Hi Gus!

Thank you for answering, although after testing this seems to be only
one half of the solution.

The other half would be to invalidate or mark the widget for redrawing,
so that there are events to process. Apparently changing the background
color on a widget (hscale in this case) does not do it.

Any further hints?

Many thanks,
Marc
