Transparent EventBox Background

[Andy Grebe <andyg apogeelabs com>]

I'm attempting to move an Eventbox over an eventbox on a gtkfixed. 
However the one which I'm trying to move over the other contains an
image with transparency.  Since, when I don't use the window for the
eventbox, you can see what's behind it, except it then moves under the
first eventbox.  The first event box shows it's window since it's
background is a nice image for a label which is on top of it.

Is there any way to set the background of the eventbox to transparent,
while still using the eventbox's window?

Thanks
