I have a structure I'm trying to write as an xml plist. The structure is an 
array of dictionaries, each dictionary contains a string "catname" and another 
array of dictionaries, "items". The second level of dictionaries consist of two 
strings each, "id" and "name".

Example:

(gdb) po catList
(
{
catname = "Legends & Inset Maps";
items = {(
{
id = "7CBC1609-ADFB-4CA9-A748-CABE9076842F";
name = "World - eastern hemisphere";
},
{
id = "402DEB4D-8C2E-4F4D-9151-E6BA01D194E7";
name = "World - western hemisphere";
},
{
id = "6500292B-FDE1-45B7-AFD9-8A0136B25717";
name = "Legend 4";
},
{
id = "CC96E4F2-1B20-4496-8962-15B617B3FAF9";
name = "Legend 2";
},
 ... hundreds of similar entries omitted...
)};
},
{
catname = "DrawKit Defaults";
items = {(
{
id = "6B1A0430-204A-4012-B96D-A4EE9890A2A3";
name = "Basic Track";
},
{
id = "1DFD6D8A-6C8B-4E4B-9186-90F64654F79F";
name = Basic;
},
{
id = "326CF635-7863-42C6-900D-CFFC7D57505E";
name = "Helvetica 18.0pt";
}
)};
}
)

When I submit this array to the serialization method:

NSData* data = [NSPropertyListSerialization 
dataFromPropertyList:catList format:NSPropertyListXMLFormat_v1_0 
errorDescription:&errDesc];

(I know this is deprecated from 10.6 forward but I need to support 10.5 for now)
I get the error:

 "Property list invalid for format"

Since I'm only using arrays, dictionaries and strings, that should be a valid 
plist, shouldn't it? I've missed something, but what?

I'm also wondering why some strings appear quoted and others are not when I 
dump the structure in gdb, and whether that's significant.

Don't know, but maybe 'id' is reserved.

I seem to recall a similar issue with archiving strings that were "NULL" or 
"nil" or something.

Well, I just tried changing that to something else and I get the same problem. 
I also tried using NSPropertyListBinaryFormat_v1_0 and I still get the same 
error.

Re: NSPropertyListSerialization error with apparently OK data

2010-02-18 Thread Jean-Daniel Dupas


Don't think so, archiving is not serialization and it's just a dump of the 
object in XML/binary format, so you can't have reserved keyword.


The plist look definitively OK. (it's even possible to import it in Plist 
Editor as a text formatted plist if you remove the extra '{' '}' enclosing the 
inner array).

I'm almost sure it will not help, but you may try the 10.6 function which 
returns an NSError. Maybe the NSError is more informative than the returned 
error string.

And you can also try with subset of the list to determine if a specific entry 
in your list is the culprit.

OK, seems likely to be the problem, unless it's the sheer size. The list has 
several thousand entries, but I haven't read of any restrictions anywhere.

NSTableViewDataSource Protocol

Hi,

I am writing an app that needs to be able to target 10.5 at least and hopefully 
10.4, but I have just found that the way that table views are handled has 
changed - does anyone have a link to some documentation for the old way to do 
things?

Many thanks,

Mikey___

Re : Proper way to initialize application support file

2010-02-18 Thread Peter Hudson


I'm getting confused.

It seems that any files that are 'essential to the running of the  
app'  are placed in the bundle.


It also seems that any files that are 'essential to the running of the  
app',  if they are in the bundle,  must not be modified.


The type of files which I put in the bundle are both essential for the  
app to run and need ( from time to time ) to be modified.


Copying from bundle to elsewhere and then modifying the copies is not  
a runner - as the user would want their format data back as it was  
when they restart the app.

Re: NSTableViewDataSource Protocol

Weird, cos when I change the Active SDK in Xcode to 10.5 I get the following 
error:

cannot find protocol declaration for 'NSTableViewDataSource'

And the docs here: 

http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Reference/ApplicationKit/Protocols/NSTableDataSource_Protocol/Reference/Reference.html

Suggest that it is available to 10.6 and later

Any idea what I might be doing wrong?

