Class NumberFormatFieldFactory

java.lang.Object

repicea.gui.components.NumberFormatFieldFactory

public class NumberFormatFieldFactory
extends java.lang.Object

The NumberFormatFieldFactory class provides JTextField instances specially designed to receive numbers. The Document instance in the JTextField does not update if the inserted text does not comply with the rules set in the nested class NumberFormatter. Whenever, the text is changed successfully, the Document instance within the JTextField fires a NumberFieldDocumentEvent instance. The event can be listened to by adding a NumberFieldListener to the JFormattedNumericField instance.
