If I detach an NSThread will Cocoa run it in a separate memory heap or memory zone? For example, if I were to detach a thread, use malloc to create a large buffer, and then let the thread exit, would I get that memory back in some kind of automatic thread cleanup, or would it be leaked? What about if I used a POSIX thread (pthread) inst...

Is there any equivalent function on OS X to SetTimer in Windows? I'm using C++. So I'm writing a plugin for some software, and I need to have a funtion called periodically.

If you create a status bar app with no windows, how do you respond to events? My first guess was creating an subclass of NSResponder and override the appropriate methods. However they never get called. This lead explicitly calling: [self becomeFirstResponder]; Which also didn't work (and I don't believe is recommended by the Apple D...
I have an NSArray of strings and I want to add a certain amount of rows to the outline view depending on how many strings are in the array, each with the title of the String that was added.

Kind of a weird newbie question...I want to use typedef enum declarations in one of my classes . This particular class gets used by other classes, where a client class might say something like "set your style to Style1 (enumerated type)". Then the target class's behavior would change accordingly. This is analogous to the way that UITa...
I'm trying to figure out how to update an NSTextField programatically. I've figured out how to get the current value of the Text Field from Python: myVar = objc.IBOutlet() .... self.myVar.stringValue() How do I set the value of myVar from the Python side and have the GUI update? I'd like some sort of two way binding (like {myVAR} in...
Hey All, I'm completely stumped with this problem. I made a custom search control that uses a few different classes. For some reason, when an NSTextField is anywhere over these different pieces, it displays a solid black border around it, and the cursor doesn't blink. If anyone has a couple minutes - I've put together my code on pasteb...
I'm going through a tutorial on drawing a custom [shaped] window with cocoa by subclassing NSWindow. The tutorial states that in initializer developer should do the following: [self setOpaque:NO]; [self setBackgroundColor:[NSColor clearColor]]; So i'm wondering what is the differnce between these two messages and why are they needed ...

I create a custom borderless window and override it's setContentView / contentView accessors. This seems to work fine and custom contentView's in...

I'm using Distributed Objects in my application to provide communication between a tiny authentication agent program and the main application. The main application spawns NSTask's, which in turn will invoke the authentication program, which in turn will call back to the main program to get some user credentials. I know it sounds convol...
Right now I have my application executing some things using AuthorizationExecuteWithPrivileges. The problem is that it needs to ask for the password for every operation. Is there any way I could have it authenticate as soon as the app starts so that it won't ask for authorization later, and then release the authorization object when its ...
