public class DefaultGraphEdgeRenderer

Object
DefaultGraphEdgeRenderer

Paints an edge as a line with an arrowhead on a directed edge and its label in a pill at the middle.

Colours come from NodeGraphEdge (the line) and NodeGraphEdgeLabel (the pill and its text); a selected edge takes the colour of NodeGraphNodeSelected. An edge’s style key picks a colour from setColor.
