I´m desperately looking for any information on how to set Widgets transparent in Homescreen and normal mode to show the actual themes background color or image or at least let it shine through.

Currently i´m working on an already pretty advanced widget ("Symbian60.mobi Fußball News Widget") and set almost any background to transparent or "none", tried using transparent gif-images as background and various other ways and workarounds, but do not seem to succeed at all. Whatever i try, it all results at least in a white background as it seems.

Am I doing something wrong or is what i try impossible anyway - at least with WRT Widgets? I have seen (Homescreen Widgets at least) that show the theme background, as all of the built-in widgets but also some third-party apps and widgets like Twittix do. Any light that could be shed on this issue would be highly appreciated!
