[Glade-users] Adding VBox - cannot find in container

[shadyabhi]

Hi guyz,

So, I just started using glade today and this tutorial said me to add a
VBox to the main window. 

Now, the problem is that I was not able to find the window anywhere in
the Containers. Also, there is now way to add by right clicking the
window1 (which is a GtkWindow) created on the right.

The screenshot for my glade is http://i.imgur.com/T57PQ.png or

I hope you could help me getting started.

Abhijeet
