public border : Boolean
Specifies if the text field has a border. If true, the text field has a border. If false, the text field has no border.
The following example creates a text field called my_txt, sets the border property to true, and displays some text in the field.
this.createTextField("my_txt", this.getNextHighestDepth(), 10, 10, 320, 240);
my_txt.border = true;
my_txt.text = "Lorum ipsum";
