NSView : Background bitmap drawing issue
I've written a subclass of NSView, which draws a NSImage, as the
background. All is working, but the only problem is in different
behavior on different Macs / OS versions. Here is the drawing code:
@interface BGSkinView : NSView {
NSImage *bg;
BOOL isLeo, isSnowLeo;
}
..
- (void)drawRect:(NSRect)rect {
NSGraphicsContext *ctx;
CGFloat y;
ctx = [NSGraphicsContext currentContext];
[ctx saveGraphicsState];
y = [self bounds].size.height;
///
if (!isLeo)
y++;
///
[ctx setPatternPhase:NSMakePoint(0, y)];
//
[[NSColor colorWithPatternImage:bg] set];
NSRectFill([self bounds]);
//
[ctx restoreGraphicsState];
}
isLeo is true on 10.5 and isSnowLeo is true on 10.6
I tested this code on my Mac with both 10.4, 10.5 and 10.6 and have
got a shift of the image for one pixel down on 10.4 and 10.6.
Therefore I've added the condition, selected above. But now I've got a
report from another 10.6 Mac, where my code shifts the background for
one pixel up. Thus, my patch with y++ should be disabled there.
As far as I understand, this effect is caused not by OS version, but
by some graphic subsystem feature. Could anybody tell me, what is this
one-pixel shift? Maybe it's some border, drawn outside of my view,
which I don't see?
Any help would be appreciated.
Thanks.

Re: make connections without InterfaceBuilder
Hello !
I don't know if this got answered but here is my attempt. It is just a
basic way of programmatically setting
an object as a application delegate and programmatically creating a
button on the applications main
window and setting it to perform an action when clicked.
I know that there are some issues about the way this is implemented
but it points the way to go.
Since I am a newbie my self any suggestions are more than welcome.
Brief explanation follows.
In Interface Builder:
- in MainMenu.xib create generic NSObject by adding it from the Library
- select that NSObject and in the Identity Inspector make it an
instance of our ApplicationController class
In Xcode:
- in awakeFromNib we make our self as the application delegate
- in applicationDidFinishLaunching: we tell the application to make
the first window that it finds as main
window, because at this time there is still no main window
- then we create our button instance, set its action as a selector
with our action method, set our self as a target of that action,
and perform all necessary initializations for our button (title, type,
etc)
- we add our button on the main window and then release the button
- in dealloc we remove our self as being application delegate
- okButtonAction: is our button's action method that performs NSBeep()
function
Code follows.
ApplicationController.h
#import Cocoa/Cocoa.h
@interface ApplicationController : NSObject
{
}
@end
ApplicationController.m
#import ApplicationController.h
@implementation ApplicationController
- (void)awakeFromNib
{
[NSApp setDelegate:self];
}
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
[NSApp makeWindowsPerform:@selector(makeMainWindow) inOrder:NO];
NSButton * okButton = [[NSButton alloc]
initWithFrame:NSMakeRect(10.0, 10.0, 96.0, 32.0)];
[okButton setAction:@selector(okButtonAction:)];
[okButton setTarget:self];
[okButton setTitle:@OK];
[okButton setButtonType:0];
[okButton setBezelStyle:11];
[[[NSApp mainWindow] contentView] addSubview:okButton];
[okButton release];
}
- (void)dealloc
{
[NSApp setDelegate:nil];
[super dealloc];
}
- (void)okButtonAction:(id)sender
{
NSBeep();
}
@end
Thanks.

Re: Debugging auto_zone_resurrection_error in Core Data using GCD
I have seen some similar behavior with GCD in GC apps.
It seems that objects created on a separate thread that are then used from
within a block on another thread do not get registered as existing in multiple
threads. When the collector runs on the thread where the object was created it
sees no more references to it and collects it, even though it now exists
elsewhere.
I've only been able to work around it, either by creating the object within the
block, or if necessary calling CFRetain()/CFRelease() on the object immediately
after creating it. As I understand it, CFRetain triggers the collector to stop
treating that address as a thread-local object.
You could also call Block_copy() on your block which should also fix this bug:

Also new interesting data is that even in the -doThatThingTo:attachValue:

*other* example. So it seems like there’s some sort of a delayed response,
like Core Data is storing a weak-but-nonzeroing pointer to the NSDate
somewhere, the object is collected, and later mucking in the MOC exposes the
dangling pointer.
I remain thoroughly mystified…
Thanks for any assistance,

