts won't work in this instance - I need the full device type. Googling scanner camera device type values ICA didn't turn up anything other than the honorable mention in the Apple dox for camera. Thanks in advance! Peace, Love, and Light, /s/ Jon C.

Re: NSPredicateEditor and date comparisons
I remember, way long ago in the past, having to supply a time component to go with a date component - otherwise some seemingly random time was inserted which then threw off anything else I did. If I only needed a date (from a datetime field), I had to format it that way (as only a date, and in the format I needed) and do some seemingly-odd comparison (like comparing two strings). It worked, so I didn't care past that point. Quoting Chris Idou [EMAIL PROTECTED]: Would your time zone happen to somehow correspond to 8:00 ? Try doing a setDateValue on the gui component before you start, with a particular time. I've got a suspicion that it will then leave the time component alone. When you got a result of 13:41:40, might that have been the time you ran the program? --- On Sun, 7/12/08, Josh Abernathy [EMAIL PROTECTED] wrote: From: Josh Abernathy [EMAIL PROTECTED] Subject: Re: NSPredicateEditor and date comparisons To: [EMAIL PROTECTED] Cc: Cocoa-Dev List cocoa-dev@lists.apple.com Received: Sunday, 7 December, 2008, 5:00 PM Ah, yes, that would be the more accurate way to explain it. I have an NSDatePicker in my NSPredicateEditor and no funny business is going on with conversions. It's just the simple default, setup-in-IB usage. So I guess the question is better put: is there any guarantee about the time of an NSDatePicker in an NSPredicateEditor?

NSPredicateEditor doesn't compare any dates, it just creates NSPredicates. Maybe you're saying that if you have a NSDatePicker in your NSPredicateEditor, that it creates a predicate with a date set to 13:41:40. If that's the case, then it probably has more to do with the NSDatePicker than predicates. Unless you're converting the predicate to a string, which introduces more complications. NSPredicateEditor tends to just call objectValue on the gui component, so try calling that yourself on your NSDatePicker and see what happens. --- On Sun, 7/12/08, Josh Abernathy [EMAIL PROTECTED] wrote: From: Josh Abernathy [EMAIL PROTECTED] Subject: NSPredicateEditor and date comparisons To: Cocoa-Dev List cocoa-dev@lists.apple.com Received: Sunday, 7 December, 2008, 11:14 AM Hi all, In my application, users have the option of comparing to a date in an NSPredicateEditor. For the NSDates it is comparing against, only the date is important; time doesn't matter. The interesting thing I found about NSPredicateEditor is the NSTimeInterval it compares my NSDates to has the time set to 13:41:40. That means my NSDates with the default 12:00:00 time don't match an is predicate. It's not a big deal because I can just change my NSDate's time to 13:41:40 to fix the problem.

Re: What are the limitations of Dot Syntax?
Namaste! I'm going to add my two cents here (despite being a noob). I like the dot syntax. Why? (and before I go any further, I realize this is not a Windows forum, and also realize this is a very general set of statements and quite open to debate) Because, in the Windows world at least, the dot allowed you to refer to *members* of an object. What are members? They are attributes of the object. In programming simplicity, they are: properties or methods. So, what's wrong with the dot syntax? Nada in my book. A fuller implementation of the dot syntax is more desireable in my book. From whence I came, it sure made code very much more readable and quicker to write. That being said, I don't have an issue with the way things are, nor do I really care much how they evolve, provided the evolution is for the better. The bottom line, as long as your code is readable, digestible, consistent, and clearly commented in tricky spots for those who come after you (and yourself later down the road too), it really doesn't matter, does it?

