  • Direct Known Subclasses:

    Enclosing class:
    JideSplitPaneDivider
    protected class JideSplitPaneDivider.DragController
extends java.lang.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).
