How to setTextFormat to selection within textArea component

[Pluda]

Hello,

Having one TextArea in stage using

Code:

var tf:TextArea = new TextArea();
tf.setSize(200,200);
tf.move(100, 100);

and then using this

Code:

tf.getTextFormat(tf.selectionBeginIndex, tf.selectionEndIndex);
trace("caretIndex:", tf.caretIndex);
trace("selectionBeginIndex:", tf.selectionBeginIndex);
trace("selectionEndIndex:", tf.selectionEndIndex);

why do I get this error?

1061: Call to a possibly undefined method getTextFormat through a reference with static type fl.controls:TextArea.

hum... so it's not possible to make one rich text editor in flash using textArea and As3...

I've made my own a couple of years ago, but is as2 and I wanted to use as3

I'm trying this code and get this error

Code:

function funcoes_botoes(e:MouseEvent, b:String) : void {
trace(b);
if(b == "bold_btn") {
tf.textField.getTextFormat(tf.selectionBeginIndex, tf.selectionEndIndex);
trace("caretIndex:", tf.textField.caretIndex);
trace("selectionBeginIndex:", tf.textField.selectionBeginIndex);
trace("selectionEndIndex:", tf.textField.selectionEndIndex);
//
var fn:TextFormat = new TextFormat;
//
if (fn.bold) {
fn.bold = false;
} else {
fn.bold = true;
}
tf.textField.setTextFormat( fn,  tf.textField.selectionBeginIndex, tf.textField.selectionEndIndex);
}

}

and the error

Error #2006: The supplied index is out of bounds.
