Method from javax.swing.plaf.basic.BasicSpinnerUI Detail:
 protected JComponent createEditor() 
    This method is called by installUI to get the editor component of the 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 LayoutManager createLayout() 
    Creates a 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.
 protected Component createNextButton() 
    Creates an increment button, i.e. component that replaces the spinner value with the object returned by spinner.getNextValue. By default the nextButton is a {@code JButton}. If the increment button is not needed this method should return {@code null}.
 protected Component createPreviousButton() 
    Creates a decrement button, i.e. component that replaces the spinner value with the object returned by spinner.getPreviousValue. By default the previousButton is a {@code JButton}. If the decrement button is not needed this method should return {@code null}.
 protected PropertyChangeListener createPropertyChangeListener() 
    Creates a PropertyChangeListener that can be added to the JSpinner itself. Typically, this listener will call replaceEditor when the "editor" property changes, since it's the SpinnerUI's responsibility to add the editor to the JSpinner (and remove the old one). This method is called by installListeners.
 public static ComponentUI createUI(JComponent c) 
    Returns a new instance of BasicSpinnerUI. SpinnerListUI delegates are allocated one per JSpinner.
 public int getBaseline(JComponent c,
    int width,
    int height) 
    Returns the baseline.
 public BaselineResizeBehavior getBaselineResizeBehavior(JComponent c) 
    Returns an enum indicating how the baseline of the component changes as the size changes.
 protected  void installDefaults() 
    Initialize the JSpinner border, foreground, and background, properties based on the corresponding "Spinner.*" properties from defaults table. The JSpinners layout is set to the value returned by createLayout. This method is called by installUI.
 protected  void installKeyboardActions() 
    Installs the keyboard Actions onto the JSpinner.
 protected  void installListeners() 
    Initializes PropertyChangeListener with a shared object that delegates interesting PropertyChangeEvents to protected methods.

    This method is called by installUI.

 protected  void installNextButtonListeners(Component c) 
    Installs the necessary listeners on the next button, c, to update the JSpinner in response to a user gesture.
 protected  void installPreviousButtonListeners(Component c) 
    Installs the necessary listeners on the previous button, c, to update the JSpinner in response to a user gesture.
 public  void installUI(JComponent c) 
    Calls installDefaults, installListeners, and then adds the components returned by createNextButton, createPreviousButton, and createEditor.
 static  void loadActionMap(LazyActionMap map) 
 protected  void replaceEditor(JComponent oldEditor,
    JComponent newEditor) 
    Called by the 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.add(newEditor, "Editor");
    The implementation of replaceEditor should be coordinated with the createEditor method.
 protected  void uninstallDefaults() 
    Sets the JSpinner's layout manager to null. This method is called by uninstallUI.
 protected  void uninstallListeners() 
    Removes the PropertyChangeListener added by installListeners.

    This method is called by uninstallUI.

 public  void uninstallUI(JComponent c) 
    Calls uninstallDefaults, uninstallListeners, and then removes all of the spinners children.
