Examples with GraphicElement org.graphstream.ui.graphicGraph.GraphicElement used on opensource projects

Example 1 with GraphicElement

use of org.graphstream.ui.graphicGraph.GraphicElement in project gs-ui-javafx by graphstream.

the class FunctionInVoid method render.

/**
 * Main rendering method.
 *
 * This works in three phases:
 * - draw all "bulk" elements using renderElement()
 * - draw all "dynamic" elements using renderElement().
 * - draw all "event" elements using renderElement().
 *
 * Before drawing, the setupRenderingPass() and pushStyle() methods are called. The phase 1 is
 * run. Then for each dynamic element in phase 2, before calling renderElement, for each element
 * the pushDynStyle() method is called.
 * Then for each element modified by an event, in phase 3, the before drawing the element, the
 * event is enabled, then pushStyle() is called, then the element is drawn, and finally the
 * event is disabled.
 *
 * This rendering pass is made both for shadows and for regular drawing. The shadow and render
 * arguments allow to specify that we are rendering for shadow, and what element rendering
 * method to use (renderElement() or renderShadow()).
