Timeout after application:openFile: stalling applescript
My application implements the NSApplicationDelegate method
-application:openFile: in its app delegate. There seems to be a problem new
to OS 10.8 where after receiving the apple event to open a file, five
seconds pass before some kind of internal timeout is hit, a response is
sent to the apple event, and the calling app (e.g., applescript editor)
proceeds.
In detail, here's what I see. After application:openFile: returns YES, I
can see that -[NSAppleEventManager suspendCurrentAppleEvent] is called:
#0 0x7fff8f07b5ed in -[NSAppleEventManager *suspendCurrentAppleEvent*]

#1 0x7fff8f90458e in -[NSApplication(NSAppleEventHandling)

After five seconds, -[NSAppleEventManager resumeWithSuspensionID:] is
called:

#1 0x7fff8f90585f in __block_global_1 ()

Evidently, some kind of timeout was reached since resumeWithSuspensionID:
is called from a timer and it is always very close to 5 second between my
application:openFile: method returning and resumeWithSuspensionID: being
called.
After this, things proceed normally: whatever applescript invoked "open
file ..." continues at the next statement. There don't appear to be any
errors--it just times out waiting for something.
I turned on AEDebugSends and AEDebugReceives. Here's what I see up to the
timeout:

NSComboBox with NSNumberFormatter DataSource works but not Content binding
Here's a little mystery that maybe someone can help me with… I have an NSComboBox for numbers (and hence with an NSNumberFormatter attached to its text field) for which I'd like to populate some items in the drop down list. I understand that I must present NSDecimalNumber objects for list content and I'd prefer to use bindings for this, so I create a simple NSArray of NSDecimalNumber values and provide this as the Content binding. I get a drop down list with no visible values. If I give up and use a DataSource, I can instantiate NSDecimalNumbers in the -comboBox:objectValueForItemAtIndex: method and everything works peachy. Now, I don't know what this means exactly, but I thought I'd implement a value transformer in the Content binding, just to take a look at the values flying by and maybe assert values of NSDecimalValue type. What I find is the transformer is provided with the _whole_ array to transform, rather than individual value elements as I'd expect. It's hard not to conclude that NSComboBox with an NSNumberFormatter attached is somehow broken for binding, but I'd certainly like to be put right on that score. In the meantime, I have a workaround in the way of a DataSource. But I'm sad. I like binding things. -- Luke ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Mac cursor hotspot is not at the tip of the cursor
Hi all! Just figured out that for some reason on Mac OS X default cursor (black with white border) has it's hotspot not on the tip of the white border, but inside - on the tip of the black arrow inside. Assuming this, using default cursors with small custom graphics elements is weird - you think do click, but actually you don't. Enlarging cursor in Universal Access makes issue even more weird - the cursor is enormously big, but still has hotspot on the tip of the black arrow inside the white border. Is there any way to make using default cursor as customer expects and make it's hotspot at the tip of the white border, not inside it, of the default cursor arrow?

Targeting actions/methods on selected object in NSObjectController
I'm not clear on the options for targeting actions on a selected object in bound UI. I have some list of objects (like a master list), out of which selection allows a single object to show details in UI below. So, this is a pretty standard Master-Detail set up. I have an NSObjectController managing the selected object and a lot of UI binds to properties of this of course in order to display and edit things. Now one of the properties of this selected object is another list (array) of things, so these area displayed in a table with little "+" and "-" buttons in the popular style. I need to get the "+" button to fire an action on the selected object managed by the NSObjectController. It would be perhaps regular to have an action defined on the class of these selectable objects such as: - (IBAction)addListItem:(id)sender However, I can't see how to target the object inside this NSObjectController in the normal way in xcode (4.4.1 btw). NSObjectController supports a small number of its own actions, and even if it were to somehow pass actions down to the contained object, there's no way I can see to define custom actions on most objects in xcode. Obviously, I could target some other higher-level controller (like a window controller, app controller etc.) that could then have an outlet for the NSObjectController in order to get at its selected object, but that seems like going the long way round and it would create some 'noise' in the form of an extra outlet and actions at that level. What does seem to work (and is the approach I'm taking now) is the Target binding on the "+" button, bound to the NSObjectController's selection. This works fine, except that I can't easily target action methods, because I can't see how to generate the button's "self" as the Argument binding easily (not without adding another unwanted outlet on a controller just to acquire the button object). So, I currently just target a zero argument method: - (void)addListItem So, in a nutshell, what I'm asking is whether there's a nice way to connect to an action method within an NSObjectController from my button action. Perhaps the Target binding _is_ the only way this is supposed to work directly in this sort of scenario? -- Luke ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Converting NSImage with multiple image representations (HiDPI+LowDPI) into grayscale NSImage
Hi, I have been running into a problem wherein I need to grayscale all the NSImageRep objects within a NSImage (i.e. say NSImage contains two representations for testimg.png and test...@2x.png). CGImageRef which has a one-to-one correspondence with one image representation. With CGImageRef, the conversion to grayscale is straight-forward. I can pick out NSImageRep objects of NSImage and then use [NSImageRep CGImageForProposedRect:context:hints:] method to extract CGImageRef. I can do grayscale conversion on each of these CGImageRefs, however I cannot put these back into a single NSImage. Is there a way to do this without converting to CGImageRef? How do we handle multiple representations when applying grayscale?

