All Implemented Interfaces:

FlatStylingSupport.StyleableBorder, java.io.Serializable, javax.swing.border.Border, javax.swing.plaf.UIResource

public class FlatDropShadowBorder
extends FlatEmptyBorder
implements FlatStylingSupport.StyleableBorder

Paints a drop shadow border around the component. Supports 1-sided, 2-side, 3-sided or 4-sided drop shadows.

The shadow insets allow specifying drop shadow thickness for each side. A zero or negative value hides the drop shadow on that side. A negative value can be used to indent the drop shadow on corners. E.g. -4 on left indents drop shadow at top-left and bottom-left corners by 4 pixels.
