Constructor Detail

MetalScrollPaneUI

public MetalScrollPaneUI()

Constructs a new instance of MetalScrollPaneUI.

Method Detail

createScrollBarSwapListener

protected PropertyChangeListener createScrollBarSwapListener()

TODO

createUI

public static ComponentUI createUI(JComponent component)

Returns a shared instance of MetalScrollPaneUI.

Parameters: component the component for which we return an UI instance

Returns: A shared instance of MetalScrollPaneUI.

installListeners

public void installListeners(JScrollPane scrollPane)

Installs listeners on scrollPane

Parameters: scrollPane - the component to install the listeners on

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: 1. 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. 2. Install a LayoutManager on the component if necessary. 3. Create/add any required sub-components to the component. 4. Create/install event listeners on the component. 5. Create/install a PropertyChangeListener on the component in order to detect and respond to component property changes appropriately. 6. Install keyboard UI (mnemonics, traversal, etc.) on the component. 7. Initialize any appropriate instance data.

Parameters: c - the component to install the ui on

uninstallListeners

public void uninstallListeners(JScrollPane scrollPane)

Uninstalls listeners on scrollPane

Parameters: scrollPane - the component to uninstall the listeners on

uninstallUI

public void uninstallUI(JComponent c)

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: 1. Remove any UI-set borders from the component. 2. Remove any UI-set layout managers on the component. 3. Remove any UI-added sub-components from the component. 4. Remove any UI-added event/property listeners from the component. 5. Remove any UI-installed keyboard UI from the component. 6. Nullify any allocated instance data objects to allow for GC.

Parameters: c - the component to uninstall the ui on
