Class AbstractVisualGraphComponent

java.lang.Object

salvo.jesus.graph.visual.AbstractVisualGraphComponent

All Implemented Interfaces:

Serializable, VisualGraphComponent

Direct Known Subclasses:

VisualEdge, VisualVertex

public abstract class AbstractVisualGraphComponent
extends Object
implements VisualGraphComponent

This abstract class is meant to encapsulate a GraphComponent, either a Verte or an Edge, and define visual attributes for that component for use in a GraphPanel.

These attributes include:

• GeneralPath used to draw
• Font used to draw the string label
• Outline color and the background color
• Outline color and the background color
• Painter responsible for painting the GraphComponent
• VisualGraphs where the VisualGraphComponent is drawn
• MouseListeners and MouseMotionListners for mouse events on the VisualGraphComponent.
