Re: drawRect not being called by NSCollectionView..
Well, After some troubleshooting, it looks like the NSView that is attached to the NSCollectionViewItem object is missing its superview. Does any know how this might be possible?? I can see my Subclassed NSView being created. AwakeFromNib works, as does hitTest. The drawRect does get called, but the call to superview fails, because it is set to nil. Just for laughs, I created another NSCollectionView, with NSArrayController, etc, and manually add objects. This works, with the NSViews displaying properly. Is there a way to force NSCollectionView to reload/re-display the NSViews with a proper superview set? bob.

drawRect not being called by NSCollectionView..
Hi Everyone, I can't seem to get an NSCollectionView to render an of the NSCollectionViewItems' NSViews. I have an NSCollectionView that is bound to an NSArrayController's arrangedObjects. The NSCollectionViewItem is set up as a template, and also has its Outlet attached to an NSView. For fun I added a text label as well as an image from the Media Library, as a placeholder image on the NSView. (It helps to have something to look at!) I don't have anything bound to the NSView at all. I haven't subclassed anything either. These are the standard objects within IB. My App inserts objects into an array using the NSArrayController as needed. However, as this happens, *nothing* is rendered at all. As a test, I have subclassed the NSView, and checked the drawRect method. Nothing. I enabled selectable in my NSCollectionView and checked for a hitTest method in my view. I can blindly click inside the NSCollectionView to the approximate location of the view, and see an hitTest response. Strange! So I know that my NSView is being recognized by my NSCollectionView, as hitTest is being called. But drawRect isn't happening. Can anyone hazard a guess at what I am doing wrong? Some notes.. This interface is to drive a network device. As such, the UI doesn't actually populate with anything until it is discovered over the network. As a matter of fact, the array that the NSArrayController uses doesn't even exit during the "awakeFromNib" process. The actual array is created as soon as the device comes online, and is attached using a binding. Perhaps I need to send some sort of message to the NSCollectionView after the new array is bound?

Quandary : NSAppleScript ties up main thread
I currently run AppleScripts using -[NSAppleScript executeAndReturnError:]. Sometimes, but not often, one of them takes 5-10 seconds to execute, and when this happens I'd like to display a small window showing indeterminate progress. However, any invocation to NSAppleScript must occur on the main thread, so the main thread is going to be blocked while it is running. I can run my 1-second timer on a secondary thread, but to display a window or even un-hide a progress bar in an existing window, I need the main thread. (Correct?) Thus, this ain't going to work. NSAppleScript does not seem to have any asychronous/callback methods for executing scripts. The only solution I can think of is to not use it. Instead, maybe launch the script as an application, and return the result by writing it to a temp file which I'm observing with a kqueue, or some other form of interprocess communication. I don't think AppleScripts can talk to Mach ports. Any suggestions to make this simple little enhancement less painful?

Re: Give a menu keyboard focus – in code
An issue I discovered recently: If your NSStatusItem uses a menu it gets AXPress for free but if it uses a custom view, the view needs to implement all the necessary accessibility pieces required for AXPress itself. Granted its accessibility is rather lacking if keyboard navigation doesn't work, but at least it'll be there for other cases.

