Re: Status bar item icon is always black

[Georg Seifert via Cocoa-dev]

Why do you put the images in an asset catalog? I use PDFs a lot for icons, (in 
my case mostly as Template images). But I just drag them into a groups in Xcode 
and they are copied into the Resource folder. Then you can load them with 
-[NSBundle imageForResource:]. If you have @2x version, they are loaded 
automatically (if they are not combined on build time.
To control if it is a Template, add that string to the file name, or in your 
case, don't add it.
Sometimes I "preload" images early and then do [image setName:@"imageName"]. 
That way you can get it by calling [NSImage imageNamed:@"imageName"] (not sure 
if that is really needed).

Asset catalogs are useful if you need more functionality. e.g. if you actually 
need a .icns files. Or if you have different versions for light and dark mode.

Re: Localization under Catalina

[Georg Seifert via Cocoa-dev]

The apps work with either, nibs and Base localisation. The main advantage is 
that it provides an app for the translators and a file format that contains all 
the keys. So you don’t need to send all those .strings files (if you have a 
couple sub projects that gets really messy (I have 40 or 50 plugins and 
frameworks). You send your translators a .loc file, they translate it and send 
the file back. You import it in the Manager app and it will update all your 
.nibs and .strings. Adding a new language to my app took one hour or so on my 
part. Importing new translations takes 1 minute. I wouldn’t be able to have any 
localisation without those tools.

I use the http://www.loc-suite.org for all my localisations. The original

It is very good at keeping existing translations.

Re: Finding memory leaks

You need to check the backtrace where the leaking object was created. Sometimes 
it points to a line that has nothing to do with the leak, it is just triggering 
it.

Re: Concurrent loading of images ?

The last time I used layers to draw images it made a HUGE difference if the 
image was pixel perfect matching the size of the layer. If the image needed 
scaling, it was quite slow (I had really tiny images, but a lot of them).

Check if there are autosaved documents

[Georg Seifert via Cocoa-dev]

Hi,

my app shows a welcome screen (that offers to open recent documents or to make 
a new). I like to not show it, when there are autosaved documents that open 
automatically. 

Now I open that window in applicationDidFinishLaunching: but that is called 
before the documents start to load. 

Is there a method/callback that is called when all loading is done (including 
the loading of documents). 

Or, is there a way to check if there are autosaved docs (before they are 
loaded)?

Thanks

Re: Catalina scroll view issues

[Georg Seifert via Cocoa-dev]

I read most of the discussion but maybe missed some parts so it might repeat 
something or miss the point altogether. 

How big is your view. I had a lot problems with a big view and layer backing. 
It will use tiled layers as a layer can only be a few thousand pixels tall. 
And when you do any checking for the dirty rect you will miss drawing in some 
of the tiles...

 The way it looks it seems very much related to the scrolling mechanism, 
 the pre-rendered portion is not rendered but for some reason the scrolling 
 mechanism thinks that it is. I really don't see how a core-graphic issue, 
 and certainly not a misuse on my part could cause a view to be partially 
 rendered.
 BTW, do you think this type of issue is appropriate for a DTS incident?

 Thanks. I saw that but I recall that in the past you used to have app-kit 
 specific release notes which were usually more detailed.

 When I started developing this app (2002), there was no choice other then 
 CG since core text didn't exist and the other technologies didn't support 
 Hebrew and RTL well, if at all. So I wrote my own text engine and this was 
 very good for me commercially as my app was the the first and only 
 word-processor to support Hebrew (and later Arabic) properly on Max OS X. 
 I had a similar experience with OpenType which was not initially supported 
 and that also gave me an edge. As time passed Apple did improve the RTL 
 support and was offering more APIs so theoretically I could have rewritten 
 my code to use the new APIs but in reality I actually did the opposite and 
 relied less on Apple's APIs (for example, parsing 'cmap' tables) because 
 there were always bugs and even regressions which could render my app 
 unusable upon an OS upgrade. Beyond the bugs, I think my RTL is better, or 
 at least as far as I'm concerned as a native Hebrew speaker and having 
 such low-level control over something that is core to my app is essential 
 IMO.

printing black

[Georg Seifert]

Hi

I have a app that can print black shapes (using normal cocoa view based 
printing). A lot users complain that the printouts are not really black (the 
printouts are rastered, so the color sync tries to simulate a CMJK black but 
even thou that it is black already). 

We played around with the pdf made form the print dialog. Printing that from 
Adobe Acrobat produces the same results. But Acrobat has an option to convert 
the PDF to optimise it for Digital printing. It attaches a genericGrayscale 
profile to the PDF. 

Does any have a hint what to do? 

Thanks
Georg

Re: Crash in terminate: on Mavericks

[Georg Seifert]

Your symbol settings are wrong. Make sure you use a target that has any. 

