Class ArrowIcon

com.sas.swing.visuals.ArrowIcon

All Implemented Interfaces:

javax.swing.Icon

public class ArrowIcon
implements javax.swing.Icon

ArrowIcon is used by the SpinButton to paint the up/down arrows on the buttons. ArrowIcon implements Icon so it can be used on any AbstractButton. The constructor for the ArrowIcon can take a direction that the arrow is supposed to be painted in, using the SwingConstants NORTH, SOUTH, WEST, and EAST as valid values. Also, you can set whether the arrow should be painted pressed (just translates the arrow down and to the right 1 pixel). This functionality is added as a convenience to the user if they want a more visual appearance of the button being pressed. The default direction the Arrow faces is down (south).
