public interface LinesManager<A extends Activity>
A lines manager is used to control the layout of lines inside a row. Activities located on different lines do not overlap each other, except if the lines themselves overlap each other. Each line can have its own height and a location within the row. Each line can also have its own Layout . By using lines and layouts it is possible to display activities that belong to the same row in different ways (see ChartLayout, AgendaLayout, GanttLayout).
