Class DefaultGraphNodeRenderer

java.lang.Object

com.codename1.ui.graph.DefaultGraphNodeRenderer

All Implemented Interfaces:

GraphNodeRenderer

public class DefaultGraphNodeRenderer
extends Object
implements GraphNodeRenderer

Paints a node as a rounded card: a coloured strip on the leading edge, the label, the description under it, and the ports on the sides with their labels inside the card.

Colours come from the NodeGraphNode UIID (background, text) and NodeGraphNodeSelected (the outline of a selected node), ports from NodeGraphPort. A node's style key picks its strip colour from setAccent; a node without one uses the selection colour.
