Working with svg
Hi, I'm using web-kit for loading an svg map in my application, I want to store the map data in memory for redisplay with some mods (like changing the colors at given population data etc.). I'm thinking to trasform svg data in xml plain data and managing an nsxmldocument for storing changes but I don't know how render the web- view with xml Perhaps I shouldn't convert data to xml but working directly with svg format, how can I store the whole file in memory for editing? I'm a rookie programmer I'm not sure my question has sense :) Bye ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: List Running apps and windows
PD: I have tried the UIElementInspector code and it also says that the
App is not trusted, but it succeeds in geting other apps info. Instead
when I run
AXUIElementRef ref=AXUIElementCreateApplication(pid);
AXUIElementCopyAttributeNames(ref, (CFArrayRef *)theNames);
theNames is empty.
Why is this happening?

Re: Newbie Question: Controls not redrawing on changes
Yes, it appears that I want an NSPanel instead of an NSWindow for my modal dialogs, but I think the modality is a red herring here: I just tried adding the same checkbox and button controls to a floating window and a document window: they don't visibly update based on mouse clicks there, either (although they still send actions to their targets) There's an [NSWindow setAutodisplay:YES] method which again looks like it's just what I need, except that it's already turned on (I just did it explicitly to be sure, no change). I've tried setting the window's backing store to BackingStoreNonretained, which also doesn't have any obvious effect. I'm correct in my assumption that this is supposed to work, yes? If I create a window, nest a checkbox in it's main view, and start the main event loop, clicks in the checkbox should keep toggling the value of the checkbox and updating the screen, right?

Re: Newbie Question: Controls not redrawing on changes
Are you sure you're running the event loop correctly? It sounds to me that Cocoa is not getting a chance to do its usual behaviour of calling -displayIfNeeded at the end of the event loop. What if you manually call that method yourself? Mike.

CALayer retain count problem when changing geometry
Hi,
I'm having a problem with the retain count of CALayers. It seems that
when changing geometry related properties, such as bounds or position,
the retain count is decremented. Below is a simple example that
exhibits the problem. In the example, if changeName is called, the
retain count of the layer isn't touched, but if changePosition is
called, the retain count is decremented so far that the overridden
dealloc method is called.
I can hide the problem by turning on garbage collection, but that's
cheating. Does anyone have any ideas as to what might be causing this?
Cheers,
Pete

iPhone SDK Question
Well I'm not willing to switch to ATT for my cell, but I would like to develop for iPod and iPhone. I've been messing with the SDK and it seems fairly straight forward, however I am in love with my PPC and unwilling to give it up until Apple stops making OSes for it. Therefore I am using the SDK on my G5. It took a little tweeking, and googling to get the thing to compile but it all runs now. So my question is: If a compiled iPhone/iPod app runs on the simulator on my PPC will it actually run on the iPhone/iPod? I checked the apps and they say they are PPC even though the arch variable says its the right one. So I'm a bit confuzzled about this as it seems it should at the very least say universal according to the apps in the sdk. P.S. Before asking this I looked for a iPhone dev list but there doesn't seem to be one or I didn't see it. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Under graphically I mean for example zooming of some parts of the window or change colors and so on and also to preserve the funcionality of the original window. So, basically you're trying to write a GUI editor, like Interface Builder? In that case, I think what you'd really want to do is build your view hierarchy slightly differently. It's been a while since I tried writing a GUI editor in Cocoa, and I did half a dozen in Classic/ Carbon, so I may be mixing up things here, but there are several approaches, all of which might work depending on what you want to do: 1) Use NSImage and NSBitmapImageRep's -initWithFocusedViewRect: method to create a snapshot of each view. Then you can create a custom view for each view that draws such a snapshot, accepts clicks, draws a selected look, etc. 2) Wrap each view in a container view. I think there was some way to make a view get clicks before its subviews get them. That way, you can intercept the clicks and do something special with them when needed, and also draw a highlight to indicate a selection. Views are objects just like any other, so you can easily create a new one using alloc/initWithFrame:, then use addSubview to insert it in another view etc., and thus dynamically change the view hierarchy or even build a completely new one, without a NIB. Same applies to NSWindows.

