public void installUI(JComponent c)
ComponentUIComponentUI 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.

public void uninstallUI(JComponent c)
ComponentUIinstallUI. 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:
uninstallUI in class ComponentUIc - 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 componentsComponentUI.installUI(javax.swing.JComponent),

this method and use the specified Graphics object to

(this is the preferred approach for any component with a specific
layout manager installed). The default implementation of this
