|---|---|
protected JComponent |
createEditor()
This method is called by installUI to get the editor component
of the
JSpinner. |
protected LayoutManager |
createLayout()
Creates a
LayoutManager that manages the editor,
nextButton, and previousButton
children of the JSpinner. |
protected Component |
createNextButton()
Creates an increment button, i.e.
|
protected Component |
createPreviousButton()
Creates a decrement button, i.e.
|
static ComponentUI |
createUI(JComponent c)
Returns a new instance of SynthSpinnerUI.
|
SynthContext |
getContext(JComponent c)
Returns the Context for the specified component.
|
protected void |
installDefaults()
Initializes the
JSpinner border,
foreground, and background, properties
based on the corresponding "Spinner.*" properties from defaults table. |
protected void |
installListeners()
Initializes
PropertyChangeListener with
a shared object that delegates interesting PropertyChangeEvents
to protected methods. |
void |
paint(Graphics g,
JComponent c)
Paints the specified component according to the Look and Feel.
|
protected void |
paint(SynthContext context,
Graphics g)
Paints the specified component.
|
void |
paintBorder(SynthContext context,
Graphics g,
int x,
int y,
int w,
int h)
Paints the border.
|
void |
propertyChange(PropertyChangeEvent e)
This method gets called when a bound property is changed.
|
protected void |
replaceEditor(JComponent oldEditor,
JComponent newEditor)
Called by the
PropertyChangeListener when the
JSpinner editor property changes. |
protected void |
uninstallDefaults()
Sets the
JSpinner's layout manager to null. |
protected void |
uninstallListeners()
Removes the
PropertyChangeListener added
by installListeners. |
void |
update(Graphics g,
JComponent c)
Notifies this UI delegate to repaint the specified component.

PropertyChangeListener with

This method is called by installUI.

PropertyChangeListener added

This method is called by uninstallUI.

JSpinner border,

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.installDefaults in class BasicSpinnerUIuninstallDefaults(),

JSpinner's layout manager to null. This
method is called by uninstallUI.uninstallDefaults in class BasicSpinnerUIinstallDefaults(),
BasicSpinnerUI.uninstallUI(javax.swing.JComponent)protected LayoutManager createLayout()
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.createLayout in class BasicSpinnerUIBasicSpinnerUI.createNextButton(),
BasicSpinnerUI.createPreviousButton(),

spinner.getPreviousValue.
By default the previousButton is a JButton. If the
decrement button is not needed this method should return null.createPreviousButton in class BasicSpinnerUInullBasicSpinnerUI.installUI(javax.swing.JComponent),
BasicSpinnerUI.createNextButton(),
BasicSpinnerUI.installPreviousButtonListeners(java.awt.Component)protected Component createNextButton()
spinner.getNextValue.
By default the nextButton is a JButton. If the
increment button is not needed this method should return null.createNextButton in class BasicSpinnerUInullBasicSpinnerUI.installUI(javax.swing.JComponent),
BasicSpinnerUI.createPreviousButton(),
BasicSpinnerUI.installNextButtonListeners(java.awt.Component)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
overriden this method, then you'll probably want to override
replaceEditor as well.

replaceEditor(javax.swing.JComponent, javax.swing.JComponent),
JSpinner.getEditor()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 in class BasicSpinnerUIcreateEditor(),

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.

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