Ever since the beginning of [Mac] time, the hotspot is at the tip of the black arrow -- the black arrow *is* the arrow. The white border around it is there just to make the cursor visible when it's over a dark background. If a dark background is general in your app, you could provide your own cursor image, and put the hotspot wherever you want, but whenever the cursor changes back to the standard arrow (e.g. outside of your windows) the hotspot is going to be the tip of the [black] arrow as it has always been. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

This is a traditional (irritating) message that could be better handled in Objective-C. You're sending a message to do something to an object that doesn't have that method implemented in it.

Re: maintaining alpha value for intersecting lines?
It is the expected behavior, since the stacking of two partially transparent objects leads to a less transparent set. So I don't know what you want is possible. Are your lines straight ? If so, maybe you could try to draw one of them in two segments, to avoid the intersection (beware of the anti-aliasing). - Jean On 13 sept. 2012, at 14:40, Koen van der Drift wrote: > When I draw two lines using NSBezierPaths, both of which have an alpha > value of let's say 0.5, the alpha value appears to be higher at the > intersection (the color becomes more opaque).

Re: maintaining alpha value for intersecting lines?
It is higher. That's what happens when the lines intersect. The effect is additive. Unless you have a mode setting where the compositing replaces what's below it. The alpha of the top curve doesn't change at the intersection point. What you're doing is putting one alpha-ed pixel on top of another, and the alpha on the top one lets the one below it show through based on the alpha value of the top pixel.

I was able to reproduce and fix this problem that went away a few weeks ago.

Indeed, that is what was happening. I was sending setDelegate:nil during -windowWillClose:, but the message was not being delivered because when I replaced RBSplitView with NSSplitView to make the project buildable in Xcode 4, I neglected to reconnect the outlet from the window controller to the new NSSplitView.

Re: maintaining alpha value for intersecting lines?
I'm afraid it won't work. That's the principle of transparency: you can see what's below, tinted by the color of what's on top. What are you trying to do ? Maybe there's an other way around.

Are the lines the same color?

Re: maintaining alpha value for intersecting lines?
More specifically, CGContextBeginTransparencyLayer() and CGContextEndTransparencyLayer() will do what you need, in case you can't use a single bezier path. You set the global alpha to the transparency you want, start the transparency layer, draw *without the alpha*, end the transparency layer. Marcel typed into mail - CGContextSetAlpha( context , 0.5 ); CGContextBeginTransparencyLayer( context, nil ); [[NSColor colorWithCalibratedRed: 0.1 green: 0.1 blue: 0.1 alpha:1.0] setStroke]; [bezierPath1 stroke]; [bezierPath2 stroke]; CGContextEndTransparencyLayer( context ); typed into mail - On Sep 13, 2012, at 18:30 , Koen van der Drift wrote: > On Thu, Sep 13, 2012 at 12:00 PM, Andy Lee wrote: >> Are the lines the same color?

Hints for supporting dragging a file onto the dock icon, then onto a row in menu presented at that point?
I'm pretty new to OS X development and just looking for hints about how to do something like this... I saw an app called Dragster that allows you to drag a file over the dock icon for the app, at which point a menu of rows opens up form the app icon, and you can continue to drag the file over a particular row. I'd like to emulate that notion of dragging a file over the dock icon, then over a row in a menu presented from the icon. So far I've played with: 1. Using the openFile: and openFiles: NSApplication delegates to let me handle dragging a file over the icon and handling that. 2. Modifying the dock menu to add items and separators to the dock menu (at least simple cases). But what I notice here is that this menu if presented on a two-fingered click of the doc icon, not presented when I drag the file over the dock icon. How do I get the or a menu to show when I drag the file onto the icon? Then, once I get a menu showing, how do I get to the point where I can drag the file onto a row in the menu? I'm perfectly fine with pointers for things and areas to look at relative to this... Thanks in advance!

