[Pyobjc-dev] NSUserDefaultsController

[Paul D. <pa...@do...>]

Hi,

I'm trying to use the new NSUserDefaultsController (part of Cocoa  
Bindings). I've got some example code in Obj-C (from  
http://homepage.mac.com/mmalc/CocoaExamples/controllers.html), but I'm  
having trouble converting it to PyObjC.

The original Obj-C code is:

	// Get font name and size from user defaults
	NSDictionary *values = [[NSUserDefaultsController  
sharedUserDefaultsController] values];
	NSString *fontName = [values valueForKey:@"FontName"];

So I've converted it to this:

		prefs =  
NSUserDefaultsController.sharedUserDefaultsController().values()
		print prefs
		print prefs['FontName']

Results in:

<_NSControllerObjectProxy: 0x1123830>
2004-04-13 00:12:22.453 Test[19056] An exception has occured:

     print prefs['FontName']
TypeError: unsubscriptable object

I'm not sure why the type of 'prefs' is an NSControllerObjectProxy. I  
was expecting it to be an NSDictionary* (and hence a python  
dictionary). I have an instance of an NSUserDefaultsController in my  
nib file, so I'm a bit stuck at this point.

I'm using pyobjc from anonymous CVS as of a couple of days ago, on  
10.3.3.

Cheers,

Paul
