Hi there,
I’ve some problems using the ResourceBundle and nifty gui.
I included the resourceBundle-tag ([xml]<resourceBundle id="" filename="" />[/xml]) into my nifty-xml-file, but I cannot change the ResourceBundle-Content at runtime.
Actually I did not find out whats behind the usage of ResourceBundle in the nifty class. The field resourceBundleSource in the class Nifty seems not to be used at all. There is a setLocale and a addResourceBundle method, please what ?
Maybe someone has any experience with that and can help me 
It should be covered in:
http://freefr.dl.sourceforge.net/project/nifty-gui/nifty-gui/nifty-gui-the-manual-v1.0.pdf
Thanks for the hint but the manual was no help.
My modest solution looks as follows:
[java]@NiftyEventSubscriber(id="language_selection")
public void onRadioGroup1Changed(final String id, final RadioButtonGroupStateChangedEvent event) {
nifty.setLocale(new Locale(event.getSelectedId()));
nifty.addResourceBundle("lang", "Interface/languages/lang");
for (String screenID : nifty.getAllScreensName()) {
Screen screen = nifty.getScreen(screenID);
updateTextElements(screen.getRootElement(), "lang");
screen.layoutLayers();
}
}[/java]
I set a new locale and resource bundle to the nifty instance.
The id of the selected button is the corresponding locale.
Unfortunately I found no other possibility than going through all elements and setting the corresponding bundle command after setting the new bundle.
[java]private void updateTextElements(Element element, String bundleSelector) {
if (element == null)
return;
String id = element.getId();
TextRenderer renderer = element.getRenderer(TextRenderer.class);
// all text elements we want to be changed start with the § symbol followed by the resource bundle key
if (id != null && id.startsWith("§") && renderer != null) {
renderer.setText("${" + bundleSelector + "." + id.substring(1, id.length()) + "}");
}
// update all child elements
for (Element child : element.getElements()) {
updateTextElements(child, bundleSelector);
}
}[/java]
