public class NumberField
extends ResizableTextField

Descendant of ResizableTextField which only allows input of numbers. Double and long number formats are supported through number document classes DobuleDocument and LongDocument, both descedents of AbstractNumberDocument, while display format is controlled using com.cosylab.util.PrintfFormat string parser. The number field operates in two modes. When in focus mode, the user can type in numbers that are recognized by the set number document of the number field. When the user presses the Enter key or the component goes out of focus the typed value is checked for range using the set minimum and maximum allowed values. Than the new value is displayed using the com.cosylab.util.PrinfFormat with the set format string. Value stored by the number field can be accessed through getter and setter methods in both double or long or even generic Number type.
