Hi all

I am drawing some text on the screen, which is changed every 3 seconds.  
I need to get the canvas to change when the text does. If I move a  
window over the text on the canvas, it redraws the exposed parts with  
the new text, but I need a way to automatically refresh the whole canvas  
when the text is updated. Is this possible? I have searched on  
[http://www.fxruby.org/doc/api/](http://www.fxruby.org/doc/api/) and tried refresh, repaint and  
forceRepaint which are mentioned there but none of these seem to work.
