Thanks for help. I have ran into another issues: I want to draw cca 200 x 200 grid where each cell can contain different shape.
Can I specify in julia box how large will be the canvas? Right now it uses only 50% of screen available. Compose doesn't distribute the objects equally for some reason (see image), how can I fix that? <http://i.imgur.com/KxTac8E.png?1> > I was trying to follow the steps from reactive > <http://julialang.org/Reactive.jl/index.html#derived-signals> simple > animation tutorial, but no window with the ball image pops up ( I have done > it from REPL on my personal computer on windows 8). >
