InstallOSLocale

So, I was working on making the mozilla internals in galeon match the
locale.  I called this code fragment from mozilla_embed_class_init. 

I've already sent this to Chris Blizzard.  I hope it'll be included
directly in a future version of gtkmozembed, but I thought I'd send it
to you guys anyway.

Thanks,
   Chris


#include <chrome/nsIChromeRegistry.h>
#include <locale/nsILocaleService.h>

static nsresult
getUILang(nsAString& aUILang)
{
	nsresult       result;
	// get a locale service
	nsCOMPtr<nsILocaleService> localeService = do_GetService(NS_LOCALESERVICE_CONTRACTID, &result);
	NS_ASSERTION(NS_SUCCEEDED(result),"getUILang: get locale service failed");

	nsXPIDLString uiLang;
	result = localeService->GetLocaleComponentForUserAgent(getter_Copies(uiLang));
	aUILang = uiLang;
	return result;
}
 
// update global locale if possible (in case when user-*.rdf can be updated)
// so that any apps after this can be invoked in the UILocale and contentLocale
static nsresult InstallOSLocale(void)
{
	nsresult rv = NS_OK;
	nsAutoString uiLang;
	// compute lang code
	rv = getUILang(uiLang);

	nsCOMPtr<nsIXULChromeRegistry> chromeRegistry = do_GetService(NS_CHROMEREGISTRY_CONTRACTID, &rv);
	if (chromeRegistry) {
		chromeRegistry->SetRuntimeProvider(PR_TRUE);
		rv = chromeRegistry->SelectLocale(NS_ConvertUCS2toUTF8(uiLang), PR_FALSE);
	}

	return NS_OK;
}
