Plugin Information
Hello everyone, My application uses plugins from a support folder in /Library/ Application Support/AppName/Plugins/. The application searches this folder for all the plugins and loads them. But here is my dilemma: i want to put the plugin class name as the bundle identifier so that i can call methods from those classes when something in the main application is triggered. For instance, I have a plugin called A.plugin, B.plugin, and C.plugin with Principal Classes named APluginClass, BPluginClass, and CPluginClass respectively. They conform to AppNameProtocol which has an installation, allocation/init, dealloc, and other class names. My code uses NSString *bundlePath, and NSBundle *bundle. I want to have something like *bundlePathA, *bundlePathB, etc; and *bundleA, *bundleB, *bundleC. Is there a simple way that I can do this? I have researched NSBundle on the Developer docs, and on apple.com, along with some code on google.com/codesearch . Can anyone give me a pointer or two?

Use variable names that are defined at runtime? You should already know that this is nonsensical in C. I think you're really looking for a mapping from bundle identifier to class instance. That already exists. Once you've loaded the bundle, you can use +[NSBundle bundleWithIdentifier:] to get it again elsewhere, then use -[NSBundle principalClass] to get its principal class. Then +alloc/-init as normal. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

You're not really making sense here: You can set the bundle identifier in the Properties tab of the Target Info window in Xcode. There's also a field for the principal class name. You really do not want to force the bundle identifier and class name to be the same. That's not the purpose of these two fields. The bundle ID is for uniquely identifying a plugin, not just across all plugins for your app, and not just across all developers who might write plugins for your app (so that e.g. Microsoft's 'Load WMF file' plugin can be distinguished from your own), but also across all plugins on a particular Mac, no matter what app they're for. Using a class name as a bundle ID is asking for collisions, and someone is bound to look up the wrong bundle and try to load the wrong kind of file. Don't abuse the bundle ID. For instance, I have a plugin called A.plugin, B.plugin, and C.plugin with Principal Classes named APluginClass, BPluginClass, and CPluginClass respectively. They conform to AppNameProtocol which has an installation, allocation/init, dealloc, and other class names. My code uses NSString *bundlePath, and NSBundle *bundle. I want to have something like *bundlePathA, *bundlePathB, etc; and *bundleA, *bundleB, *bundleC. Is there a simple way that I can do this? Do what? If you mean, look up a bundle based on its class name, then you can use an NSDictionary to associate class name with NSBundle objects. This also works for the other way round, but in that case you could just use the principalClass method of a particular NSBundle object. Does that help? If not, it may help to illustrate what you're having trouble with by giving us more information, in particular giving us a concrete example of what you're trying to do, plus maybe even code that illustrates the problem.

I thought there was a flag to get this behaviour automagically, but I can't find it right now. Maybe I just wrote a custom subclass that has this feature and forgot about it. Others have already warned you about not covering up the dock because users get annoyed when that happens. But I guess if you're trying to do some graphical overlay or full-screen app it may be OK. Though in the case of a full-screen app, you may want to check out hiding the menu bar, that usually also hides the dock, IIRC, and fixes the issue in a much more elegant way. There's also a special kiosk mode for full screen apps that may be used to implement behaviour many full screen apps need.

First, unless your window does not need to be clickable or visible at all, don't do this. Pro Tools doesn't move when the dock pref is changed, and it annoys the hell out of me, especially when its resize widget is behind the dock. If you do have a good reason (which I can't think of), then try setting your window's level to be below that of a normal window, like 0, and see if that does the trick. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Howdy,
I have a matrix of radio buttons that I'm trying to bind-ify. The two
options in the matrix should shown with the titles:
Mac OS Extended
Mac OS Extended Journaled
The *values* of these two items should be:
HFS+
Journaled HFS+
Then what I'd like to do is bind the selectedValue of the matrix
(which would be either HFS+ or Journaled HFS+) to a string
property in my model.
I can bind the content of the matrix to my model's diskImageFormats
key path which would be:
- (NSArray *)diskImageFormats;
{
return [NSArray arrayWithObjects:@Mac OS Extended, @Mac OS
Extended (Journaled), nil];
}
...and that properly sets the titles of the two buttons, but the
values are still the titles. So I *thought* could simply bind
contentValues to another key path such as:
- (NSArray *)diskImageFormatValues;
{
return [NSArray arrayWithObjects:@HFS+, @Journaled HFS+, nil];
}
...but this doesn't work, because apparently the key path of
contentValues must have the content key path as a prefix, such as
diskImageFormat.value which entails a certain organization that
seems to be too far off from what I need.
Is there a way to do what I want to do?

