All Implemented Interfaces:

Direct Known Subclasses:

DefaultChartLayout

public class LegendComponentLayout

extends Object

implements LayoutManager, Serializable

A layout manager that implements a default layout for large JClass components, such as JClass Chart and JClass Gauge, that comprise a drawing area, a header, a footer, and a legend (a JCLegend object). This layout places the drawing area class in the leftover space after the legend, the header and the footer have been layed out, unless specific layout hints were set on the object in JCChart. Any component using this layout manager must implement LegendComponentLayoutUser.
