JSpinners layout is set to the value returned by
createLayout. This method is called by

protected LayoutManagercreateLayout()
LayoutManager that manages the
editor,
nextButton, and
previousButton children of the JSpinner. These three children must be added with a constraint that identifies their role: "Editor", "Next", and "Previous". The default layout manager can handle the absence of any of these children.

spinner.getPreviousValue. By default the
previousButton is a
JButton. If the decrement button is not needed this method should return
null.

protected JComponentcreateEditor()
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 overriden this method, then you'll probably want to override replaceEditor as well.

protected void replaceEditor(JComponentoldEditor, 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.
