First of all, thanks for your help. Now all seems to work.
One thing I don't understand about the top level window. If I put an
image or color
in the top level window using gtk I see only gray but if I modified
directfbrc with an bg-image
I see the background image, and the three widget are trasparent.
vbox -> drawing area
button
