Interface IlvGanttGridContext

public interface IlvGanttGridContext

This interface defines a render context for painting Gantt grids. The interface provides the necessary information needed to paint the horizontal and the vertical grids of the Gantt sheet. This interface is used by IlvGanttGridRenderer implementations to make them independent of the Gantt sheet and allows them to render in both screen and printer contexts.
