Divider used by BasicSplitPaneUI. Subclassers may wish to override paint to do something more interesting. The border effect is drawn in BasicSplitPaneUI, so if you don't like that border, reset it there. To conditionally drag from certain areas subclass mousePressed and call super when you wish the dragging to begin.
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 JavaBeans

has been added to the java.beans package. Please see
