The "row_inserted" and "row_deleted" signals in the GtkTreeModel are each called with the GtkTreePath of the row in question:
The "row-inserted" signal
void user_function (GtkTreeModel *tree_model,
GtkTreePath *path,
GtkTreeIter *iter,
gpointer user_data)
The "row-deleted" signal
void user_function (GtkTreeModel *tree_model,
GtkTreePath *path,
gpointer user_data)

Subject: TreeView/ListStore reordering by DND
I have a simple list display built of a ListView and ListStore as described in https://developer.gnome.org/gtk3/stable/GtkTreeView.html
I used gtk_tree_view_set_reorderable () to allow the user to reorder the list by grabbing rows and moving it up or down.
>From
https://developer.gnome.org/gtk3/stable/GtkTreeView.html#gtk-tree-view-set-reorderable
we have:
"The developer can listen to these changes by connecting to the model's row_inserted and row_deleted signals."
It seems that a "row_inserted" signal is emitted followed by a "row_deleted" signal.
But how can I detect the row numbers of the two exchanged rows?
gtk_tree_path_get_indices ()
https://developer.gnome.org/gtk3/stable/GtkTreeModel.html#gtk-tree-path-get-indices
may work in the signal handler? But it is not very easy to find the relation between the two exchanged rows and the indices.
Are better options available?