DEBUG_INFORMATION_FORMAT = dwarf
COPY_PHASE_STRIP = NO
STRIP_INSTALLED_PRODUCT = NO

Then you should at least see where it happens.

Xcode 10 and disable layer backed windows in Mojave

[Georg Seifert]

When I build my app with Xcode 10, Mojave uses the new layer backed windows. My 
view drawing is (not yet) able to dealt with layer backed views. 

So is there a way to disable the new window system? The only way I fond is not 
to link against the 10.14 SDK. But that is the SDK Xcode 10 is using even in 
10.13. 

Is there a way to link against the 10.13 SDK in Xcode 10. Any other ideas?

Thanks

Re: NSDrawer

[Georg Seifert]

But you can simulate a drawer by adding the extra view and resizing the window 
to fit. This is done automatically when you use autolayout (a stack view would 
be more useful than a split view) or a few lines of code when you do it 
manually.

Typing with multiple selections in NSTextView

Hi

Is it possible to make NSTextView to allow typing with multiple insertion 
points? One can set multiple selection and delete all of them at once. But 
typing only replaces the first range and ignores the other ranges.

Re: Very slow NSTableView

[Georg Seifert]

Any reason you set the tableview to be "Source List". Set it to regular and it 
will work perfectly. It seems that the NSPopUpButtonCell don’t like to be in a 
source list. Maybe you can subclass it and draw yourself?

undomanger performance

[Georg Seifert]

Hi

My app deals with an object tree that can have millions of leaves. It is 
possible to run an operation on all of them. Each will register its own change 
with the undo manager. The hole operation might tale a few second (the last 
line in the trace below). But after my operation is finished, there is another 
operation triggered by the system that takes much longer than the original task 
and it blocks the UI. It is directly linked to the undo registration, if I 
disable it, this does not happen.

Plugin bundle with Javascript

[Georg Seifert]

Hi,

I hope this it the right place to ask, if not can you point me the right 
direction.

Is it possible to build plugin bundles using Javascript? I know how to to that 
with ObjectiveC and python (with py2app) but could’n find anything about 
Javascript.

Georg

Re: Cocoa GUI app getting slower on MacPro or MacMini when disconnecting all screens

[Georg Seifert]

Macs still do that. I needed to get an adapter to get decent performance out of 
my headless macMini.

 You're not doing anything graphics or OpenGL-related, are you? At least in 
 the old days, Macs would turn off the GPU when no screen was attached, 
 meaning that you'd end up in software emulation when you did any openGL 
 calls. I thought that was different these days, but maybe this reminds you 
 of something you're doing that could cause this slowdown?

Re: UIColor in CoreData database into NSColor

[Georg Seifert]

That would only work it UIColor and NSColor would encode themselves in exactly 
the same way. Any guess what, they aren’t.

 So with that in mind, has anyone tackled a conversion process of reading in

Re: Blurry is the New Sharp

[Georg Seifert]

 
 I guess the best we can do as developers is to vote with our feet by not 
 adopting it in our apps. (I haven't had to deal with an OS X source list in a 
 while; I assume vibrancy has to be opted into? Or at least there's a way to 
 opt out?)

No, it is on by default and no way (that I know of, and I would be very happy 
to be proven wrong) to opt out.

Frame of views during awakeFromNib or restoration

[Georg Seifert]

Hi,

I see a problem on several places in my app. In awakeFromNib, in 
restoreStateWithCoder: or just after adding a view programmatically, the bounds 
aren’t in sync with the final size or with the super view. The relayout is done 
at the end of the runloop. This was not the case in 10.7 but is now in 10.9. I 
think I read somewhere about that but cant find it.

I have several things I need to do. One is to set the initial scroll position, 
another is that I want to manually restore some split views.

Thanks

 It's a bit more work, but if you supplied the service via a helper app 
 embedded in your app bundle, does that make it work?

I didn't see anything in the docs about how to set it up. Can you just set the 
post name to the helper apps name? who would be responsible for first starting 
the app? 

Are there any examples on how to set it up?

Thanks
Georg

 Hi,
 
 My app registers some services and they work just fine. Only if I invoke 
 then from within the same application, the app hangs. I tried with other 
 apps and they had the same problem.
 
 I searched the web for it but could not find anything.
 
 Is there anything I can do about it?

Custom view and NSText

[Georg Seifert]

Hi,

I have an view that acts as an text view by implementing the NSTextInputClient 
protocol. This works fine in 10.8 but leads to crashes in 10.9. The report says:

 Terminating app due to uncaught exception 'NSInternalInconsistencyException', 
 reason: 'All NSText methods must be implemented by subclassers.  They should 
 not call super.'

