Hide right scroll bar??

How would I hide the right scroll bar in this example?

var obj = new AW.UI.Grid;
obj.setColumnCount(4);
obj.setRowCount(0);
obj.setSize(800,20);
obj.setStyle("border-color", "white");
obj.setHeaderText("header text", 0);

document.write(obj);


Thank you!!

Maybe this way -

obj.setScrollBars("none");
obj.onScrollBarsChanging = function(){
return 1; // cancel change
}

Righteous! That worked. Thank you!
