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 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. Please see XMLEncoder