awakeFromUndo?
I have a Cocoa app presenting a classic master-detail view of managed
objects, each of which represents a machine on a network and has a
string property address. I also have a class which monitors the
status of a networked machine whose initialiser takes such an address.
Therefore in awakeFromInsert and awakeFromFetch in my NSManagedObject
subclass I add self as an observer for self's address property, and in
the observeValueForKeyPath:... method I set up a new or replacement
monitoring object. Conversely, in willTurnIntoFault I remove the
monitoring object and the observer.
This works fine as I add and remove items using my array controller,
but if I remove an item and then undo that removal, the object is
reinserted into the context, but without awaking either from insert or
from fetch. I am wondering where I should put my hook for adding the
address observer, or whether I should be doing something different
altogether.
Thanks,
Hamish
P.S. I have written the following workaround, but it relies on a private method:
// NSManagedObjectContextWorkaround.h
#import Cocoa/Cocoa.h
@interface NSManagedObjectContextWorkaround : NSManagedObjectContext
{
}
@end
@interface NSManagedObjectContext (PrivateNSManagedObjectContextWorkaround)
- (void)_undoDeletions:(id)object;
@end
// NSManagedObjectContextWorkaround.m
#import NSManagedObjectContextWorkaround.h
@implementation NSManagedObjectContextWorkaround
- (void)_undoDeletions:(id)deletions
{
[super _undoDeletions:deletions];
@try
{
for (NSManagedObject *deletion in [deletions objectAtIndex:0])
[deletion awakeFromFetch]; // treating this as a fetch
works for my purposes
}
@catch (NSException *exception)
{
}

Using ObjC to access SOAP/WSDL server
Greetings Jeff fellow Cocoa Developers:
I need to access a SOAP/WSDL server.
I'm trying to convert some Java code to its ObjC equivalent.
Client (Mac) --- SOAP WSDL server.
Here's where I'm coming from:
1) I need to make a POST connection.
2) Content type is SOAP (text/xml).
3) I need to set a request property as shown below.
This is a synchronous connection, waiting for a response close the connection.
..
private String SOAP_SERVER_URL = http://myconnect.eccron.com/soap/sync;;
private final String SOAP_ACTION = http://myconn.eccron.com/2007/02;;
..
xmlstream = (StreamConnection)Connector.open(SOAP_SERVER_URL +
;deviceside=false,Connector.READ_WRITE,true);
connection = (HttpConnection)xmlstream;
connection.setRequestMethod(HttpConnection.POST);
connection.setRequestProperty(Content-Type, text/xml; charset=utf-8);
connection.setRequestProperty(SOAPAction,SOAP_ACTION);
..
4) Send the SOAP envelope:
...
// Send Request
---
OutputStream out = connection.openOutputStream();
out.write(xmlreq.getBytes()); // 'xmlreq' is a concatenated XML string that
is the SOAP envelope message.
out.flush();
out.close();
5) And I need to interpret the response:
// Get Response
---
// Get the connection status
status = connection.getResponseCode();
...
=
I don't need to know any particular socket. I'm told that all I need to do is
to access a given URI stated above.
I've tested the URI with a browser; and I do get a contact, albeit access was
denied since I didn't supply a SOAP message with authorization.
I've read some blogs and follow some of the CocoaDev discussions.
I've learned that I should use NSFileHandle.
I believe you're onto something; and I need your (and/or other CococDev
members) help.
What I've gotten so far is:
NSFileHandle *myFileHandle ;
// ... generate a file descriptor of the target URL...
// [myFileHandle initWithFileDescriptor:fileDescriptor closeOnDealloc:YES];
-(void)process:(id)notification {
NSFileHandle *fh = [notification object];
NSMutableData *data = [fh availableData];
NSString *dataString = [[NSString alloc] initWithData:data
encoding:NSUTF8StringEncoding];
/* Process the data however you need to here */
[dataString release];
}
...
I'm hitting a brick wall here.
I know there's a way...
Can you (and/or fellow CocoaDev members) please supply some guidance here
and/or point to some simple docs?
Thanks; I would truly appreciate it!
Regards,
Ric

I'm periodically getting this message
*** -[NSConcreteFileHandle availableData]: Invalid argument

Here's what I'm doing: I'm using NSFileHandle to handle socket communications
with a remote server. I create an old-fashioned network socket, allocate an
NSFileHandle, feed it the socket using initWithFileDescriptor:, and then use
readInBackgroundAndNotify after specifying to receive
NSFileHandleReadCompletionNotifications. The odd thing is that despite this
error getting printed in the console, my code is working as expected - I am
getting data from the file handle and the data appears to be 100% correct.
My call back method looks like this:
- (void)updateStatusCallback:(id) notification
{
NSFileHandle *fh = [notification object];
NSData *data = [fh availableData]; // - This call generates the
message in the console sometimes... but it works
NSString *theString = [[NSString alloc] initWithData:data
encoding:NSUTF8StringEncoding];
// code to process the response
}
In the debugger, I see no difference in fh between calls that generate the
message and those that don't - it's always an NSConcreteFileHandle with a
positive file descriptor. This message show up rougly about 10% of the time
that the callback gets called, although it's not consistent.
Thanks in advance!