Think of it this way. Files you open directly from your bundle should be 
considered READ ONLY. Therefore if you want to use a modified version, you have 
to copy them elsewhere so that they can be read/write, and that somewhere else 
is usually ~/Library/Application Support//

I don't see a conflict between this and your users getting the modified 
versions when they rerun the app. The modified files are still right where you 
left them. Your app will need to perform some sort of merge between the 
unmodified bundle version and any modified versions it finds in app support, so 
that the total set of files the user is working with is the latest. It can be a 
lot of work - in fact I'm working on something like that right now.

If you mean they need up-to-date files if the app is moved to another machine 
or installed for another user, there's not a lot you can do about that except 
instruct them to take the modified files with them. Most apps would not be 
designed that way.

In 10.6, NSTableViewDataSource became a formal protocol, where previously it 
was an informal one. While the docs are strictly correct, they're a bit 
misleading since the methods of the protocol have been available since 10.0

If your datasource is declared thus:

@interface MyDS 

...

@end

you need to remove the angle bracket part for 10.5

All that's changed is it's gone from an informal protocol:

@interface NSObject (NSTableViewDataSource)
...
@end

to a formal one:

@protocol NSTableViewDataSource

This does not to me sound like a loose definition, and in my opinion this is 
exactly the kind of circumstance in which you should use the Application 
Support folder. If that data is specific to a user, then put it in 
~/Application Support/appInfo. You can (and should) get the path for such 
directories  from NSPathUtilities:

For the system's Application Folder:
NSArray *paths = 
NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, 
NSSystemDomainMask, YES); 
s = [paths objectAtIndex:0];

For the user's Application Folder:
NSArray *paths = 
NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, 
NSUserDomainMask, YES); 
s = [paths objectAtIndex:0];

NSSearchPathForDirectoriesInDomains is described in Foundation Functions 
Reference. Values for the parameters (NSSearchPathDirectory and 
NSSearchPathDomainMask) are described in  the Foundation Data Types Reference. 
Or just look at the enums declared in NSPathUtilities.h

Yes, do what I told you, remove the NSTableViewDataSource from the protocol 
list, like this:

I started out this way to avoid exactly the problem you get from  
requiring users to move critical files around.  Most of our users  
are not comfortable with computers, let alone moving files  
around !   Add in the problem of making sure they read the right  
pages of the manual ( if they can find it ) and then do this through  
language barriers ... ( we run in many languages ) ..

modified versions when they rerun the app. The modified files are  
still right where you left them. Your app will need to perform some  
sort of merge between the unmodified bundle version and any  
modified versions it finds in app support, so that the total set of  
files the user is working with is the latest. It can be a lot of  
work - in fact I'm working on something like that right now.

If you mean they need up-to-date files if the app is moved to  
another machine or installed for another user, there's not a lot  
you can do about that except instruct them to take the modified  
files with them. Most apps would not be designed that way.

I'm not suggesting they do move the files around. Your app can move them around 
to do what it needs to do, and the user is none the wiser. They need not care 
if a resource they are using comes from the bundle or from app support, it Just 
Works, right?

Since you haven't really defined what these files are or how they're used, I 
can only give general and vague suggestions. My app does something apparently 
similar - we supply a default set of content in the form of graphics and these 
come in the bundle. On first startup we copy the file to app support so that 
the user can customise and add to the available graphics. Currently this is 
just one file, so "the latest" is always the one in app support, but actually 
this is a drawback on a number of levels so I'm working on splitting this out 
into one file per graphic, and the app will combine the bundle (read only) 
files with the app support (read/write) files to present a unified set to the 
user. They don't care where they come from, they just use them.

If the same app is copied/installed elsewhere, all the new installation gets is 
the original bundle set, not any new ones the other user made. That's 
completely normal and I would say expected behaviour.

The simple fact is that you cannot reliably update your app as it runs by 
writing files to its bundle. So however you need it to work, this option is not 
available.

super call in the middle of a block of code ..

