package com.codename1.ui.graph
NodeGraph: a pannable, zoomable view of a com.codename1.graph.GraphModel
where nodes are dragged, connected and grouped.
It serves two kinds of picture with one component. A diagram of a
system, where boxes stand for services or ideas and edges join them, is
made of nodes without ports; a node editor, where data flows from outputs
to inputs of a matching type, is made of nodes with GraphPorts. Both can
be laid out by hand or by a com.codename1.graph.arrange.GraphArrangement.
Nodes and edges are painted, with no component behind each, so a graph
of thousands of nodes costs what is on screen. A node that needs a real
control gets one from a NodeComponentFactory. Colours and fonts come
from the NodeGraph* UIIDs.
Types
class DefaultGraphEdgeRenderer | Paints an edge as a line with an arrowhead on a directed edge and its label in a pill at the middle. |
class 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. |
class GraphAdapter | A GraphListener that refuses nothing and ignores everything; override what you need. |
interface GraphEdgeRenderer | Paints an edge along the path the graph computed for it. |
interface GraphListener | What a NodeGraph tells an application about. |
interface GraphNodeRenderer | Paints a node. |
interface NodeComponentFactory | Makes a real component for a node’s body, such as a slider in a node editor. |
class NodeGraph | A pannable, zoomable view of a GraphModel where nodes are dragged, connected and grouped: a system diagram, a mind map, or a node editor. |
