Direct Known Subclasses:

MechanismTextField

public class DoubleTextField
extends javax.swing.Box
implements java.beans.PropertyChangeListener

A JComponent that consists of a JLabel on top of a JTextField. The text field is constrained to represent a double value. The value can be accessed via set/get methods. The name is final and can be accessed with Component.getName(). The value can be tied to a property of a JComponent (with key == name) or can be a property of this DoubleTextField itself, also with key == name. If it is tied to an outside property, that JComponent should be a PropertyChangeListener for itself, so that if this changes the value the source will know about it.

Constructor Detail

DoubleTextField

public DoubleTextField(java.lang.String name,
                       double value)

Creates a new instance of DoubleTextField with a given name and initial value, stored in this

Parameters:

name - the name

value - the value

Throws:

java.lang.NullPointerException - if name is null

DoubleTextField

public DoubleTextField(java.lang.String name,
                       javax.swing.JComponent source)

Creates a new instance of DoubleTextField with a given name, with the value stored in a JComponent

Parameters:

name - the name

source - the JComponent to use to store the value as a property. It should be a PropertyChangeListener for itself to catch when this changes the value. If source == null, use this to store the value

Throws:

java.lang.NullPointerException - if name is null or source does not have that property

java.lang.ClassCastException - if source's property is not a Number

DoubleTextField

public DoubleTextField(java.lang.String name,
                       double value,