Re: Various syntax errors and ICA kit
Namaste!
OK, after much beating of head against wall, I found the issue.
'Twas the way the #import statements were set up. Once I moved the
Cocoa Carbon imports to the header file that cleared up quite a bit
of my issues. Also, I believe I had some of my own ignorance tossed
in as well. Made one heck of a salad...
Peace, Love, and Light,
/s/ Jon C. Munson II
Quoting [EMAIL PROTECTED]:
Namaste!
Also, if I take out the #import statement from the .m file, I get a
compiler warning about a forward class. I don't know if that means
anything truly important or not (but that was when i figured I forgot
the #import part). If I can ignore that, then I may get my app to
compile and run properly...
Peace, Love, and Light,
/s/ Jon C. Munson II
Quoting [EMAIL PROTECTED]:
Namaste!
And so the fun ensues...
I'm working with the (slightly, deprecated in 10.5) older ICA (as the
newer doesn't work).
I've brought over the code base from the SampleScanner application in
the Carbon-ImageCapture-Examples folder and applied it to mine own
form.
Before I attempted to integrate it fully into my app (meaning, actually
call it from the form that needs to call it), the nib controller
files compiled just peachy (no errors, just deprecation warnings
mostly).
So, I added it to my calling window (instantiated the class, #imported
the header, and so on) and created a method a button could trigger.
Now, however, my application won't compile. It complains of syntax
errors in the ICA form's header file:
Syntax error before ICAObject
Syntax error before ICARegisterEventNotificationPB
Syntax error before ICAScannerStartPB
Fatal error: method definition not in @implementation context
If I take the header import out of the .m file for the calling window,
and comment out the calls to the ICA window, the app compiles fine and
executes ('course, I can't load the ICA window :( ).
My ICA window is identical (with the exception of an icon image at this
point) to the SampleScanner window. The .h .m controller files are
also identical (except for log, which I removed as I don't need/want
that part).
Anyone got a clue on this?
I almost have this hooked in...so close...
Thanks!
Peace, Love, and Light,
/s/ Jon C. Munson II

Re: NSImageView gets stuck
Shot in the dark here...
I noticed you are using ballFrame in your timer event, but not in your
reset event.
Is that your issue?
Quoting Michael Rogers [EMAIL PROTECTED]:
Hi, All:
I have an NSImageView (in a variable called ball) that I am trying to
move programatically across the screen, and when it hits a wall,
reposition it in the center. I've set up an NSTimer, and in the
timerFireMethod have this:
NSRect ballFrame = [ball frame];
ballFrame.origin.x+=ballDeltaX; // move the ball
ballFrame.origin.y+=ballDeltaY;
works just fine, the ball merrily moves across the NSView. However,
when I hit the wall, and do the following:
[myController victoryGoesTo:'R'];
[timer invalidate];
[self placeBallInCenter];
the placeBallInCenter method fails:
-(void)placeBallInCenter{
[ball setFrameOrigin:NSMakePoint(125,125)];
NSLog(@ball frame: %@,NSStringFromRect([ball frame]));
}
The ball's origin displays correctly in the console as (125,125), but
the ball is stuck on the right hand side of the screen, at around 400.
I'm using the same technique in placeBallInCenter as I did in my
timerFireMethod, so I am perplexed.
Thanks for any enlightenment,
Michael

ICAHandler
Namaste! OK, here's my first question: What is an ICAHandler? The compiler complains of it and I can't find it in the documentation anywhere. The ICA API Tester app lists it in the code it creates for ObjC Async. Any thoughts? Peace, Love, and Light, /s/ Jon C.

Re: ICAHandler
Not sure.
What I'm referring to in my post is this:
[code]
// -
ICAGetDeviceListCallback
void ICAGetDeviceListCallback (ICAHeader* pbHeader)
{
ICAHandler * obj = (ICAHandler*)pbHeader-refcon;
if (obj)
{
[obj getDeviceListCallback: (ICAGetDeviceListPB*) pbHeader];
}
}
[/code]
This is what ICA API Test spits out. Where did ICAHandler come from???
Thanks!

It looks like a class in some sample code; IOW, not a built-in class.