Sandboxing not so bad
Sandboxing is not as restrictive than I though it would be. For example, the documentation for the entitlement: com.apple.security.files.user-selected.read-write says this entitlement provides: "Read/write access to files the user has selected using an Open or Save dialog" . I was reading more into that than I should have. If you use the Open dialog to access a file, then you can read and write to the file. You don't have to use the Save dialog to write to the file. And that file can be anywhere on the file system (except for system files I guess). And yes the app is really sandboxed. If no entitlements are enabled I can't do anything (except read and write to recent documents in the Open Recent menu). So with just that entitlement and a Printing Entitlement I can do just about everything I could previously do before Sandboxing. The only thing I can't do is write comments to the Finder GetInfo window -- because that uses Applescript. But I can live without that. So unless I'm missing something, sandboxing is a piece of cake.

Another sandboxing snafu
Grrr... and here's exactly the sort of stupid thing that I was referring to a
moment ago in another thread...
I'm attempting to show an NSOpenPanel as a sheet, app is sandboxed. This has
always worked perfectly fine:
NSOpenPanel*op = [NSOpenPanel openPanel];
[op setAllowsMultipleSelection:NO];
[op setCanChooseDirectories:NO];
[op setAllowedFileTypes:[NSImage imageFileTypes]];
void (^completionHandler)(NSInteger result) = ^(NSInteger result)
{
if( result == NSFileHandlingPanelOKButton )
{
// do stuff with URL from panel (omitted)
}
};
[op beginSheetModalForWindow:[self windowForSheet]
completionHandler:completionHandler];
But now when this code runs, the following is logged:
14/09/12 9:02:18.578 AM WindowServer[108]: CGXSetWindowShape: Operation on a

Anyone got this simple use of NSOpenPanel to work with sandboxing?

Combining paths into a single NSBezierPath means those paths are treated as a single object for a drawing operation, and intersections are rendered accordingly. However, this behaviour doesn't come at no cost - the code has to find those intersections and deal with them by ensuring that the same pixels are not rendered twice.

Re: kABHomeLabel … and companions
I understand that ABAddressBook methods are concerned with ABPerson and ABGroup
entities, subclasses of ABRecord.
However, the ABMultiValue collections are less intuitive. Among these are
stored the (potentially) multiple instances of addresses, phone numbers and
email addresses. For each instance of user supplied data, a multiValue object
can store - in properties keyed with kABXxxx keys - arbitrary labels: home,
work, iPhone, mobile, etc. The documentation leaves much to be desired, but
in particular, I cannot glean how to retrieve a user-supplied string from a
given multiValue object.
Some code:
Given some address, stored in an ABMultiValue object, such that:
- (void) unwrapMV:(ABMultiValue*)mv atIndex:(int)index {
NSString * _uuid = [mv identifierAtIndex:index];
NSString * _label = [mv labelForIdentifier:[mv
identifierAtIndex:index]];
NSDictionary * _dict = [mv valueAtIndex:index];
// am I the identified primary entry?
BOOL_primary= ([mv primaryIdentifier] == self.uuid)?
YES: NO;
NSLog( @"%@", _label) ;
}
produces _$!!$_,
or one of the other variants of the actual value of the key, not the value it
refers to.
Clearly I am failing to understand where these strings are being stored.

Or maybe synthesizing accessors should not baked into language, but rather part of (user-extensible) libraries.

Re: Hints for supporting dragging a file onto the dock icon, then onto a row in menu presented at that point?

I think they are using some dark-gray magic to do that kind of thing; see below. It’s not at all straightforward. This isn’t something that sounds reasonable for a newbie programming task. > 1.

Dragster definitely isn’t using a normal dock menu — this must be a custom window that they open and do mouse-tracking in. I don’t know how they detect that the mouse is over the dock tile, or even how they figure out the on-screen coordinates of the tile. There isn’t any straightforward way to do either. (NSDockTile only lets you customize the appearance of the tile; it doesn’t support any special event handling.) My suspicion is that they are using a private API that lets the app run a real live NSView in the dock tile. With that it would be pretty easy to build that sort of UI. I know that this API has existed for a long time, but I don’t know the details (and talking about private APIs on this list is not allowed.) —Jens ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
