public class DefaultGraphNodeRenderer

Object
DefaultGraphNodeRenderer

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.

Constructors

public DefaultGraphNodeRenderer()

Methods

`public void setAccent(String styleKey, int rgb)`	Maps a node style key to the colour of its strip and its ports.
`public int getAccent(String styleKey, int fallback)`	The colour of a style key, or `fallback` when none was set.
`public void paintNode(Graphics g, NodeGraph graph, GraphNode node, int x, int y, int w, int h, boolean selected)`	Paints `node` into the rectangle.