ICA Documentation issue
Namaste! After having read through the ICA API documentation looking at the sample apps, I've noticed: 1. The online dox appear to be ahead of anything else (although I'm not certain). 2. The sample apps employ deprecated calls and are written w/o conforming to the dox. 3. The ICA API Test app also does not quite match up to the written material. Anyone have a working, up-to-date sample for a simple scanner/camera interface he/she would care to share? Implementing code generated by the ICA API Test app is throwing errors that I'm not easily tracking down. Thanks! Peace, Love, and Light, /s/ Jon C.

ICA isn't part of Cocoa, so you won't get a good answer from this list, but I can indeed confirm from experience that: 1) the documentation is weak 2) newly-introduced functions in 10.5 (such as for downloading images to RAM) are completely broken 3) it is therefore best to continue to use the deprecated APIs If you will be relying on lots of ICA features, be prepared for many long nights.

Re: New to Cocoa and Objective C, and I need some basic pointers
Again, Hillegass' book, Cocoa Programming for Mac OS X is excellent. I've a smattering of experience in a number of languages and found his book an excellent introduction to the whole bit. Quoting Benjamin Dobson [EMAIL PROTECTED]: The OP has sent me the original message body off-list. The rest of this message is what the original message was meant to say. ––– I've been programming almost exclusively in Java since 1998, and between 1985 through 1998 I was using C and C++. I just started learning Objective C, and found the language pretty easy to use. However, I need some pointers on the best way to become familiar with some of the Cocoa libraries and classes as well as the Foundation. In Java, they have what I think is a great API reference for all the normal classes. For those of you that have never seen it, just so you'll know what I'm talking about, here's a link: http://java.sun.com/javase/6/docs/api/ With this you look up the name of a class on the left column, click on it, and the detail regarding the class shows up on the main section of the page. I'm new to this with Cocoa, and I've been looking for something similar to that above. I have found, for example, the Foundation Reference Collection for Objective-C, the Application Kit Objective-C Reference Collection, and a host of other similar type pages in the developers documentation. Each such page displays what can be long lists of classes, and if you click on one of the Class References, up comes a page with more detailed information. The information looks pretty decent, but I end up using the back button on the browser to navigate. Is there a better, easier API layout? Additionally is there one that would include nearly all frameworks in one list? Also, I've noticed that some of the newer Objective C texts are using the dot notation. Is this going to be the norm in the future or was this something added to make Objective C easier to port from Java, C++, and even C in some cases? Last but not least, what are the best books available for learning Objective C and Cocoa? I've had little problems with Objective C (except adjusting to the notation) so I assume I would want to focus primarily on Cocoa, and I'm assuming any decent Cocoa book would probably delve into the Foundation as well, since I don't see how it couldn't (that's just my opinion).

Various syntax errors and ICA kit
Namaste!
And so the fun ensues...
I'm working with the (slightly, deprecated in 10.5) older ICA (as the
newer doesn't work).
I've brought over the code base from the SampleScanner application in
the Carbon-ImageCapture-Examples folder and applied it to mine own
form.
Before I attempted to integrate it fully into my app (meaning,
actually call it from the form that needs to call it), the nib
controller files compiled just peachy (no errors, just deprecation
warnings mostly).
So, I added it to my calling window (instantiated the class, #imported
the header, and so on) and created a method a button could trigger.
Now, however, my application won't compile. It complains of syntax
errors in the ICA form's header file:
Syntax error before ICAObject
Syntax error before ICARegisterEventNotificationPB
Syntax error before ICAScannerStartPB
Fatal error: method definition not in @implementation context
If I take the header import out of the .m file for the calling window,
and comment out the calls to the ICA window, the app compiles fine and
executes ('course, I can't load the ICA window :( ).
My ICA window is identical (with the exception of an icon image at
this point) to the SampleScanner window. The .h .m controller files
are also identical (except for log, which I removed as I don't
need/want that part).
Anyone got a clue on this?
I almost have this hooked in...so close...
Thanks!

