NumberField (fixed)

Numeric text field with automatic keystroke filtering and validation for integer (123) and decimal numbers (12.3).

Fixed version of the NumberField created by Markus Häcker.

It fixes the bug that manually added validators are ignored in the isValid() function which may lead to successful commits of invalid forms. See issue #3 (https://code.google.com/p/numberfield/issues/detail?id=3).

Sample code

NumberField numField = new NumberField();        // NumberField extends TextField
numField.setDecimalAllowed(true);                // not just integers (by default, decimals are allowed)
numField.setDecimalPrecision(2);                 // maximum 2 digits after the decimal separator
numField.setDecimalSeparator(',');               // e.g. 1,5
numField.setDecimalSeparatorAlwaysShown(true);   // e.g. 12345 -> 12345,
numField.setMinimumFractionDigits(2);            // e.g. 123,4 -> 123,40
numField.setGroupingUsed(true);                  // use grouping (e.g. 12345 -> 12.345)
numField.setGroupingSeparator('.');              // use '.' as grouping separator
numField.setGroupingSize(3);                     // 3 digits between grouping separators: 12.345.678
numField.setMinValue(0);                         // valid values must be >= 0 ...
numField.setMaxValue(999.9);                     // ... and <= 999.9
numField.setErrorText("Invalid number format!"); // feedback message on bad input
numField.setNegativeAllowed(false);              // prevent negative numbers (defaults to true)
numField.setValueIgnoreReadOnly("10");           // set the field's value, regardless whether it is read-only or not
numField.removeValidator();                      // omit server-side validation
