[Jython-users] A bit more progress (MacOS X)

[Deirdre S. M. <de...@de...>]

Based on some of the stuff that Steven Majewski did, trying to create 
a Cocoa app that loads a nib from Jython. When running, I get the 
following errors:

% jython CurrencyConverter.jy
(
     NSBundle </System/Library/Frameworks/Foundation.framework> (loaded),
     NSBundle </usr/lib> (loaded),
     NSBundle </System/Library/Frameworks/JavaVM.framework> (loaded),
     NSBundle </usr/lib/java> (loaded)
)
./build/CurrencyConverter2.app
May 11 21:35:32 java[1110] Unknown class `ConverterController' in nib 
file, using `NSObject' instead.
May 11 21:35:32 java[1110] Unknown class `Converter' in nib file, 
using `NSObject' instead.
May 11 21:35:32 java[1110] Could not connect the action convert: to 
target of class NSObject

So...why doesn't it know about the classes?


#!/usr/bin/env jython

class ConverterController(NSObject):

	def convert(sender):

		total = converter.convert(amount, rate);

		self.totalField.setFloatValue(total);