Re: Programmatically loading an NSImage via other field
In response to all the responses...
This monitoring needs to happen whether the user types in a field,
or, there is a choice made via NSOpenPanel, or the record is scrolled
(meaning moved next, moved previous).
So, using the beginning of the KVO below (which is the route I
suspected I'd have to go, but not sure exactly how), would I need to
add other delegate methods to handle the other cases?
Also, is dragging the delegate from the text field to the File's Owner
the same as the awake from NIB call, or do I need to add the
awakFromNIB as well?

Re: Programmatically loading an NSImage via other field
In continuance...
Alright, so it isn't strictly KVO...:) But it looks like it...:)
Anyway, is there a way to know when the stuff in the cell changes?
Most everything I can find is relative to when the user interacts with
the control. But I can't find anything, as yet, for when the user
doesn't, but the code does...
For instance, when the window displays, there is a value in the text
field for the path/image. Yet the image doesn't load. Is there an
event/method that I can utilize to push the image? I only found
windowDidLoad, which didn't do it.
It also appears that I'll have to implement mine own
MoveNext/MovePrevious methods in order to push the picture (although I
still need to test that first).
Thanks!

Re: Programmatically loading an NSImage via other field
Namaste!
OK, I've been playing around with this for too long now...
NOTHING gets called when text in a control is set via code or a
mechanism other than strict keyboard/mouse entry by the user from what
I can determine. This, in a word, is not good.
I've set up an observer, delegates, and all that, per previous posts
and only when keys are actually pressed do the delegate methods get
called.
Also, I've noticed that when the record is moved (either next or
previous), there is a buffer time between when code executes and the
interface gets changed.
Thus:
- (IBAction)movePrevious:(id)sender
{
[tblPattern selectPrevious:self];
[btnPrevious setEnabled:[tblPattern canSelectPrevious]];
[self pushPicture];
}
Doesn't work. The Apple dox state the reason the move action is moved
to another process is to give the error mechanism a way to respond.
As a consequence, nothing changes and the code executes, then the
stuff changes. What happens is the previous image gets loaded as the
current image, despite what the textfield says.
Not good.
For a simple OnChange thing, this is absolutely frustrating (and has
resulted in quite a bit of code).
Bottom line is, it looks like I need some way to see changes that
were made to either the underlying Cell (thinking along the lines of
display changes) or some other route to take this.
I have three scenarios under which the image needs to get pushed:
1. When selected from a file.
2. On Window display - first record is displayed.
3. When records are scrolled (Move Next/Move Previous).
I've solved #1, though I don't like having to manually push the
image (meaning I call the pushPicture routine). 2 3 are still
unsolved at this point.
Any further thoughts??? Anyone else only keep paths to images and
dynamically load from that data? Storing the pictures in the data
structure is not going to happen as they'll take up far too much space
and suck resources.
Thanks for all the help so far!

I'll take a look at at it.
I'm still a Windows guy. Actually, I'm becoming dual-platform. Now

Quoting Matt Long [EMAIL PROTECTED]:
Jon,
I'm not sure I understand the whole problem here, but from your initial
message I put together a simple demo project that will take the input
value from a text field and use that as the path for an NSImageView. It
does it on the fly (e.g. as you type). Here is the demo project:
http://www.cimgf.com/files/AutoImageLoad.zip
On first run, use the Browse... button to locate an image and select
it. The image will display. Then start to backspace from the end of the
path in the text field and you'll see the image you selected
disappears. Then type back in what you backspaced out and you'll see it
reappear. This is all done with the magic of bindings. The text field
value and the image view's value path are both bound to the same
string. When the string gets updated, so do both of those fields.
You'll see the string that is being used for this is a @property of my
AppDelegate class.
Let me know if you have further questions. I'm a former Windows guy
myself and can probably help you unlearn what you know as I also had
to do. ;-)

