Simple NSDatePicker query

[jonat...@mugginsoft.com]

Is it correct that a textual NSDatePicker can only display dates in short 
format ( dd/mm/ )?
Attaching a date formatter and setting say a long date format seems to have no 
effect.

Re: Why is an IKImageBrowser method not firing?

[Reinhard Segeler]

1. Is the method really called? Log it...
2. Do you update the data source?
3. Is the data source reloaded after updating?

Check the project "DatePicker" in the documentation. It should allow you,

The textual pickers in the example project display as dd/mm/. So no 
solution that I can see.

Getting the ImageBackground example to work on Mavericks

[Sebastien Boisvert]

I pulled out the older ImageBackground example (which shows a custom background 
image in a NSTableView/NSOutlineView) and am trying to make it work under 
Mavericks.
 
For the most part, it's working fine by explicitly disabling support for 
responsive scrolling. The only glitch that remains is expanding/collapsing 
items in the outline view - there's a visibile 'flash' that happens when the 
rows get added or removed (expand/collapse animations have also been disalbed 
for this), where the background it redrawn.
 
This worked fine under Lion/Mountain Lion, it's only under Mavericks that the 
glitch happens. I'm wondering if there's a way to avoid this as we use a 
similar technique in a view in our application.
 
P.S. for those unfamiliar with the example - it uses cell-based views.

Thanks for any insights.

Re: RSA and libcrypto

[James Moore]

I might as well post my gist for building openssl and lib crypto fat binaries 
in case someone wants a “build it once” solution

https://gist.github.com/foozmeat/5154962

It supports:

Mac: i386 and x86_64
iOS: armv7, armv7s, and i386. It will add arm64 and x86_64 support for iOS 7 
SDK (the default).

I was intrigued so I had to do a test app.
This is doable.
Not pretty, but very doable and without any subclassing.

Basically, you can create this with NSMenuDelegate, swapping menus for 
NSPopUpButton using setMenu: and a little recursion to force the issue of 
selection (or state in NSMenuItem terms) and lastly a little 
NSNotificationCenter.

You’ll need a reference (property or ivar) to your NSPopUpButton, to an NSMenu 
that will only display the selection, and to the NSMenu that will be your 
flyout enabled menu (a menu with submenus). You will also need an NSMenuItem 
property or ivar that will both help you know what should be selected when you 
swap menus and what should be deselected when you next display your flyout menu.

Here’s a simple app delegate interface and implementation to show you.


@interface MyAppDelegate : NSObject 

@property (assign) IBOutlet NSWindow *window;
@property (weak) IBOutlet NSPopUpButton *popUpButton;
@property (weak) IBOutlet NSMenu *selectionMenu;
@property (weak) IBOutlet NSMenu *flyOutMenu;
@property NSMenuItem *currentSelectedMenuItem;
@end


@implementation MyAppDelegate

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
// Insert code here to initialize your application
[_popUpButton setMenu:_selectionMenu];
[self 
addSelector:@selector(selectSenderAndMakeSelectionMenuShowSender:) 
toAllMenuItemsInArray:_flyOutMenu.itemArray];
[[NSNotificationCenter defaultCenter] addObserver:self 
selector:@selector(handleNSPopUpButtonWillPopUpNotification:) 
name:NSPopUpButtonWillPopUpNotification object:_popUpButton];
}

- (void)addSelector:(SEL)aSelector toAllMenuItemsInArray:(NSArray *)items {
for (NSMenuItem *aMenuItem in items) {
if (aMenuItem.hasSubmenu) {
[self addSelector:aSelector 
toAllMenuItemsInArray:aMenuItem.submenu.itemArray];
} else {
[aMenuItem setAction:aSelector];
}
}

}
- (IBAction)selectSenderAndMakeSelectionMenuShowSender:(id)sender {
NSMenuItem *selectedItem = (NSMenuItem *)sender;
if (_currentSelectedMenuItem != nil) {
if (![_currentSelectedMenuItem isEqualTo:selectedItem]) {
[_currentSelectedMenuItem setState:NSOffState];
}
}

[selectedItem setState:NSOnState];
[self setCurrentSelectedMenuItem:selectedItem];

[_selectionMenu removeAllItems];
[_selectionMenu addItem:selectedItem.copy];
}

- (IBAction)popUpButtonAction:(id)sender {
NSLog(@"[%@ %@: %@]", self, NSStringFromSelector(_cmd), sender);
NSMenuItem *selectedMenuItem = [_popUpButton selectedItem];
NSLog(@" selectedMenuItem=%@", selectedMenuItem);
}

- (void)menuWillOpen:(NSMenu *)menu {
NSLog(@"%@", NSStringFromSelector(_cmd));

if ([menu isEqualTo:_selectionMenu]) {
NSLog(@" %@", menu);
} else if ([menu isEqualTo:_flyOutMenu]) {
NSLog(@" %@", menu);
}
}

- (void)menuDidClose:(NSMenu *)menu {

[_popUpButton setMenu:_selectionMenu];
}

- (void)handleNSPopUpButtonWillPopUpNotification:(NSNotification 
*)aNotification {
[_popUpButton setMenu:_flyOutMenu];

Re: NSNumber : method to return pointer to represented value

[Mike Kluev]

> I require an pointer to the value represented by an NSNumber.
> ...
> I am using NSNumber instances in collections as keys.

i may not fully understand your question, but can you not just use
NSValue valueWithPointer as your collection keys?
or, if a number at all, the number matching the pointer representation:
[NSNumber numberWithLong:*(ptrdiff_t*)&pointer]
or a string in a similar manner: [NSString stringWithFormat:@"%p", pointer];

in my experience resorting to tricks of objc_getAssociatedObject is
asking for trouble (e.g. the associated object is not released with
zombies).

