List view: Howto get the number of displayed rows?

[Felipe <felipito gmx net>]

Hi,

Perhaps a stupid question, but I searched unsuccessfully in the 
documentation of GtkListStore and GtkTreeModel about the number of rows 
that are currently displayed in a list view. Now I need to know if 
exists a function for this or should I use gtk_tree_model_foreach() to 
count the number of rows "manually"?


Thanks in advance,


Felipe
