NSDrawer contentView clip
I have put some buttons within a drawer.contentView The top most button gets cut by 20 pixels because the contentView result shorter than its superview height. So, at the top of the drawer I always see a gray rectangle, 20 pixels height, where I can't draw in. Please, how can I use the whole height of the drawer height? I unsuccessfully tried to subclass the contentView and return different frame and bounds values, also returning bigger values with drawerWillResizeContents but, no way. It seems that the contentView gets clipped by its superview. Any solution?

Re: NSError help
Thanks,
Yes, the compiler was complaining about the "*err = *localErr;". I origionally
had it to be "*err = localErr;" but I was still getting a EXC_BAD_ACCESS error.
But then the light bulb went off :-)when I read "he isn't checking for nil
err", and that is exactly what was my problem.
I changed the code a bit per your suggestions.
return [self getDataForType:aType separator:@"\t" excludeFields:nil error:err];
But the other change I had to make was
if(err) {
NSMutableDictionary *errorDetail = [NSMutableDictionary dictionary];
[errorDetail setValue:@"Failed to find the requested type."
forKey:NSLocalizedDescriptionKey];
*err = [NSError errorWithDomain:@"DataForType" code:1 userInfo:errorDetail];
}
return nil;
Thanks for the help,
tom

This is incorrect. The left and right sides are of two different types. The
compiler should have at least warned, if not given an error.
"*localErr" is an NSError. It's not an NSError* (pointer to NSError), it's
actually the type of the object (or struct). There's almost never a case to
dereference an object pointer like this.
"*err" is an NSError*, a pointer to an NSError.
What you wanted is:
*err = localErr;
Actually, if you're not doing more with localErr, you can just eliminate it and
just do:
NSString *result = [self getDataForType:aType separator:@"\t"
excludeFields:nil error:err];
The same mistake affects the next method, too.

I solved the issue on Mac OS X 10.6 by calling lockFocusOnRepresentation: and unlockFocus before and after I refresh the bitmap buffer. Funnily enough, this bug also exists with the CoreGraphics API. Hi- This isn't a bug, and your workaround could break under you at any time. If you think about what has to happen, you'll realize you cannot just have permanent direct access to the backing store. The image has to be colormatched and possibly uploaded to the graphics card, for example. How are the frameworks to know if you toggled a bit and that work must be redone? The basic CG model for an image is that it's immutable. Thanks for the hints. I tried them this weekend. When working with NSBitmapImageRep, calling -bitmapData is a signal that you may be editing the data. It is not repackaged until the bitmap is drawn, or somesuch. It's illegal to just stash a pointer to the data and use it arbitrarily later - that won't necessarily be the same data as now backs the image. This is described in the 10.6 AppKit release notes. Calling -bitmapData works on Mac OS X 10.5, it does not work on Mac OS X 10.6. On 10.6, it's slow and the data gets zeroed. Bug? In CG, you may be interested in the relationship of CGBitmapContext to CGBitmapContextCreateImage. The latter makes a copy-on-write vm copy of the data from bitmap context. So it's cheap until real copying is forced by a write to the context data. I tried this solution and it's way too slow (or I'm doing it incorrectly). Having to create a CGImageRef and then releasing it is killing the framerate. Basically, the only solution to get a decent framerate (25 fps) and a real refresh is to: - call -bitmapData on Mac OS X 10.5. - call lockFocusOnRepresentation: on Mac OS X 10.6. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Thread not registered mystery under GC
Hey guys, hopefully someone who knows what may be going under the pthread/NSThread hood when GC is enabled can solve this little mystery... Pretty straightforward situation: I have a 64 bit Cocoa app (and screen saver) that uses pthreads (via the pthread API, *not* NSThread). To be compatible with GC with IAW with Apple's GC Programming Guide (quote below), I make a call to [NSThread currentThread] when a new thread starts so that it gets registered with the GC subsystem. Per Apple GC Programming Guide (page 15): // SNIP // Garbage collection is performed on its own thread--a thread is explicitly registered with the collector if it calls NSThread's currentThread method (or if it uses an autorelease pool). There is no other explicit API for registering a pthread with the collector. // SNIP // However when my bundle runs under as a 64 bit GC app or a 64 bit screen saver (via the sys prefs app), the following log msg shows up for each call to [NSThread currentThread] I make when the thread first starts: [0x0-0x8b08b0].com.apple.systempreferences[1198]System Preferences(1198,0x11a8f9000) malloc: *** auto malloc[1198]: error: GC operation on unregistered thread. Thread registered implicitly. Break on auto_zone_thread_registration_error() to debug. As the message directs, I set that breakpoint, and I see the following stack inside of the [NSThread currentThread] call: #0 0x7fff81b08c64 in auto_zone_thread_registration_error #1 0x7fff81b089aa in Auto::Zone::registered_thread #2 0x7fff81b01df0 in auto_zone_allocate_object #3 0x7fff85c8602a in _internal_class_createInstanceFromZone #4 0x7fff866d56e9 in +[NSObject(NSObject) allocWithZone:] #5 0x7fff866d5671 in +[NSObject(NSObject) new] #6 0x7fff88e553b5 in _NSThreadGet0 So, it seems like I'm following the spec yet I can't seem to shake that error message. Anyone on the inside care to illuminate what's happening here? Apart from those [NSThread currentThread] calls I make when the pthread first starts, is there something else I need to call that the GC spec doesn't discuss? Thanks in advance!