posts and only when keys are actually pressed do the delegate
methods get called.
Also, I've noticed that when the record is moved (either next or
previous), there is a buffer time between when code executes and
the interface gets changed.
Thus:
- (IBAction)movePrevious:(id)sender
{
[tblPattern selectPrevious:self];
[btnPrevious setEnabled:[tblPattern canSelectPrevious]];
[self pushPicture];
}
Doesn't work. The Apple dox state the reason the move action is
moved to another process is to give the error mechanism a way to
respond.
As a consequence, nothing changes and the code executes, then the
stuff changes. What happens is the previous image gets loaded as
the current image, despite what the textfield says.
Not good.
For a simple OnChange thing, this is absolutely frustrating (and
has resulted in quite a bit of code).
Bottom line is, it looks like I need some way to see changes that
were made to either the underlying Cell (thinking along the lines
of display changes) or some other route to take this.
I have three scenarios under which the image needs to get pushed:
1. When selected from a file.
2. On Window display - first record is displayed.
3. When records are scrolled (Move Next/Move Previous).
I've solved #1, though I don't like having to manually push the
image (meaning I call the pushPicture routine). 2 3 are still
unsolved at this point.
Any further thoughts??? Anyone else only keep paths to images and
dynamically load from that data? Storing the pictures in the data
structure is not going to happen as they'll take up far too much
space and suck resources.
Thanks for all the help so far!

Re: Programmatically loading an NSImage via other field
Namaste!
Back so soon...
:)
OK, I took a look a what you have and have some questions.
And, well, h...
I'M A DOPE!! :D
No questions!
The reason for that is I was under the extremely mistaken impression
that I couldn't load the ImageView from a simple path via a binding.
I took a look at how you had your ImageView bound and voila! The
answer was staring me straight in the face! ROFL!!!
Can I say OMFG?
Geez...
But I did learn some things along the way so it wasn't a total loss...
I now return you back to your regularly scheduled program...
THANKS!!!

p.s. Isn't it always something simple???
Quoting Matt Long [EMAIL PROTECTED]:
Jon,
I'm not sure I understand the whole problem here, but from your initial
message I put together a simple demo project that will take the input
value from a text field and use that as the path for an NSImageView. It
does it on the fly (e.g. as you type). Here is the demo project:
http://www.cimgf.com/files/AutoImageLoad.zip
On first run, use the Browse... button to locate an image and select
it. The image will display. Then start to backspace from the end of the
path in the text field and you'll see the image you selected
disappears. Then type back in what you backspaced out and you'll see it
reappear. This is all done with the magic of bindings. The text field
value and the image view's value path are both bound to the same
string. When the string gets updated, so do both of those fields.
You'll see the string that is being used for this is a @property of my
AppDelegate class.
Let me know if you have further questions. I'm a former Windows guy
myself and can probably help you unlearn what you know as I also had
to do. ;-)
Best Regards,
-Matt

Trouble with array controller - array
Namaste! OK, I'm confounded... I've got an outlet (tblUser) that's an NSArrayController. It is pointing at an Array Controller in my NIB called tblUser. That is point at an Entity called tblUser. The MOC is set up correctly. In my code, I've assigned an (NSArray *) aUser to [tblUser arrangedObjects]. I then proceed to get a count of objects from the array ([aUser count]). For some reason, I get a value of zero. Yet, in another screen, same app, same instance, the count is correct at 1. Same bits of code, only the names are a little different, but the syntax is the same. Anyone care to posit theories as to why this might be happening? Did I miss an intermediate step somewhere?

Programmatically loading an NSImage via other field
Namaste! OK, I'm beat for the day... I'm struggling with how to load an image into an NSImage via another field's value. I have a field that contains a path name of an image file. The user can type it in or select it via OpenFile sheet. This works just fine and I'm setting the underlying data object so the value persists. Now, my question: how do I get that value to propagate over to the image? In Windows, I can monitor via the onChange event for the textbox. Piece of cake. Here, though, I'm a bit perplexed. I thought perhaps the textDidChange delegate method might do it (I put that in my File's Owner, and made the File's Owner a delegate of the NSTextField that contains the image name). However, it doesn't fire e'en though the text clearly changes (onscreen). So, how do I accomplish this should-be-easy feat? Thanks! Peace, Love, and Light, /s/ Jon C.