I read in the NIB using:
[NSBundle loadNibNamed:@tableWindow owner:tableController]
Did you set the file's owner of the nib to your TableController class? Are
all the outlets connected? Is tableController non-nil when you call the
above method?
Indeed the NIB tableWindow has file's Owner set to tableController and
there is a connection made to dataTable
from a TableController object.
I get a pointer to tableController, but the field dataTable is nil.
What do you mean by get a pointer to tableController? How are you getting
the pointer? Should you have already created it before calling -loadNibNamed
? If your outlet is nil, it is not getting connected.
How do I get dataTable to point to the NSTableView in the nib?
1. Set the File's Owner in the nib to your custom class
2. Connect the dataTable outlet to the NSTableView

Re: Using ObjC to access SOAP/WSDL server
Thanks for the reply. I've been doing research and found the NSURL... classes appear to do what I was looking for: Accessing data from a server using a SOAP envelope. 1) The server provides me with a URL (no port# given; just the http URL). 2) I can set/adjust the authority parameters via NSURL... routines. 3) I need to grab what's returned. I think NSURL can do this. Note: all communications to/from are in XML format. The server DOES have a WSDL file, but it's not available to the public. I tried to create stubs using WSMakeStubs with the given http URL. But I got an error back. I'm told that the .wsdl is hidden. That was my 'phase 1' plan. Now I'm checking the NSURL... route. I'll study further this evening. Thanks again... .. and I shall study all replies! Regards, Ric. On 05/04/2008 12:23 Nir Soffer wrote ..

Cannot remove an observer ... because it is not registered as an observer.
Hello, I now have two projects where I am getting the error below. I've tried some obvious things like adding calls to will|did Access|Change ValueForKey to my custom methods and also ensuring key-value compliance by adding dummy setters. Here is the error. Cannot remove an observer NSTableBinder 0x158a70 for the key path name from Alternative 0x15abd0 because it is not registered as an observer. It doesn't help that 'it' is ambiguous. Is there a workaround? A solution? I've asked about this previously and have included my previous post, below. Thanks, Steve Older post on the same subject: Cannot remove an observer Hello, I have what, in WebObjects, we used to call a master-slave display. I show a list of specific Products based on the selected Product Model, hereafter referred to as the 'Model'. So when a user picks a certain Model of sunglasses in the master list, she sees all the different size/color/lens combinations (Products) in the slave list. It works nicely. I use a contentSet binding (programmatically-generated if that makes a difference) to filter the slave list ie. bind it to the to-many relationship from Model to Products. ** In the slave (Product) list, I have a popup that allows the user to change a Product's Model. The popup is usually only used to fix data entry errors - e.g. specifying the wrong Model for a Product. Here is my problem. I noticed that changing the Model results in two exception: NSRangeException -- Cannot remove an observer NSKeyValueObservance 0x30bacf0 for the key path currentCost from Model 0x2a159a0 because it is not registered as an observer. and NSInternalInconsistencyException -- Cannot remove an observer ProductCategorySelectingArrayController 0x10e8650 for the key path model.currentCost from Product 0x1a68130, most likely because the value for the key model has changed without an appropriate KVO notification being sent. Check the KVO-compliance of the Product class. Googling, I found some other developers who have experienced this but no answers were offered. Note that the exceptions are complaining about one of the Model's attributes: currentCost. At other times, the exception complains about another attribute: 'active' -- its unclear whether that refers to the Model's 'active' attribute or the Product's 'active' attribute. Should I be reporting a bug? Thanks, Steve ** this likely has little to do with my question, but for the curious: I programmatically bind a contentSet based on the setting of a radio button with two choices: 'All' and Model. All means show all products, Model means show just the Products for the selected Model. I only have the problem in Model mode. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

The usual cause of this is that you have a property that isn't KVO- compliant. Something accesses your 'foo' property and registers as an observer of that property, and also as an observer of the object that's the property's current value; you change the value of 'foo' without letting anyone know; the observer then later decides to stop observing, gets your 'foo' property, and removes itself as an observer of that object.
