Currently i'm setting a constant value (e.g. 13), and display only
the latest # datasets in a row.

My software updates the TreeModel (Liststore) every 0.5sec., to
update the TreeModel i'm clearing it and appending my latest
datasets.

I'm having 3k datasets and couldn't append every 0.5sec. all
my datasets just to display the latests visible rows. But the
TreeModel or the Liststore should know how many rows are
visible, cause they are drawing it, i thought/hoped there where
a function like gtk_list_store_get_visible_rows().

If i would drop the ScrollingWidget, is there a way to determine
the visible rows?

Thanks in advance.
