Re: i18n with swixml

Hello

This is my first contribution tu this mailing liste but i would like to give 
my opinion on your remark Frank.

I use swixml for a while now and I am very happy with it.

But about internationalization, you should know that many countries like 
Belgium, EAU and others use more than one signle language and are happy to 
switch from one to the other in a single click.

This is really a major point in a product competition in those countries.

So. please, do not be so strict on the use of the Locale. This set of 
Classes are very importante.

Regards
patt

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.