Huh. I wouldn't expect it to do that given that it's borderless.
How can I bypass this behaviour for my window?
Should I use applicationDidChangeScreenParameters and reposition the
window, or is there an option to make my window not care about the
Dock appearing?
It'd probably be easier to just override setFrame in a window subclass
and make sure it's always what it should be. Just a thought.

Naturally, right after I gave up on solving it for the night, I guessed the
solution.
I figured I'd reply to myself and say that, to save others the trouble of
trying.
It was indeed something embarrassingly simple: I had accidentally created a
method with the same name as an accessor which otherwise would have been
autogenerated, overriding it. Changing the name of that method made it all
work.

NSTableView memory usage
Hi, I have a NSTableView object with 3 columns and an average of 30 characters per cell. At 1500 rows, “ps –A -u” reports it uses 39.0% memory (there is 1GB of memory on this Mac). After the panel containing the NSTableView is closed, the app uses 1.8% (just as before opening it). The panel in question doesn’t have anything else on it … So is this a major memory leak or a normal situation?

Re: Why should we set ivars to nil in dealloc?
OK. My $0.02 To answer the original question... We live in an Object world, where we like to re-use things. So, for example, I have an object hierarchy of view controllers. In -awakeFromNib:, I use a instantiate and use a iVar. In dealloc, I release it. However, under the covers, I DON'T call [super -awakeFrommNib:], because my parent didn't awake from his .nib. But, in dealloc, I call [super dealloc], so my parent gets called (and eventually NSObject) Assuming that, in his awakeFromNib:, my parent used the same iVar (or more correctly, I'm re-using it), he too will release it, which is BAD. So, he needs to check if it's nil before releasing it (yes, Obj-C will ignore the release to a nil object), and thus, more importantly, and to the question at hand, I need to set it to nil, in my dealloc, when I'm done with it. Technically, you got the ivar nil-ed out, and it's good form to put it back the way you found it.

mouseMoved: behaving correctly when application isn't frontmost
Hi all, Our application it setup to forward all mouse moved events to our content view, regardless if our application is the frontmost one. Now, we have some areas of the content view that are to be highlighted when the mouse hovers over them. This works ok (with work, I mean it looks acceptable) if the area in question is fully visible, e.g. our content view and the tracking area are not covered by another window. What does not work is when the tracking rect is partially covered - it looks strange if the mouse pointer is hovering over another window covering our window, and we start highlight stuff in our window... Get me? To see what I mean (and how I want to solve the problem); open up Safari (i have 3.1 installed). Make sure that you have a couple of bookmarks in the bookmark bar. Now, make another application the frontmost application. Move the new application's window so that it partially covers one of the bookmark items. When hovering over the (now inactive) Safari window and the partially covered bookmark item, the item will highlight while the window directly under the mouse pointer is Safari - otherwise it does _not_ highlight. How can you tell, inside mouseMoved: or similar, if the window beloning to the view isn't covered by another window where the mouse pointer currently is?

Re: A question about Tabviews and tabview items
You and one other both made this suggestion to me and examining it, it is certainly the easiest and most logical way to go. Which is probably why it did not occur to me. Thank you very much for your suggestion, I think this is the approach I will use.

Rather than subclassing NSTabView (since it does not really expose any mechanism to override tab drawing), custom tabs can be implemented by hiding the NSTabView's tab buttons and utilizing a completely separate custom tab bar view containing your buttons. The custom view would then oversee the actual NSTabView's selection, set as its delegate to monitor outside selection changes, and would itself switch to the proper NSTabViewItems when clicked.

