Question

I try to get all date/time format pattern in GWT, using DateTimeFormat.PredefinedFormat to get all pattern of the current locale. but how can i get all pattern for an other locale.

Answer 1

I found a way, not the generic way what i want, but in this case it works. Perhaps has someone a better solution.

   private static Date testDateFormates( String dateText ) {

        ArrayList<String> locales = new ArrayList<String>();

        DateTimeFormatInfo formatDE = new DateTimeFormatInfoImpl_de();
        DateTimeFormatInfo formatEN = new DateTimeFormatInfoImpl_en();
        DateTimeFormatInfo formatFR = new DateTimeFormatInfoImpl_fr();
        DateTimeFormatInfo formatES = new DateTimeFormatInfoImpl_es();
        DateTimeFormatInfo formatZH = new DateTimeFormatInfoImpl_zh();
        DateTimeFormatInfo formatRU = new DateTimeFormatInfoImpl_ru();

        addToList( locales, LocaleInfo.getCurrentLocale().getDateTimeFormatInfo() );
        addToList( locales, formatDE );
        addToList( locales, formatEN );
        addToList( locales, formatFR );
        addToList( locales, formatES );
        addToList( locales, formatZH );
        addToList( locales, formatRU );

        .
        .
        .  
    }

    private static void addToList( ArrayList<String> patterns, DateTimeFormatInfo format ) {
        patterns.add( format.dateFormat() );
        patterns.add( format.dateFormatFull() );
        patterns.add( format.dateFormatLong() );
        patterns.add( format.dateFormatMedium() );
        patterns.add( format.dateFormatShort() );
    }
