I don't think read-only means what you think it does. It's not some  
kind of write protection in the database; it's just a characteristic  
of the in-memory object, kind of like the distinction between  
mutable and non-mutable collections in Foundation.

Why do you assume it should be called? You passed a minimum of 1

Re: FSCopyObjectASync Not Calling Callback In Cocoa

[Michael Vannorsdel]

I read over the docs for this function and not coming to the same  
conclusions.  Being an async function it should be implied the  
callback will be used if the starting function succeeded.  This is the  
whole point of async operations and the only way to get status reports  
from them besides having to poll, which defeats the purpose of async  
operations.  Also, the minimum time argument as the docs explains is  
there to limit the time between multiple calls for a "single  
stage" (ie kFSOperationStageRunning) for flood prevention and doesn't  
apply to stage changes.  Also, the presence of a  
"kFSOperationStageComplete: The file operation is complete." makes it  
pretty clear there should be a status report upon completion.


The only error here I believe, as explained by someone else, is  
forgetting to schedule the event source with the runloop for  
processing.  However after reading the docs I too am lead to believe  
(and know from experience with this function) that the callback is  
used and is called upon completion.

Re: Immediate memory release

[Paul Bailey]

The class documentation for NSAutoreleasePool notes that release is a no-op
on garbage-collected environments, and one should use drain to give the
garbage collector a hint to do its job (that's my limited understanding).
It notes that drains behaves the same as release in a memory managed
environment, so it's safe to use in both circumstances.

Basically, if there's a chance your code might be garbage-collected, use
drain.

As for new, not sure...

Cheers,

Paul

NSFormatter, NSTextfield and bindings

[Yann Disser]

I have a NSTextfield which is bound to some string-valued attribute.  
It is set to update continuously and everything works fine.


As I only want to allow the user to enter numbers, I subclassed  
NSFormatter and attached an instance to the NSTextField "formatter"  
outlet in IB.


Now my attribute gets set exactly ONCE (?) - the very first time I  
enter a valid character in the text field. I found the following with  
google: http://www.cocoabuilder.com/archive/message/cocoa/2007/6/26/185130

and it seems that this behaviour might be intentional... (?!)

How can I obtain the desired behaviour of my text field with  
continuous updates?


This is how my Formatter looks like:

@implementation StrictNumberFormatter

-(NSString*)stringForObjectValue:(id)anObject
{
  if(![anObject isKindOfClass:[NSString class]])
return nil;
  return anObject;
}

-(BOOL)getObjectValue:(id*)obj forString:(NSString*)string
  errorDescription:(NSString**)error
{
  if(obj)
*obj = string;
  return YES;
}

-(BOOL)isPartialStringValid:(NSString*)partialString
  newEditingString:(NSString**)newString
  errorDescription:(NSString**)error
{
  //return YES; //doesn't help either
  if([partialString isEqual:@""])
return YES;
  NSString* correct =
[[NSNumber numberWithInt:[partialString intValue]] stringValue];
  return [correct isEqual: partialString];
}

@end

Thanks for your help,
Yann

Joar wasn't disputing the use of -drain, he was asking about the use
of +new over +alloc/-init. AFAIK, there is no official documentation
that recommends the former over the latter.

Thanks for making sense of the sparse documentation ;-)

Text attachment not deleted from NSTextView

[Luong Dang]

Hi all,

I'm having a problem with NSTextView: I programmatically insert an  
image attachment into an NSTextView. However, when I delete the text  
from my GUI the image didn't go away, even though from the code, I can  
see that NSAttachmentCharacter is removed from my attributed string.


Here's the code I'm using:

NSFileWrapper * fw = [[NSFileWrapper alloc]  
initWithPath:@"somefile.gif"];
NSTextAttachment * attachment = [[NSTextAttachment alloc]  
initWithFileWrapper:fw];
NSAttributedString * string = [NSAttributedString  
attributedStringWithAttachment:attachment];


[[textView textStorage] appendAttributedString: string];

Some additional info if they help:
* The image is an animated gif file
* I use automatic garbage collection - could it be that GC is not  
finalizing my objects in time?


