Class LineLockedFieldPanelCoordinator

  • All Implemented Interfaces:
    ViewListener
    Direct Known Subclasses:
    DualDecompilerFieldPanelCoordinator, LayoutLockedFieldPanelCoordinator
    public class LineLockedFieldPanelCoordinator
extends FieldPanelCoordinator
    A LineLockedFieldPanelCoordinator coordinates the scrolling of a set of field panels by sharing bound scroll models that are locked together by a set of line numbers. All the field panels are locked together at the line numbers specified in the locked line array. In other words this coordinator tries to keep the indicated line for each field panel side by side with the indicated line for each other field panel.