It seems to be related to the new input methods in 10.9. Like if you hold a key 
it will show a small popover that gives you some variants of that character 
(like accented characters) similar to the iOD keyboard. I tried to find any 
documentation about this...

The problem goes away if I link to the 10.9 SDK but I can't do that as I still 
support 10.6 and need to build on a 10.7 machine.

So can anyone point me in the right direction on how to implement the popovers?

below is a backtrace.

Thanks
Georg

 Hi,
 
 I have a problem. My app (documents based) does not support Lions Version 
 (returns NO in autosavesInPlace). This worked fine until I had to sandbox 
 my app. The problem is, that now the NSDocument autosaving tries to create 
 a file called My Document Name (Autosaved).myExtension next to the 
 document. But this is blocked by the sandbox. 
 
 Is there any way to extend the permission to the autosave file or can I 
 force NSDocument to always store the autosave files in the container?
 
 What's stopping you adopting autosave-in-place?
 
 I actually used autosave in place but my users did not like it at all. If 
 you have to open a lot files all the time just to check something, you do 
 not like that any mouse click might change your document and you are not 
 asked if you what to keep it.
 
 So let's try to nail down some of the real problems here:
 
 NSDocument's old autosave support periodically saves a copy of the document 
 as the user works. For new, unsaved documents, that's not a problem with the 
 sandbox.
 
 For existing documents it is though, because gets saved alongside the 
 original. The logic is that should the program crash or similar, and the user 
 is unable to re-open it in a normal fashion, that autosaved copy of the doc 
 is still sitting there on the filesystem in plain sight. The user can just go 
 and open it up and play with it.
 
 If you're absolutely desperate to keep using the old autosave system, it 
 might be possible to use 10.8's extra entitlements to declare that you need 
 write access to a specific filename alongside an existing one. But it's 10.8 
 only and I don't know if it could quite meet your needs.
 
 Another alternative would be to ask the system to autosave to an alternative 
 location which you do have write access to. Your users lose the ability to 
 easily spot the autosaved copy of the doc, but otherwise it should perform 
 fine.

Can someone give me a hint on how to do that?

 That said, I would strongly encourage you to adopt autosave-in-place. You 
 describe the problem in two parts:
 
 you do not like that any mouse click might change your document
 
 
 Surely this applies to either saving system?

No, with the new style autosaving, the file changes on disk without asking the 
user.

 you are not asked if you want to keep it
 
 So here's the real problem it seems; you run into customers accidentally 
 modifying documents. Normally they would be warned as they quit or close the 
 doc, but with autosave-in-place, that doesn't happen.
 
 Some good news in 10.8: users can turn on a system preference so that they 
 get effectively get back the warning behaviour. Closing a document will warn 
 you if there are unsaved changes. However, the file on disk will already 
 have been updated. That might bother them; I don't know.
 
 But more importantly, isn't this exactly what 10.7's concept of locked 
 documents tried to solve? If the doc hadn't been edited in a while, it would 
 be marked as locked. So the first time any edit occurred, a sheet popped down 
 asking if the user wanted to go ahead with the edit, duplicate the doc or 
 cancel.
 
 Was that not kicking in for your typical customers? Perhaps because the 
 document was too recently edited? 10.8 does throw this out of the window. But 
 what you could do is override -checkAutosavingSafetyAndReturnError: so that 
 it always returns NO when a doc is first opened. If your app is primarily 
 used as a viewer, that could be a neat way for you to always ask if the first 
 edit is intended.
 
Thanks
Georg

autosavesInPlace and sandbox

[Georg Seifert]

Hi,

I have a problem. My app (documents based) does not support Lions Version 
(returns NO in autosavesInPlace). This worked fine until I had to sandbox my 
app. The problem is, that now the NSDocument autosaving tries to create a file 
called My Document Name (Autosaved).myExtension next to the document. But 
this is blocked by the sandbox. 

Is there any way to extend the permission to the autosave file or can I force 
NSDocument to always store the autosave files in the container?

Thanks
Georg

 What's stopping you adopting autosave-in-place?
 
I actually used autosave in place but my users did not like it at all. If you 
have to open a lot files all the time just to check something, you do not like 
that any mouse click might change your document and you are not asked if you 
what to keep it.

xCode crash on validation for App Store

[Georg Seifert]

Hi,

I’m using xCode 4.3. If I try to validate my app prior to uploading it to the 
Mac App Store, it constantly crashes. 

I get a crash report that says: 
UNCAUGHT EXCEPTION (NSInvalidArgumentException): -[DVTFilePath compare:]: 
unrecognized selector sent to instance 0x409ab29c0

The same happens if i try to generate a installer package.

Is there anything I can do to circumvent this? Does anyone else has this 
problem?

Lion: unlocking a document

[Georg Seifert]

Hi,

I still have problems with my document saving behavior in Lion. 

