That listview Fade Effect

[Ommina]

So - in Videos and Music, when the focus changes away from the list and onto the menu, the list noticeably fades until it has focus again.

I'd like to reproduce this, but have not been able to figure out what buttons to push to make it happen.

I did try fussing with the alpha property, but it did not have any effect at all (that I saw, anyway). The skin has an alphaFade attribute, which may or may not be relevant, but if it is, I can't find how to wire it up.

Has anybody made this happen and can point me in the right direction? I'm implementing IScreenPlugin.
