[Laszlo-user] Scroll text

[Alfeu Marcatto]

I have a text object with a vertical scrollbar to show system messages 
(same as Debug window).
When a message is added to the box I want show the last line.
How can I scroll the text to the last line programatically?
The step() function scrolls but it need the quantity of lines and I 
don't know how I get that.

Thanks
