Re: noob q: adding a button to a window programmatically
You haven't set the button's frame size. If you use -initWithFrame: and pass something sensible that should work. Note - because NSButton subclasses NSView, the designated initializer for NSView (initWithFrame;) must be used. hth, Graham On 10 Jun 2008, at 3:28 pm, Stuart Malin wrote: Until now I have created my GUIs using IB.

Spotlight sources w/o actual files?

Hi Rasmus, You do need to have one file per findable item, and you cannot get a callback at search time.

Re: App hangs when displaying any sheet in 10.5 [SOLVED]
Ah ok. I was bit by something similar a few years ago. I had forgotten to put the prototype in my class interface and believed the compiler was using a prototype from an unrelated class which had different arg and return types. But the twist was the missing prototype caused the default id return and '...' arg types to be used (determined through asm studying). The presence of the other class's prototype was just suppressing the usual 'may not respond to selector' warning. As far as trashing memory it was very likely trashing a floating point register your calling code was using and eventually using the trashed value for calculations and/or storing it to memory. For instance on i386 it might have had a float the calling code was using in fp0 and expecting the return value of your called method to come back on EAX, therefore believing fp0 would stay unchanged. But the called method was writing its return in fp0 (destroying the original value) and the calling code was casting whatever junk was in EAX to your float. Actual register names might differ but the effect is the same. On Jun 8, 2008, at 6:29 AM, Graham Cox wrote: No, this is not it. The method definitely did have a prototype - in fact it had *two*, differing only in return type. Judging by the assembler code, it used the one returning an int (actually an enum) not a float. It's still unclear why this generated code that trashed memory, but it did. It also did silently cast the result as well, which is perhaps why no warning was issued, because in some cases that's the desired behaviour. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Where are these types of prefs located and is it safe to just zap them? Your prefs file will be in ~/Library/Preferences/YOUR BUNDLE ID.plist. The window frame prefs are stored in the NSWindow Frame palette name here item. It should be safe to either delete the entire prefs file or just the individual item. If this is an already released product, it might be nicer to just rename your autosaveName to : e.g palette name V2. That way if they run your old version, the old pref will still be valid for the version of the palette in the original key. Dont worry about filling up your prefs with obsolete keys, its not a major drain on resources.

Re: warning: return makes pointer from integer without cast
Hi Steven-
Your method signature says the method returns an object (id), but
your return values you give back are int. I think that may be where
your code is making a pointer from an int without a cast.
I'm guessing you are implementing this as an outlineView datasource...
in this case, the correct method signature is returning an int.
Hope this helps!

Your method declaration is wrong - outlineView:numberOfChildrenOfItem:
returns an NSInteger, not an id.
id is a pointer, hence the warning.

Re: warning: return makes pointer from integer without cast
Hey Steve,
In this case, you are returning a regular integer (count returns just
a regular, scalar type). But you've declared your return value as id,
which is a typedef for a type of pointer. You either have to return an
actual integer, or wrap the return of count in an object like NSNumber.

Controller, any idea how to add delegates to this object? or, any tutorials for
this? Thanks,

Re: adding a delegate to a class
Hello Angelo,
I think this code might help you:
@protocol BackgroundObjDelegate NSObject
@optional
- (void)showText:(NSString*)text;
@end
@interface BackgroundObj : NSObject
{
idBackgroundObjDelegate _delegate;
}
@property(assign) idBackgroundObjDelegate delegate
- (void) sayHi;
@end
@implementation BackgroundObj
@synthesize delegate=_delegate;
- (void) sayHi
{
if ([_delegate respondsToSelector:@selector(showText:)])
[_delegate showText:@Hi];
}
@end
Then, you could implement your delegate class, for example:
@interface ForegroundObj : NSObject BackgroundObjDelegate
{

Hi,
I have a code like this:
@interface BackgroundObj : NSObject
{
Controller *mc;
}
- (void) sayHi;
@implementation BackgroundObj
- (void) sayHi
{
[mc showText:@Hi];
}
@end
As you can see, the code is hard coded to use class Controller, can not be
used with any other object, I'd like to add a delegate which will have a
showText method, sayHi method will just call the delegate instead of hard
coded Controller, any idea how to add delegates to this object? or, any
tutorials for this? Thanks,
Angelo

Re: Building against 10.5 SDK, link error on open
It's possible the SDK has a problem, but first double-check everything you're using (and everything it depends on) to be sure it's built with consistent headers and libraries. If it's C++, the compiler version is also important. You may have to examine the list of environment variables printed at build time, and the GCC command lines, to see the problem. For example, the -isysroot option may not be set correctly. Another test would be to disable the SDK temporarily and build against Leopard itself, just to see if the results are the same. Kevin G.