Thanks,
Luong.

Rotating an NSTableView.

[Peter Hudson]

I have an NSTable View inside an NSSplitView.
I rotate the table view by sending   rotateByAngle:270  to the  
enclosing scroll view.

The table lands up exactly as I want it with vertical rows.

The problem is that when I resize the split view the NSTableView does  
not change size to fit the split view movement as it does when the  
table is not rotated.


Does anyone have any idea what is going on.  I've tried all the usual  
games with setting frame and bounds etc - but to no avail.

Create a pop-up button. Set it to "pull down" mode. The first menu

If you don't notice this then the items obviously don't show up at

[SOLVED] Re: FSCopyObjectASync Not Calling Callback In Cocoa

[Matt Long]

Thanks for the help. The first response I got (Steve) was the correct  
one for what I was needing. I didn't correctly schedule with the run  
loop.


Here's a couple of points

Mike Fischer suggested that the operation was completing in less time  
than the one second specified. This is a good thought, but the file  
I'm copying is about 1GB (video file).


John Daub suggested that it might be a C++ issue. It doesn't appear  
that this is the issue. I've gotten it working without specifying the  
extern C pre-processor calls. Thanks, though.


Stephen Butler pointed out that I need to use -[NSString  
fileSystemRepresentation]. I have switched to this and it works. I not  
real familiar with this call, but it looks like it's working. I'll  
look into why this is the better choice. I'm just not familiar.


Anyhow, thanks again. If you would like to see the completed code,  
write me offline. I am updating a progress indicator in the callback.  
Seems to work pretty well.

trouble debugging input method remotely

[Daniel Child]

I am trying to set up remote debugging for input methods using Xcode.  
For starters, I'm trying to use Apple's sample, but am having a number  
of issues.


One is that I am not sure where/how to set up the shared build  
location in the case of an input method. To run an input method, you  
need to drop it into Library"Input Methods", but remote debugging  
usually suggests setting up a shared location like /Users/Shared/ 
Projects or the like. Can input methods be run from such a location  
during debugging?


Secondly, I'm confused about the use of symbolic links for the latter  
(shared location). I have authorized access using ssh-keygen. That  
works fine. The problem is that when I try to debug gdb says the  
executable is not found based on the symbolic link I set up.


Here's where I'm unclear. If the LOCAL computer (the one that will be  
used to develop and run the debugging) has its build location set to:


/Users/Shared/MyInputMethod

then on REMOTE (the computer used to execute the input method during  
debugging), should the link be inside a folder (on REMOTE) called / 
Users/Shared/MyInputMethod or should the link itself be found at / 
Users/Shared/MyInputMethod? (My guess is at, but at this point neither  
approach is working.)


And is it correct to have the link placed on REMOTE (the executable  
host) point to:


/Volumes//Users/Shared/MyInputMethod ???

Thanks for looking.

(PS: I've already done the step of setting up remote debugging in  
Xcode and that seems to work. Problem is the link files not in the  
correct location.) When I set links as described above, the console  
errors are as follows (project called NumberInput0):

Programmatic "Size To Fit"

[Randall Meadows]

I am creating a bunch of controls (at least NSTextfield,  
NSPopupButton, NSSlider, and perhaps others) programmatically (that  
will eventually be shown in an NSTableView), and would like to apply  
the "Size To Fit" feature that IB provides.  However, there doesn't  
seem to be any API that does that.


Does IB simply brute-force the resizing for every type of view, or am  
I missing the appropriate call in the NSView API?


Thanks!

For almost all intents and purposes, it returns UTF-8, because that's what
the APIs to HFS+, et al expect. However, it's conceivable that some file
system might want path strings in another (legacy) format. Say, Shift_JIS,
Big5, or KOI8-R.

I'm not sure any do. I'm not even sure the vfs layer allows the fs to
register a preference. But there's a function for it, so you might as well
use it.

