Thank you. That cleared few things.

I will add sample code from text time appropriately.

I did not add vBox because I have already added it in the constructor
of a class. In the same file, later in some function, I am updating
contents of the vBox. As a result, I added the Gtk::Paned to vBox only
and did not add vBox another time. If I add the vBox again, I get this
error:

gtk_box_pack: assertion 'child->parent == NULL' failed

So how to proceed to refresh vBox?