Thank you, Andy.
After thinking about what Kevin Callahan has done with Accessorizer, and the
suggestion by Graham and Seth, I have an answer that's even better than what I
was looking for.
Like Kevin's Accessorizer, which is a utility for Xcode, my app is a
bookmarking utility which, among other things, grabs sites from web browsers.
Users want it to be accessible via a global keyboard shortcut while other apps
are active. My original idea was to make this shortcut activate my app's
Status Item or Dock Menu. But now I realize that, thanks to -[NSMenu
popUpMenuPositioningItem:atLocation:inView:] which was introduced in 10.6, I
don't need the damned Status Item or Dock Menu. This is great, because the
same anti-mouse keyboard-aholic power users who want the global keyboard
shortcuts are generally the same users that hate Status Items and hate the Dock.
So all I do is InstallApplicationEventHandler(), and RegisterEventHotKey() with
the user's preferred keyboard shortcut. My handler invokes this 3-line method
which is implemented in the NSMenu subclass which I use for my Status Item and
Dock Menu…
- (void)popUpAnywhereMenu {
NSPoint mouseLocation = [NSEvent mouseLocation] ;
[self popUpMenuPositioningItem:[[self itemArray] objectAtIndex:0]
atLocation:mouseLocation
inView:nil] ;
}
Hit the keyboard shortcut while in any web browser, and Poof! My app's menu
appears, with keyboard focus, at the current mouse location on the screen.
I'll leave my Status Item Dock Menu as a preference option for the mouse fans.
But I'm also keeping my Bug 10122120 open, because it's stupid that the F8
shortcut can't access non-Apple Status Items. We can't all be as smart (or
hacky as Charles suspects) as the bjango guys are.

Keeping grayscale image grayscale
I'm working with 16-bit grayscale images, and for the most part I'm just manipulating bits within NSBitmapImageRep objects. However for convenience it would be nice to do some stuff with NSImages, particularly when rescaling and suchlike. The problem is that whenever I draw into such an NSImage it gets converted to 3x8 bit RGB. Is there a simple way I can force things to stay grayscale, or am I fighting a losing battle here. The code snippet I have looks like this: NSImage *srcImage = [[NSImage alloc] initWithContentsOfFile:thePath]; NSImage *destImage = [srcImage copy]; // Attempt to "encourage" same 16-bit grayscale format as source [destImage setSize:destSize]; // Shrink dest image // Draw image into a new image at reduced size // This causes the result to be saved as a 3x8 bit RGB TIFF (which is not what I want!) [destImage lockFocus]; [srcImage drawInRect:destRect fromRect:srcRect operation:NSCompositeCopy fraction:1.0]; [destImage unlockFocus]; [[destImage TIFFRepresentation] writeToFile:destFile atomically:NO]; Does anyone have any suggestions?

That’s sort of odd (that string in Geneva 10 displays correctly in TextEdit.) Are you drawing directly to a view or into an image? My advice would be “don’t use Geneva”, which has been solid advice since 1991. Geneva was created as a bitmap font on the earliest version of Mac OS back in 1984, and had some truly screwy nonlinear metrics. A TrueType version was added in 1991 as an extrapolation from the original bitmaps, but it was kind of a hack. It’s only kept around for backward compatibility with old Carbon apps. For any real purpose you should use Helvetica instead. —Jens___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

When Wil Shipley wrote his blog article in April 2006 the API was at the 10.4 Tiger level. Since then NSTreeController has had one method revised and six new methods have been added in the 10.5 Leopard API. The 10.5 release notes also talk about the improvements made to this class. So Apple has been working on the class. Perhaps the bindings also work better. --Richard ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

(Readers: He means you could drag an entity into a window in IB from a data model, and an assistant would build a UI for that entity automatically. There was also a pseudo-object in the library that would allow you to do the same thing.) Nobody who knows Apple's plans for Xcode is allowed to talk about them. Somebody else, on the xcode-users list (which is a better place for questions about Xcode), was caught by the loss of that very feature today. If you want the feature to return, go to bugreport.apple.com, file a feature request, and state a concrete case for why you need it. — F ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSTreeController with bindings and core data - still an issue?
Hi, I'm looking to implement a simple iTunes/Mail like source list in an app, and have been rummaging through the internets for some decent tutorials and sample code. I found some, but they are all a bit outdated. Basically, I want to combine my Core Data model with an NSOutlineView and NSTreeController all connected through bindings. However, I've also come accross some websites (eg http://blog.wilshipley.com/2006/04/pimp-my-code-part-10-whining-about.html or http://www.cocoadev.com/index.pl?NSTreeController) that state that NSTreeController, Core Data and bindings are not really working well together, and I should use the datasource approach. Is this still the case, or has NSTreeController improved over the years and can it be used with bindings without any problems? - Koen. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Scripting Bridge Finder
Hi, with Scripting Bridge Finder, I am trying to change the folder window size and the icon position of the files therein. I got 2 troubles. 1) If the folder window is closed, I can't resize it. 2) After I change the position of the icon, I have to close the folder then reopen it, in order to see the change. Any idea on how to fix that? Regards -- Leonardo ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

