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.

    • paintBorder

      void paintBorder​(Component c, Graphics g, int x, int y, int width, int height)
      Paints the border for the specified component with the specified position and size.
      Parameters:
      c - the component for which this border is being painted
      g - the paint graphics
      x - the x position of the painted border
      y - the y position of the painted border
      width - the width of the painted border
      height - the height of the painted border

    • getBorderInsets

      Insets getBorderInsets​(Component c)
      Returns the insets of the border.
      Parameters:
      c - the component for which this border insets value applies
      Returns:
      an Insets object containing the insets from top, left, bottom and right of this Border

    • isBorderOpaque

      boolean isBorderOpaque()
      Returns whether or not the border is opaque. If the border is opaque, it is responsible for filling in it's own background when painting.
      Returns:
      true if this Border is opaque
