Hello,

IMHO the only option you have is to render the GUI again. I did not do 
this in practice, though. The way swixml handles the locale issue is to 
respect the locale coming from the system at program startup. This is 
fine and IMHO fits the normal usage of a program. Sure it is a cool 
thing to change the locale in your program and everything (dates, 
numbers, scrollbars, ...) will suddenly change. But this is not a 
customer cares for... Correct me if I'm wrong...

There is no inheritance in respect to the locale. The way I would solve 
this requires adding a property change listener to your root component. 
This has to be a subclass of JComponent (which it usually is) so you 
have the method addPropertyChangeSupport(String, PropertyChangeListener)
This method you call with the string "Locale" and a 
PropertyChangeListener which does in its propertyChange method the 
following: Foreach component of rootComponent.getComponents() set the 
locale according to the one the user selected. If the component you set 
the locale for happens to be a container as well, iterate through its 
subcomponents as well.
