public class BasicArrowButton
JButton object that draws a scaled Arrow in one of the cardinal directions.
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
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeansTM
has been added to the java.beans package.

JComponentpaint directly,
but should instead use the repaint method to
schedule the component for redrawing.
This method actually delegates the work of painting to three
protected methods: paintComponent,
paintBorder,
and paintChildren. They're called in the order
listed to ensure that children appear on top of component itself.
Generally speaking, the component and its children should not
paint in the insets area allocated to the border. Subclasses can
just override this method, as always. A subclass that just
wants to specialize the UI (look and feel) delegate's
paint method should just override
paintComponent.

BasicArrowButtons are used as a child component of
composite components such as JScrollBar and
JComboBox. Since the composite component typically gets the
focus, this method is overriden to return false.
