[pygtk] Handler for showing window

[Petr Hracek]

Hi folks,

I have a little bit simple question
In Glade3 I have GtkWindow object
with GtkButton and TextView widget.

What is my goal.
I would like to run some actions when all widgets (like TextView, 
GtkButton) are really visible.

It means when this condition is satisfied then some actions are run and 
output of that actions
are logged into TextView widget.

Actually now I could not find what event should be used for.
It should be some event of GtkWindow, right?

There are some events like visibility_event or show_event, ...
Any advises?