Re: Menu items vs modal sessions
Thanks for the insights Keary. I did indeed expect to get some of the behavior for free, but didn't. This is probably due to the fact that I am using bindings to bind menu items to controller actions. I guess one gets the free behavior only when using target/action connections on the first responder. Maybe the right way of doing things with bindings is to put the controller into an NSObjectController and pull it out / swap it when a modal window comes up. This would approximate the responder chain logic. Best, Pierre On 13 Apr 2008, at 21:25, Keary Suska wrote: If you already get certain behavior for free, why complexify it needlessly? What problem are you trying to solve? If you have menu items that are enabled during certain modal sessions, and you specifically don't want them to, then you should look at your application design and adjust accordingly. So, I guess to answer your questions, I would say, probably not. Better to follow the ways that AppKit wants you to do things (such as intelligent use of the responder chain), rather than jerry-rig a band-aid solution. --- Pierre Bernard http://www.bernard-web.com/pierre http://www.houdah.com smime.p7s Description: S/MIME cryptographic signature ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: HUD-style panel controls?
Jacob, You may want to look at applying one or more of the numerous filters available to you when you make your controls layer backed. I did this with most of the controls in my HUD for an image editing application and it works just fine. Color Monochrome is your friend! Using filters avoids all of the hueristics of modifying controls to use custom imagery. Note: Applying a filter to most text will product crappy-looking text. In my case, I simply used white text. later, douglas On Apr 12, 2008, at 10:01 PM, Jacob Bandes-Storch wrote: I'm adding a HUD panel to my application.

If your superclass expose an instance variable for connecting objects in IB, you should trust that it deals with them in dealloc. Directly accessing the instance variables of another class, including your superclass, is fraught with peril and typically incorrect.

You might only expose the name property of an object in the table view, but the object itself could of course have a ton of other properties that uses up a lot of memory. As you get back the memory when you close the panel, it doesn't sound like you have a memory leak per se.

Re: NSDateFormatter giving different results in different programs
On Apr 13, 2008, at 11:21 PM, Derrick Bass wrote: In one program that links to this framework, the date is getting parsed correctly. But in another, the very same string is coming back as 1969-12-31 16:00:00 -0800! Using - [getObjectValue:forString:range:error:] gives the same results no error. What could be causing the different behaviors and how do I get the string to parse no matter what? There are two styles of NSDateFormatter: The pre-Tiger style (10.0) and the Tiger later style (10.4). The latter supports non-Gregorian calendars and automatically fetching properly localized date formatters, but when parsing strings into dates, they require the format to be extremely strict or they don't work. The former only supports the Gregorian calendar, and the methods of getting properly localized date formats have been deprecated, but they are much more flexible in the kind of input they take. So make sure both formatters are of the 10.0 style.

Forced Refreshing of WebKit
I have a product that uses a WebView to display HTML to the user. At times, due to activities spawned along with updating the HTML data to the WebView, response times can be a few seconds. It would be a better user experience to see the updated view displayed before other activities are finished. While many other types of views can be forced to immediately redisplayed via [... display], WebView appears to not immediately update, preferring instead to update after the current event is processed. Is there a means to have a WebView update immediately instead of waiting for the normal drawing process? Thanks!

Is that how I was suppose to drop it on Script Editor? Scriptable applications provide what are known as dictionaries of their terminology. You can open an application's dictionary using the Open Dictionary item on Script Editor's File menu. Under the hood, AppleScript is just a human-readable representation of Apple Events, which are the primitive IPC mechanism on Mac OS (well, if you don't want to talk about kernel-level IPC through mach ports or BSD-layer IPC with pipes and sockets, that is). Apple Events are somewhat analogous to Windows messages like WM_CLOSE, but they are a lot more structured and versatile. When you right-click and application's Dock icon and click Quit, for example, the OS is actually sending that app a Quit Apple Event. This is just like when you quit an application from the Task Manager in Windows (in that case, Windows posts a quit event to the app's message queue -- actually its first top-level window -- which is usually special-cased in the app's message pump). But the similarities pretty much end there. Windows also uses messages for a lot of internal message passing. Also, in Windows, pretty much everything is a window, and you can iterate through all the windows owned by any process you own (generalizing here in the context of security descriptors). Neither of these is the case on OS X. You have no access to another application's internal structures whatsoever; you only have access to what the application grants you, which in most cases is merely Apple Events/AppleScript. In this sense, Apple Events are used more like COM. Long story short, you're going to need to seriously retrain yourself for how OS X is architected.

