Class BasicSplitPaneDivider.DragController
java.lang.Object
javax.swing.plaf.basic.BasicSplitPaneDivider.DragController
- Direct Known Subclasses:
- BasicSplitPaneDivider.VerticalDragController
- Enclosing class:
- BasicSplitPaneDivider
Handles the events during a dragging session for a
 HORIZONTAL_SPLIT oriented split pane. This continually
 messages 
dragDividerTo and then when done messages
 finishDraggingTo. When an instance is created it should be
 messaged with isValid to insure that dragging can happen
 (dragging won't be allowed if the two views can not be resized).
 
 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.
