If you have caused the GtkVBox to be Realized, meaning all the widget
have done their size negotiations, then to get the x/y position of the
desired GtkTextView - relative to the GtkVBox, you can try something
like this.

if ( GTK_WIDGET_REALIZED(gvbox) ) 
{
    GTK_WIDGET(gkvbox)->allocation.height;  /* this is the allocated
height */
    GTK_WIDGET(desired_gtktextview)->allocation.y; /* this would be your
scroll to point to display this widget */
                                                                                    /* this point is inside the gvbox's height range */
}

Hope this helps

James,