The other app does not belong to my app. If anyone could point me to some help topics on how this can be accomplished I would greatly appreciate it. Use the Accessibility API. It's designed to do exactly this. It's a C API, not Cocoa or Objective-C, but you can use it in a Cocoa application. The Accessibility API does two things: (1) it enables you to make the user controls and views in your application accessible to so-called assistive applications, and (2) it enables you to write an assistive application yourself that accesses the user controls and views of any application. The Accessibility API was created to make applications accessible to people with disabilities through assistive devices and applications. However, the Accessibility API is also wonderfully useful for doing lots of other things, such as hooking into a text chat window so that you can log the incoming messages. Apple has lots of documentation about how to make your own application's user controls and views accessible by assistive applications, but that usually is only necessary if your application has custom user controls and views. If your application uses standard Carbon or Cocoa code for its user controls and views, they are automatically accessible out of the box. But Apple offers very little documentation about how to write an assistive application, which is what you want to do. There is a reference document that describes the functions in the Accessibility API that you have to use to write an assistive application, and there are a couple of example code projects, including the UI Element Inspector example. You can download the free 30-day trial version of my PreFab UI Browser at http://prefabsoftware.com/uibrowser/, which uses the Accessibility API to read and manipulate other applications. Try it with your target application's chat window to see whether UI Browser is able to read the incoming messages. You might have to read the chat window periodically to notice new messages, but more likely your assistive application can install (or register) a notification observer that will notice every time the content of the chat window changes. You can test that in UI Browser, too. In your assistive application, you would respond to each such notification by reading the new content of the chat window and saving it to your log. -- Bill Cheeseman - [EMAIL PROTECTED] Quechee Software, Quechee, Vermont, USA www.quecheesoftware.com PreFab Software - www.prefabsoftware.com ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSMenuItem view bug with status bar menu
I believe I have found a bug with a menu item view when used in the status bar menu. Here's how to recreate the bug. Assume the app MyApp is active and has a status bar menu, and one of the menu items has a view: 1. Bring another app to the front (such as Safari), and access the MyApp status bar menu, displaying the view. 2. Bring MyApp to the front. 3. Now there is a ghost image from the view displayed when MyApp was inactive. The ghost image goes away after about 20 seconds. When I say ghost image it's just a white space void of any of the views contents. Maybe the NSMenuItem view is not meant to be used with a status bar menu? Or this is a bug? Or more importantly, does anyone know a workaround so I don't get this ghost image on the screen?

Huh. I wouldn't expect it to do that given that it's borderless.
How can I bypass this behaviour for my window?
Should I use applicationDidChangeScreenParameters and reposition
the window, or is there an option to make my window not care about
the Dock appearing?
It'd probably be easier to just override setFrame in a window

Since it'd use the entire dictionary as the value, which isn't what I want. It's kinda annoying. A value transformer seems like a good idea. I haven't looked into them yet, but I think there's a couple places where some custom ones could be handy. I'll look into that.

Thanks for the tip, I've made that function simpler (displaying a red
circle):

CGRect theRect = CGRectMake(0.5, 0.5, 1, 1);
CGContextSetRGBFillColor(theContext, 1, 0, 1, 1);

Now to get the CALayer to draw a path. Most of the documentation I've
seen
suggest to do this with a delegate function, is that correct? Here is
the
delegate function I've written (a.k.a. copied from another program):
//
- (void)drawLayer:(CALayer *)theLayer
inContext:(CGContextRef)theContext {
CGMutablePathRef thePath = CGPathCreateMutable();
CGPathMoveToPoint(thePath,NULL,15.0f,15.f);

NULL,
15.f,250.0f,
295.0f,250.0f,
295.0f,15.0f);
CGContextBeginPath(theContext);
CGContextAddPath(theContext, thePath );
CGContextSetLineWidth(theContext, 1);
CGContextSetRGBStrokeColor(theContext,0.0,0.0,1.0,1.0);
CGContextStrokePath(theContext);
}
//**
I'm just seeing the black background right now.
Again, thanks for your help and sorry I'm such a pain :)
Note that this code (by itself) leaks, the mutable path your creating is
never released (in this snippet). You actually don't need to do this anyway,
you can use CGContextMoveToPoint/CGContextAddCurveToPoint/etc instead and
not have to worry about the memory management issue that using CGPath brings
up.

