scaling a transformed view
Hi, I've come upon a problem i can't seem to get my head around. I have a view that has a rotation transform on it and i need to be able to pull at one of it's corners and scale the view based on the amount pulled. I also need to keep the opposite corner of the pulled corner pinned to it's location. Does anyone have any pointers or sample code that might point me in the right direction? thx AC___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: inter-process locks
Yeah, that seems like a good option but since its based off of flock, it has the same issues. Things like apps crashing or not unlocking by error will prevent other processes from obtaining the lock even though the lock is not 'really' in use anymore.

Hi, I have a specific layout that has known font sizes for certain page dimensions. I need to take that layout and resize it to fit it in multiple different places in my app. I can't just apply that resize ratio to the fonts, it just does not work. Is there a known way in cocoa to figure out the correct ratio for a font when resizing it so it fits within the rest of my layout and gives me same look but resized. I could just create an image and resize that and display it in a ImageView but this seems to me like a waste of resources especially when ported to iOS.

Thanks Nick, this will help a lot, i don't think its explained anywhere in the docs. You are spot on for why i need to do it.

NSView alphaValue animation on 10.5
Hi, I've got a lot of code that depends on 10.6's use of NSView's animator and setAlphaValue for showing and hiding animations. Now, i need to bring this to 10.5. On 10.5, to animate the alphaValue, i learnt that the NSView needs to be backed by a layer. I tried doing that and it created mayhem, so i don't think i can go that route.

Not responding in activity viewer
Hello,
I've got a very simple launch Agent that always shows up as not-responding in
the activity monitor on 10.4 and 10.5 This is issue does not happen on 10.6.
The app is very simple and does not do much. It has no UI but does link against
Carbon since it uses GetNextProcess. It has 2 threads, the main thread which
pretty much just sits there in the main runLoop, and the other that does some
work then sleeps for 2 seconds and repeats.
Here some code:
void*
otherThread()
{
while (1)
{
doSOmeStuff()
sleep(2);
}
return NULL;
}
int
main( int argc, char* argv[] )
{
NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init];
startOtherThread();
[[NSRunLoop currentRunLoop] run];
[pool release];
}
Any ideas why my app appears non-responsive to the activity monitor?
thx

Re: cross-process file open notifications
I can't put any code into the dylib. It's library that's not being developed anymore but many users have it and use it. We have a new approach but the dylib has a sort of lock on some things we need. Because of this, we've decided to watch for usage of this dylib and when there is no usage, we can enable our new approach. As of now, all i can do is poll for new processes and run lsof on the to see what files they are using. I consider this approach very bad but i can't think of anything better.

So i guess my question is what is the corect way to wait in the main thread without stopping the NSRunLoop? It's actually wrong (in most cases) to wait in the main thread at all. Blocking the main thread prevents events from being handled and results in the dreaded beachball cursor. What you should be doing instead is structuring your code asynchronously. Set up the callbacks, then keep the app running normally and handle the callbacks when they occur. It's definitely a bit more complex to code this way, but it keeps your app responsive while avoiding the greater complexity of multi-threading. 100% agree with you, and that's what i would normally do.

No, you're barking up the wrong tree. There's no "how @dynamic works". @dynamic is a compiler directive telling it that getter/setter method implementations exist, but just not in the current compilation unit. There no standard general mechanism for supplying the implementation. In the case of Core Data specifically, the built-in implementations (call them "dynamic" if you want, but that's the same as their being compiled as "@dynamic") are simply efficient versions of what you would otherwise have to hand-code. We don't know if they're funneled through one funnel, several funnels, or a different function for every property -- that's an implementation detail. (IAC, Core Data doesn't mark objects as changed in *those* dynamic methods, but (presumably -- another implementation detail) in the primitive dynamic methods.) I don't how you're ever going to be able to have a class detect invocations of its subclasses' properties, unless you have the class muck around in the runtime, replacing methods on the fly. A better solution, IMO, is to realize that you're considering a design requirement for your data model, and to design the solution right into the model. For example, if this is a self-contained class hierarchy that you're implementing, you could make it a requirement of subclasses that they invoke something (a superclass method) or inform something (a controller of some kind) when they modify data values. I'm with you. I've realized that's the way to go. Concerning CoreData, i was looking for info or ideas on the implementation details. thx for the info.

