I have different treeviews that use the same model, each on a notebook 
tabs.  Whenever a row is added I call gtk_tree_model_foreach(), which 
passes in the model, to get the highest line number (user_data is used 
to pass back the number).  My GtkTreeModelForeachFunc function uses a 
static variable to keep track of the highest number.  The problem is if 
the user switches tabs I need to reset the static variable since the 
treview changed.

What I think I'll do is after the gtk_tree_model_foreach() call when I 
get my line number I'll call my GtkTreeModelForeachFunc with NULLs which 
 will reset my static variable.  That should be acceptable.

Thanks all,