Cannot Remove Observer Error
Starting earlier today, I started getting the following error in my software. 2008-04-14 17:59:41.535 WineCellar[4928:10b] Cannot remove an observer WineArrayController 0x25a450 for the key path wineType.name from Wine 0x6c55170, most likely because the value for the key wineType has changed without an appropriate KVO notification being sent. Check the KVO-compliance of the Wine class. I haven't changed anything significant (well at least I don't think I did) and I definitely have not been messing around with the WineArrayController and/or the Wine classes. I can't figure out how to track this error down -- I've tried a number of things including putting a removeObserver:forKeyPath method in the array controller so I could look at the back trace and I've also put in enter and exit debug messages in a large portion of the code. Still the error seems to come from nowhere and I am stumped as to how I might find what the root cause of the problem is. Does anyone have any suggestions as to how to track down this type of error.

Re: warning: Image scaling is not supported on Mac OS X versions prior to 10.5.
On Apr 14, 2008, at 9:09 AM, Nathan Vander Wilt wrote: This means your NIB/XIB has a deployment target not equal to 10.5.x, but you have some sort of button or other view whose Scaling setting is not None. If you go into Interface Builder, and go to your file's Info window, it will show a list of all these warnings. Either change your deployment target, or click each warning to pull up the problematic view in the inspector window and set its Scaling to None. It may be alright to ignore these warnings, I don't know. The real problem with this as I see it is that it happens with a default project with no changes. Create a new Cocoa application, open the NIB and add a Push Button/NSButton on the window. You'll get a NIB warning the OP describes immediately. Bad default settings in my opinion. In order to make the warning go away you can either set the build target for the NIB file to 10.5 or set the Scaling attribute to none for the button. Neither of this is immediately obvious to newbies like myself because you would assume things like that just work. What I've been wondering: What happens if I get a warning like this, switch my build target to 10.5 and the final application runs on a pre 10.5 system? Will it crash, will the scaling functionality just don't work or will the user get lots of error messages when starting the application?

You reply couldnt be more fanboi-ish.

You yourself said that the OS is resistant against this sort of attack in the following quotes: Well, password fields are special and are 'resistant' to key logging, but you don't have to 'hook into' any apps to log the rest. Understood - in this case, it's unsupported system hack time, since the Mac OS X world takes a different approach to security which means you have to work a bit harder. Not once did the OP ask for a 'feature', and not once was the OP criticized for asking for a way to do what he wanted. The OP asked if such a feature existed, directly implying that if it did not, then it would be a desired feature. Although you didn't criticize him, Thomas Davie did with the following reply: Someone may correct me if I'm wrong, but that sounds a lot like something that has been very very deliberately left out of any API... I want to write an app that I'd like to have hook into a text box in Safari and log your IDs, passwords, and bank account status. Several different approaches to the (very loosely defined) problem were offered by many different posters, in fact. The OP's request couldn't be more straight forward. He said he wanted to hook into a text chat window from another app so that I can log the incoming messages.

Re: is this badly written code?
I don't think there's anything wrong combining messages into a chain when you only need one variable from it. With the well-worded method names common with Cocoa it's not too hard to see what the chain is doing. Sometimes having a bunch of placeholder variables on each line can look more messy and confusing than one line of chained messages.

NSAllocateCollectable() questions
Hi all, This is a re-post since I didn't receive any response on Sunday. I've been writing a library that uses NSAllocateCollectable() quite a bit and I have a few questions about proper usage. - Copying data if I am copying to a malloc'd block, I can use memmove() regardless of whether the source is GC'd or not, right? if I am copying to a GC block allocated with NSScannedOption, I need to use objc_memmove_collectable(), right? if I am copying to a GC block allocated with nonscanned memory, I can use memmove(), right? - Zero'ing data There does not seem to be a GC-compatible bzero(). If I loop through and zero out each pointer in a scanned block, that would generate a write barrier for each pointer which is expensive. However, if I use bzero(), then libauto won't know that I've messed with the block. Will it eventually figure it out when it does an exhaustive scan? Or will it never notice that I've zero'd out the block? Thanks, Brendan ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
