Class SwingGraphRenderer

java.lang.Object

org.graphstream.ui.swing.SwingGraphRenderer

All Implemented Interfaces:

org.graphstream.ui.graphicGraph.StyleGroupListener, org.graphstream.ui.view.GraphRenderer<java.awt.Container,java.awt.Graphics2D>

public class SwingGraphRenderer
extends java.lang.Object
implements org.graphstream.ui.view.GraphRenderer<java.awt.Container,java.awt.Graphics2D>, org.graphstream.ui.graphicGraph.StyleGroupListener

2D renderer. The role of this class is to equip each style group with a specific renderer and to call these renderer to redraw the graph when needed. The renderers then equip each node, edge and sprite with a skeleton that gives is main geometry, then selects a shape according to the group style. The shape will be "applied" to each element to draw in the group. The shape will be moved and scaled according to the skeleton. A render pass begins by using the camera instance to set up the projection (allows to pass from graph units to pixels, make a rotation a zoom or a translation) and render each style group once for the shadows, and once for the real rendering in Z order. This class also handles a "selection" object that represents the current selection and renders it. The renderer uses a backend so that it can adapt to multiple rendering targets (here Swing and OpenGL). As the shapes are finally responsible for drawing the graph, the backend is also responsible for the shape creation.
