This addon is a modification of TextField, which accepts only number input and has new properties.

1. Enable/disable negative values #setSigned. Default true.
2. Enable/disable number grouping #setUseGrouping. Default false.
3. Setting grouping separator #setGroupingSeparator. Default character dot character.
4. Enable/disable decimal numbers #setDecimal. Default false.
5. Setting decimal separator #setDecimalSeparator. Default value space character.

If you want to get converted value, you need to use binder and set custom converter by calling binderBuilder.forField(field) .withConverter(createStringToIntegerConverter())

For demo you could checkout and run demo app from here.

Sample code

    public NumberField createInstance() {
        NumberField field = new NumberField("Amount");
        field.setSigned(false);                                                 // disable negative sign, default true
        field.setUseGrouping(true);                                        // enable grouping, default false
        field.setGroupingSeparator(' ');                                  // set grouping separator ' '
        field.setDecimal(true);                                               // enables input of decimal numbers, default false
        field.setDecimalSeparator('.');                                   // set decimal separator, default '.'
        field.setConverter(converter);                                   // custom converter
        return field;
    }
