Example 1 with RotateEvent

use of javafx.scene.input.RotateEvent in project NMEAParser by tvesalainen.

the class RotateEmulator method handle.

@Override
public void handle(MouseEvent me) {
    node = (Node) me.getTarget();
    double sx = me.getScreenX();
    double sy = me.getScreenY();
    Point2D local = node.screenToLocal(sx, sy);
    if (local == null) {
        a = 0;
        angle = 0;
        totalAngle = 0;
        return;
    }
    Bounds bounds = node.getBoundsInLocal();
    double cx = local.getX() - bounds.getWidth() / 2;
    double cy = local.getY() - bounds.getHeight() / 2;
    EventType<? extends MouseEvent> eventType = me.getEventType();
    if (eventType == MOUSE_PRESSED) {
        a = Math.toDegrees(Math.atan2(cy, cx));
        angle = 0;
        totalAngle = 0;
        RotateEvent re = createRotateEvent(me, ROTATION_STARTED);
        Event.fireEvent(node, re);
    } else {

        double da = Math.toDegrees(Math.atan2(cy, cx));
        angle = da - a;
        a = da;
        totalAngle += angle;
