How do I get the column number in GtkTreeView version 3

In Gtk+ 2, I serving the signal "row-activated" I had access to the column numbers in the following way:

Code:

void on_treeview1_row_activated(GtkTreeView *tree_view, GtkTreePath *path, GtkTreeViewColumn *column, gpointer user_data)
{
  GList *lista_kolumn;
  gint kolumna_nr;   

  lista_kolumn = gtk_tree_view_get_columns ( GTK_TREE_VIEW(column->tree_view) ) ;

  kolumna_nr = g_list_index ( lista_kolumn, (gpointer) column );

  g_printf ( "<<<Kolumna %d>>>\n", kolumna_nr );  
}

but in Gtk+ 3 column->tree_view is private and can not get.
How do I get the column number ?

Hi,

To get access to the Tree View from your Tree View Column you now need to use a function to get the information. Direct access to internal data in structures was deprecated a long time ago in GTK+ v2 and now removed in GTK+ v3.

The function you want is (introduced in version 2.12)

Code:

GtkWidget *         gtk_tree_view_column_get_tree_view  (GtkTreeViewColumn *tree_column);

and you example becomes

Code:

void on_treeview1_row_activated(GtkTreeView *tree_view, GtkTreePath *path, GtkTreeViewColumn *column, gpointer user_data)
{
  GList *lista_kolumn;
  gint kolumna_nr;   

  lista_kolumn = gtk_tree_view_get_columns ( GTK_TREE_VIEW( gtk_tree_view_column_get_tree_view(column) ) ) ;

  kolumna_nr = g_list_index ( lista_kolumn, (gpointer) column );

  g_printf ( "<<<Kolumna %d>>>\n", kolumna_nr ); 
}
