I tried this:

     scrolled.emit('scroll-child', gtk.SCROLL_PAGE_FORWARD, False)

and it's scrolling the treeview, but it doesn't move the selection like when 
the treeview has the focus and I press PgDown there. 

I have the feeling it would be much simpler to send a PgDown keypress to the 
treeview somehow. I made a Winforms GUI recently and there it was trivial to 
send keypresses to an other widget using SendKeys. Surely, after all these 
years of development GTK has to have some method to do that.
