How can I make horizonal auto scrolling in JList?

Question

I want the horizontal scrollbar to appear only if one of the rows of the JList is larger than the Jlist.
by the way, the JList is captured in JScrollPane, but I can have only vertical scrollbar.
thanks, Lior.

Your answer is not exactely I want.
But I got hint from your answer.
All I want is "How I can split multilined text into dozen edittext field?"
So I can make this from your sourcecode.
Your answer is so helpful.
Thank you.
var win = new Window ("dialog", "test");
win.orientation = "column";
var charLen=30;
var copytext = [];
var form0 = win.add ("edittext", [0, 0, 150, 200], "", {multiline:true});
form0.height = 100;
var form1 = win.add ("edittext", undefined, "",{readonly:true});
form1.characters = charLen;
var form2 = win.add ("edittext", undefined, "",{readonly:true});
form2.characters = charLen;
var form3 = win.add ("edittext", undefined, "",{readonly:true});
form3.characters = charLen;
form1.active = true;
form0.onChanging = function(){
    form1.text = form0.text.split('\n')[0]
form2.text = form0.text.split('\n')[1]
form3.text = form0.text.split('\n')[2]
win.show();
