which number a GtkTreeViewColumn is in a GtkTreeView

[Razvan <razvaneduard xnet ro>]

I have a GtkListStore with 1 column. Data in this column are pointers to 
a structure MyStruct.

Then, I have a GtkTreeView with 4 column. Text displayed in this columns 
comes from MyStruct from the model.

So I use 
gtk_tree_view_column_set_cell_data_func(column,renderer,someGtkTreeCellDataFunc_cb,NULL,NULL)
for each GtkTreeViewColumn.

but in
void someGtkTreeCellDataFunc_cb(GtkTreeViewColumn *tree_column, 
GtkCellRenderer *cell, GtkTreeModel *tree_model,GtkTreeIter 
*iter,gpointer data)

I need to know the number of tree_column to know what member of MyStruct 
to put there.

I have looked through the API but I didn't find anything.

If you have any sugestions I appreciate.