2010-02-18 Thread Roland King

I have this piece of code in my UITableViewController subclass (that is also my 
tableview delegate)

-(void)setEditing:(BOOL)editing animated:(BOOL)animated
{
if( editing )
preEditPath = [ [ [ self tableView ] indexPathForSelectedRow ] 
retain ];

[ super setEditing:editing animated:animated ];

if( !editing )
{
[ [ self tableView ] selectRowAtIndexPath:preEditPath 
animated:YES scrollPosition:UITableViewScrollPositionNone ];
[ preEditPath release ];
preEditPath = nil;
}
}

The object here is to catch the current selection on the tableview when the 
table goes into edit mode (because when it does, the selection is nil'ed with 
no delegate call)  and then restore it when the table comes out of edit mode. 
In the meantime I'm using the delegate calls which do exist to deal with the 
case where the selected row is moved or deleted so I restore the right thing. 

The super call is in the middle of the block because I've observed that it's 
that super call which removes the selection whether you are entering or exiting 
edit mode, so if I call it right at the start of the block, the selection is 
nil'ed before I cache it, if I call super at the end of the block, the super 
call deselects the selection I just put back. 

But having a super call in the middle of an overriden method seems wrong to me, 
and a bit fragile, and it relies on the observation that that's where the 
selection is nil'ed. Is this unusual, totally wrong or ok?

 So, does anyone know where this 64 pixels limit is coming from?

Perhaps, but the goal is to avoid Carbon stuff. But, if this were possible, I 
would be interested.

In any case, I have filed a bug report on this - rdar://7662356.

Btw, the reason why this is important is that the window is a resizable NSPanel 
which contains several tool buttons which the user needs to be able to arrange 
in a single column.

The width of the buttons is not large enough so a single column of them would 
cause the panel to be wide enough to show the zoom button, so the zoom button 
is hidden - which is common among such interfaces.

If anyone is interested, a sample application demonstrating the problem can be 
found at - http://ericgorr.net/cocoadev/WindowWillResize.zip

The other odd thing I noticed is that once one gets to < 64 pixels, calls to 
windowWillResize:toSize: becomes jumpy. It only seems to be called if the 
cursor is moving to the left "fast enough" to trigger the call. Moving by 
single pixels to the left will not cause windowWillResize:toSize: to be called.

I don't know your design, but if you use an HUD-style NSPanel, that limitation 
doesn't apply. Would that be an option? It would certainly be the easiest way 
out.

Interesting.  I had not considered that before. Thank you!

The real question is then how to handle another feature required of the 
NSPanel's which is to window shade them. Currently, the minimize button has 
been overridden to provide this behavior. However, if it were easy to get some 
other kind of window shade button or indicator into the title bar (and, I'm 
guessing that it is), this is certainly an option.

I will have to consider it some more to determine whether or not it really fits.

Re: super call in the middle of a block of code ..

This seems fine to me. Generally, when subclassing, the contract is that you 
must call super - there is nothing said about where in your method you do so.

"Formal Protocol Adoption" says:

If you need to target Leopard or Tiger with the same sources, you should
conditionally declare empty protocols, or else the compiler will
complain about missing protocols declarations. For example:
#if MAC_OS_X_VERSION_10_6 > MAC_OS_X_VERSION_MAX_ALLOWED
@protocol NSConnectionDelegate  @end
#endif

There should be a free event at some point; make sure you check the option to 
keep track of all retain/releases -- look for the last release. That callstack 
is the last person who "owned" the object had it, and released it. Based on 
that information, you need to some how ensure it is retained longer than that 
time period.

 If you have an NSCell subclass which adds iVars, you must implement 
 -copyWithZone: to do correct memory management.
 
 Your -copyWithZone: needs to work correctly within the bounds of the 
 object ownership rules.
 
 If you have an object iVar which shouldn’t be copied, but is still an 
 owned reference, then you can (and must) retain it instead in the copy.
 
