If you can guarantee that only one thread is accessing the object at a  
time, then that _is_ synchronization.




Also, is it ok to pass the object of this class as an argument to
performSelector:onThread:...?


Yes, that's safe so long as the calling thread doesn't access the  
object after it has been passed as an argument (unless such access is  
synchronized with the receiving thread).

Re: What does @loader_path refer to when loading ibplugins from a linked-in framework?

2008-09-25 Thread Dalzhim Dalzhim

Hello Michael,

I would have also thought that @loader_path would be the same thing no
matter how I load my ibplugin into interface builder and maybe it is in fact
the case, although this is the only thing that I haven't successfully
investigated that I can think of up to now in order to solve my problem.  As
I explained previously, the ibplugin I have built successfully loads up in
Interface Builder when I manually add it through the Plugin tab of the
Preferences window.  Although if I do not load it up manually and that I try
to have Interface Builder load it dynamically by opening a nib file in a
xcode project which links against a framework which includes my ibplugin in
its resources directory, the plugin never loads up and I cannot seem to find
any errors to help me find the source of the problem.

I have looked at the man page for dyld and I have found some documentation
in the Dynamic Library Programming Topics.  Although I tried using the
DYLD_PRINT_BINDINGS environment variable I didn't find where this logging is
being done.  Nothing appeared on the console after I ran interface builder
and repeated the usual process:

DYLD_PRINT_BINDINGS=1
cd /Developer/Applications/Interface\ Builder.app/Contents/MacOS
./Interface\ Builder


regards


-Dalzhim


2008/9/25 Michael Ash [EMAIL PROTECTED]

 I would have thought that @loader_path would be the same thing each
 time, namely the path of the plugin binary (minus the last path
 component, of course).

 I'm not sure exactly what your problem might be, but if you type 'man
 dyld' you'll find a bunch of debugging environment variables you can
 set which might help you track it down.

How to set up a thread listening to performSelector: messages?

2008-09-25 Thread Oleg Krupnov

I want to create a secondary thread with its run loop running
(sleeping) until a performSelector is sent to it. Then it wakes up,
performs the selector, and go to sleep again. I imagine it to be
something like this:

- (void)threadMain:(id)data
{
while(true)
{
[[NSRunLoop currentRunLoop] run];
}
}

However, the -[NSRunLoop run] method exits immediately, because, in
accord with the the docs, there are no input sources or timers
attached to the run loop.

So I need to set up an input source, right?. The docs say input
sources can be port-based or custom *OR* just performSelector calls. I
am interested only in the performSelector calls.

So what should my code look like to set up such input source?

I have also read the Defining a Custom Input Source doc section, but
it seems too complicated and not really relevant to what I want to do.
I don't actually need the input source, I just want to send messages
from one thread to another. How do I do it?

You can just create an NSPort and add it to the run loop.  It doesn't  
matter that you won't actually be using the port.

Re: How to set up a thread listening to performSelector: messages?

2008-09-25 Thread Oleg Krupnov

I actually have tried this. My code looks like this (is it correct?):

@implementation Worker

- (void)threadMain:(id)data
{
  runLoop = [NSRunLoop currentRunLoop];
  [runLoop addPort:[NSMachPort port] forMode:NSDefaultRunLoopMode];
  while(true)
  {
[runLoop run];
  }
}

- (void)processRequest:(id)sender
{
  NSLog(@hello);
}

@end

Then from the main thread I send:

[[worker runLoop] performSelector:@selector(processRequest:)
target:worker argument:request order:0 modes:[NSArray
arrayWithObject:NSDefaultRunLoopMode]];

This time the -[NSRunLoop run] method does not exit immediately.
However the problem is that processRequest is never called and the
-[NSRunLoop run] never exits.

What can be wrong? Should it work like this at all?

Filtering an NSArrayController using a to-many relationship

2008-09-25 Thread Danny Greg


Hi list,

In my data model 2 of my enities are Snap and Tag and they have a  
many-to-many relationship between them.


