Example 1 with Style

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

the class ArrowOnEdge method makeOnCurve.

private void makeOnCurve(boolean forShadow, DefaultCamera2D camera) {
    Tuple<Point2, Double> tuple = CubicCurve.approxIntersectionPointOnCurve(theEdge, theConnector, camera);
    Point2 p1 = tuple.x;
    double t = tuple.y;
    Style style = theEdge.getStyle();
    Point3 p2 = CubicCurve.eval(theConnector.fromPos(), theConnector.byPos1(), theConnector.byPos2(), theConnector.toPos(), t - 0.05f);
    // XXX The choice of the number above (0.05f) is problematic
    Vector2 dir = new Vector2(p1.x - p2.x, p1.y - p2.y);
    // Clearly it should be chosen according to the length
    dir.normalize();
    // of the arrow compared to the length of the curve, however
    dir.scalarMult(theSize.x);
    // computing the curve length (see CubicCurve) is costly. XXX
    Vector2 per = new Vector2(dir.y(), -dir.x());
    per.normalize();
    per.scalarMult(theSize.y);
    // Create a polygon.
    theShape = new Path2D(5, true);
