TextField._alpha

Availability

Flash Player 6.

Usage

my_txt._alpha:Number

Description

Property; sets or retrieves the alpha transparency value of the text field specified by my_txt. Valid

values are 0 (fully transparent) to 100 (fully opaque). The default value is 100. Transparency

values are not supported for text files that use device fonts. You must use embedded fonts to use

the

_alpha transparency property with a text field.

Example

The following code sets the _alpha property of a text field named my_txt to 20%. Set the linkage

for a font symbol to

my font. Add the following ActionScript to your FLA or AS file:

var my_fmt:TextFormat = new TextFormat();

my_fmt.font = "my font";

// where 'my font' is the linkage name of a font in the Library

this.createTextField("my_txt", this.getNextHighestDepth(), 10, 10, 100, 22);

my_txt.border = true;

my_txt.embedFonts = true;

my_txt.text = "Hello World";

my_txt.setTextFormat(my_fmt);

my_txt._alpha = 20;