If I open a file that my app can only read (CFBundleRoleType = Viewer) the 
state is set to locked. If I unlock it and do some changes, the autosave 
replaces the document file with a native file.

This is really not exactable. Not all data is read from the original (binary) 
file and so I need to keep the original.

Is there any way to prevent this. I would prefer that if the user unlocks the 
document, it actually is duplicated.

Lion: Lock documents and custom undomanager

[Georg Seifert]

Hi,

I have several undomanagers in my app. (I know that is unusual. Think of it as 
if you had a page layout app and every page has its own undo.)

This all works well except if the document is locked. Then the documents 
undomanager knows about this and prevents the change and generates a error. But 
my undomanagers are not in sync with the document. I do not find anything about 
that in the docs. So, is there any way to get the locked state of the document 
or to connect the undomanagers with the document?

Thanks
Georg

Re: ARC and 10.6

[Georg Seifert]

 I try to convert my app to use xCode 4.2 and ARC. My app uses several custom 
 frameworks and plugins. I used the migration tool to enable ARC for all of 
 them.
 
 As I still want to support Snow Leopard, I set the SDKROOT to 10.7 and the 
 Deployment Target to 10.6. But if I do that, on the startup of the app, I 
 get this in the console: 
 
 objc[9438]: Class __ARCLite__ is implemented in both [..]framework1 and 
 [..]framework2. One of the two will be used. Which one is undefined. // 
 removed the paths to frameworks...
 objc[9438]: Class __ARCLite__ is implemented in both [..]framework1 and 
 [..]framework3. One of the two will be used. Which one is undefined.
 objc[9438]: Class __ARCLite__ is implemented in both [..]framework1 and 
 [..]framework4. One of the two will be used. Which one is undefined.
 
 In the beginning I had only a few but now after converting all of my bundles 
 (around 20) I have 10 lines of those. The ARCLite stuff seems to be the 
 implementation to get ARC to work on Snow Leopard.
 
 That's right. The warning is annoying but otherwise harmless. The machinery 
 that makes ARC code work on older deployment targets was designed for apps, 
 and doesn't work well in frameworks. A future developer tools release should 
 fix this.

Is there a way to remove the code (for __ARCLite__) from the object files? Like 
you can remove the code for a certain architecture?

 That should not be a problem. BUT I also get this:

 And this just crashes the app. Does anyone has a clue what is going on here? 
 google is not very helpful.
 
 That's bad. What is the backtrace?
 

I had another look (and fixed the symbolic breakpoints that were lost) and it 
crashes when calling :

currBundle = [NSBundle bundleWithPath:currPath];
currPrincipalClass = [currBundle principalClass];

The bundle (one of my plugins) links agains Cocoa.framework in the 10.7 SDK and 
has ARC enabled.

I fixed it. I forgot to specify a Principle class for some of my plugins. This

Re: My services in my own app

[Georg Seifert]

Yes, I’m on Snow Leopard.

I just had a another look at the specs. there is something about a .service 
bundle. Can I put one of this in my .app bundle? And how do I register it?

Thanks
Georg

 You didn't indicate what version of Mac OS X you were running under.
 
 If this is happening under Snow Leopard, then this is a known issue in
 Snow Leopard that Apple fixed in Lion.
 
 The only work around I know is to put the service code in a separate
 (background) application that then calls back into your app to do
 whatever task you need it to do.
 
 Mark
 
 Hi,
 
 My app registers some services and they work just fine. Only if I invoke 
 then from within the same application, the app hangs. I tried with other 
 apps and they had the same problem.
 
 I searched the web for it but could not find anything.
 
 Is there anything I can do about it?

document saveing in Lion

[Georg Seifert]

Hi,

I have a problem and can find the right terms to search for it to solve my 
problem.

I have a app, that can read several documents as but can’t save them, it has a 
native file format is can save to. If I open such a file, it shows a locked 
in the title bar. If I unlock it and make some changes and close the document, 
it just saves to the same url as the opened file. As it saves in another file 
type, the file is rendered useless as the extension is wrong now. 

I suppose it should bring up a save panel either when I unlock it or when I 
close it, much like it does when duplicating.

Can someone shed some light on this?

Re: document saveing in Lion

[Georg Seifert]

Sorry for replying to my own post.

Just as I wrote this, I found the File Type Fixing in -[NSDocument 
saveToURL:ofType:forSaveOperation:completionHandler:] in the release notes. 
But this behavior is not acceptable. The read-only files should not be deleted 
but the user should be asked for an place to save the new file.

 Hi,
 
 I have a problem and can find the right terms to search for it to solve my 
 problem.
 
