I am writing a front-end app that could make use of a transparent window, i.e., a small window for an external call to mplayer to attach to for playing a video -- but with a larger window on top of that with a graphic image of a TV or monitor, and allowing for a transparent viewing tube to allow the video to show through it.

I saw a boolean attribute for set_layered(), but I could not find any practical example of what it does, or if that could help my cause. Does such a feature exist? Thanks.
