javax.swing.plaf.basic
Class BasicSplitPaneDivider.DragController

java.lang.Object
  extended by 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 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 JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.