I’m getting an auto_zone_resurrection_error from inside Core Data. Because
this is following switching from locking a MOC on different threads (which
was working fine) to dispatching blocks to a GCD queue, my suspicion
naturally tends towards a multithreading violation. However, I’ve been over
it a million times and just can’t find by inspection any cases of doing
anything in the MOC (including its MOs, obviously) besides on that queue.
Using the debug suffix when loading frameworks (to try to enable Core Data’s
multithreading asserts) dies elsewhere for no apparent reason, not to
mention that I don’t actually see a _debug version in Core Data.framework,
nor see a download to obtain one from connect.apple.com like there was for
10.5.
However, there’s also a suspicious trend in the places that this happens of
it appearing that an object assigned to a local variable or method parameter
outside of a dispatch_sync() is being collected before its use in the block.
In other words, the block’s reference may not be keeping the object alive.
For instance:
- (void)main {
NSDate* startDate = [NSDate date];
/* lots of stuff */
dispatch_sync(dispatch_get_main_queue(), ^{
if(![self isCancelled]) {
MyManagedObject* myMO = self.aRelationship.itsMO;
ourItem.numericalValue = /* a number; this works fine,
so it seems the MO is okay*/;
ourItem.aDate = startDate; /* problem occurs here, and
Instruments suggests startDate is the resurrected pointer */
/* ... */
}
});
}
So,
- What’s the current mechanism for enabling Core Data’s multithreading
asserts?
- Is there a typical, non-multithreading cause for
auto_zone_resurrection_errors inside Core Data?
- Or, are there any known bugs with GC and blocks (or a bug of mine in the
code snippet I gave) causing this?
Some more details, if needed:

Re: Bind to string (path), convert to NSImage
You can bind an NSString path of an image, to an NSImageView. Look up NSImageView bindings in the documentation.

GeekGameBoard (was: Re: Touch-and-drag architecture question)
Thanks, Jens! I'd never heard of this before, and it looks like it'll fit the
bill nicely. However, I'm a total noob when it comes to CoreAnimation, so it
may be a while before I grok what's going on underneath.
As far as GGB goes, how well does it handle custom boards? For example, let's
say I wanted to recreate this board:
http://gallery.me.com/davedelong#100084/Boardbgcolor=black (dots are valid
positions, and lines indicate valid moves between positions).
Presumably I'd be creating a custom Grid subclass and building the board
layout in there. My board is based on a square grid, but I'm not sure how I'd
only make some of the grid positions valid locations, nor how I'd draw the
lines in between them. What would I need to do to recreate this board?
Thanks!

like to be able to drag pieces from these rows onto the board. My question
is this:
How should I set up the view hierarchy to do the drag and drop? As I see
it, there are three main ways:
1. Use different views for the board and the two rows. This is good for
encapsulation, but bad for cross-view dragging.
2. Use a single view for the board and the two rows. This is bad for
encapsulation, but makes dragging much easier.
3. Use different views for the board and the two rows, but have an
invisible view on top of everything that captures all the events and passes
them on accordingly. I'm not sure how this would work out.
Perhaps another important question is: how should pieces be rendered? I've
been drawing them with CoreGraphics (hence the difficulty of dragging them
between views), but I could also make each piece its own UIView (which might
complicate dragging in other ways).
What do you suggest?

problem with distributed objects
OK, I'm back.
I have some distributed object code that used to work just great (back in the
Tiger days, I think), and now does not. I see the error: [NSPortCoder
sendBeforeTime:sendReplyPort:] timed out, when I try to get the rootProxy from
a connection. I see this mentioned here and there on various mailing lists,
but haven't seen any solution.
I need to provide a DO across a network. The simple code Apple provides in the
DO programming guide does work on a single machine:
vend it
/* Assume serverObject has a valid value of an object to be vended. */
NSConnection *theConnection;
theConnection = [NSConnection defaultConnection];
[theConnection setRootObject:serverObject];
if ([theConnection registerName:@server] == NO) {
/* Handle error. */
}
get it
id theProxy;
theProxy = [[NSConnection
rootProxyForConnectionWithRegisteredName:@server
host:nil] retain];
[theProxy setProtocolForProxy:@protocol(ServerProtocol)];
But if one initializes the connection with an NSSocketPort, which is required
if one wants to talk beyond a single machine, the registerName message fails.
So, I whip out the code that used to work. The few relevant parts listed below:
vend it:
conduitPort = [[NSSocketPort alloc] init];
myConduit = [[ServerConduit alloc] init];
conduitConnection = [[NSConnection alloc] initWithReceivePort:conduitPort
sendPort:nil];
[conduitConnection setRootObject:myConduit];
get it:
- (void)netServiceDidResolveAddress:(NSNetService *)netService{
struct sockaddr *address;
NSConnection* theConnection;
NSSocketPort* thePort;
NSSocketPort* socket;
printf(\resolved address\n);
socket = [[NSSocketPort alloc] init];
if([[netService addresses] count] 0){
address = (struct sockaddr *)[[[netService addresses]
objectAtIndex:0] bytes];
thePort = [[NSSocketPort alloc]
initRemoteWithProtocolFamily:address-sa_family socketType:SOCK_STREAM
protocol:0 address:[[netService addresses]

theConnection = [[NSConnection alloc] initWithReceivePort:nil
sendPort:thePort];
[thePort release];
id theProxy = [theConnection rootProxy];
}else{
NSLog(@Could not find an address for the service.);
}
}
When I call rootProxy, I get the time out error. Does anyone have a
dirt-simple sample app I can look at that vends, and gets, a DO over a network
on 10.5 or later?!

