You should be able to do this without JavaScript by using streaming.

Re: My car is "falling" off the screen green shoes

From: Ruby Student <ruby.student@...>

List: ruby-talk #408025
Hi Martin,

I defined my screen as "fullscreen" and I don't know how to tell the actual
size in order to control the car movements. I have the following:
*Shoes.app fullscreen: true, :title => "VRMQMon", :resizable => true  do
*

   1. How does one determine the size of the screen while in full screen?
   2. How can I tell when the car reached the edges?


Thank you
