GtkTreeView : why so many "refresh"

["Francois MARTIN" <fmartin caicheuvreux com>]

Hi to all

I have two questions about the GtkTreeView used to display a GtkListStore :

1. I have specified a function 'my_cell_data_func()' using
gtk_tree_view_column_set_cell_data_func() on each column of a view.
By calling gtk_tree_model_row_changed() on one of the rows of the model, I
am called into my_cell_data_func() for each column of the view for the
changed row (it's seem logical).
But, if the changed row is  visible (even partially), I am then called into
my_cell_data_func() again: for each visible rows and for each columns of
the view (including the changed row itself) ! Are these calls necessary ?
Note that there is no auto sort on the view, nor auto-resize on the
columns.

2. Is there a way to prevent 'my_cell_data_func()' from being called each
time the mouse pointer moves over a row (enters and leaves the row area in
fact), while keeping selection enabled ?
