protected JComponent createEditor()
JSpinner
. By default it just returns JSpinner.getEditor()
. Subclasses can override createEditor
to return a component that contains the spinner's editor or null, if they're going to handle adding the editor to the JSpinner
in an installUI
override. Typically this method would be overridden to wrap the editor with a container with a custom border, since one can't assume that the editors border can be set directly.
The replaceEditor
method is called when the spinners editor is changed with JSpinner.setEditor
. If you've overridden this method, then you'll probably want to override replaceEditor
as well.

protected void replaceEditor(JComponent oldEditor, JComponent newEditor)
PropertyChangeListener
when the JSpinner
editor property changes. It's the responsibility of this method to remove the old editor and add the new one. By default this operation is just: spinner.remove(oldEditor); spinner.add(newEditor, "Editor");The implementation of
replaceEditor
should be coordinated with the createEditor
method.replaceEditor

method.
