Class DropShadowBorder

java.lang.Object
  org.jdesktop.swingx.border.DropShadowBorder

All Implemented Interfaces:

Serializable, Border

public class DropShadowBorder
extends Object
implements Border, Serializable

Implements a DropShadow for components. In general, the DropShadowBorder will work with any rectangular components that do not have a default border installed as part of the look and feel, or otherwise. For example, DropShadowBorder works wonderfully with JPanel, but horribly with JComboBox.

Note: DropShadowBorder should usually be added to non-opaque components, otherwise the background is likely to bleed through.

Note: Since generating drop shadows is relatively expensive operation, DropShadowBorder keeps internal static cache that allows sharing same border for multiple re-rendering and between different instances of the class. Since this cache is shared at class level and never reset, it might bleed your app memory in case you tend to create many different borders rapidly.