However, you are correct. I just installed iStat Menus from bjango.com and, indeed, its Status Items *are* accessible via F8. Furthermore, instead of being appended to the left, they take priority over all the other non-Apple Status Items. The right half of my menu bar looks like this: | Other Non-Apple Items | iStat Menu Items | Apple Items Apparently, bjango has figured out a trick that no one else has. I wonder if it's "legal"? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Sandboxing + NSSavePanel's accessoryView
Hello, I am trying to enable sandboxing in my app, and I am dealing with a very strange behavior. I am not sure if this is a bug of Lion/Sandboxing or I have missed something in documentation. In save panel I am using a custom accessoryView which is set in "- (BOOL)prepareSavePanel:(NSSavePanel *)savePanel". I am setting setting accessory view to the real one only if savePanel's "- (BOOL)isExpanded" returns YES. Otherwise I am setting it to nil. To handle save panel's expansion I am using "- (void)panel:(id)sender willExpand:(BOOL)expanding" from NSOpenSavePanelDelegate. If expanding == YES, I am setting the real accessory view, and nil if expanding==NO. That worked very well on Snow Leopard. It even works well on Lion without sandboxing. But if sandboxing is enabled, it does not work. When save panel is displayed and I am trying to expand it, expands and collapses back. It is impossible to expand it. Log has showed, that I am getting - (void)panel:(id)sender willExpand:(BOOL)expanding with expanding==YES and the second one with expanding==NO. At the moment I have no clue what is going on. Any thoughts about this behavior would be very appreciate.

Accessorizer's "Action Menu" is a status item that provides the exact UI Jerry is talking about, and I think it is brilliant. Not only can you use arrow keys to navigate the menu once you've popped it up, but in Accessorizer there are a couple dozen menu items, all with keyboard shortcuts, and with this UI: * You don't have to memorize all those shortcuts (although eventually you will remember the ones you use most frequently). All you have to remember is Accessorizer's one shortcut to pop up the menu, and the menu items within the menu display their shortcuts. * It doesn't matter if the shortcuts conflict with shortcuts in any other application, because the status item's menu has focus when you pop it up. Compare this with keyboard shortcuts for Services, where a conflict can be a problem, especially if you have lots of them. Kevin Callahan came up with the Action Menu precisely because the menus in Xcode 4 use so many keyboard shortcuts, including many he had been using for the Services provided by Accessorizer. * The keyboard shortcuts can be plain characters without modifiers, which makes them easy to type and remember. This wouldn't be possible if you had to worry that a text field might have focus, because the characters would get entered into the text field. Gesturally and conceptually what Accessorizer does, and Jerry wants to do, is similar to Command-Tab: a globally-available special keystroke enters a mode that allows you to select from a bunch of items either with the mouse or with arrow keys. (One difference is that with Command-Tab you have to keep the Command key down while you navigate.) There are third-party apps like Alfred that are even more similar in concept. There are tradeoffs for both the user and the developer between the Action Menu approach and the Alfred approach. For some reason I find Accessorizer's approach feels very natural and appropriate for what it does. I don't know how Kevin implements it, but I suspect it's by using a custom view in the status item as has been suggested. --Andy ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Give a menu keyboard focus – in code
I haven't been following this thread closely, so I may be talking about the wrong thing here, but I just noticed I can cycle through the status items, and some of them (e.g. istat menus and apple items) are selectable with ctrl-f8 then arrow keys, and some not (e.g. dropbox). So it seems like it's possible, in principle. Don't know if that helps.
