Is there any layermask in javafx?

[Addez]

I am making a program that is suppose to be simple to use and very interactive.
Now, when someone opens a window, a sort of blue lighting bolt should go from the button to the new windows position.
It will first move in the x axis then do a 45 degree turn towards the point of the window frame.

I can achive this easily if I only had a layermask. Because then I draw the path on the layermask, and as and image I use a blue fading sphere.
This sphere will move along the path and only part of the sphere will be visible. This will give the effect of a bolt.
But I fail to find any tutorial or anything on layermask..
Can you guys help me?
