[pygtk] GTK window with switchable views, howto?

[Basil Shubin]

Hi friends,

First, excuse me for my english :)

Second, I am shiny new in GTK programming and I have several questions 
to ask:

Here a task, I need a GTK window with a switchable views/panels, for 
example there is default view/panel with a widgets and so on, then if 
user has selected a menu item, then default view/panel should be 
replaced/switched by other view/panel with their own widgets.

Right now I am using Glade3 to layout frame with widget, but I don't 
clearly understanding how I can create a custom panel and then how to 
insert it inside main window. I need several predefined views to switch 
between...

Main problem is: how to accomplish this task by using Glade3 and PyGTK

Thanks for any suggestions.
