Border

public interface Border
Interface describing an object capable of rendering a border around the edges of a swing component. For examples of using borders see How to Use Borders, a section in The Java Tutorial.

In the Swing component set, borders supercede Insets as the mechanism for creating a (decorated or plain) area around the edge of a component.

Usage Notes:

  • Use EmptyBorder to create a plain border (this mechanism replaces its predecessor, setInsets).
  • Use CompoundBorder to nest multiple border objects, creating a single, combined border.
  • Border instances are designed to be shared. Rather than creating a new border object using one of border classes, use the BorderFactory methods, which produces a shared instance of the common border types.
  • Additional border styles include BevelBorder, SoftBevelBorder, EtchedBorder, LineBorder, TitledBorder, and MatteBorder.
  • To create a new border class, subclass AbstractBorder.
