Class VertexLabelAsShapeRenderer<V,E>

java.lang.Object

edu.uci.ics.jung.visualization.renderers.VertexLabelAsShapeRenderer<V,E>

Type Parameters:

V - the vertex type

V - the edge type

All Implemented Interfaces:

com.google.common.base.Function<V,Shape>, Renderer.VertexLabel<V,E>

public class VertexLabelAsShapeRenderer<V,E>
extends Object
implements Renderer.VertexLabel<V,E>, com.google.common.base.Function<V,Shape>

Renders Vertex Labels, but can also supply Shapes for vertices. This has the effect of making the vertex label the actual vertex shape. The user will probably want to center the vertex label on the vertex location.

Method Detail

prepareRenderer

public Component prepareRenderer(RenderContext<V,E> rc,
                                 VertexLabelRenderer graphLabelRenderer,
                                 Object value,
                                 boolean isSelected,
                                 V vertex)

labelVertex

public void labelVertex(RenderContext<V,E> rc,
                        Layout<V,E> layout,
                        V v,
                        String label)

Labels the specified vertex with the specified label. Uses the font specified by this instance's VertexFontFunction. (If the font is unspecified, the existing font for the graphics context is used.) If vertex label centering is active, the label is centered on the position of the vertex; otherwise the label is offset slightly.