It returns UTF-8, but with a very specific Unicode composition:

When you think about this, it is really not possible, as
fileSystemRepresentation works on any string, including those that do
not represent existing files. There is no way to know, in general,
which filesystem a particular path will live on.

Re: trouble debugging input method remotely

[Daniel Child]

People from Apple who develop input methods told me as much.  
Presumably, since you are typing from the keyboard to test the input  
method itself, having it run on the same computer causes problems: you  
are trying to allow the interaction with the executable to be natural,  
but how do you know keyboard input is intended for Xcode or the client  
application (like TextEdit, which "hosts" the test).

Others have mentioned -[NSControl sizeToFit], but I thought it was  
worth reminding that when you can't find a method to do what you want  
in a given class, remember to check its superclasses for methods the  
class inherits for what you seek.

It's not that this varies from one file system to another on the same

from the details of that representation.

Re: Programmatic "Size To Fit"

[John Stiles]

An NSView doesn't have an associated cell, so "size to fit" doesn't 
really have a meaningful answer. Size-to-fit works by asking the cell 
what size it should be.


For a box, you could just enumerate the subviews and get the union of 
all the subview frames.

Re: trouble debugging input method remotely

[Daniel Child]

I should have been clearer explaining why you need remote debugging.  
The focus while test-typing the input method will be something like  
TextEdit. You cannot be "inside" TextEdit and Xcode at the same time.  
You are either typing in one app or the other.


So the idea is to run the executable on a remote computer, using some  
client (Word / TextEdit, whatever), while running Xcode on the local  
computer to debug. At least, that's how I understand it.


FWIW, I tried simply copying the build folder over to the mirror UNIX  
path on remote (/Users/Shared/ and still got an error.


(following successful authentication)

This GDB was configured as "powerpc-apple-darwin".Architecture of file  
not recognized.

You can't do that without a process to debug.

I'm wondering about the architecture not being recognized. Is this an  
Intel vs PPC thing or something else? My LOCAL computer is an Intel,  
the REMOTE is a PPC Since this was Apple's sample, I'm leaving the  
SDK/target as is since presumably those are the settings they  
used???

 Does IB simply brute-force the resizing for every type of view, or 
 am I missing the appropriate call in the NSView API?

Just to throw this out there to...

IB's size-to-fit function is still very much a mystery.  For all my IB palettes 
(IB 2.x) and plug-ins (IB 3.x), I added a custom mySizeToFit method for most of 
my controls.  Then, the inspector had a button that would invoke that method.  
As much as possible, it would rely on framework routines such as cellSize to 
return an appropriate size for each cell.

Multi-cell controls would of course need to do a proper union and optionally 
space things out too.  At the end of the method, I would then do a setFrame (or 
was that setSize?)

Anyhow, I found it really weird that IB's size to fit menu never would invoke 
sizeToFit in code.  breakpoints and logging lines never were hit.  There's 
still a bit of IB magic going on where I think IB will only do work for 
specific classes.

The other nice thing of your own sizeToFit methods is that you could then add 
it to your view classes too.  I would recommend perhaps a protocol you could 
mix in to all your views/controls that needed such an API.  And, if you're 
doing IB palettes/plug-ins, you'd have something you could tap into as well.

Re: Programmatic "Size To Fit"

[Stuart Malin]

SizeToFit will expand horizontally. If you need to constrain  
horizontal width...  here's some code I use resize NSTextField  
instances vertically while constraining the horizontal width to fit  
within some contained view.  I believe this approach would work with  
other sorts of controls. Adapt to your needs...


	float targetWidth = <>;		// subtract  
4 for 2 pixel gutter on either side


// resize the textField to make all the text visible
	NSRect r = NSMakeRect(0, 0, targetWidth, MAXFLOAT);		// confining  
bounds: limited width, huge height
	NSSize s = [[textfield cell] cellSizeForBounds:r];		// returns  
minimum size needed to hold the receiver

s.width = targetWidth;  // 
force to consistent width
	[textfield setFrameSize:s];	// and now set the textField's frame  
size


In my application, the textfield sits within some other view  
(theContentView), and I get its width thus:


	float targetWidth = [theContentView frame].size.width - 4.0;	//  
subtract 4 for 2 pixel gutter on either side


If you have an existing control and want its width to remain fixed,  
you could always get its current width and use this as the targetWidth.

Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes

I am creating a bunch of controls (at least NSTextfield,
NSPopupButton, NSSlider, and perhaps others) programmatically (that
will eventually be shown in an NSTableView), and would like to apply
the "Size To Fit" feature that IB provides.  However, there doesn't
seem to be any API that does that.

Does IB simply brute-force the resizing for every type of view, or am
I missing the appropriate call in the NSView API?

Thanks!

So from Mike Ash's comments it seems like something else must be  
going on. What set me down this path is the comment in the docs for  
[NSApplcation beginSheet: modalForWindow: ...] (which I assume  
[NSAlert beginSheetModalForWindow: calls ?)


Use this method in cases where you do not need to do any additional  
background processing while your sheet runs. This method consumes  
only enough CPU time to process events and dispatch them to the  
action methods associated with the sheet. If you want to perform  
additional background processing, use runModalSession:together with  
an NSModalSession object instead.


The comment about additional background processing is confusing to  
me. Does handling messages on an NSConnection count as background  
processing ? Do I have to go to the expense of using  
runModalSession: (Mike Ash's comments seem to suggest not, it  
should 'just work')


Bottom line - it sounds like beginSheetModalForWindow shouldn't  
block connection handling but it seems to in my case - where should  
I look begin to look for the cause of this ?

Great to hear.  Bugs or departures from documentation are not rare,  
especially with APIs that started at or before Cheetah (10.0).  So  
sometimes things don't work as expected or documentation is misleading  
or confusing.  The docs for this method should probably be revisited  
by Apple.

The problem is that when I resize the split view the NSTableView

the table is not rotated.


Does anyone have any idea what is going on.  I've tried all the

Is your splitview splitting horizontal or vertical?

Have you tried rotating the enclosing scrollview instead of the table  
itself?


Have you tried manually calling -tile on the table?

Note: I haven't tried this myselfthese are just things that came  
to mind.

NSWindow With IB

[Philip Bridson]

Hi There,

Is there any way to create a Window with no title-bar in IB? I want  
one that is only displayed while the app launches like many apps do.  
I create all my windows with IB and I know that I can use  
NSBorderlessWindowMask if I create one programatically but is there  
anyway of doing it in IB as my current window loads with a title bar.  
I don't mind manipulating it with code if I have to.


Many thanks,

Phil.

NSArrayController issue

[Måns Severin]

Hi,

I've been working with an NSArrayController containing CoreData entity  
objects.
I've created a segmented control for cycling through these object  
(similar to Safari's Back/Forward buttons).
For some reason, after calling the NSArrayController methods  
selectNext: and selectPrevious: from my controller object, the  
canSelectNext and canSelectPrevious controller keys doesn't reflect  
the new selection.


In the code i provide I have a stepProjects: action called from the  
segmented control (oStepper), it calls the oProjectsController to  
select next/previous records. It then updates the UI which sets  
enabled flags for the segments in the segment control. Problem is,
canSelectPrevious and canSelectNext does not return correct value even  
if the array controller has selected the first or last element. If I  
instead of the [self updateUI] call create an NSTimer object, which in  
turn does an updateUI call after a 0.2 second delay, I get a correct  
update of the segment control.


Is there some kind of delegate / observer method of the  
NSArrayController to see when it is done changing selection?


I wouldn't have had this problem if I could bind the segments directly  
in Interface Builder, but I am not able to do that.

Anyone have had the same issue?