 I have a app, that can read several documents as but can’t save them, it has 
 a native file format is can save to. If I open such a file, it shows a 
 locked in the title bar. If I unlock it and make some changes and close the 
 document, it just saves to the same url as the opened file. As it saves in 
 another file type, the file is rendered useless as the extension is wrong 
 now. 
 
 I suppose it should bring up a save panel either when I unlock it or when I 
 close it, much like it does when duplicating.
 
 Can someone shed some light on this?

Re: diable localization

[Georg Seifert]

Hi,

Many thanks. That worked perfectly. 

I need this to allow my users to disable localization.

I use this:

- (IBAction) setDisableLocalization:(id) sender {
if ([sender state] == NSOnState) {
[[NSUserDefaults standardUserDefaults] setObject:[NSArray 
arrayWithObject:@en] forKey:@AppleLanguages];
}
else {
[[NSUserDefaults standardUserDefaults] 
removeObjectForKey:@AppleLanguages];
}
}

After a restart all is fine.

 Just read http://homepage.mac.com/mmalc/Stepwise/Internationalization/
 it mentions the command line switch:
 
 $ /Applications/TextEdit.app/Contents/MacOS/TextEdit -AppleLanguages
 (Spanish)
 
 this is a normal default, so
 
 $ defaults write com.apple.TextEdit AppleLanguages (Spanish)
 
 should work, or set the argument/default inside the main function before
 calling NSApplicationMain
 
 In Xcode, you can also pass -AppleLanguages as an argument to your
 executable.  This lets you debug in any language, regardless of your
 preferred languages in System Prefs.

Re: Master Detail

[Georg Seifert]

No, I meant the detail view changes the value according to the switch. And in 
my case it is actually a array in the person class and the switch determines if 
it is the first, the second or the third value to display. 

in the TableView I can do that with the datasource methods.

 You should be able to rebind the detail view table column according to the 
 property you want it to display:
 
   [tableColumn bind: @value toObject: arrayController withKeyPath: 
 @address property name 1 or 2 options: ...];
 
 Or, you could create one table column for each address, and reconfigure the 
 table to show the appropriate column:
 
   [table addTableColumn: tableColumn1];
   [table removeTableColumn: tableColumn2];
 
 Or, you could just hide/show columns:
 
   [tableColumn1 setHidden: NO];
   [tableColumn2 setHidden: YES];
 
 Or, you could have two separate tables, and hide/show the appropriate table:
 
   [table1 setHidden: NO];
   [table2 setHidden: YES];
 
 It's also possible to create a derived data model address1OrAddress2 
 property, but this is only useful if the address mode doesn't need to be set 
 in different ways for different views of the data.

disable animation of default button

Hi,

I have a subclass of NSButton. The bezel style is set to Push. If the button 
has the return key equivalent and becoming the default button (drawn blue) the 
- (void) drawBezelWithFrame:(NSRect)cellFrame inView:(NSView *)controlView 
method gets called over end over again. In the standard implementation this 
makes the button pulse.

I want to disable this for my subclass but can’t find the case of the redraw.

 If I were writing this today, I would use views. I would make it so

 The rest of the collection view would be empty. As the user scrolled,
 I would create new views for the newly exposed items and add them
 dynamically. If view creation is too slow for this, I would implement
 some sort of view reuse mechanism that could load new data into the
 views that have scrolled off screen. This is basically how UITableView
 works on the iPhone, and if it can get good performance on that
 platform, you ought to be able to do great on any Mac that can run OS
 X.
 
I understand.

Jumping through some more holes, I did manage to implement most things I needed.

On thing I can’t figure out, is how to implement extending the selection with 
the shift key. Only the command modifier works by default.

Re: Custom control and cells

[Georg Seifert]

Hi,

 In what way do you believe a custom NSCell-based replication of 
 NSCollectionView will perform better than NSCollectionView itself? What 
 performance issue have you seen? Are you sure the problem lies with 
 NSCollectionView and not your own code surrounding it? (I.e., have you 
 Sharked your application?)

I have Sharked it a lot.

I have bound the CollectionView to a array with several hundred to several 
thousand items. There is a sidebar which filters the content, displaying a 
small subset of the content. Every time I change the filter, all previously not 
visible views are recreated. This may take several seconds. I could mostly 
avoid this by caching the item and the view (jumping through holes to find out 
how to do so). One half of the initial loading of the document is taken from 
the NSCollectionView. 

So the main problem is the time the CollectionView needs to archive and 
deserialize the item view prototype (I even improved this by creating the view 
in code in newItemForRepresentedObject:).

I just Sharked it and stoped the time again (on Snow Leopard) and it turns out 
that my optimization does work very well, taking the time to initiate the 
collectionview from 1 second to 0.1 sec. But the optimization does only work 
on SL. So all my users with Leopard and PowerPCs (there are several still using 
them) have to wait.