My question about this would be whether I would run into any restrictions with the length of the command which well be beyond the old 1024 character limits (not sure if any command line argument limits are still extant). I would think this would be the most efficient way to do it (both time and memory/storage wise), so long as there are no limitations on command line length. Max argv size is defined by sysctl kern.argmax. It's at least 256K these days. I don't think it was ever as low as 1024. Most archive tools have an option that tells them to read file-lists from stdin, one pathname per line. If the archive format doesn't have to be pkzip, then consider using tar and gzip. You could hard-link selected files into a temp-folder rather than copying them. Then unlink when you're done and no copies needed. You can't hard-link symlinks, though, so that may not work. However, pkzip has no encoding for symlinks, so you can't zip a symlink, anyway. Or are you using ditto to write the zip file? -- GG ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Presumably I'd be creating a custom Grid subclass and building the board layout in there. My board is based on a square grid, but I'm not sure how I'd only make some of the grid positions valid locations, nor how I'd draw the lines in between them. What would I need to do to recreate this board? You can create a 7x7 RectGrid and then call -removeCellAtRow:column: to remove the cells that don't appear in that board. You'd also want to set the borderWidth to 0 in the remaining cells so they don't draw their square outlines. Alternatively, you could just start with an empty board and add a BitHolder object for every valid position. Drawing the background lines is up to you. You could create a fancy image of the board and add it as a PNG file, or you could make a CALayer for the background that has a custom drawing callback. —Jens___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Bind to string (path), convert to NSImage
You can bind an NSString path of an image, to an NSImageView. Look up NSImageView bindings in the documentation. Also it seems like bad practice to have the at-symbol inside your NSDictionary key strings. For example make sure you use @iconpath instead of @@iconpath because that at-symbol could eventually conflict with Apple's own collection operators. -Steven 2010/2/15 Trygve Inda cocoa...@xericdesign.com I have an NSImageWell (or NSView). I am using an NSCollectionView and have it bound to an ArrayController which is bound to an array of NSDictionary. The dicts have several keys, among them @name and @iconpath @iconpath is a NSSting that contains a path to an NSImage. How can I bind though my NSArrayController, but have code that converts my path to an NSImage to return to the view inside NSCollectionView Obviously I know how to derive the NSImage from the path, but since the NSImage in not in the array of dicts, how can I bind it? I basically need the system to call a method I write to take a path and return an NSImage. Actually the @ is not in my names - not sure why I wrote it out like that.

will this window not overlap my NSPanel and will remain this my panel
still on top. This is correct functionality ! :) But .. this function
showModal is called multiple times during runnig my application, and
this NSPanel is multiple showed and closed. But only first calling of

What i do wrongly and why is not my NSPanel in Modal status after

The proper way to end a modal session within the modal event loop is
to use -stopModal or -stopModalWithCode: . Try that and keep the -

Re: NSView : Background bitmap drawing issue
While there could be a drawing but in the OS, it's probably best to
rule out issues with your code first. How do you determine the OS
version? I ask because that's the only version-specific test in your
drawing code. I would do something like this to initialize the
variables:
double majorOSVersionNumber = floor(NSAppKitVersionNumber);
isLeo = NO;
isSnowLeo = NO;
if (majorOSVersionNumber NSAppKitVersionNumber10_4)
{
if (majorOSVersionNumber NSAppKitVersionNumber10_5)
isSnowLeo = YES;
else
isLeo = YES;
}
You should not being doing tests like if (NSAppKitVersionNumber ==
NSAppKitVersionNumber10_5) since that will only be true for 10.5.0,
but will fail for 10.5.1, 10.5.2, etc. The value of
NSAppKitVersionNumber is incremented by an integer amount for 10.x
releases and by a fractional amount for 10.x.x releases.

Re: Null value from NSMutableArray
You could expect to see zero/nil values returned from object
properties if the object pointer is nil. Adding
NSLog(@%p, fooObj);
would tell you if that's the case.
Also, I'm not sure how your question relates to NSMutableArray since,
at least in your code snippet, you don't do much with it.

