Darker Round Rect NSButtons

[Colin Doncaster]

My apologies for what may be a seemingly obvious and simple question,  
I want to make sure I'm not overlooking anything though.  I have been  
trying to poke around the internet for examples of what I'm looking  
for but have come up empty so far.


I'd like to use the Round Rect buttons with a colour scheme similar to  
that used by applications like Pixelmator - if you look at http://www.pixelmator.com/i/layers-front.png 
 you can see what I mean.  It's a darker more colour sensitive  
scheme.  I was using the CALayer effects in Interface Builder to apply  
an exposure adjustment to the buttons that sort of gives me the  
correct look, but I can't help wonder if I'm missing a simple setting  
somewhere.


I figure I could either subclass NSButtonCell or make the changes via  
an -awakeFromNib call in the document class but, as it appears a few  
applications seem to be using this style of button, figured it  
wouldn't hurt to ask.


On that same note, would the horizontal slider shown in that image use  
a similar override?


Thanks

Suggesting a user name for NSURLConnection

[Lakshmi Vyasarajan]

Hello,

I have an application that interfaces with delicious. I have created  
an account in delicious for testing purposes. In the process of  
switching between these accounts, my keychain now has two entries for  
delicious API URL.


When I am calling the service I know which user the call is made for,  
but there doesnt seem to be any way to tell NSURLConnection to lookup  
the credentials for the given user name. I really want to avoid  
sending the URL with user name and password.


I am using sendSynchronousRequest to perform this operation.

Is there a way to suggest the user name or do I have to resort to more  
low level API to get this working?


Thanks
Lakshmi.

NSArchiver and NSKeyedArchiver

[D.K. Johnston]

I wrote a class that conforms to the NSCoding protocol. I used  
encodeObject:forKey and decodeObjectForKey: in the required methods.


By mistake I used NSArchiver to archive one of the class instances. It  
compiled with no trouble; but then, not surprisingly, I got an  
exception when I ran it:


*** Terminating app due to uncaught exception  
'NSInvalidArgumentException'
reason: '*** -encodeObject:forKey: only defined for abstract class.  
Define -[NSArchiver encodeObject:forKey:]!'


The fact that I should have used NSKeyedArchiver instead of NSArchiver  
isn't obvious from the message.  (At least it's not obvious to me.)  
Can anything be done to ensure users of the class use NSKeyedArchiver,  
besides putting a comment in the header file?


Thanks etc.

how to tell if my app is visible.

[Memo Akten]

Hi All, i have an app which is running on the desktop :

windowRect = [[NSScreen mainScreen] visibleFrame];
	window = [[NSWindow alloc] initWithContentRect:windowRect  
styleMask:NSBorderlessWindowMask backing:NSBackingStoreBuffered  
defer:NO];

[window setFrame:windowRect display:NO];
[window setOpaque:NO];
[window setBackgroundColor:[NSColor clearColor]];
[window setMovableByWindowBackground:NO];
[window setLevel:kCGDesktopIconWindowLevel];
[window setAcceptsMouseMovedEvents:YES];

The app is running a quartz composition, which has custom QCPlugin in  
it.


My first problem was, that even where there are other app windows  
(e.g. finder) on top of my app, the app (the quartz composition)  
responds to mouse events whilst its in the background (e.g. I want  
animations to trigger if the mouse is over something, but not if its  
obscured by finder or safari etc.). So I did a check to see if my app  
was active or not ([[NSApplication sharedApplication] isActive])  
before responding to mouse position and events.


That works to some degree, but if I have a window to the side and my  
app is fully visible, it doesn't respond to mouse position and events  
- because its not active. But is there a solution to this?

Try looking into using the NSApplication delegate methods that inform

A comment in the header is a pretty good way to go, and a fairly
standard technique. Understanding the error you saw will get easier
with time. It's telling you that you're sending a message to an object
that doesn't understand it. Some inspection shows that it's a keyed
archiving message, and you're sending it to NSArchiver, so the rest
flows from there. Now I don't doubt that it was non-obvious for you
the first time around, but you'll probably only have that difficulty
once.

However, for extra paranoia, Mike Abdullah's technique of checking
explicitly can let you give yourself a better error message.