How to create a Tags selection field in a dialog

[Ben Staveley-Taylor]

I’m considering making use of the Finder Tags functionality in Mavericks but 
the APIs seem a little sparse.

I want to create a UI with a field like the Tags: field on the Save As dialog 
so I can ask the user “Which tags do you want to use on files of this purpose?” 
This would not be at the point of saving the file, but in an application 
preference. (My application never opens or saves files; it is a file manager 
that just moves them around, so I don’t have a Save dialog.)

How can I ask the user to specify a tag, or set of tags, to use?

Ideally I would like to create new Tag string of my own (e.g. “MyApp To Do 
List”) but I can’t see any tag management API in NSWorkspace. Is it possible to 
do that, or even to enumerate what Tags are available and what colors they use?

Thanks

— Ben

Finder Tags API

[Ben Staveley-Taylor]

I’m trying to understand the Finder Tags APIs in Mavericks.

I would like to set a custom Finder Tag on a number of files, ensure it appears 
in the Finder sidebar tag set, and assign it a color so the user can gather the 
files easily in the Finder. My application is a file manager and moves files 
around, but never actually opens and saves them so the user cannot explicitly 
assign Tags in a save dialog.

Let’s say I want to use “My Tag” as the tag string. I can assign a tag like 
this:

NSDictionary *dictTags = [item resourceValuesForKeys:[NSArray 
arrayWithObject:NSURLTagNamesKey] error:&error];
NSArray *arrPreviousTags = [dictTags valueForKey:NSURLTagNamesKey];
NSArray *arrNewTags = [arrPreviousTags arrayByAddingObject:@"My Tag"];
[item setResourceValue:arrNewTags forKey:NSURLTagNamesKey error:&error];

then “My Tag” shows in the Finder tags list, but with no color. I can’t seem to 
find much by way of a Tags API other than the NSURL NSURLTagNamesKey resources.

How can I assign a color to the tag “My Tag”?

I’d even settle for always using the standard Red tag, for example, but I would 
need to check that it exists in case the user has changed the default Tag set. 
And it might have a different name in other localizations. Can I enumerate all 
the Finder Tags that are available? The NSWorkspace labels don’t seem to be the 
same thing:

   NSArray *possibleTags = [[NSWorkspace sharedWorkspace] fileLabels];

always returns: None, Gray, Green, Purple, Blue, Yellow, Red, Orange, i.e. not 
my custom tag, nor even the standard “Important”, “Home” or “Work”.

Thanks,

— Ben.

(PS: I made a similar post a week or so ago but I don’t think it ever got to 
the list. Apologies if anyone gets this twice.)

Saving while opening with NSDocument

[Colas B]

Hi (this is my first email on the Apple mailing list) ;-)

I would like to perform `saveDocument:` in the process of opening a document (I 
call this method in `- (id)initWithContentsOfURL:ofType:error:`.

It does not work because of a deadlock.

I would like to know if you have any idea about that.

PS: I also tried to override `(id)makeDocumentWithContentsOfURL:ofType:error:` 
and `- (void)openDocumentWithContentsOfURL:display:completionHandler:` (for 
this purpose, I subclass NSDocumentController. I have tried to call 
`saveDocument:` in "windowDidLoad". All lead to the same deadlock.

PPS: Why do I want to do that? When a document is opened, sometimes some 
corrupted data needs to be fixed. I do it, but I want to save these fixes. So 
that the user won't remark anything.

PPS: My document handles "additionalData" (file wrapper), but this should not 
change anything.

Thanks
Colas

menuNeedsUpdate for key equivalents?

[Jim Prouty]

Our app allows the user to write programs and to create custom menus and menu 
items, including setting key equivalents.

Because the key equivalents are under user control and because we re-use some 
for multiple purposes, menu items' key equivalents change a lot.

We need to get a chance to update/modify the menus and key equivalents *before* 
Cocoa starts looking for menu items that match the key equivalent.

At that time we need the ability to add/remove menus and menu items, set key 
equivalents, and enable/disable menu items.

menuNeedsUpdate: is an NSMenuDelegate Procotol that allows us to do exactly 
that when the user clicks in the menubar.


https://developer.apple.com/library/mac/documentation/Cocoa/Reference/NSMenuDelegate_Protocol/Reference/Reference.html

We'd love to have menuNeedsUpdate: be called before Cocoa starts calling 
menuHasKeyEquivalent:forEvent:target:action:.

menuDidOpen: is too late, according to the docs:

"Special Considerations: Don’t modify the structure of the menu or the 
menu items during this method."

Is there any way with OS X 10.6 and later to get this kind of advanced 
opportunity to modify menus and items for key presses?

Maybe some other class's delegate?

(Some our customers have 20 years worth of documents/programs which make rely 
on this feature, which Carbon's MenuSelect provides to this day.
That is, MenuSelect allows us to rebuild the menus for both key events and menu 
bar events.)