I've used a code from the Net, which adds a category to NSApplication. This
code was tested in both 10.4, 10.5 and 10.6 and works perfectly. No problems
here. Moreover, I've changed the drawing code to make it to be more clear.
My initial goal was just to draw the upper part of background image (the
same for several windows), whereas windows have different height. Therefore
I calculate an offset value, which is used in setPatternPhase, as
[myView bounds].size.height - [myBgImage size].height
And I've tried to exclude version checking from the code. A person, who
reported a bug in 10.6, now tells that all is OK. But I've tested this
version in 10.6 and in 10.4 and in both versions there is a shift for 1
pixel down. It looks like my NSView is shifted for 1 pixel. But its frame
top is zero. Its height is the same in every OS... Just a weird problem...

I can't really follow what this code is supposed to do. fooObj is a 'blank'
object, whose properties don't get set to anything, but you print out its id
and name property every time through the loop. Did you mean to use obj instead
of fooObj in the last two NSLog calls? In that case, what's fooObj for?
Also, it's a heck of a lot easier to iterate over an array by using
for (id obj in fooArray) { ... }
unless you need your app to remain compatible with the thirty-two Mac users who
still run 10.4.

valueForUndefinedKey confusion

confused as to what's going on.
NSLog(@Total number of components in work: %i, [AllComponents count]);
for(NSString* cKey in AllComponents)
{
NSLog(@key? %@, cKey);
MnSComponent *comp = (MnSComponent*)[AllComponents valueForKey:cKey];
[comp buildPitchMatrix];
[comp calculateTension];
}
The NSLog prints the expected key, then the code gags on the next line. ???

Try -objectForKey: instead of -valueForKey: there might be some subtlety of use
KVC versus direct access that's screwing things up here. The key might contain
characters that can be misinterpreted by KVC - containing '@' or '.' characters

Also, are you certain that buildPitchMatrix and calculateTension are not

As expected, you are a rock star, Graham.
(and no, the following methods don't muck with the dictionary - it's obviously
some subtlety in KVC... There is an underscore in the key string, so that
probably borked it.)

Dear XCode folk, I'm sure this is obvious but it's got me stumped and googling has produced no solutions. The program always runs with the debugger when I launch with xcode (3.1.4). It doesn't matter if I pick build and go or go; the debugger always launches. In previous versions (2.5) I was able to run w/o the debugger. In general, It's too slow with the debugger up and going for a lot of my debugging work. Is there a way to run this w/o putting it through the debugger? --Matthew ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Ignore last message...
The XCode problem was solved. Guard Molloch [sic] was the culprit. --Matthew ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: NSPanel and runModalForWindow: problems
Ok, so .. at the end I managed to find the correct solution
-(void) showModal
[myWindow setLevel: NSStatusWindowLevel];
[myWindow center];
[myWindow orderFront: self];
}
-(IBAction)delayWindow:(id)sender {
[myWindow orderOut: self];
}
also thank those Keary Suska, that he brought me back on track :)

I have a NSPanel that is opened like Modal panel:
-(void) showModal {
[NSApp runModalForWindow: myWindow];
}
and is closed with event click on button that is allocated on this
NSPanel:
-(IBAction)delayWindow:(id)sender {
[NSApp abortModal];
//[myWindow orderOut: self];
[myWindow close];
}
First calling of runModalForWindow: works fine and NSPanel is in
modal status but after calling delayWindow and after then second
calling of showModal is NSPanel correctly showed but is not in
Modal status :(
What i do wrongly and why is not my NSPanel in Modal status after
second, third etc. calling of showModal ?
The proper way to end a modal session within the modal event loop is
to use -stopModal or -stopModalWithCode: . Try that and keep the -
orderOut call (not because it is necessary, just that it is a good
practice for windows you know you will re-use without re-loading).

Getting a stacktrace on 10.5
I am building on 10.6 and targeting 10.5 deployment. I pick up exceptions and log the stacktrace using callStackSymbols if it is available (10.6) - this works fine. On 10.5, if the user has the developer tools installed, I can use the atos command to get the trace, but if they haven't is there any way to get a stacktrace on 10.5? I have tried the backtrace_symbols method, but that doesn't seem to give me anything useful. Is there some other way of doing this on 10.5? Are there compile options that would get backtrace_symbols to produce something useful? If so, what would be the impact of using them?

IKImageBrowserView vs NSCollectionView and scaling
Is there any nice way to get NSCollectionView to scale its images the way IKImageBrowserView does? It is much easier to customize the item views with NSCollectionView and the only thing really lacking is scaling of the subviews... It also binds a lot nicer than IKImageBrowserView.

Refresh com.apple.symbolichotkeys.plist
Hi list, Is there any way to cause the system to re-read com.apple.symbolichotkeys.plist.plist in Cocoa (or anywhere else)? I want to programmatically change a shortcut (which is no problem), but I want it to take effect immediately. System Preferences obviously signals the system to do this - does anyone know how it does that? Thanks!
