You could use TreeView.get_cell_area().  According to the API docs:

http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeView.html#gtk-tree-view-get-cell-area

  If path is NULL, or points to a path not currently displayed, the y and
  height fields of the rectangle will be filled with 0.
  
In other words, if the cell area doesn't overlap the visible area of the
TreeView, these dimensions are just zero.
  
I'm not sure how it works for horizontal scrolling.  Perhaps analogously.
