Hi all,

After lots of years I finally got around to porting my widget
GtkImageViewer to gtk3. After doing lots of reading of man pages, did I
realize that i can turn off double buffering. I did it, and everything
worked fine, except for one artefact. Once I turned it off, the scrolled
bars of the parent widget GtkScrolledWindow, would no longer be shown.

Is this a bug? Or am I missing something.

The widget can be found in http://github.com/dov/gtkimageviewer , branch
gtk. The application giv, built around gtkimageviewer may be found in
http://github.com/dov/giv , branch gtk3.

Regards,
Dov
