• installListeners

  protected void installListeners()

  Description copied from class: BasicSpinnerUI
  Initializes PropertyChangeListener with a shared object that delegates interesting PropertyChangeEvents to protected methods.

  This method is called by installUI.

  Overrides:

  installListeners in class BasicSpinnerUI

  See Also:

  BasicSpinnerUI.replaceEditor(javax.swing.JComponent, javax.swing.JComponent), BasicSpinnerUI.uninstallListeners()

• uninstallListeners

  protected void uninstallListeners()

  Description copied from class: BasicSpinnerUI
  Removes the PropertyChangeListener added by installListeners.

  This method is called by uninstallUI.

  Overrides:

  uninstallListeners in class BasicSpinnerUI

  See Also:

  BasicSpinnerUI.installListeners()

• installDefaults

  protected void installDefaults()

  Initializes 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.

  Overrides:

  installDefaults in class BasicSpinnerUI

  See Also:

  uninstallDefaults(), BasicSpinnerUI.installUI(javax.swing.JComponent), createLayout(), LookAndFeel.installBorder(javax.swing.JComponent, java.lang.String), LookAndFeel.installColors(javax.swing.JComponent, java.lang.String, java.lang.String)

• uninstallDefaults

  protected void uninstallDefaults()

  Sets the JSpinner's layout manager to null. This method is called by uninstallUI.

  Overrides:

  uninstallDefaults in class BasicSpinnerUI

  See Also:

  installDefaults(), BasicSpinnerUI.uninstallUI(javax.swing.JComponent)

• createLayout

  protected LayoutManager createLayout()

  Description copied from class: BasicSpinnerUI
  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.

  Overrides:

  createLayout in class BasicSpinnerUI

  Returns:

  a LayoutManager for the editor, next button, and previous button.

  See Also:

  BasicSpinnerUI.createNextButton(), BasicSpinnerUI.createPreviousButton(), BasicSpinnerUI.createEditor()

• createPreviousButton

  protected Component createPreviousButton()

  Description copied from class: BasicSpinnerUI
  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 JButton. If the decrement button is not needed this method should return null.

  Overrides:

  createPreviousButton in class BasicSpinnerUI

  Returns:

  a component that will replace the spinner's value with the previous value in the sequence, or null

  See Also:

  BasicSpinnerUI.installUI(javax.swing.JComponent), BasicSpinnerUI.createNextButton(), BasicSpinnerUI.installPreviousButtonListeners(java.awt.Component)

• createNextButton

  protected Component createNextButton()

  Description copied from class: BasicSpinnerUI
  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 JButton. If the increment button is not needed this method should return null.

  Overrides:

  createNextButton in class BasicSpinnerUI

  Returns:

  a component that will replace the spinner's value with the next value in the sequence, or null

  See Also:

  BasicSpinnerUI.installUI(javax.swing.JComponent), BasicSpinnerUI.createPreviousButton(), BasicSpinnerUI.installNextButtonListeners(java.awt.Component)

• createEditor

  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.

  Overrides:

  createEditor in class BasicSpinnerUI

  Returns:

  the JSpinners editor JComponent, spinner.getEditor() by default

  See Also:

  BasicSpinnerUI.installUI(javax.swing.JComponent), replaceEditor(javax.swing.JComponent, javax.swing.JComponent), JSpinner.getEditor()

• replaceEditor

  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.remove(oldEditor);
   spinner.add(newEditor, "Editor");
   

  The implementation of replaceEditor should be coordinated with the createEditor method.

  Overrides:

  replaceEditor in class BasicSpinnerUI

  See Also:

  createEditor(), BasicSpinnerUI.createPropertyChangeListener()

• getContext

  public SynthContext getContext(JComponent c)

  Description copied from interface: SynthUI
  Returns the Context for the specified component.

  Specified by:

  getContext in interface SynthUI

  Parameters:

  c - Component requesting SynthContext.

  Returns:

  SynthContext describing component.

• update

  public void update(Graphics g,
            JComponent c)

  Notifies this UI delegate to repaint the specified component. This method paints the component background, then calls the paint(SynthContext,Graphics) method.

  In general, this method does not need to be overridden by subclasses. All Look and Feel rendering code should reside in the paint method.

  Overrides:

  update in class ComponentUI

  Parameters:

  g - the Graphics object used for painting

  c - the component being painted

  See Also:

  paint(SynthContext,Graphics)

• paint

  public void paint(Graphics g,
           JComponent c)

  Paints the specified component according to the Look and Feel.

  This method is not used by Synth Look and Feel. Painting is handled by the paint(SynthContext,Graphics) method.

  Overrides:

  paint in class ComponentUI

  Parameters:

  g - the Graphics object used for painting

  c - the component being painted

  See Also:

  paint(SynthContext,Graphics)

• paint

  protected void paint(SynthContext context,
           Graphics g)

  Paints the specified component. This implementation does nothing.

  Parameters:

  context - context for the component being painted

  g - the Graphics object used for painting

  See Also:

  update(Graphics,JComponent)

• paintBorder

  public void paintBorder(SynthContext context,
                 Graphics g,
                 int x,
                 int y,
                 int w,
                 int h)

  Description copied from interface: SynthUI
  Paints the border.

  Specified by:

  paintBorder in interface SynthUI

  Parameters:

  context - a component context

  g - Graphics to paint on

  x - the X coordinate

  y - the Y coordinate

  w - width of the border

  h - height of the border

• propertyChange

  public void propertyChange(PropertyChangeEvent e)

  Description copied from interface: PropertyChangeListener
  This method gets called when a bound property is changed.

  Specified by:

  propertyChange in interface PropertyChangeListener

  Parameters:

  e - A PropertyChangeEvent object describing the event source and the property that has changed.
