I am using adding circle on mouse drag with 5px of radius.It is eaving some gap behind .How to make it smooth.

public void onMouseDragged(MouseEvent event) {
    Circle circleForShape = new Circle();
                    circleForShape.setCenterX(event.getX());
                    circleForShape.setCenterY(event.getY());
                    circleForShape.setRadius(5);
                    circleForShape.setSmooth(true);
                    circleForShape.smoothProperty();
                    circleForShape.setFill(c);
                    group.getChildren().add(circleForShape);
}

Nothing on Mouse Pressed & Mouse released event. Adding image for some clarity .

I guess you've imported the "wrong" Label (e.g. from AWT), which doesn't extend javafx.scene.Node. Make sure it is from the javafx.scene.control package.
