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:
LayoutManager
on the component if necessary.
PropertyChangeListener
on the component in order
to detect and respond to component property changes appropriately.

. 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:
