public static class JSpinner.DefaultEditor extends JPanel implements ChangeListener, PropertyChangeListener, LayoutManager
JFormattedTextField. Subclasses
can configure the JFormattedTextField to create
an editor that's appropriate for the type of model they
support and they may want to override
the stateChanged and propertyChanged
methods, which keep the model and the text field in sync.
This class defines a dismiss method that removes the
editors ChangeListener from the JSpinner
that it's part of. The setEditor method knows about
DefaultEditor.dismiss, so if the developer
replaces an editor that's derived from JSpinner.DefaultEditor
its ChangeListener connection back to the
JSpinner will be removed. However after that,
it's up to the developer to manage their editor listeners.
Similarly, if a subclass overrides createEditor,
it's up to the subclasser to deal with their editor
subsequently being replaced (with setEditor).
We expect that in most cases, and in editor installed
with setEditor or created by a createEditor
override, will not be replaced anyway.
This class is the LayoutManager for it's single
JFormattedTextField child. By default the
child is just centered with the parents insets.

JSpinner.
This DefaultEditor is it's own layout manager and
it is added to the spinner's ChangeListener list.
The constructor creates a single JFormattedTextField child,
initializes it's value to be the spinner model's current value
and adds it to this DefaultEditor.spinner - the spinner whose model this editor will monitorgetTextField(),

JSpinner. By default, this method removes
itself from the spinners ChangeListener list.spinner - the JSpinner to disconnect this
editor from; the same spinner as was passed to the constructor.public JSpinner getSpinner()
JSpinner ancestor of this editor or
null if none of the ancestors are a
JSpinner.
Typically the editor's parent is a JSpinner however
subclasses of JSpinner may override the
the createEditor method and insert one or more containers
between the JSpinner and it's editor.JSpinner ancestor; null
if none of the ancestors are a JSpinnerJSpinner.createEditor(javax.swing.SpinnerModel)public JFormattedTextField getTextField()

editor. By default the text field is the first and only

PropertyChangeListener. When the "value"
property changes, which implies that the user has typed a new
number, we set the value of the spinners model.
This class ignores PropertyChangeEvents whose
source is not the JFormattedTextField, so subclasses
may safely make this DefaultEditor a
PropertyChangeListener on other objects.