Re: watch changes to any properties on an object
Overriding willChangeValueForKey: was one of the first things i tried before posting and I noticed it was not being called, i thought it was weird but nothing more. Good to know that overriding it was deprecated. Thx for the info on how CoreData manages it's saves. I was hoping to not have to create setters for all the values that can change my dirty flag but i guess ill have to. I guess what i'm looking for is a method like setSelector:forChangesOnProperties:. thx AC On Sep 3, 2009, at 3:30 PM, Ben Trumbull wrote: Well, @dynamic doesn't have anything to do with KVO. It's just storage and accessors for properties. Core Data knows when non- dynamic modeled properties change too. It sets a dirty flag, just as you would have to. Most of that happens in - willChangeValueForKey:. Unfortunately, overriding that method was deprecated in 10.5. KVO no longer guarantees overrides will be called. In terms of knowing what to save, Core Data only tracks that at an object level, and uses snapshot deltas to compute the changed property set at the end. Some people invert the observing relationship to work around this. You can add code in your setters to set a dirty flag, or within your setters manually call a notify method on another object. If you have fewer objects, you could just use NSNotifications. Almost certainly worth filing an enhancement request at bugreport.apple.com - Ben Ok, thats what i thought. But just for implementation ideas, how does CoreData know when one of it's @dynamic properties is changed? It must set some sort of flag somewhere in order to know what to write out when it needs to save.

To do inter-thread messaging using only low-level frameworks, you are stuck with the traditional facilities (socket, pipes, etc.) Just by curiosity, what prevent you to use the Foundation framework ? I'm in some C++ code and cannot use Foundation, only CF. I did find a solution though. The solution is to create a RunLoopSource and pass it an object ( C++ ) that knows what function to call in it's context.

NSArrayController and moving around its contents.
I have a custom view that pretty much shows an ordered list of items in a grid ( kindof like iPhoto ). This custom view exposes a content binding. Items in this grid can be reordered by drag n drop. Then this occurs, i have an NSIndexSet of selected indexes and a drop index where i need to move all the items to. Whats the best way to do this? If i just had a normal array, it would be easy just by removing and adding them back in the right place. But with the array controller, if i remove then add back in i get two content changes which could possibly make the view flickr since on content changes, there is some fade in and moving animations.

NSArray represented in 2 different views at same time
Hi, I've got a list of objects in an NSArray and i'm currently managing them with an NSArrayController and a view that is binded to it. Now i need to be able to show that same view in a new window with the same content but with possibly different selections and sort descriptors. I also need to update the content display in both views when an item is added or removed. I guess the closest approach i can think of is iTunes when you double click an item in its source list and it opens up a new window with the same content. My question is how should I approach this. Should i have an array controller for each view and have them notify each other of changes? Does anyone have any experience with this sort of workflow and if so, how did you manage all of this. thx AC ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Cover Flow in Cocoa?

I wouldn't use that in a serious app, as it could change incompatibly or be taken out in any future OS release. (The former is quite likely: a primary reason why frameworks or classes don't get made public is that Apple hasn't polished their APIs yet. Making something public involves committing to supporting binary compatibility with it, which really limits what you can do with the API, and Apple doesn't take that lightly.) I agree with you on that. The only reason i would see for using them is that the CoverFlow Private API is pretty much interchangeable with the ImageKit Browser API. This does at least show some sort of consistency and might point to the IKImageFlow being made public soon (I hope).

[OFF] unicode characters
Sorry for the off-topic post but this is the best place to get info ( lots of smart people ). I have a string that is composed unicode characters. I want to be able to transform that string into all ascii characters by transforming all non-ascii characters into their ascii equivalent. ex: ü = u é = e Anyone know of a way to do that or do i need a lookup table with all characters and their equivalents? thx AC___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

DO problems
Hi, i have a server and client communication through DO. Connections are all set up then the client send a message to the server with itself as the first argument. The server should then just reply right away to the client using the first argument as the proxy. Problem is, im getting the error below when trying to send the response form the server back to the client. Any ideas what might be happening? server received hello *** NSDistantObject initWithCoder: 0x2 not given away for conn 0x171a62f0 exceptionHandler:shouldHandleException: -[NSConcretePortCoder decodeInvocation]: no local target thanks AC ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: memory warnings
Thanks, ill look into this. Its much better than nothing.

It might be telling you about physical RAM, not process address space, which are both interesting but have different failure modes (VM thrashing, failures in malloc).

If you're using Leopard, then consider releasing a 64-bit version of your application. If you're using Tiger, then consider using the NSZone API with zones that will not grow (zero granularity). Then, if object allocation isn't working, then at least your app won't crash. Either way, if your app creates lots of temporary objects, then you should wrap them in NSAutoreleasePools.
