JavaFx 2.x : How to draw dashed or dotted lines?

I would like to dynamically change the draw of a line from solid, dotted or dashed: it seems I have to use line.setStroke, is it the correct method?

And, how to accomplish this?

Thanks

No that is not the correct method, setStroke sets the color of the stroke.
Correct method is getStrokeDashArray().add():

Line line1 = new Line(20, 40, 270, 40);
line1.getStrokeDashArray().addAll(25d, 20d, 5d, 20d);

Line line2 = new Line(20, 60, 270, 60);
line2.getStrokeDashArray().addAll(50d, 40d);

Line line3 = new Line(20, 80, 270, 80);
line3.getStrokeDashArray().addAll(25d, 10d);

Line line4 = new Line(20, 100, 270, 100);
line4.getStrokeDashArray().addAll(2d);

Line line5 = new Line(20, 120, 270, 120);
line5.getStrokeDashArray().addAll(2d, 21d);

pane.getChildren().addAll(line1, line2, line3, line4, line5);

StrokeDashArray defines the pattern of line and gap sequences. See the following different patterns as output of aboves:

Of course by manipulating the StrokeDashArray array elements you can change the pattern dynamically.
