hi all

why ?
code

createClassObject(mx.controls.UIScrollBar, “my_sb”, 320);
my_sb.setScrollTarget(my_txt);
// Size it to match the text field.
my_sb.setSize(16, my_txt._height);

// Move it next to the text field.
my_sb.move(my_txt._x + my_txt._width, my_txt._y);

// Load text to display and define onData handler.
var my_lv:LoadVars = new LoadVars();

my_lv.onData = function(src:String) {
if (src != undefined) {
//my_txt.htmlText = src;
my_txt.text = src;
my_txt.setTextFormat(my_fmt);
} else {
my_txt.text = “Error loading text. deinost”;
}
};
my_lv.load(“test.txt”);
