I am looking for a currency formatter for a double. I have tried to implement the example of an inner class demonstrated here
http://code.google.com/p/smartgwt/so...le.java?r=1547

But I could not sort out the inheritance issue or change the datasource which is double.

Is the SimpleTypeFormatter a better approach? Could you please point me to an example? Thank you.

I have also attempted to implement the following use of SimpleType to create a currency formatter for a datafield, but this has no effect on display or behavior....

final NumberFormat currencyFormat = NumberFormat.getCurrencyFormat();
SimpleType currencyType = new SimpleType("currency", FieldType.FLOAT);
currencyType.setNormalDisplayFormatter(new SimpleTypeFormatter() {
@Override
public String format(Object value, DataClass dataClass, DataBoundComponent dataBoundComponent, Record record) {
return ("$" + currencyFormat.format(Double.valueOf(String.valueOf(value.toString()))));
}
});
currencyType.setShortDisplayFormatter(new SimpleTypeFormatter() {
@Override
public String format(Object value, DataClass dataClass, DataBoundComponent dataBoundComponent, Record record) {
return ("$" + currencyFormat.format(Double.valueOf(String.valueOf(value.toString()))));
}
});
currencyType.setEditFormatter(new SimpleTypeFormatter() {
@Override
public String format(Object value, DataClass dataClass, DataBoundComponent dataBoundComponent, Record record) {
return ("$" + currencyFormat.format(Double.valueOf(String.valueOf(value.toString()))));
}
});
currencyType.setEditParser(new SimpleTypeParser() {
@Override
public Object parseInput(String s, DataClass dataClass, DataBoundComponent dataBoundComponent, Record record) {
return ("$" + currencyFormat.format(Double.valueOf(String.valueOf(s))));
}
});
currencyType.register();

------
DataSourceField productPrice = new DatSourceField();
productprice.setType("currencyType");

Any suggestions on using this properly would be appreciated.