Saving of the collectionViewItems in the data object (This was one of the holes 
I jumped through), albite not working to cache the items in Leopard, can be 
used to get the frame of the view for the item in Leopard. Or is there a (even 
private) method to get this directly from the collectionView? (I have to check 
for the systems version number anyway)

Georg

using UTF-32 in NSString.

[Georg Seifert]

Hi,

Does anyone has information on how to use Unicode code points higher than 
0x.
I need to add some supplementary multilingual plane code points to a NSString.

I can use something like this: 
NSString *aString = @\\u0001ABCD; //this prints fine but the [aString 
length] is 2

But if I have the unicode value as a int (unichar is to small)
int Char = 0x1ABCD;
NSString *aString = [NSString stringWithFormat:@%C, Char]; //The 
resulting string contains one character with a unicode value of ABCD.

What is the recommended way to use/create UTF-32 strings in Cocoa.

(NSTextField: 0x19300390), expected GlyphIconView: 0x19300320


I did wrapped the drawing code in [NSGraphicsContext saveGraphicsState/ 
restoreGraphicsState];


Simplified it looks like this:
[NSGraphicsContext saveGraphicsState];
[[NSColor grayColor] set];
NSRectFill([self bounds]);
[NSGraphicsContext restoreGraphicsState];

If I remove drawRect: from my class, everything works fine.

I tried to remove the focus of the textField prior to setting represented.name 
, but I cant get the send action of the textfield to work.


Can anybody pleas help me with this?

Regards
Georg

enable/disable/check file Sharing from code

[Georg Seifert]

Hi,

Is there a way to enable and disable file sharing from code.

I only found this:
/usr/sbin/AppleFileServer
It seems to work but if I use it, the Sharing prefPane does not show  
the enabled state.


And is there a way to check if file sharing is running?

Are there recommended approaches to switch the other sharing services  
(internet, printer, Screen sharing) from code.


Thanks
Georg

Re: enable/disable/check file Sharing from code

[Georg Seifert]

Is there a way to enable and disable file sharing from code.


Almost all background services are universally controlled by  
launchd. See man launchctl, launchd, et al.


This is not exactly my problem. I can start file sharing with just  
calling /usr/sbin/AppleFileServer. My question was how to to it that  
would also check the checkbox and respect the settings in the sharing  
pane (enable afs, smb and ftp it is selected in Options...).

no mouseDown on dismissing context menu

[Georg Seifert]

Hi,

If I show a context menu in my view and then click somewhere in the  
view, mouseDown for the view is not called. Subsequent mouseDragged  
are triggered.


The view returns YES in acceptsFirstMouse and acceptsFirstResponder.

What do I miss?

Re: pulldown in custom NSCell

[Georg Seifert]

Hi corbin and Andreas,

Both approaches look promising. I will play with them.

Thanks
Georg



What I found is that the Cell, in its drawwithFrame method, adds  
subview to the TableView and this subview handles all the drawing  
and handling. Is this appropriate or is there a better solution.


In case you don't need a fully fledged TableView, have a look at  
this and see if it fits your bill:

Custom grid view

[Georg Seifert]

Hi,

I try to implement a control with several  NSTextCells in it.

I have problems starting the edit mode.

So fare I tried this (in the control’s mouseDown):
NSText * textObj = [[self window] fieldEditor:YES forObject:_editCell];
[textObj setEditable:YES];
[textObj setFieldEditor:YES];
[textObj setSelectable:YES];
	[_editCell selectWithFrame:Frame inView:self editor:textObj  
delegate:self start:0 length:32000];			

[_editCell setUpFieldEditorAttributes:textObj ];
	[_editCell editWithFrame:Frame inView:self editor:textObj  
delegate:self event:theEvent ];


What else should I implement. Is there any sample code (I did searched  
the web but found nothing)?

promised to export the UTI in the next version but this will take  
another year or so).


For now I use the dynamic UTI. This works so far. How save it is to  
use the dynamic UTIs.


But, is there any way to define the UTI from within my QuickLook plugin?

Don't use a dynamic UTI.  You should add a proper UTI declaration to
your QL Plugin's Info.plist.  Declare it in  
UTImportedTypeDeclarations.

Make sure it matches what the other app will use.



I did tried this earlier and it didn’t worked – until now that I tried  
it again.

Fwd: Memory management in QuickLook plugin

[Georg Seifert]

As alway I didn’t send it to the list...



Use Zombies and Instruments.



http://www.corbinstreehouse.com/blog/index.php/2007/10/instruments-on-leopard-how-to-debug-those-random-crashes-in-your-cocoa-app/



I do this all the time, but can’t figure out how to use Instruments  
with quicklookd. I can run it but how do I supply the argument.  
If I use qlmanage everything works fine.




