MatteBorderpublic class MatteBorder extends EmptyBorder | A class which provides a matte-like border of either a solid color
or a tiled icon.
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.

|---|
| protected Color | color | | protected Icon | tileIcon |
| Constructors Summary |

public MatteBorder(int top, int left, int bottom, int right, Color matteColor)Creates a matte border with the specified insets and color.
super(top, left, bottom, right);
this.color = matteColor;
| public MatteBorder(Insets borderInsets, Color matteColor)Creates a matte border with the specified insets and color.
super(borderInsets);
this.color = matteColor;
| public MatteBorder(int top, int left, int bottom, int right, Icon tileIcon)Creates a matte border with the specified insets and tile icon.
super(top, left, bottom, right);
this.tileIcon = tileIcon;
| public MatteBorder(Insets borderInsets, Icon tileIcon)Creates a matte border with the specified insets and tile icon.
super(borderInsets);
this.tileIcon = tileIcon;
| public MatteBorder(Icon tileIcon)Creates a matte border with the specified tile icon. The
insets will be calculated dynamically based on the size of
the tile icon, where the top and bottom will be equal to the
tile icon's height, and the left and right will be equal to
the tile icon's width.
