public class NumberField
extends TextField<java.lang.Number>

Numeric text field that provides automatic keystroke filtering and numeric validation.

When the field wraps any thing other than Double, either setPropertyEditorType(Class) or Field.setPropertyEditor(PropertyEditor) should be called with the appropriate number type.

 NumberField<Integer> field = new NumberField<Integer>;
 field.setPropertyEdtiorType(Integer.class);
