TextField._alpha Property

read/write
theField._alpha
Description
The floating-point _alpha property specifies the opacity (or, conversely, the transparency)
of
theField as a percentage—0 is completely transparent, whereas 100 is completely

theField are all affected. The _alpha prop-

theField’s font is embedded and exported with the movie. A font can
be embedded at authoring time with the Property inspector’s Character button or at
runtime with the
embedFonts property. For important details on font embedding, see
TextField.embedFonts.
Example
Assuming its font has been exported with the movie, the following code makes theField_txt

theField_txt.embedFonts = true;
theField_txt._alpha = 50;
