_alpha (TextField._alpha property)

Sets or retrieves the alpha transparency value of the text field. Valid values are 0 (fully transparent) to 100 (fully opaque). The default value is 100. Transparency values are not supported for text fields that use device fonts. You must use embedded fonts to use the _alpha transparency property with a text field.

Availability: ActionScript 1.0; Flash Player 6

Example

The following code sets the _alpha property of a text field named my_txt to 20%. Create a new font symbol in the library by selecting New Font from the Library options menu. Then set the linkage of the font to my font. Set the linkage for a font symbol to my font. Add the following ActionScript code 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;

The MovieClip.getNextHighestDepth() method used in this example requires Flash Player 7 or later. If your SWF file includes a version 2 component, use the version 2 components' DepthManager class instead of the MovieClip.getNextHighestDepth() method.
