Unfortunately, I think you will find in GTK visibility refers to whether a
widget _should_ be displayed,
not whether it _is_ displayed.
I tried that signal on my test - no go. [☹]

I've raped the Calculator example from here

LinuxCNC Documentation Wiki: GladeVCP Custom
Widgets<http://wiki.linuxcnc.org/cgi-bin/wiki.pl?GladeVCP_Custom_Widgets>

Here we attempt to describe how to build a custom glade widget using python.
Note i am not a programmer by trade, more of a hacker, so what I show you
works, but ...
, "ported" it to PyGObject (gtk3) and added some "features" for showing the
"notify::visible" functionality.

I am on windows and I am developing a pygtk app. I need to know when a window
is visible or hidden by another window. In order to stop an heavy drawing
process.