 (You should do this for all cells with iVars, not just ones with object 
 iVars, so that your subclass will behave correctly in the future even if 
 NSCell doesn’t implement its behavior using NSCopyObject.)

Thanks, Jonathan.  Using Matt Gemmel's idea of making an attached window, I 
wrote a class that makes a fat arrow with a blue gradient that looks like the 
one you get when you click a menu item after searching in Help.

Now, I'd like it to be animated, like Apple's fat blue Help arrow, moving 
slowly in a little circle.  In Matt's code, he moves the attached window by 
re-creating it.  I could do this brute force, offsetting the frame with 
x=cos(wt) and y=sin(wt).

In the Core Animation Programming Guide > Animatable Properties, it says that 
'position' can be animated, and this has the effect of animating the frame.  
I've never used Core Animation.  Is Core Animation the tool for this job or 
should I use my brute force? 

Thanks,

Jerry Krinock

I shake an authentication window on failure using the following CA code. 

NSWindowController subclass

// shake it
[[self window] setAnimations:[NSDictionary dictionaryWithObject:[self 
shakeAnimation:[[self window] frame]] forKey:@"frameOrigin"]];
[[[self window] animator] setFrameOrigin:[[self window] frame].origin];


/*

{
CAKeyframeAnimation *shakeAnimation = [CAKeyframeAnimation animation];

CGMutablePathRef shakePath = CGPathCreateMutable();
CGPathMoveToPoint(shakePath, NULL, NSMinX(frame), NSMinY(frame));
int idx;
for (idx = 0; idx < numberOfShakes; ++idx)
{
CGPathAddLineToPoint(shakePath, NULL, NSMinX(frame) - 
frame.size.width * vigourOfShake, NSMinY(frame));
CGPathAddLineToPoint(shakePath, NULL, NSMinX(frame) +

Determine smallest height of vertical scrollbar

Other then creating a dummy NSScoller and incrementally decreasing it's height 
until usableParts returns 0, is there any easy way to determine what the 
minimum height of a vertical scrollbar should be so that usableParts will not 
return NSNoScrollerParts?

What I need to be able to do is limit the height of my window based, in part, 
on whether or not a vertical scrollbar will have usable parts.

HEllo Corbin, 
It seem its fixed, I didn't realize an ivar in the Custom NSCell, I forgot I 
put it there thinking in using it to hold the name of the user and be able to 
sort the table, which right now I can;t tell how to do it, I took out that 
ivar, and it hasn't crash so far.. still Im gonna keep trying to make it crash 
and if it happens, then I will do what you suggested.

Thanks for the help and the blog link.. I learned a something else I wished to

 Hello Jim
 HMM digging more into the problem.. definitely it seems because Im not 
 copying properly the NSManagedObject Paul Robinson says in one old post:
 
 "The short answer is that you need to override the setObjectValue: method 
 (which tries to copy your uncopyable NSManagedObject) in your custom 
 NSCell to convert your NSManagedObject into an NSValue (which is 
 copyable)."
 
 
 And taking what you said,  so if my User ManagedObject returns me the 
 NSDictionary with the key-value of its attributes, then in the cell I must 
 set it as an ivar within the method setObjectValue, then implement the 
 copyWithZone and return the copy of it isn't it? right now I don't have 
 any ivar in my custom cell.. sooo .  := :S.

How do I get keyboard events in an NSStatusWindowLevel window while my application is not frontmost?

2010-02-18 Thread Daniel Káčer

After creating a translucent NSPanel and I want to get keyboard events  
in this window. It seems that there are only keyboard events when my  
application is the active application while I want keyboard events  
even when my application isn't active but the window is visible.


Basically I want behavior like that provided by the Quicksilver  
application.


Does anybody have any hints on how to do this?

Ah! So it was the extra ivar in your custom cell. That's was my initial guess. 
the extra ivar is okay; you just have to retain or copy it in the cell's 
implementation of -copyWithZone:

If you want to handle a particular keystroke (like Quicksilver's Ctrl- 
Space) no matter what app is active, define a system hot-key. There is  
sample code showing how to do this, but I don't know an exact name or  
URL.