Best Regards
Måns Severin


Code Listing:

- (void)updateUI
{
[self updateStepper];
}

- (IBAction)stepProjects:(id)sender
{
switch ( [oStepper selectedSegment] )
{
case 0:
[oProjectsController selectPrevious:self];
break;

case 1:
[oProjectsController selectNext:self];
break;
}

[self updateUI];
}

- (void)updateStepper
{
	[oStepper setEnabled:[oProjectsController canSelectPrevious]  
forSegment:0];

[oStepper setEnabled:[oProjectsController canSelectNext] forSegment:1];

NSPopUpButton doesn't show list when used inside a menu item

[Angel Todorov]

Hi,
I have a regular menu (File menu) for my app. One of the menu items (New
...)  is a custom view , which happens to contain a NSPopUpButton (i.e.
simple drop down). I create that by linking / connecting (Ctrl + drag) the
"New..." item to my custom view. At runtime,  the drop down is correctly
populated, but when i click the arrow to show the list of values, it doesn't
expand. It works fine when used in the default window of my application.

Is it possible to have a PopUpButton inside a MenuItem itself? Thanks very
much for the feedback.

P.S: A combo box control also doesn't open / expand when used in a
menuitem.

While CCFL backlights can only dim so far, LED backlights can

Is there any way (perhaps even low-level communications with the

very low?

Re: NSPopUpButton doesn't show list when used inside a menu item

Recursive menu tracking? I can't say I'm surprised that this doesn't work :)
Honestly I have to say that this sounds like a really weird UI. I would

You should also take into account when using the sizeToFit message

Displaying one NSTextStorage with two sets of temporary attributes

[Adam C.M. Solove]

Hello all,

In the episode of Late Night Cocoa on the text system, [
http://www.macdevnet.com/index.php/shows/latenightcocoa/37-latenightcocoa/93-lnc005
] Juan Pablo Claude described a setup with multiple NSLayoutManagers
editing text from the same NSTextStorage and then said, off-hand, that
you might do this if you wanted to display the same text with
different fonts. I am curious if anyone could discuss how this might
be done: displaying the same underlying attributed string, but
formatting it before the NSLayoutManager tries to lay it out and
formatting it back when the NSTextView sends back changes. I cannot
find specific information on subclassing NSLayoutManager to make these
sorts of changes.

(I know there is an Apple demo [TextViewConfig,
http://developer.apple.com/samplecode/TextViewConfig/index.html] which
shows multiple layout managers, but these both render the exact same
attributed string (except that one view has been essentially zoomed to
twice the size). I am curious if it is possible to actually change
temporary attributes in one LayoutManager but not the other, and then
change them back appropriately before sending events to the
NSTextStorage.)

End technical discussion

Begin back story for those interested:

I am a relatively new Cocoa developer working on an open-source
project for academics. I  recently spent considerable time working on
a web-based version of this application before learning that the
hardest part was technically infeasible because of some limitations in
HTML's designmode. In starting with Cocoa, I will be happy if the
project and required learning takes many years, so long as there is an
answer in advance to this one difficult question.

The application is an editor for a specific subset of the TEI XML
guidelines for encoding literary works and scholarly commentaries on
them. The underlying data maps very nicely into an attributed string,
because it is a single text divided up into separate 'series' (main
text, footnotes, cross-links) The series are all anchored together,
but would best be displayed apart, with first the main text, then each
series of notes. I believe the easiest way to do this would be to have
a single underlying NSTextStorage, to attribute every range of text to
one series, and then to create various subclasses (or formatters) for
NSLayoutManager that each display only text in one particular series.
I suspect this could also be done with a custom Typesetter and the
method setNotShownAttribute:forGlyphAtIndex:, but am curious if there
is a more general hook to set attributes on the string before layout.

Thank you,

Adam Solove

Interesting NSPathControl Behavior

[Mike Rossetti]

So I've discovered an interesting behavior in NSPathControl and am  
wondering if it warrants a Radar.


I'm building up my own presentation of the file path to be shown in  
the NSPathControl.  Specifically, if the file for which the path is  
being presented is in some standard location then I'm abbreviating the  
path.  As a simple example, if the file is in ~/Documents/FIle.txt  
then instead of:


Users > User A > Documents > File.txt

I will show:

Documents > File.txt

The approach I'm taking is to pass a payload (an NSArray) to my  
customization of NSPathControl's setObjectValue.  In setObjectValue I  
compose a string ("/Documents/File.txt") that I pass on to [super  
setObjectValue:], which sets up the NSPathComponentCells just fine.   
Then I iterate over the pathComponentCells calling each one's setURL.   
(And in this example that would be 'file://localhost/Users/User A/ 
Documents/' for the first cell, and 'file://localhost/Users/User A/ 
Documents/File.txt' for the second cell.)


Doing this in a forward direction gives the following cell URLs:

0. file://localhost/Users/User A/Documents/File.txt
1. NSPathCell://localhost/Documents/File.txt

Say what?

Interestingly, if I do this in a reverse direction I get the _proper_  
cell URLs:


0. file://localhost/Users/User A/Documents/
1. file://localhost/Users/User A/Documents/File.txt

If this is a bug, I'll be happy to write up a small test app to  
present the problem.


Mike

class_addMethod and type encodings.

[Ross Tulloch]

Hi,

I've been experimenting with adding methods to classes at runtime and  
have some questions regarding the use and importance of type encodings.


1) class_addMethod requires a types array. This array describes the  
types of the arguments to the method. The type encodings page simply  
states that this info "assists the runtime". I'm wondering how (and  
when) this type information is used by the runtime? In my testing I've  
found the added methods work fine even if you pass an empty types  
string. How bad an idea is passing an empty types string?


2) I've seen some code which uses type encodings like "@[EMAIL PROTECTED]@4". I  
can't find any doco for this style of encoding. Any hints?


3) The only doco I can find for type encodings in ObjC is the "Runtime  
System > Type Encodings" page. Is there any other doco I should be  
reading?



Thanks,
Ross.

Not sure if this applies, but - for those experiencing all these  
problems - did you turn off that 'zerolink' thing? I've heard that  
throws it for a loop, too. (This may not apply anymore, but I  
remember that used to be a 'feature' back in XCode 1 or so.)

doesn't work as well as it should, but I'm fairly tolerant given  
how bad it was.


I've never used gdb from the command-line. Is it any more reliable  
when used directly? Would it be worth trying?


Even when the Xcode interface to the debugger couldn't display a  
variable, gdb always had the right data. If you are having  
consistent problems with variable display timeouts, make friends  
with the gdb prompt. It's better than NSLog and/or printf. Is it a  
pain? Yeah. Is it better than having nothing? Yep.


The whole GUI debugging experience seems to work much better with  
DWARF than with stabs, so if anyone hasn't moved to DWARF yet, I'd  
recommend it.

Re: How Do You Open Default Web Browser and goto URL?

[Peter Zegelin]

Thanks  - I have got it to work in both cases except where I add a  
subject to the mailto:



This works:   NSString *applicationURL = @"mailto:[EMAIL PROTECTED] 
 ";


but this doesn't:   NSString *applicationURL = @"mailto:[EMAIL PROTECTED] 
 - Require Registration Help ";


into:  [[NSWorkspace sharedWorkspace] openURL:[NSURL  
URLWithString:applicationURL]];



If I shorten the Subject to just subject=AlphaDraw it works but it  
looks like any spaces are causing the method to fail.

Any suggestions what may be wrong?

thanks again,

Peter

You need to URL-encode the subject.

NSString *applicationURL = @"mailto:[EMAIL PROTECTED] 
"

Spaces aren't legal in URLs, so the NSURL object you're getting is  
nil. You have to URL-encode the subject string, calling - 
stringByAddingPercentEscapesUsingEncoding:.

Those URLs usually need escapes to work.  Try running the URL through  
CFURLCreateStringByAddingPercentEscapes before sending the NSWorkspace.

1) class_addMethod requires a types array. This array describes the

I've found the added methods work fine even if you pass an empty

The types are used by NSMethodSignature, which in turn gets used by  
NSInvocation and DistributedObjects, and probably other things.