My problem is not so much with detecting when the application is

while the application is not active, but does not have another window

Sounds like your end goal is not to detect whether your window is
visible, but rather to limit mouse events to visible regions.
NSTrackingArea on 10.5 can do this. If you need to support 10.4, you
may be able to do the same thing with NSView's old-style tracking rect
support.

Australia Cocoa consulting/training?

[Devraj Mukherjee]

Hi all,

May be the wrong place to post this message but didn't know where to start.

Are there any Australia based Cocoa developers on this list who would
be willing to conduct a one day consulting session to sort out some
issues with an application we are building?

Issues revolve around user interface elements / bindings mostly.

Thanks.

You need to call -setNeedsDisplay on the tiled layer. Doing so on the  
scroll layer will only affect its own contents.

[ANN] Swfdec, new developer tool

[Nick Zitzmann]

(DISCLAIMER: I'm speaking only for myself here. I usually am, but you  
already knew that, right?)


Today I published the source code and binaries for a new framework,  
called Swfdec. You can use it for free in your applications (it's  
LGPL'd) to run Flash animations. Swfdec comes with one NSView  
subclass, SDFlashView, that runs an animation given a URL.


So why use Swfdec? Well, it's easier to set up and use than a WebView  
if all you want to do is run a Flash animation, and it also uses a lot  
less memory than WebView. In addition, it supports the new garbage  
collection feature of Objective-C, and it'll support 64-bit  
addressing, too, once I port some ATSUI code over to something that  
works in the 64-bit environment. It should also be possible to port to  
the ** and  *, but we can't discuss that in public.


But the most important thing is, it uses its own Flash engine and does  
not use Flash Player, so Swfdec will run on computers where Adobe  
Flash Player is not allowed (e.g. some office environments).


This is a sneaky-peek (not final) release and video is not implemented  
yet (and I need some help getting it to work), but other than that,  
your animations should Just Work™:

box) 'cos if you try, the close box will end up half on and half off  
the vertical titlebar!  Not great!  If you really want to do this,  
and make it look good then (a) it's probably quite a bit of work and  
(b) you'll very likely need to give your window a custom frame class.


Tried this today and in addition to the close box being the wrong size  
and in the wrong position if passing NSClosableWindowMask to the  
styleMask it also does not become titled if you send:


[weirdWindow setTitle:@"Window Title"];

At this point I think the only thing to do is to create a borderless  
window and create my own left side title bar (using +[NSWindow  
standardWindowButton:] to get small standard window buttons). If I  
manage to implement such a thing I will try to get permission to open  
source it.


Thanks for the fun diversion,
Nick

NSImage with alpha

What about creating a new image of the appropriate size, locking focus  
on that, and then use one of the -draw... functions that take a  
"fraction" argument (for the resulting opacity)?

I think you need to define "wipes out" a bit more precisely.

Developer needed

[alex]

Hello,

Sorry for the intrusion but I'm looking for someone to take over the  
iPhone application that I wrote for AT&T's yellowpages.


I'm looking for someone who has commercial (consumer) software  
experience. And someone who enjoys solving problems in a elegant and  
expedient manner.  I am not a recruiter so please don't take this  
opportunity to spam me with your resume.


The application you would be working on is called YPmobile and it is a  
free download from the AppStore.  Please be sure to play with this  
application before contacting me if you are interested.




Here are some of the requirements for this gig:

- Solid experience with Obj-C and familiar with UIKit.

- Minimum of 3 years commercial software experience-  Ideally, tell me  
that you worked on some  product or project I've actually heard of.


- Proven ability to ship commercial applications on time.

- Be a genuinely polite, ethical, nice guy/gal who can handle  
differing points of view with professionalism and be motivated to  
convince others of your genius.  Engineering is never easy but I'm  
looking for people who make it look easy-  people who enjoy  
abstractions and can operate efficiently within them.


- Generally be creative or good at user interface code and also good  
at handling criticism of such code.




I will request a sample of your work, be prepared to show off your  
best code that represents your coding style.  If you cannot provide a  
sample (no matter how small) do not email me.  I am not interested in  
any candidates that cannot (or will not) provide a sample of their work.


Please do not apply if this job sounds weird- or this description is  
too oblique for you-  working under my direction will be weird and  
entertaining (I hope).  It will also be massively rewarding and fun.   
The pay is excellent and I never want any of my staff to work in their  
off time.


