public class BasicSplitPaneDivider
extends Container
implements PropertyChangeListener, Serializable
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.