Once your hot key has triggered, call [NSApp  
activateIgnoringOtherApps: YES] and [myWindow makeKeyAndOrderFront:  
nil], so your window will have focus and will receive typing.

Hillegass printing challenge

2010-02-18 Thread Michael de Haan

Hi all,
May I ask about an issue I am having adding page numbers to a print out.
I implemented the following method:


- (void)drawPageBorderWithSize:(NSSize)borderSize
{
   // NSPrintOperation *po = [NSPrintOperation currentOperation];
//NSPrintInfo *pi = [po printInfo];

NSRect currentFrame = [self frame]; 
NSRect newFrame= NSMakeRect(0, 0, borderSize.width, borderSize.height);
[self setFrame:newFrame];

NSFont *f = [attributes objectForKey:NSFontAttributeName];
float capHeigth = [ f capHeight];
NSString *string = [ NSString stringWithFormat:@"Page %d", currentPage + 1];
float stringX = (borderSize.width - (float)[string length])/2.0;
[self lockFocus];
[string drawAtPoint:NSMakePoint(stringX, borderSize.height - (1.7 * 
capHeigth))
withAttributes:attributes];
[self unlockFocus];
[self setFrame:currentFrame];
}


A while ago, there were questions to the list about printInfo "margin" calls. 
At that time, it appears  the consensus was that these calls are buggy. I think 
they still are, as my code showed that the margins returned bore no 
relationship to the margins set in page Setup.  As a workaround, I used the 
above approach. What do others do to deduce the user's margin settingsor 
it's possible that I am missing something else.
Thanks in advance.___

Implement the NSWindow delegate method - (NSSize)windowWillResize:(NSWindow 
*)sender toSize:(NSSize)frameSize. In that method, return an NSSize that has 
the right aspect ratio.

Good luck,

You could check out NSWindow's setAspectRatio or setContentAspectRatio.

These are discussed in NSWindow's programming guide.

NSTableView with PopUpButtonCell column with different content per row

2010-02-18 Thread Sean McBride

Hi all,

I'm looking for some pointers on how to have a TableView where one
column uses a PopUpButtonCell who's contents need to be different for
different rows.

A contrived example:

OS Name OS Version


So in the 'OS Version' column, I want the popup's contents to be either
one list or another list depending on 'OS Name' of any given row.

Any suggestions?

Thanks,

Hook yourself up as the delegate of the column's popup button cell's
menu, and implement -menuNeedsUpdate: to populate the menu with the
correct set of items depending on the selected item.

Aside from what Kyle suggested (adjusting the menu dynamically "in" the 
interface), you could simply have your window controller provide an array 
property with version strings for the current OS (along with a KVO dependency 
to keep the property in sync with the current OS), and bind the popup content 
to that array.

However, I'd suggest that perhaps you're asking the wrong question -- there 
might be a deeper data model design issue.

Presumably your data model would have an "OS" property (maybe an integer 
constant, maybe a string, maybe an object) and a "version" property (ditto). It 
seems to me it's up to the data model to specify which are the valid versions 
for each OS value, otherwise how can the data model validate itself? The 
consequence would be that it's the data model's responsibility to supply the 
arrays [of integers/strings/objects] that ultimately allow you to populate your 
popups appropriately. It would then be up to the window controller (or perhaps 
a view) to transform the pure data model information into the properties that 
the interface needs for binding purposes.

Without that, the danger is that your data model depends for its correctness on 
its internal rules being re-implemented correctly in the view portion of your 
design. That would likely be an abuse of the MVC pattern.

FWIW.

Quincey's answer is excellent, and abstract.  Let me give you a concrete 
example from one of my projects.  Presumably your table is bound to an array 
controller whose contentSet or contentArray is bound to a collection of Foo 
objects in your data model.