My UI is controlled by an NSArrayController bound to the Snap entity,  
I have a search field that sets the filter predicate of this  
NSArrayController (through code not bindings for various reasons). The  
array controller needs to be filtered to show any snaps which have a  
tag that matches the search field's string value.


Tag has an attribute of title so I tried a straight forward  
predicate such as ANY tags.title like [search string]  (where tags  
is the relationship on the Snap entity). But this fails every time.


There seem to be a lot of unanswered messages in the archives  
regarding this, can someone tell me what I'm missing?


Thanks

You can't do this. NSRunLoop is not thread safe. Since it is always
being used by the thread which it manages, this means that you cannot
use it from other threads at all.

If you can require 10.5, you can use this method:

- (void)performSelector:(SEL)aSelector onThread:(NSThread *)thr
withObject:(id)arg waitUntilDone:(BOOL)wait;

Otherwise, CFRunLoop is thread safe and does support this sort of
cross-thread invocation. You can also use Distributed Objects, use
that NSPort for messaging, or set up your own message queue system
using any number of mechanisms.

You cannot do this.  NSRunLoop is not thread safe and the docs say  
explicitly not to call methods on a different thread.


You need to use NSObject's performSelector:onThread:... method.

No, that's not how you do it.  NSRunLoop is not thread-safe.  That is,  
you can't message a run loop other than the current thread's.


You should use -performSelector:onThread:withObject:waitUntilDone:.   
You send it to the object you want to message -- the one that  
implements the method matching the selector.  You need to supply the  
NSThread object for the thread, which you can keep from the time when  
the thread was created.  Or the thread in question can query + 
[NSThread currentThread] and stash that object somewhere shared.  The  
withObject: parameter is an argument object which would be passed as  
an argument to the method, if the method and selector take an argument.

Ken

NSRunLoop is not known to be thread safe. Calling another thread's  
runloop methods does not works (as you see). You should only use this  
method one the current thread runloop.


Instead you should keep a pointer to the target thread and use [worker  
performSelector:onThread:withObject:waitUntilDone:].

Note that It works only on 10.5.

Unless you need to target pre-Leopard.

If you need to do that, you should use -performSelectorOnMainThread.

If you want to message a run loop that isn't on the main thread, then  
you will most likely need to use distributed objects.

Okay, I'll ante up. :-)

PDFDocument has methods for saving PDF's – since Leopard, annotations

PDFPage has methods for adding, removing annotations.

The PDFAnnotation classes ave initializers so that annotations can be

PDFView is really just a view.  While it has a lot of convenience

Causing systemUIServer to update the User Menu for Fast User Switching.

2008-09-25 Thread Ken Andrews

I¹ve got an app that creates users via dscl.  The users get created and
themselves are set up fine.
The problem I have is that the list of users in the fast user switching menu
does not get updated.
Using the login screen works fine.  The user is there just not in the fast
user switch pull down.

I can make it update by restarting systemUIServer but that is not something
I want to do.
If I add users from the system prefs they are immediately added to the user
list so there must be some method to get the list to update.
I send all the same notifications that system prefs sends but they do not
seem to help.
One thing that I did notice was in
SystemUIServer/Content/Resources/Autoload.plist
array
dict
keyid/key
integer-10014/integer
keymethod/key
string_userCanLoad/string
keypath/key
string/System/Library/CoreServices/Menu Extras/User.menu/string
/dict

This makes me think that there is some simple way to tell the ui server to
update just the user list.

Anyone have an idea of what it is?

Thanks,
Ken

Re: Horizontal SplitView Resize Question

2008-09-25 Thread chaitanya pandit


I'm not sure but you can try limiting the min and max coordinate using:
- (CGFloat)splitView:(NSSplitView *)sender constrainMaxCoordinate: 
(CGFloat)proposedMax ofSubviewAt:(NSInteger)offset
- (CGFloat)splitView:(NSSplitView *)sender constrainMinCoordinate: 
(CGFloat)proposedMin ofSubviewAt:(NSInteger)offset

Folks;

I have a horizontal split bar inside of a resizable view -the parent  
view grows both horizontally and vertically.
The standard behavior for horizontal split views appears to be that  
the the bottom view is grown or shrunk.
(In my testing this is true regardless of the resize attributes of  
the enclosed bottom view)

I have ALL of the resize widgets set ON for this splitView.