Re: Garbage collector vs variable lifetime
On Jun 9, 2008, at 5:55 PM, Hamish Allan wrote: Sure. But it gives you *more* information than if it just returns id. I agree with you in all other respects of your post, but I don't agree that +[NSArray array] returns id because if it returned NSArray * you'd have to have a separate declaration for +[NSMutableArray array]. Indeed, that line of reasoning leads to John's way of thinking: that if you return something more specific than id, it is in some sense indicative that the returned object is more likely to be of a specific class, rather than a subclass thereof. I think the problem is that if NSArray has +[NSArray array] returning an NSArray, then NSMutableArray has to return an NSArray also, since it can't have a different method signature for the same method. As a result, if you called +[NSMutableArray array], the compiler would think you were getting a regular, non-mutable NSArray, and you'd get a warning if you tried to do this, although the code would still work: NSMutableArray *array = [NSMutableArray array]; The only way to get the compiler warnings to shut up would be to cast it. If the methods return id, then the compiler just assumes you're doing the right thing (which also means you can do stupid things like assign +[NSMutableArray array] to an NSString or something which would of course end up blowing up before too long, so it's not perfect either, but it's certainly less annoying than having to typecast every assignment of a newly-initialized NSMutableArray).

NSSlider responding to superview's drawRect
Hi All, This is something that I haven't seen before. I have a custom view that inherits from NSView directly and just draws a gradient background. In IB I've placed an NSSlider on the view which works fine. The problem comes when drawRect in my custom view is invoked, I draw the gradient and a 1px line at the top of the view, but the line also gets draw just above the NSSlider! logging shows the following 1) resize window - drawRect is called and the line above the slider disappears 2) move slider - drawRect is called from my gradient view but with the frame of the slider. The line then appears. Is this a known issue with NSSlider and a custom view or have I missed an idiosyncracy of NSControls.

Re: NSSlider responding to superview's drawRect
Check the code that draws the 1-pixel line.

Re: NSSlider responding to superview's drawRect
You're probably filling your gradient into the rect passed in drawRect. That rectangle just represents the dirty part of your view. If you had a solid color to draw, you could just fill the rect, but with a gradient you will get your gradient, top to bottom, within this possibly small rect within your view. Try drawing the gradient into [self bounds] instead. This describes the location of the entire view in its own coordinate system. -Ken On Jun 10, 2008, at 8:51 AM, Jonathan Dann [EMAIL PROTECTED] wrote: Hi All, This is something that I haven't seen before.

Sure. But it gives you *more* information than if it just returns

+[NSMutableArray array]. Indeed, that line of reasoning leads to
John's way of thinking: that if you return something more specific
than id, it is in some sense indicative that the returned object is
more likely to be of a specific class, rather than a subclass thereof.
I think the problem is that if NSArray has +[NSArray array] returning
an NSArray, then NSMutableArray has to return an NSArray also, since
it can't have a different method signature for the same method. As a
result, if you called +[NSMutableArray array], the compiler would
think you were getting a regular, non-mutable NSArray, and you'd get a
warning if you tried to do this, although the code would still work:
I'm not sure if I follow you, but the trivial example below compiles with only
one warning. NSMutableArray could redeclare the superclass' implementation of
+array, but that would have to be done for each factory method that presently
returns an id, which is pretty annoying. In addition, each successive subclass
has to redeclare /and/ reimplement all of the factory methods. Another
example: if you subclass NSFontManager using setFontManagerFactory:, every time
you call +sharedFontManager you have to cast to your subclass since it's
strongly typed.

Thing *a = [Thing thing];
a = [MutableThing thing];
MutableThing *b = [MutableThing thing];
// warning: assignment from distinct Objective-C type

Selectable NSTextFieldCell and NSTextField break attributed strings when selected
Hello! this is my first time posting on this mailing list so I hope I do not forget to provide any necessary details! I've been searching around for a long while to fix this problem I am having and I have yet to find a solution or an explanation. I have a NSWindow with a few NSTextField instances and a few NSMatrix instance containing various numbers of NSTextFieldCell instances. None of these NSTextField and NSTextFieldCell instances are Editable. Only a subset of them are Selectable. The formatted content of my fields has been programmaticaly entered using the setAttributedStringValue message and this formatted content often contain more than one Font Family and Font Size in the same NSAttributedString. My problem is that when I select the content of those fields, the Attributed Strings they contain lose their formating and the Font Family and Font Size becomes unified. How can I make sure the formatted content I have prepared remains unchanged when I select it?

