Change language during Runtime

Question

Hey,
i have following problem: I use Resourcebundles to internationalize my Java Applet. Now i want to add two Buttons where the user can change the language.
I changed my i18n class to the following code:
public class Messages
     private static final String          BUNDLE_NAME     = "de.mypackage.core.messages";     //$NON-NLS-1$
     private static ResourceBundle     resBundle     = null;
     static
          try
               resBundle = ResourceBundle.getBundle(BUNDLE_NAME);
          } catch (MissingResourceException exc)
               System.out.println("Can not find the ressource bundle for i18n.");
     static void setLocale(Locale locale)
          resBundle = ResourceBundle.getBundle(BUNDLE_NAME, locale);
     public static String getString(String key)
          try
               return resBundle.getString(key);
          } catch (MissingResourceException e)
               return '!' + key + '!';
}When pressing the "english" button following code is executed:
Messages.setLocale(Locale.ENGLISH);
applet.repaint();
applet.validate();But the language doesn�t change :-( What can i do?
Thanks alot

Answer 1

But the language doesn�t change :-( What can i do?I once did it this way: the problem is that all your Components already
had their text set (e.g. JButton.setText(...)) and all those components are
not aware of the fact that you changed your Locale so they don't do
anything.
Therefore I extended all these Swing classes and added an interface:
LanguageListener which gets invoked when a Locale has changed.
The Language listener just extends the PropertyChangeListener.
When the method is invoked the Component sets its text again according
to the now current Locale. It's a bit of work but it pays off ;-)
kind regards,
Jos
