Understanding the user interface and sample data
The application’s main user interface elements are:
a combo box for selecting a Locale
a combo box for selecting a Market
a DataGrid that displays data for six companies in each market
a chart that shows simulated historical data for the selected company’s stock
The application stores all of its sample data about locales, markets, and company stocks in the StockDataModel class.
A real application would retrieve data from a server and then store it in a class like StockDataModel. In this example,
all the data is hard coded in the StockDataModel class.
Note: The data displayed in the financial chart doesn’t necessarily match the data shown in the DataGrid control. The
chart is randomly redrawn each time a different company is selected. It is for illustration purposes only.
Setting the locale
After some initial setup work, the application calls the method Localizer.setLocale() to create formatter objects for the
default locale. The setLocale() method is also called each time the user selects a new value from the Locale combo box.
public function setLocale(newLocale:String):void
{
locale = new LocaleID(newLocale);
}
An ActionScript class that draws a chart of simulated stock data.
An ActionScript class that manages the locale and currency and handles the localized formatting of numbers,
currency amounts, and dates.
An ActionScript class that holds all the sample data for the Global Stock Ticker example.
nf = new NumberFormatter(locale.name);
traceError(nf.lastOperationStatus, "NumberFormatter", nf.actualLocaleIDName);
cf = new CurrencyFormatter(locale.name);
traceError(cf.lastOperationStatus, "CurrencyFormatter", cf.actualLocaleIDName);
symbolIsSafe = cf.formattingWithCurrencySymbolIsSafe(currentCurrency);
cf.setCurrency(currentCurrency, currentSymbol);
cf.fractionalDigits = currentFraction;
df = new DateTimeFormatter(locale.name, DateTimeStyle.LONG, DateTimeStyle.SHORT);
traceError(df.lastOperationStatus, "DateTimeFormatter", df.actualLocaleIDName);
monthNames = df.getMonthNames(DateTimeNameStyle.LONG_ABBREVIATION);
public function traceError(status:String, serviceName:String, localeID:String) :void
{
if(status != LastOperationStatus.NO_ERROR)