The C string APIs don't have a particularly special place as far as security vulnerabilities go. No, it's not. A common technique is to use C string APIs to find line endings, then try the full line as UTF-8. If it fails, then you can fall back on a more forgiving encoding. Yes, I do try UTF-8 first. Sorry, I was being brief in the previous message, describing only the _fallback_ if UTF-8 parsing fails. I'm not sure why you would want to use C APIs to look for line endings first, though? When working with streaming data then you need to find a delimiter to safely cut the stream before trying UTF-8, because if the end of your chunk of data ends in the middle of a UTF-8 code word (or whatever it's called), then the result will be invalid UTF-8 even if the stream as a whole is valid UTF-8. You could write a UTF-8 parser to find good cut points, but it's much easier when working with a line-oriented protocol to just look for CRLF.

This lets you start a modal window, run it at intervals to keep events processing, then close it when done. Of course this requires putting your progress bar in a modal window, but if you're not going to allow the rest of the program to run then this is a good idea anyway.

Well, FWIW, to refresh the display and enable Esc and clicks on a
cancel button, what I've been using is:
- (BOOL) updateAndCheckIfCancelled {
NSEvent *event;
if (!progressCancelled)
while (event = [NSApp nextEventMatchingMask:NSAnyEventMask
untilDate:nil inMode:NSEventTrackingRunLoopMode dequeue:YES])
if (progressCancellable)
[NSApp sendEvent:event];
return progressCancelled;
}
called regularly through the loop, and it seems to work fine.

Prevent Asynchronous operation of beginSheetModalForWindow
Before I begin, I want to assure you that I have researched entries here on
sheets, as well as those in MacTech.com. It's reasonably probable that I
have missed some entries and so that is why I am asking for help.
I also realize that this description is very long and I *really* did try to
shorten it.
My app is a Cocoa Document based app.
I have chosen the title Prevent Asynchronous operation of
beginSheetModalForWindow because I use various calls to
beginSheetModalForWindow in many parts of my app code and in one case I need
the calls to didEndSelector to be completed *before* the code that follows
beginSheetModalForWindow is executed (see MyDocument.m below).
With Asynchronous operation, the sheet will show for a very brief moment and
continue as the Apple docs stipulate .. I want the sheet to stay down UNTIL
I click one of the buttons in the sheet.
MacTech names calls to beginSheetModalForWindow DocModalNew.
What have I tried to do, but without success:
*1)* After the call to [calculateSheet beginSheetModalForWindow:docWindow ..
etc]; within showCalculateSheet, I have used:
while (itsReturnCode == -1) // the initialized value before the call to
beginSheetModalForWindow
What happens is a never-ending loop from which I need to force-quit.
*2)* Within shouldCloseFile I have called:
while ((theReturnCode = [theSheet getReturnCode]) == -1); // same
never-ending loop results
The app's File's Owner is MyDocument
// inside my nib file I have a NSObject named FileController and
SheetController
// in MyDocument.h

The user can dismiss them in any order. What happens if sheet A displays, then sheet B displays, then the user goes back and closes sheet B? If there were a synchronous API the code would have to somehow jump down the stack to where you're waiting for A, while somehow leaving the stuff that's waiting for B live farther up the stack. This is quite simply impossible in a C-based language. Is there some reason you can't just put all of the after code in the endCalculateSheet: method?

re-factoring a category into a class instance
Comrades:
I am working on a file-handling Cocoa app that (at this point) has a
single window. We are adding a second window (really sort of a non-
modal dialog) to do some extra processing of the target files. The
interface for the new window is already built (with IB), but is not
hooked up yet.
So, the way this started was as a AppController(ExtraCategory) thing,
with the NIB file having a single controller object. I don't like
that method, because there is a lot of data and code that would need
to be replicated in the main AppController to handle the work that
the ExtraCategory does. What I would like to do is put all the
ExtraCategory stuff into its own class, but I am not sure how. My
inclination is toward making the ExtraCategory into a
NSWindowResponder, but the documentation I have read so far makes it
look like that is more intended for document-based apps, which this
is not. Also, I don't quite see (looking at some example code) how an
extra controller is instantiated by the main app controller.
A simplified example of the current code
@interface AppController {
NSString* srcDir; // the original stuff
NSString destDir; // original
// there is a bunch more
NSString* srcDirForExtraCategory; // needed for new window/dialog/
category
NSString destDirForExtraCategory; // needed for new
// more stuff needed here
}
-(void)setSrc; // implemented in the .m file, of course
-(void)setDest;
@end
and in AppController(ExtraCtegory)
@interface AppController(ExtraCategory)
-(void)setSrcForExtraCategory; // special handling
-(void)setDestForExtraCategory; // special handling
@end
It seems funky to me that I can declare extra functions for the
ExtraCategory, but I can't add member data. I understand there is a
difference between the class/subclass and the class/category
paradigms. I guess what I am trying to do is turn this new window
category into a standalone class, instantiate it (in the NIB, I
suppose), and control its availability from the original main app
controller instance.
Any advice?