Please reply directly to me [and not the list] if this interests you  
in any way.
The position is located in Glendale, CA (Los Angeles) and is a full  
time position.


Thanks and sorry for coercing this list.

best,
alex

I do not represent AT&T or Yellowpages.com so please don't sue them  
for something I wrote here.

Always allowing drags from WebView inside a global NSPanel

[Nick Beadman]

I have a NSPanel which does not hide on deactivate [1] and has a  
WebView embedded in a NSTabView. All of this resides in an "agent"  
application (LSUIElement is set in Info.plist). The objective is to  
have a small globally accessible web site where the user can drag  
images into other applications.


The problem I am having is that to drag out of the WebView the panel  
has to be main (i.e. the close/minimize/zoom buttons are filled in).  
However, if you hold down the command key, the drag out of that window  
works fine.


Where do I start looking to make this work without having to hold down  
the command key?

Thanks,
Nick

HITheme is currently undecided. We did hear from multiple developers

-eric schlegel



Has the fate of HITheme has been decided, and it is going to be the  
theme drawing API for OS X [1] going forward? The only documentation I  
have found is the header HITheme.h and nowhere in there is mentioned  
it being a 32-bit only API. Given that it uses Quartz parameters this  
makes sense but I want to be sure before I spend time working on an  
under-documented API, especially as it is in Carbon framework. Looking  
at HIView.h it appears to be a safe because those API are documented as:


*  Availability:
*Mac OS X: in version 10.2 and later in Carbon.framework  
[32-bit only]


Thanks,
Nick

[1] Note I said OS X, not Cocoa, not Carbon and not Mac OS X, although  
I will take an answer for any and all of those technologies :-).

[Q] Custom NSFormatter and IB's Cocoa Simulator

[JongAm Park]

Hello.

I tried making my own custom NSFormatter by following the guide, 
"Interface Builder Plug-In Programming Guide"


However, when I tried my NSFormatter subclass using the "Simulate 
Interface" menu item of the Interface Builder, it rasied :


An uncaught exception was raised
*** - [NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of 
class (JAStringFormatter)


*** Terminating app due to uncaught exception  
'NSInvalidUncarchiveOperationException', reason:
'*** - [NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of 
class (JAStringFormatter)'


Can anyone tell me how to solve this problem?

Also, I would like to ask if 
"attributedStringForObjectValue:withDefaultAttributes:" is really 
requried to be overriden.
The document says, "To subclass NSFormatter, you must, at the least, 
override the three primitive methods:".


Thank you in advance.

Properties and bindings

[D.K. Johnston]

I'm trying to learn how to use bindings. MyObject has an NSInteger  
myInt. I used @property and @synthesize to make myInt into a property.  
In IB I bound an NSTextField to the myInt property. Now when I do this:


self.myInt = 123;

when initialising MyObject, the value shows up in the text field. But  
if I do this instead:


myInt = 123;

the textfield just shows '0'. What's happening here?

NSURLDownload resumeData always nil

[Andrew Zahra]

I am experimenting with the resume functionality in NSURLDownload, however I
always get nil back when I call resumeData. I have tried a couple of
different sites and then tried using wget to get the files. wget resumes the
files fine, so I think I am doing something wrong.
This is the code in question, which is a modification of the Downloader
example supplied by Apple:

download = [[WebDownload alloc] initWithRequest:[NSURLRequest
requestWithURL:URL]
delegate:self];

[download setDeletesFileUponFailure:NO];

resumeData = [download resumeData];

if (resumeData == nil)

{

NSLog(@"No resume data :(");

}

Any suggestions?

thanks,
Andrew

The self.myInt runs through the accessor method that was synthesized  
by the runtime, and a KVO notification was sent out. Setting myInt  
directly circumvented the accessor, so no KVO notification was sent,  
since the change occurred behind the back of the runtime. Without that  
KVO notification, the text field doesn't know myInt changed.

Re: Properties and bindings

[Roland King]

when you do self.myInt under the covers you're really doing [ self  
setMyInt:123 ], and that method is KVO compliant so it fires the  
property change notification the textfield needs.


myInt = 123 just sets the variable directly and skips the property  
change notification.

Others already answered this, but if (for some reason) you want to do  
this manually, you can enable the KVO as so:


[self willChangeValueForKey:@"myInt"];
myInt = 123;
[self didChangeValueForKey:@"myInt"];
