no-input window possible???

[Juan Antonio Zuloaga Mellino]

Hello,
I like to have a "sticky- always on top - 60%opacity - no input" window, so
I can have a small floating video playing while I'm doing other things,
without having to move the window when it gets in the way.

With "no input", I mean that if I click the window, I actually click the
one that is behind it...
For this I use xwinwrap
http://tech.shantanugoel.com/projects/linux/shantz-xwinwrap

But I wanted to know if there is some way to do this with the awesome api,
to be able to turn the "no input" on/off dynamically.


The code that xwinwrap uses for the no input is
 if (noInput)
    {
        Region region;

        region = XCreateRegion ();
        if (region)
        {
            XShapeCombineRegion (dpy, win, ShapeInput, 0, 0, region,
ShapeSet);
            XDestroyRegion (region);
        }
    }

But my knowledge of  X is very shallow to fully understand it...

Regards.
Juan.