There's no limitation of NSWindowController being only available or

You can instantiate it in the nib with IB or in code. I usually
instantiate it in code and have it load the nib and be the file's owner.

Re: Prevent Asynchronous operation of beginSheetModalForWindow
Hi John,
While I understand to some extent why you've done it this way, you've
also managed to tie yourself in knots here. Sheets are slightly more
complex than running an old-school modal dialog inline but they are
not as complicated as you seem to have made them!
The basic idea is that you have two pieces of code - one that triggers
the sheet, and another that responds to it when the user closes it.
You don't normally need anything more, though it may make sense to
factor code into a controller object which can ease its re-use (but is
not essential). You put all your code that runs after the dialog has
completed in the completion routine.
One important thing to note is that you do not *ever* run a loop like:
while( returnCode == -1 ){ ... }
that's just crazy talk ;-) Don't attempt to somehow stall the main
event loop until the sheet has finished - that will never work and
sheets aren't designed to work that way.
Here's what I typically do, this would be code in a window controller
dedicated to this sheet (warning - typed into Mail):
- (void)startSheetOnParent:(NSWindow*) parentWindow
{
/* set up the initial state of the sheet dialog here */
[NSApp beginSheet:[self window] modalForWindow:parentWindow
modalDelegate:self
didEndSelector:@selector(sheetDidEnd:returnCode:contextInfo:)
contextInfo:kSomeContextIdentifier];
}
- (void) sheetDidEnd:(NSWindow*) sheet returnCode:(int) returnCode
contextInfo:(void*) contextInfo
{
[sheet orderOut:nil]; // close the sheet
if ( returnCode == NSOKButton )
{
/* process the result of the sheet here.
If this method is shared with other sheets, you can use the
contextInfo to
disambiguate the sheet.
At this point just run the code that follows the sheet, or trigger
it using a notification perhaps
*/
}
}
That's all you need. If your sheet has controls that interact with
each other or external information, the 'modalDelegate' is the object
that will handle that - again, it will be the sheet's controller.
If your calling code currently is arranged in such a way that it
appears to you *necessary* to do something like:
- (void) doStuff
{
[mySheetController startSheetOnParent:[self windowForSheet]];
while( sheetNotDone ){} // spin hopelessly waiting for the sheet to
finish - it never will because you've entered an infinite loop
if ( sheetResult == NSOKButton )
{
/* continue doing stuff */
}
}
then you need to refactor your code so that the 'keep doing stuff'
part can be called directly from the sheet ended callback.
One thing that should be clear but maybe isn't is that the term
'asynchronous' is a little misleading - the sheet is still being run
on the same thread as the code that called it, so entering a while()
loop waiting for the sheet to finish cannot possibly work - that loop
will block the main thread so the sheet cannot continue to function,
and there's nothing that could cause the loop to terminate. There is
already a loop running that accomplishes this - the main event loop.

Graham

MacTech names calls to beginSheetModalForWindow DocModalNew.
What have I tried to do, but without success:

etc]; within showCalculateSheet, I have used:
while (itsReturnCode == -1) // the initialized value before the

Re: NSSlider responding to superview's drawRect
I don't think it's worth attempting. I *think* that gradients are cached in some way so trying to recalculate the gradient to span the update rect correctly is: a) going to need a fair bit of work to calculate and b) not allow caching to work efficiently. In any case, pixels that are clipped out shouldn't be being drawn anyway, so the performance gain is likely to be miniscule. G.

Cocoa PDE validation

On 10.5, this is easy to implement with the shouldPrint method, but I need to replicate this behaviour on Tiger as well. The saveValuesAndReturnError does not help, because this is called when switching between presets. So if they have not input the passphrase and try to switch presets the user will get an error alert for doing nothing wrong.

