Question

I’m trying set the alpha to 50% on some radiobuttons in AS3.
The problem is that the radiobutton labels won’t change.

Anyone know how to fix this?

Answer 1

you have to use embedded fonts for your labels. As the documentation states:

• Client environment does not need the font to be installed.
• Embedded fonts are anti-aliased, which means that their edges are smoothed for easier readability. This is especially apparent when the text size is large.
• Embedded fonts can be partially or fully transparent.
• Embedded fonts can be rotated.
• Embedded fonts provide smoother playback when zooming.
• Text appears exactly as you expect when you use embedded fonts.
• When you embed a font, you can use the advanced anti-aliasing information that provides clear, high-quality text rendering in SWF files. Using advanced anti-aliasing greatly improves the readability of text, particularly when it is rendered at smaller font sizes. For more information about advanced anti-aliasing, see Using advanced anti-aliasing.

Hope this helps.

In reply to Kekoa:

This sample makes radio control almost invisible but the label is not affected by alpha change:

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:RadioButton label="Some label here" alpha=".1" />
</mx:WindowedApplication>

And with embedded font (make sure you have assets/arial.ttf):

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:Style>
        @font-face {
            src: url("assets/arial.ttf");
            fontFamily: Arial;
            fontStyle: normal;
            fontWeight: normal;
        }
        .myClass {
            fontFamily: Arial;
        }
    </mx:Style>
    <mx:RadioButton label="Some label here" alpha=".1" />
</mx:WindowedApplication>

This one works fine.