Unfortunately, I don't know -- sorry!

I would suspect that if it is a consistent memory issue, running  
with NSZombiesEnabled and glmanage should make it happen consistently.

Memory management in QuickLook plugin

[Georg Seifert]

Hi,

I’m developing a QuickLook plugin for a custom binary file format.

As long as I did not cared about memory leaks everything was fine.  
Then I fixed the leak with the help of Instruments. Everything runs  
fine from xCode and Instruments but now it crashes if I run the plugin  
from the finder.


I have set up a custom executable with /usr/bin/qlmanage and the  
argument -p path/to/my/file.


Any advice is very welcome.

Do you mean quicklookd crashes but qlmanage does not?

Yes.

argument -p path/to/my/file.

We lack information here. We'd need to know where it is crashing.


This is definitely a memory problem. Sometimes it is about memory  
being double released and sometimes things like:
20.05.09 13:42:00 quicklookd[38490] [QL ERROR] Preview request  
generator for QLPreviewRequest /Users/georg/... raised '*** - 
[NSCFString saveGraphicsState]: unrecognized selector sent to instance  
0x138880'


the only call to saveGraphicsState is: [NSGraphicsContext  
saveGraphicsState];


So this seem exactly what happends with wrong retain/releases. The  
Problem is, I cannot debug it because in the debugger everything is  
fine.


Thanks

custom formating of NSAttributedString

How do I connect my controls (pulldown or checkboxes) with the

(is there a way to render a sting with it?)
- activating the font locally, render the image and deactivate it.  
(this is a bit overkill I suppose (and I didn’t tried it))

- using a framework (like freetype)

And it may conflict with activated fonts.

If it's a regular, supported (but not activated) font file, you can  
do something like this (this is what I do actually):


#import Cocoa/Cocoa.h
#import ApplicationServices/ApplicationServices.h

/* ... */

NSString* fontsFolder = [[[NSBundle mainBundle] resourcePath]  
stringByAppendingPathComponent:@/Fonts];

NSURL* fontsURL = [NSURL fileURLWithPath:fontsFolder];

OSStatus status;
FSRef fsRef;
CFURLGetFSRef((CFURLRef)fontsURL, fsRef);
status = ATSFontActivateFromFileReference(fsRef,  
kATSFontContextLocal, kATSFontFormatUnspecified, NULL,  
kATSOptionFlagsDefault, NULL);


NSFont* myFont = [NSFont fontWithName:@My Font size:12.0];
[mWelcomeLabel setFont:myFont];

/* ... */

In this example, it assumes that your font files are in the  
application bundled under the Resources directory in a directory  
named Fonts, so basically:


/Applications/MyApplication.app/Contents/Resources/Fonts/MyFont.dfont

BTW, this call doesn't require linking to the full Carobn framework,  
nor does it actually activate the font in the Font Book... just for  
this instance of your application.


HTH, Jason

Re: menu with checkbox

[Georg Seifert]

That what exactly what I was looking after. I think it would be not to  
strange in the context where it occurs in my app.


The normal selection behavior is for selecting the active layer in my  
view. The additional checkbox should allow to blend in/out the other  
layers.


I couldn’t think of a better/more intuitive way to achieve this.

To implement this, I just thought about using a tableview in the popup  
menu. There we have very similar behavior. You have a selection and  
checkboxes. And clicking the checkboxes does not change the selection.

No, a checkbox would look rather different... here, let me mock up  
what I was thinking the OP was asking for.

If what they're after is simply the check marks that Safari and  
other applications use in menus, you can get that with -[NSMenuItem

Re: menu with checkbox

[Georg Seifert]

My unsolicited advice: Don't use a popup menu; embed the table view  
in a palette. Popup menus with multiple controls in them are not a  
standard UI component, and are likely to generate significant user  
confusion. (Doubly so when there's two levels of checked-ness  
involved.)



I just thought a bit about the usage of controls in menus.

apple gives a example of how to use it: 
http://developer.apple.com/samplecode/MenuItemView/index.html
this breaks the click-drag-release behavior

and another example is the color-label selection in Finder. And this  
is useable with click-drag-release.


So if I find a way (and I think I have) to allow click-drag-release  
usage, then I should not confuse my users to much.

Re: Rounding very small numbers.

[Georg Seifert]

cant you just multiply with 1, round it and divide 1?

Hey all,

I've been scouring the archives, but coming up without any solution  
that

seems to work in my application. Here is the issue:

I have some tiny numbers, like -0.00116916, for example, that I  
want
rounded to the 5th decimal place or so. -0.0 is plenty precise  
for my

purposes.