What I would like is the divider to stay fixed at its current height  
from the bottom throughout a resize and the top view to grow or  
shrink.
Is there a setting I am overlooking or is the way to accomplish this  
by overriding -splitViewDidResizeSubviews?


Thanks,
Steve

Interface Building help with box labels

2008-09-25 Thread Dale Jensen

Sorry if there is an Interface Builder specific list, I couldn't find  
one on the lists page.


I have a window with five boxes which are used to separate UI elements  
on the window.  Three of these five have their labels displayed in  
bold font, two do not, and nothing I've tried doing with the Bold  
command in the Font menu, or any of the settings in the Fonts window  
does anything at all to change the two plain text labels to bold.  On  
the other hand, nothing I do to the bold ones make them plain.  Paste  
and Match Style doesn't work either.  I can't see anything (obvious)  
different between the boxes in the Inspector.  New boxes that I drag  
out of the Library have plain font.


Any ideas, short of starting over?  This seems like really basic  
functionality, so there must be an easy solution.


Thanks!

  I've never seen this behavior. You should definitely file a bug:

http://bugreport.apple.com/

  I don't think you need to 'start over', though ... just select each
individual box, then choose Layout - Unimbed Objects from the menu.
Then select the now-unboxed items, and choose Layout - Embed Objects
In - Box. You should be able to recover in less than a minute.

What happens to the user dictionary when coalescing notifications in NSNotificationQueue?

2008-09-25 Thread Karan, Cem (Civ, ARL/CISD)

I've got a class that acts like a super-lightweight server within my program.  
It listens for incoming packets of information, decodes them, and then tells 
the rest of my code that something changed.  So far, this sounds like a job for 
NSNotificationCenter, except that I'm getting the packets by UDP, and don't 
want to tell all the listeners about every single update that happens; it would 
be better to coalesce them into one notification and notify them when the run 
loop is idle.  OK, so this sounds perfect for NSNotificationQueue with 
(NSNoticationCoalescingOnName|NSNotificationCoalescingOnSender) as the options. 
 The problem is that I want to send all the data along in the user dictionary.  
How is that coalesced?  Note that I want ALL the data I'm putting in the 
dictionary, not just the last user dict.

Thanks,
Cem Karan

You could create a method on your server class that returns the all  
the data as one NSData object. So, create a mutable data object in  
your server object and
every time you get a UDP packet, add that to the data and then post a  
notification. When the notification gets received, the notified object  
messages your server
object and retrieves all the data that way. Just make sure that the  
retrieve call is properly synchronized or that everything is running  
on the same thread

and you should have no problems. That's the way I would do it, anyway.

showing window causes EXC_BAD_ACCESS

2008-09-25 Thread Daniel Child


Hi,

I'm stumped. I have a button in a master window tied to a method that  
simply shows another window. The method is as simple as they come.


- (IBAction) showMLTableListings: (id) sender
{
[mLTableListingsWindow makeKeyAndOrderFront: self];
}

where mLTableListingsWindow is simply the reference to the data  
listing window cached within the App Controller.


If I press the button in question once, the window dutifully comes up.  
If I close the window and press the button a second time, I get  
EXC_BAD_ACCESS. Debugging, I found that both self and  
mLTableListingsWindow still exist.


Incidentally, the tables and windows were set up automatically using  
the entity object in IB, as I'm simply testing a CoreData app. I  
didn't set any of the bindings manually. This seems to happen on a  
number of my automatically generated CoreData windows?


Why is this happening? How can I track down the problem?

Thanks.

Daniel

Re: Adding external library in cocoa app

2008-09-25 Thread Scott Ribe

 The linker does link in static libraries, but it prefers dynamic
 libraries over static ones, and will always link to a dynamic library
 if one exists with the same name as the desired static one. Since
 there's no way to change this behavior, the only workaround is to add
 an absolute path to the static library as a linker flag in the other
 linker flags build settings.

Or put a copy of the static lib into a folder within your project, and drag
that one into the project. (And possibly delete the prior path from lib
paths, if you already dragged in the lib from the default location.)