Table Column Bindings for "OS Version" column:

Content:
  Bind to: FooArrayController
  Controller Key: arrangedObjects
  Model Key Path: osVersionChoices

Content Values:
  Bind to: FooArrayController
  Controller Key: arrangedObjects
  Model Key Path: osVersionChoices.osVersionDisplayName

Selected Object:
  Bind to: FooArrayController
  Controller Key: arrangedObjects
  Model Key Path: osVersion

In your data model,

@interface Foo {
}

@property (retain) NSString* osVersion ; // Could also be NSNumber

/* Returns an array of NSStrings (or NSNumbers) */
- (NSArray*)osVersionChoices ;

...

@end

And finally, and I forgot who it was who gave me this invaluable tip, you 
implement a category on NSString (or NSNumber) which defines 
-osVersionDisplayName.  You can do your localization or transforming in here.  
I've never been able to get a Value Transformer to work in an NSTableColumn 
binding.  But the category works every time.

Note that -osVersionChoices and of course -osVersionDisplay name are readonly.  
No problem.  If you table is not editable, -osVersion can be readonly too.

Hi Michael,

I'm not sure that they're buggy, it's just they don't return what you think 
they do, or what their name appears to imply. I added the following to 
NSPrintInfo as a category so I can get the actual paper margins set in Page 
Setup, it might come in handy for you too.



enum
{
PrintInfoTopMarginIndex = 0,
PrintInfoLeftMarginIndex= 1,
PrintInfoBottomMarginIndex  = 2,
PrintInfoRightMarginIndex   = 3
};


@implementation NSPrintInfo (PaperMargins)


- (NSArray*)paperMargins
{
PMPageFormatformat = (PMPageFormat)[self PMPageFormat];
PMPaper paper;
OSStatuserr = PMGetPageFormatPaper( format, &paper );

if( err == noErr )
{
PMPaperMargins  margins;
err = PMPaperGetMargins( paper, &margins );

if( err == noErr )
{
NSMutableArray* array = [NSMutableArray array];
[array addObject:[NSNumber 
numberWithDouble:margins.top]];
[array addObject:[NSNumber 
numberWithDouble:margins.left]];
[array addObject:[NSNumber 
numberWithDouble:margins.bottom]];
[array addObject:[NSNumber 
numberWithDouble:margins.right]];
 
return array;
}
}

return nil;
}



- (double)  topPaperMargin
{
return [[[self paperMargins] objectAtIndex:PrintInfoTopMarginIndex] 
doubleValue];
}



- (double)  leftPaperMargin
{
return [[[self paperMargins] objectAtIndex:PrintInfoLeftMarginIndex] 
doubleValue];
}



- (double)  bottomPaperMargin
{
return [[[self paperMargins] objectAtIndex:PrintInfoBottomMarginIndex] 
doubleValue];
}



- (double)  rightPaperMargin
{
return [[[self paperMargins] objectAtIndex:PrintInfoRightMarginIndex] 
doubleValue];
}


@end

NSTableColumn's 'fontSize' Binding: Just Doesn't Work?

I know how to control the font size in a table -- the hard way -- by
subclassing NSTableColumn and overriding -dataCellForRow. Hoping for an easy
way, I noticed that NSTableView has a 'fontSize' binding...

fontSize. An integer value that determines the size, in points, of the font
used to display the NSTableView. If fontSize is bound, the font binding is
disabled.

Whoopee! So, in Interface Builder, I leave 'font' unbound, and bind thus:

fontSize
Bind to: Shared User Defaults Controller
Controller Key: values
Model Key Path: myFontSize

myFontSize is a key in my user defaults.

Result: It just doesn't work. Silently ignores the value in user defaults,
both upon awaking and when it is changed.

This was reported also by Chris Miner two years ago:

http://www.cocoabuilder.com/archive/cocoa/197369-under-what-circumstances-does-the-fontsize-binding-of-nstableview-have-an-effect.html?q=NSTableView+fontSize+binding#197369

I understand that NSUserDefaults bindings do not issue an error if Model Key
Path does not exist. But I checked the spelling three times.

Has anyone ever seen this binding work?

