## javax.swing.border
Interface Border

All Known Implementing Classes:
  AbstractBorder, BasicBorders.SplitPaneBorder, BorderUIResource

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.

  `BorderFactory`, `EmptyBorder`, `CompoundBorder`

Method Summary
`Insets` | `getBorderInsets(Component c)` Returns the insets of the border.
`boolean` | `isBorderOpaque()` Returns whether or not the border is opaque.
`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.

Method Detail

### paintBorder

    public 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

    public Insets getBorderInsets(Component c)

  Returns the insets of the border.

  Parameters:
    `c` - the component for which this border insets value applies

### isBorderOpaque

    public 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.
