Class BasicSplitPaneDivider.VerticalDragController

Enclosing class:
BasicSplitPaneDivider
protected class BasicSplitPaneDivider.VerticalDragController
extends BasicSplitPaneDivider.DragController

Handles the events during a dragging session for a VERTICAL_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).