Use of NSView enterFullScreenMode withOptions causes warning about deprecated CPSSetForegroundOperationState

2010-02-18 Thread Shayne Wissler

Hello,

In my application I have the following call:

  [self enterFullScreenMode:[NSScreen mainScreen] withOptions:0];

This function is documented here, and does not appear to be deprecated:

http://developer.apple.com/mac/library/documentation/Cocoa/Reference/ApplicationKit/Classes/NSView_Class/Reference/NSView.html#//apple_ref/occ/instm/NSView/enterFullScreenMode:withOptions:

And yet I am getting the following message right after making this call:

myApp[11220]: CPSSetForegroundOperationState(): This call is
deprecated and should not be called anymore.

I am using the latest released version of OSX, 10.5.8. Any tips would
be appreciated.


Thanks,

Why do that, when you could just use the willDisplayCell delegate method?

That poster seemed to say that the font was nil. If this is the case, font size 
could not produce defined results. What happens when you bind "font" as well?

Re: NSPredicate regex

2010-02-18 Thread martin halter

hello list 

I'd like to check a bunch of Strings if they contain the word "cache". The 
strings are actually paths and I check the last path component. I tried to use 
CoreText to detect words, but the API was a bit overwhelming. So I tried 
NSPredicate which worked like a charm. It detects the word as of word 
boundaries are not characters (numbers, space, dash and everything else). 

{
NSString *regex = @"(?:.*[\\s\\W0-9])*cache(?:[\\s\\W0-9].*)*";
NSPredicate * cacheStringRegex = [NSPredicate predicateWithFormat:@"SELF 
MATCHES %@", regex];
...

NSURL url; // assume this exists, comes from a directory enumerator
if ( [cacheStringRegex evaluateWithObject:[url lastPathComponent]] ) {
NSLog(@"found cache directory");
}
}

sadly, there is an error in the regex and i cannot find it. I had three strings 
where the CPU went to 100% and the app did not recover. here the three strings 
(yes, those are directory names outside of NSCachesDirectory, i was surprised 
too :-)

Help with creating CustomViews

2010-02-18 Thread Jean-Henri Duteau

Hi all,

I'm a newcomer when it comes to Cocoa development.  I have some good books and 
they discuss the possibility of CustomViews but the views they create aren't 
the type that I'm interested.  I've scoured the web and haven't found exactly 
the help I need and I've tried the trial-and-error method and it hasn't worked.

What I'm trying to do is the following:
-I have a number of model objects, different instances of the same class.
-I want to create a CustomView that would enable the display of these objects.
-The CustomView is defined in its own NIB file.  It consists of a bunch of 
NSTextField objects laid out in NSBox.
-I then want to use that CustomView all over the place. :)  But for starters, 
I'm trying to create a window with 10 instances of my CustomView.
-I want to drop the CustomView in other NIB files and set up the 
actions/outlets/etc.

The path that I took that seemed to give the best promise was:
I created a CustomViewController (subclassing NSViewController)
In MyDocument.init, I init the CustomViewController with my CustomView NIB file.
In MyDocument.windowControllerDidLoadNib, I call viewController.view setFrame: 
and then windowController.window.contentView addSubView.

That manages to get my CustomView to show up in the document's window.  But 
that was done programatically and not in IB.

Then I looked at the DragAround sample code on the Apple site.  This seemed to 
be exactly give tips for exactly what I wanted, except that the DragAroundView 
draws itself, there is no NIB file for the view.

If someone can point me to some sample code, that would be great.  In the 
meantime, I'll keep trying.

Re: Appropriate -setWantsLayer: timing

2010-02-18 Thread Simon Wolf

Hi Keith,

In addition to David's reply, a small tip is that you can also get things 
working if you call setWantsLayer: and then follow it by assigning a layer:

[self setWantsLayer:YES];
[self setLayer:[CALayer layer]];

Otherwise the layer is added at some undetermined future point which may not 
(in my experience ever) be in the current run loop.

