A Metal L&F implementation of ScrollPaneUI.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running

of all JavaBeansTM
has been added to the java.beans package.

MetalScrollPaneUI
public MetalScrollPaneUI()
createUI
public static ComponentUI createUI(JComponent x)
installUI
public void installUI(JComponent c)
- Description copied from class:
ComponentUI
- Configures the specified component appropriate for the look and feel.
This method is invoked when the
ComponentUI instance is being installed
as the UI delegate on the specified component. This method should
completely configure the component for the look and feel,
including the following:
- Install any default property values for color, fonts, borders,
icons, opacity, etc. on the component. Whenever possible,
property values initialized by the client program should not
be overridden.
- Install a
LayoutManager on the component if necessary.
- Create/add any required sub-components to the component.
- Create/install event listeners on the component.
- Create/install a
PropertyChangeListener on the component in order
to detect and respond to component property changes appropriately.
- Install keyboard UI (mnemonics, traversal, etc.) on the component.
- Initialize any appropriate instance data.
- Overrides:
installUI in class BasicScrollPaneUI
- Parameters:
c - the component where this UI delegate is being installed- See Also:
ComponentUI.uninstallUI(javax.swing.JComponent) ,
JComponent.setUI(javax.swing.plaf.ComponentUI) ,
JComponent.updateUI()
uninstallUI
public void uninstallUI(JComponent c)
- Description copied from class:
ComponentUI
- Reverses configuration which was done on the specified component during
installUI . This method is invoked when this
UIComponent instance is being removed as the UI delegate
for the specified component. This method should undo the
configuration performed in installUI , being careful to
leave the JComponent instance in a clean state (no
extraneous listeners, look-and-feel-specific property objects, etc.).
This should include the following:
- Remove any UI-set borders from the component.
- Remove any UI-set layout managers on the component.
- Remove any UI-added sub-components from the component.
- Remove any UI-added event/property listeners from the component.
- Remove any UI-installed keyboard UI from the component.
- Nullify any allocated instance data objects to allow for GC.
- Overrides:
uninstallUI in class BasicScrollPaneUI
- Parameters:
c - the component from which this UI delegate is being removed;
this argument is often ignored,
but might be used if the UI object is stateless
and shared by multiple components- See Also:
ComponentUI.installUI(javax.swing.JComponent) ,
JComponent.updateUI()
installListeners
public void installListeners(JScrollPane scrollPane)
- Overrides:
installListeners in class BasicScrollPaneUI
uninstallListeners
public void uninstallListeners(JScrollPane scrollPane)
createScrollBarSwapListener
protected PropertyChangeListener createScrollBarSwapListener()
