ActionScript Language Reference

The initial value of the _visible property is true for all text fields, even for text fields that

are fully transparent or completely off stage. The

_visible property changes only when it is

modified explicitly by a script; think of it as a way to show and hide text fields program-

matically, not as a reflection of all factors, such as position and transparency, that can

affect a field’s visibility.

Hiding a text field using the

_visible property is preferred to setting it to fully transparent

or moving it off stage because the Flash Player does not attempt to draw text fields with

_visible set to false, thus improving rendering performance.

Example

The following code hides theField_txt:

this.createTextField("theField_txt", 1, 0, 0, 200, 20);

theField_txt.text = "You won't see this!";

theField_txt._visible = false;