Hi Keith,

Whilst I was putting together something recently (it's on my blog is you want 
to see the code) but ended up with the ability to add the layers in 
-awakeFromNib because the view will always be defined in advance.

However I essentially ended up having to call -setWantsLayer: on my view and on 
the parent view as two calls because the parent view didn't always seem to pass 
the layer-backing on down to my view.

I thought that adding layer-backing in -initWithFrame: worked (you might need 
to add a layer at the same time) and I think you'll get away with calling it in 
both -initWithFrame: and in -awakeFromNib without any problems. At the very 
least you could check in -awakeFromNib to see if the view is already 
layer-backed and only call setWantsLayer: if it is not.

Real-Time Validation in a NSTextField.

2010-02-18 Thread Abhinay Kartik Reddyreddy

I have a NSTextField which should only accept numbers in a certain range say 
(-72000.00 to 72000.00). 

I tried using NSFormatter whihc worked partially. when i hit any alphabet 
character on the keyboard, the value in the NSTextField stays numeric but the 
cursor moves forward which is not desired. Heres how i set the formatter.

NSNumberFormatter* numFormatr = [[NSNumberFormatter alloc] init];
[numFormatr setFormatterBehavior:NSNumberFormatterBehaviorDefault];
[numFormatr setNumberStyle:NSNumberFormatterDecimalStyle];
[numFormatr setMinimumFractionDigits:2];
[mtextfield setFormatter:numFormatr];

Am i doing something wrong here..?? 

I tried an alternate approach using the delegate method controlTextDidChange:  
I ended up with the same problem as above. cursor position is incremented when 
an invalid character is typed.

- (void) controlTextDidChange:(NSNotification *)obj
{
// get the string value from the textfield
// eliminate invalid characters in the string
// set the result string as stringvalue of textfield
}

I was wondering if  there is any alternative / better approach for validating 
text in a textfield??

Thanks,
Abhinay.

close: before NSWindowWillCloseNotification

2010-02-18 Thread Charles Burnstagger

Hi all,

I have a typical window/controller on OS X 10.6.2.

When I click the window's close box, my window controller receives the close: 
message before it recevies the windowWillCloseNotification. This seems to be 
backwards in sequence to me. Any ideas why this happens and how to avoid it?

I need to recieve the notification *before* I receive close: since I want to do 
some stuff before the window goes away.

Thanks,

Chuck

This is incorrect.

If you want a layer-hosting view (rather than a layer-backed view) you must do 
this in the reverse order. setLayer: and then setWantsLayer:

Panning's just changing the x/y offset, while zooming changes the x/y scale. So 
figure out a position to start and end, and interpolate between them based on 
the time elapsed.

fract = (now - startTime) / totalTime
x = x0 + fract*(x1-x0)
y = y0 + fract*(y1-y0)
scale = scale0 + fract*(scale1-scale0)

then construct a transform based on x,y and scale, and set that.

What kind of stuff? The window still exists when you get the windowWillClose 
notification, so you can safely call into it or your views.

If you're talking about interacting with the user (like confirming the close), 
you should implement the -windowShouldClose: delegate method. This gets called 
earlier, before the -close call, and by returning NO from it you can prevent 
the close entirely.

How to detect if mouse on border of view

2010-02-18 Thread Mazen M. Abdel-Rahman

Hi All,

I was wondering if there is a straight forward away to know if the mouse is on 
the border of a view?  I know how to detect if the mouse enters a view area by 
using NSTrackingArea - but how can I tell if the mouse is on a border?  I would 
like to replicate iCal's behavior where a user can modify an event on the 
calendar by clicking on the edge of the appt. rectangle and dragging it.  

Thanks,
Mazen

The "border" of a view doesn't really exist - it's infinitely narrow.

What you really want is to detect that the mouse is inside the view but within 
a pixel or two of the edge. That is easy to work out by comparing the mouse 
point against the bounds to whatever degree of precision you want (I'd suggest 
not making it too precise, as it will be hard to hit - 4 pixels minimum is 
probably OK).
