deviceID from ICDevice in Cocoa
How can I retrieve the deviceID from the ICDevice just like it's output by
NSLog. The name can easily be retrieved with addedDevice.name, but
addedDevice.deviceID doesn't work.
- (void)deviceBrowser:(ICDeviceBrowser*)browser
didAddDevice:(ICDevice*)addedDevice moreComing:(BOOL)moreComing {
NSLog(@deviceBrowser:didAddDevice:\n%@\nmoreComing: %d\n,
addedDevice, moreComing);
}

Re: textfield problem

IB instantiating objects
I'm working on developing a Pascal Objective-C bridge like RubyObjc and have run across a problem I can't seem to work around with IB. I very new to Cocoa btw, so I hope this makes sense. Maybe I'm asking in the wrong place also. ;) I have noticed that when a nib is loaded it must allocate an instance of the class that I added to the nib and when actions are sent to their target (by dragging connections to that class), THAT instance is used as the self parameter (the first) in the Pascal function (this parameter is hidden in Objective-C code). That means I have no opportunity to set an instance variable that contains a reference to the Pascal object, and thus access it's instance variables and methods. Is there anyone who is aware how this was accomplished by the other bridges or if I can force IB to not instantiate the classes, or maybe replace the instance with my own? It seems like I need a way to access the instances of those classes inside the nib but I don't think that can be done. Any ideas are greatly appreciated. Thank you.

Re: IB instantiating objects
Great, thanks. I almost have this working but with one little problem. 1) I add the init method to my class 2) When init is invoked from the NIB I call objc_msgSend with the selector init which returns the new instance of the class (retrieved from objc_getClass) I previously registered with the runtime and added instance variables. 3) I call class_getInstanceVariable to get the instance variable I need to assign the reference to the wrapper class. Here class_getInstanceVariable returns nil which it never did before. I'm using the 1.0 runtime for now btw, but I get the class of the instance by using the isa field of the structure and give that class as the parameter to class_getInstanceVariable. This worked with other objects so I think I may have created the instance wrong. Is simply sending init to the class not enough? I tried calling alloc also but it entered into an infinite loop. Also, do I need to being the self parameter in this process that is the first parameter in the method? I find it strange I have another instance of this object I'm trying to replace, what should I do with it? Is it leaking memory? Thanks for helping with this I appreciate it.

Re: An Example NSStatusItem with a menu
it is easy. Just set the properties of the NSStatusItem. Then don't
state setMenu. Instead call setAction with a method.
[status_menu setAction:@selector(menuClick:)];
In that method you can add all the items you want. At the end of the
method you have to call the popUpStatusItemMenu method to display the
method.
This way you can enable or disable items depending on app variables
- (IBAction)menuClick:(id)sender
{
NSMenu *menu=[[[NSMenu alloc] initWithTitle:@] autorelease];
[menu setAutoenablesItems:false];
NSMenuItem *it=[[[NSMenuItem alloc] initWithTitle:@Prefs
action:@selector(showPrefs:) keyEquivalent:@] autorelease];
if([win_preferences isVisible])
[it setEnabled:false];
[it setTarget:self];
[menu addItem:it];
it=[[[NSMenuItem alloc] initWithTitle:@Quit
action:@selector(closeApplication:) keyEquivalent:@] autorelease];
[it setTarget:self];
[menu addItem:it];
[status_menu popUpStatusItemMenu:menu];
}
Hope it helps

Re: List Running apps and windows
Well, finally solved. No need for AXIsProcessTrusted. The problem is
that the data stored in the NSArray was comming from an CFArray and
was not printed with NSLog. But it was there.
I want to use the info to do something like witch.
Thanks a lot for your tips.
I'll post some code latter if someone ask for it. There are lots of
info to make and application accesible but no info to make an
assistive app.

Guesses?
You need to be running as root to call AXMakeProcessTrusted().
I wrote a post on my blog with some code to do that:

Re: List Running apps and windows
PD: I have tried the UIElementInspector code and it also says that the
App is not trusted, but it succeeds in geting other apps info. Instead
when I run
AXUIElementRef ref=AXUIElementCreateApplication(pid);
AXUIElementCopyAttributeNames(ref, (CFArrayRef *)theNames);
theNames is empty.
Why is this happening?

Each application has its own private address space, so including another
app's windows in your app's window list doesn't make sense. The only way to
find out about other app's windows is to have the user enable accessibility
in System Preferences. This has already been discussed in detail here and
on
other lists. You might try doing a search to see what's already been said.
In fact, this is no longer true on Leopard. Window are always in there own
space, but you can list all windows and even create image for each window
on
screen.
http://developer.apple.com/samplecode/SonOfGrab/
And it make sense to inlude other app window in an a list, else tools like
the GrabFS would not exists.

Problem with Memory Leaks
I've an image loaded into memory and I want to flip it. The problem is
that when I do it some memory is leaked. I've searched and sliced the
code but can't find where it is. Maybe someone can help. The function
I call is flip. If I call flip_v or needsDisplay only no leak
happens, but when both are called there is something wrong.
Thanks.

The call is done with click on a toolbar item, so it's not in a thread. With the copying and releasing m_image thing you are right. Your way is better. Thanks Btw.
