Class LayoutLockedFieldPanelCoordinator

All Implemented Interfaces:
ViewListener

public class LayoutLockedFieldPanelCoordinator extends LineLockedFieldPanelCoordinator
A LayoutLockedFieldPanelCoordinator is an extension of a LineLockedFieldPanelCoordinator that handles the fact that field panel layouts vary in size. It coordinates the scrolling of a set of field panels by sharing bound scroll models that are locked together by a set of index numbers for the FieldPanel Layouts. All the field panels are locked together at the index numbers specified in the locked line array. In other words this coordinator tries to keep the layout indicated by the line (or index) for each field panel side by side with the indicated layout for each other field panel.
Note: The layouts that are locked together will be positioned so that the bottom of those layouts line up within the field panels.
