Class BasicSplitPaneDivider.DragController
java.lang.Object | +--javax.swing.plaf.basic.BasicSplitPaneDivider.DragController
- Direct Known Subclasses:
- BasicSplitPaneDivider.VerticalDragController
- Enclosing class:
- BasicSplitPaneDivider
- protected class BasicSplitPaneDivider.DragController
- extends Object
Handles the events during a dragging session for a HORIZONTAL_SPLIT orientated 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. A future release of Swing will provide support for long term persistence.