Drag and drop between two table views.
I am trying to drag and drop from one text view to another. I can write an
index set of copied rows to the pasteboard using:
- (BOOL)tableView:(NSTableView *)tv
writeRowsWithIndexes:(NSIndexSet *)rowIndexes
toPasteboard:(NSPasteboard*)pboard {
// Copy the row numbers to the pasteboard.
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:rowIndexes];
[pboard declareTypes:[NSArray arrayWithObject:NSDragPboard] owner:self];
[pboard setData:data forType:NSDragPboard];
return YES;
}
In the array controller for the destination text view, I have
- (BOOL)tableView:(NSTableView *)aTableView
acceptDrop:(id )info
row:(NSInteger)row
dropOperation:(NSTableViewDropOperation)operation
{
NSPasteboard* pboard = [info draggingPasteboard];
NSData* rowData = [pboard dataForType:NSDragPboard];
NSIndexSet* rowIndexes = [NSKeyedUnarchiver unarchiveObjectWithData
:rowData];
NSInteger dragRow = [rowIndexes firstIndex];
// Move the specified row to its new location...
NSLog(@"count = %i", [rowIndexes count]);
while(dragRow != NSNotFound)
{
NSLog(@" %i", dragRow);
dragRow = [rowIndexes indexGreaterThanIndex:dragRow];
// Copy a row here.
}
return YES;
}
I'm having trouble figuring out the correct code in the while-loop where I
need to copy a row.
As you can see, I'm new at this, but perhaps someone can lead me in the
right direction. Thanks.

Move UINavigationBar down?
I'm trying to position the navigation bar below the top of the screen. I've tried the following in viewWillAppear: self.navigationController.view.frame = CGRectMake(0.0, 54.0, 320.0, 426.0); self.navigationController.navigationBar.frame = CGRectMake(0.0, 0.0, 320.0, 44.0); The problem is it only seems to work the very first time the view is displayed. If you go to another tab, and back, the navigation bar is at the top of the screen. This also happens when the iPhone is rotated. Should I be trying to adjust the navigation controller frame, or should I instead try to add the navigation controller to another view that is below the top of the screen?

Yes. Call objc_registerThreadWithCollector() from the thread. The behavior was changed because folks were surprised to see the collector being registered on their thread when they were "only" using Core Foundation code and "no Objective-C". Core Foundation is actually implemented using a growing chunk of Objective-C code. Thus, the collector became noisy about this so people wouldn't be surprised -- or, more importantly, would be surprised but would figure out what is up more quickly.

Few binaries in one application's Bundle
Hello My project consists of few binaries, and i wanted to put them into one application Bundle (thus, i placed them into ./Contents/MacOS/). Only one of these binaries is launched when the bundle is doubleclicked in finder (i have specified it in ExecutableFile in bundle's Info.plist file). Other binary files - one is an agent that is started with launchd, and one auxilary GUI application (that is launched either by the agent, or by main binary). The problem is, when either one of binaries is started, no one else from this bundle can be launched. The bundle itself is "LSUIElement=TRUE". I was wondering, if i could use some technique/non-evil hack to keep my appliations in a neat one bundle (counting that the user should be able to start only one main binary, while other binaries are started automatically by agent or by the main application). I'm thinking that this would be convenient for the user - if he is annoyed by my app, he just moves my bundle to a trash bin, and the job is done :) Thanks! ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Have you tried adding a "Custom Executable" to your framework target that points to the application that uses your framework? Then you can choose "Debug" in the framework project and it'll launch your app and you can have breakpoints. PS - I just saw your second post, a mere 3 hours after the first one.

This is totally confused and broken.
The rowIndexes just tell you which rows to copy; they do not contain those
row's data. You can use the indexes in the index set to find out which data
items in your data model you want to copy to the pasteboard. You are archiving
the rowIndexes themselves, which information is unlikely to be of much interest
to the destination.
Once you have the actual data, you write it to the dragging pasteboard using an
appropriate type. For private data of your own, you need to make up something
suitable for the type - NSDragPBoard is NOT a type name, it is a pasteboard
name and should not be used here.

Same error here, NSDragPBoard is NOT a type name. This should be whatever you
used in the write method, and for private data is a name you made up. Note that
for some kinds of data there are suitable predefined type names but if you use
those you have to ensure that the data is written in the appropriate format.

Because you archived the source table's row indexes rather than the data they
index, that's what you get back. At this point that information only makes
sense in the context of the source table. While that can be made to work (as a
private transaction between data models in your app, you could have the second
table ask for the data from the source here, but it's more conventional to pass
the data itself, so you have it already here, where it's needed).
If you can fix up these issues, putting the data into the destination is a case
of inserting the data items at the row you're given and calling -reloadData on
the table so that it draws the updated table.
I should factor out the data movement or copy into methods on your data model,
e.g. [myDataModel dataForIndexes:(NSIndexSet*) indexes] and [myDataModel
insertData:(NSData*) data atIndex:(NSUInteger) index]; so that you have a pair
of simple methods you can call from the table's drag/drop handling methods.
Since they are views they should not be making too many assumptions about the
data they are displaying.
I assume you have also registered the destination table view to receive drags
of the desired type? Since you have not used a correct type name I suspect that
step is also missing.