I attempted to do that with the following code:

NSDecimalNumberHandler* roundingBehavior = [NSDecimalNumberHandler
decimalNumberHandlerWithRoundingMode:NSRoundPlain scale:5];

NSDecimalNumber *roundFloat = NSDecimalNumber alloc]
   initWithFloat:0.00023]
   decimalNumberByRaisingToPower:5]
   decimalNumberByRoundingAccordingToBehavior:
roundingBehavior];

... but I'm getting the following warning:

NSDecimalNumberHandler may not respond to decimalNumberHandler...

... and in addition, my code crashes when I attempt to run with this
warning. XCode seems comfortable suggesting the
decimalNumberHandlerWithRoundingMode method, but it does not seem to  
work.
All of the code examples I see seem to have something exactly like  
this, but

it isn't at all working with my project.

Do I need to implement a protocol? I'm pretty lost. Am I going about  
this
totally the wrong way? Is there a much easier way to round? I don't  
really

need it stored, should I be using C methods? (How do I do that?)

Thanks!

menu with checkbox

[Georg Seifert]

hello,

I have a NSPopupButton. What I need is that each item has a checkbox  
in front of its label. The menu needs to be selectable like with any  
normal NSPupupButton but when I click the checkbox it should just  
check the box but should not change the selection.


Does anyone can help me with this. I cannot find anything about this  
on the net.


Thanks
Georg

Re: call setContentBorderThickness:forEdge: in Tiger

[Georg Seifert]

Hello Johan,

this was the mystery: Why it crashes with NSMinXEdge when I only use  
NSMinYEdge. But the comment from Shawn helped me find the right  
answer.


I have to set the Base SDK to 10.5 and the deployment SDK to 10.4.  
This, at least, solved the crash on Leopard. I cannot test it on  
Tiger, but it shall work.


Many Thanks for all your help,
Georg


Hello,

I have a problem:

- (id)initWithContentRect:(NSRect)contentRect styleMask: (unsigned  
int)windowStyle backing:(NSBackingStoreType)bufferingType defer: 
(BOOL)deferCreation

{
BOOL useTextured = YES;
	if([self  
respondsToSelector:@selector(setContentBorderThickness:forEdge:)]) {

windowStyle ^= NSTexturedBackgroundWindowMask;
useTextured = NO;
}

	self = [super initWithContentRect:contentRect  
styleMask:windowStyle backing:bufferingType defer:deferCreation];

if(!useTextured)
{
[self setContentBorderThickness:27.0 forEdge: NSMinYEdge];
}
return self;
}   

if I compile against the 10.5 SDK everything work fine. But if I  
use the 10.4 SDK it crashes:
*** Terminating app due to uncaught exception  
'NSInvalidArgumentException', reason:  
'setContentBorderThickness:forEdge: may not be called with  
NSMinXEdge'


Your error message says NSMinXEdge, but your code says  
NSMinYEdge Is that just a transcription error in mail? I think  
fixing that will lead you to your answer. Also, are you sure xoring  
is what you want to do? With XOR, you're unconditionally toggling  
the NSTexturedBackgroundWindowMask bit. Perhaps you mean to do that  
though.


Good Luck -

Re: call setContentBorderThickness:forEdge: in Tiger

[Georg Seifert]

Hi Matt,

Your code does the same than mine. The code in question is called only  
on Leopard. But the problem occurs only there. Is seem that if you  
have compiled against 10.4 you cannot call functions from the 10.5  
SDK


Is there some compatibility build setting or something else?
Georg


Hi Georg,

How about doing something like this? (typed in Mail, so check for
typos). Using the preprocessor macros should also be a *bit* more
efficient, since it won't be doing any checks at runtime.

{
#if MAC_OS_X_VERSION_MAX_ALLOWED = MAC_OS_X_VERSION_10_5
windowStyle ^= NSTexturedBackgroundWindowMask;
#endif

self = [super initWithContentRect:contentRect styleMask:windowStyle
backing:bufferingType defer:deferCreation];

#if MAC_OS_X_VERSION_MAX_ALLOWED = MAC_OS_X_VERSION_10_5
[self setContentBorderThickness:27.0 forEdge: NSMinYEdge];
#endif

return self;
}

@try @catch

[Georg Seifert]

hello,

is it recommended to use @try .. @catch blocks as flow control like it  
is used in Python. They say explicitly to use it rather than do a lot  
of test before just try if it works to look after it only if it fails.


I could imagine something:
- (id) layerInstance {
if ([[layerInstancesController selectedObjects] count]  0) {
return [[layerInstancesController selectedObjects] 
objectAtIndex:0];
}
return nil;
}
to look like:

- (id) layerInstance {
@try {
return [[layerInstancesController selectedObjects] 
objectAtIndex:0];
}
@catch {
return nil;
}
}

it should run faster if I do not have the if clause? Or are there any  
drawbacks?


Regards
Georg