Re: launching standard apps with NSTask
LaunchServices or NSWorkspace (which uses LS) is still probably your best option, as NSTask is not really designed to deal with GUI apps. To terminate the app, you can send a quit apple event or use applescript. This has come up recently, so search the list archives.

Re: A simple doubt about array
If you do want to make use of some of the nice features of NSArray
that C arrays don't have, it is trivial to add a category to NSArray
that makes object retrieval easier. See http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/Articles/chapter_4_section_1.html
An example implementation might look something like this (not tested,
and no type checking which you should probably do):
@implementation NSArray (PuzzleBoardAdditions)
- (id)objectAtRow:(NSUInteger)row column:(NSUInteger)column
{
return [(NSArray *)[self objectAtIndex:row] objectAtIndex:column];
}
@end
and (after importing the category interface), you can call it with one
clean line like [array objectAtRow:0 column:0]

Re: launching standard apps with NSTask
Ok Thanks, will check it out... Memo (Mehmet S. Akten) www.memo.tv [EMAIL PROTECTED] On 11 Jun 2008, at 01:20, Adam Leonard wrote: LaunchServices or NSWorkspace (which uses LS) is still probably your best option, as NSTask is not really designed to deal with GUI apps. To terminate the app, you can send a quit apple event or use applescript. This has come up recently, so search the list archives. To detect when the user terminates the application, you can also use NSWorkspace.

I would like to have that level of control (just terminate, and detect if user close it) - which is why I was opting for NSTask - but actually I'm not having any luck with that either! (if I put the path to the .app I get a permission error, if I put the path to the file in contents/macos it doesn't work!). is there anything else I can do? Memo (Mehmet S.

Re: Spotlight sources w/o actual files?

The problem is the metadata itself is probably hundreds of gigabytes, if not terabytes in size, so it would be impossible to have mdimporter index fake files. If the _meta_data is really that large, then this is sort of an insane thing to try to do. It means that at least that much data will have to be accessed by Spotlight on the initial indexing pass, and similarly that much data will need to be stored in Spotlight's indexes. How much network traffic will this involve? How much CPU to run your importer on all of this data? How much disk space to store the metadata into Spotlight's index? This is just plain abuse of Spotlight. Regards, Ken ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: re-factoring a category into a class instance
Ooops, saw that go by and spaced out fixing it. I am just beginning with Cocoa, and the framework names are not that familiar yet. Thanks for the advice, Brian, especially the part about instantiating my controller in code. I figured it couldn't be too hard, but a little nudge in the right direction is welcome.

All this tells me is that somebody is trying to draw the table after the controller has been released and the window has been hidden if not released. I pretty much knew that already. In your windowWillClose method, set the tableview datasource and delegate to nil, so it stops messaging your controller. This is a good habit to get into with datasource/delegate objects.

Issue with displaying URI prefixes on child elements using NSXML
Hey everybody, I've got an issue that I can't figure out.
If I'm using this code:
NSString *XMLForDisplay {
NSXMLElement *root = [NSXMLNode elementWithName:@root];
[root addNamespace:[NSXMLNode namespaceWithName:@a stringValue:@http://www.tempurl.com
]];
NSXMLElement *child = [NSXMLNode elementWithName:@child URI:@http://www.tempurl.com
];
[child addChild:[NSXMLNode textWithStringValue:@myText]];
[root addChild:child];
return [root XMLStringWithOptions:NSXMLNodePrettyPrint];
}
I believe it should be outputting this text:
root xmlns:a=http://www.tempurl.com;
a:childmyText/a:child
/root
However, instead it outputs this text (note the lack of prefix on the
child):
root xmlns:a=http://www.tempurl.com;
childmyText/child
/root
This is an issue, because I need that a: prefix.
The documentation for elementWithName:URI: states it's equivalent to
URI:name/URI:name, which is exactly what I want, except that I
can't get it to display that way.
Thanks for your time.

Sure, I can easily implement piecemeal work using a timer. That's not
quite the same as I was asking. I was wondering if I could do
something like:
while( notFinished )
{
/* do some work */
letTheEventLoopRunABit();
}
This was a pretty common idiom in the pre-OS X days, though of course
one must bear in mind what the stack looks like when the event loop is
allowed to run. It ain't pretty ;-)
That said - No, it is not considered to be a good approach. It's

Yep, seems to be the way to go. In this case it was an easy change to
allow the work to run on a separate thread. I guess the only thing
that scares me about threads are the sheer number of classes that are
not considered thread-safe, and so calling one accidentally from
another thread.
cheers, Graham