3) The only doco I can find for type encodings in ObjC is the

The docs I know of are down in the GCC documentation, in the "compiler  
extensions for Objective-C" section. It's buried somewhere in the  
reference library in /Developer.

Re: Cache Class review (low priority)

How is my code and comments?


Much better! But here are a few remaining issues:

In general, your autorelease pools (in all these methods) aren't  
necessary. Typically you only need to add pools as optimizations, if  
you have a loop that iterates many times and creates objects every time.


[NSTimer scheduledTimerWithTimeInterval: defaultSleepTime target:  
self selector: @selector(run:) userInfo: nil repeats: YES];


That timer is autoreleased, so you have to retain it or it'll go away  
after your init method returns. Typically you'd then assign it to an  
ivar; then when you need to stop the timer, you call -invalidate and - 
release on it.



// we need to verify that the object isn't already in the 
dictionary
// if it is we just need to touch it

id dictionaryObject = [theDictionary objectForKey: theID];

if (dictionaryObject == nil){
[theDictionary setObject: itemArray forKey: theID];
} else {
[self touch: theID];
}


I don't think you want to do this. It has the side effect that you  
can't change the value for a key — it'll just ignore the new value and  
bump the timestamp on the old one. If you simply always do the  
setObject:forKey: call, it'll do the right thing.



NSDate *now = [NSDate date];

		NSDate *date = [[theDictionary objectForKey: theID] objectAtIndex:  
1];

date = now;


That last line doesn't update the stored data. It just changes the  
value of the local variable 'date'. What you want is

NSDate *now = [NSDate date];
	[[theDictionary objectForKey: theID] replaceObjectAtIndex: 1  
withObject: now];



if ([date compare: now] == NSOrderedDescending) {
[self removeItem: key];


Isn't that going to remove everything from the dictionary whenever it  
runs? 'date' is the time the object was added or touched, which is in  
the past so by definition it's always going to be less than 'now'. You  
could change that test to

if ([date timeIntervalSinceNow] < -expirationPeriod ) ...
where 'expirationPeriod' is an NSTimeInterval, a number of seconds  
that values can live in the cache.



/** This method sees if a key is in the array */
- (bool) containsKey: (NSString *) theID {

NSArray *array = [theDictionary objectForKey: theID];

if (array == nil){
return false;
} else {
return true;
}

}


Collections don't usually have a separate 'contains' method (at least  
not in Cocoa / CoreFoundation), because it's just as easy to call - 
get: But that's a matter of taste. Also, you could simplify the if/ 
else statement down to

return (array != nil);

Finally, I'd recommend writing some unit tests for this class that  
exercise all of its functionality. They would have told you that  
values can't be changed and expiration never happens, and would also  
verify your future fixes.

Um, that's ... weird. I suggest you use a regular submenu instead.  
Many apps have one of those for the New command, when they can create  
several types of new documents.


Putting a custom control in a menu, that does the same job as an  
existing mechanism, but differently, it just going to make your app  
look inconsistent and confusing.

Dragging a window

[Geert B. Clemmensen]

Hello,

Looking at an old NEXTSTEP application where you e.g. in a mouseDown  
method could have the window dragged by using the dragFrom: method (as  
if you were clicking on the window title bar). The dragFrom: method  
isn't available in Cocoa. Any recommendation as to how one can drag a  
window (without a normal title bar)?

Or, if the window has been created using

 styleMask:NSBorderlessWindowMask

you arrange that whatever view(s) intercept mouseDown
and mouseDragged will do the job of moving the window
appropriately.

CGevent and cocoa compatibility

Does anyone know how to get the keycode out of a NX_SYSDEFINED  
CGEvent?  If so, is that keycode the same thing you'd get out of say  
(([event data1] & 0x) >> 16)? I'm trying to support the media  
keys on the Apple aluminum keyboards without having iTunes also get  
the events.


Thanks,