Because some autoconf projects (such as liboil) depend on getting a  
list of symbols from a dynamic library in order to work, and thus  
break the moment you turn off shared libraries.

when they've received a message (so I can merge the cache back into  
the database), but that gets messier than I'd like.


Basically, if I know what is supported in coalescing, then I can work  
with it, if necessary, working around it.  I just need to know that  
things won't suddenly change one day.  That is why I'm trying to  
figure out the precise meaning of coalesce when it comes to the user  
dictionaries.

Use other key than tab to cycle through text fields

I would like to use a key other than tab to advance to the next text  
field, so that users can use a numeric keypad to enter something like  
11-22-33 and have 11, 22 and 33 end up in different text fields.


Is there an elegant way to do that, preferably cocoa binding compatible?

Re: Bindings Question

Normally you would have the table controlled by a NSArrayController. You would 
bind the button to an action method which would take the value from the text 
field and pass it to addObject: method of the array controller.

Nothing - it's a bug in IB.

Select all the items in the menu and then uncheck Hidden.

IB incorrectly keeps setting the Hidden state of menu items at  
various times.

Collections can be simple Attributes in Core Data

2008-09-25 Thread Jerry Krinock

When I first looked at Core Data, I saw that there was no such  
attribute type as Array or Set, and concluded that collections  
must be modelled as relationships.  This would be overkill in many  
cases, for example, in a Person type of application if you wanted to  
list the names of each Person's pets, but had no interest in the pets  
themselves.


So, one way I worked around this was to store the pet names as an  
attribute petNamesString of type String, using a delimiter character,  
and transforming on the way in and out of the store.  But now I find  
there is an even more natural way, which is to just leave them as a  
set or array, and store in an attribute of type Transformable.  The  
default transformer en/decodes the collection into/from an NSData, and  
everything just works.


I'm surprised that I've never seen this discussed or documented.  Is  
this going to get me into any trouble?

Re: Bindings Question

2008-09-25 Thread Eric Lee


Sorry for the late response...computer froze

Anyways, yeah, I have a NSArrayController, and I binded the table view  
to it, which let me actually add something. How do you bind a button  
to an action? Just control-drag?

Normally you would have the table controlled by a NSArrayController.  
You would bind the button to an action method which would take the  
value from the text field and pass it to addObject: method of the  
array controller.

I have an app that I'm making for practice that has a
tableview, and a
text field (and many other things, but the ones that are
the problem
are these two)

I just successfully changed my app to use bindings.
However, whenever
I pressed a button before, something would be added into a

NSMutableArray, and then the string would show up in the
table view.

Now, something IS added into the NSmutableArray, and will
show up, but
not the string. The thing that's added is just this
blank.

How do you solves these so that when I press the button,
the string in
the text field will actually be added and shown in the
table view?

Thanks!

Re: Use other key than tab to cycle through text fields

I'd suggest not using a different key from 'Tab', since that's very  
much hardwired into every Mac user.


Alternative, why not just detect when the field has the required  
number of characters and move to the next field automatically? For  
numeric entry this is much more user-friendly.

I believe this is the officially preferred solution:

http://developer.apple.com/samplecode/LoginItemsAE/index.html


Actually, Leopard introduced the LSSharedFileList API, which is the  
new preferred solution.  Unfortunately, this API is undocumented.  The  
only documentation (other than a brief mention in the release notes)  
is the header file:


/System/Library/Frameworks/CoreServices.framework/Frameworks/ 
LaunchServices.framework/Headers/LSSharedFileList.h

For implementing such a thing, see -[NSWindow selectNextKeyView:].

 Debugging, I found that both self and mLTableListingsWindow still exist.

 Sounds like your window is set to release when closed.  Uncheck this
 box in Interface Builder.

Wandering slightly, but this makes me wonder, why does this flag
exist? I can't think of a single reasonable use case for it, and it
seems to cause no end to trouble to people who have somehow enabled it
without knowing it. It violates the memory management rules and makes
programs crash. Is there a good use case for it, or is it just some
sort of leftover?
