GtkTreeView: how to get the cell with current focus?

[Lars Paulsen <lars_paulsen web de>]

Hello All,

I got a little problem with a GtkTreeView and with getting the cell 
which actually has got the focus:

From the API documentation it seems like

gtk_tree_view_get_cursor(GTK_TREE_VIEW(tree), &path, &focus_column);

is doing the job. I can handle the path, it gives me the row which has 
the focus. But how do I get the index of the cell from focus_column 
(alias GtkTreeViewColumn)? A web search revealed some old forum entries 
which seem to state that it is not supported.

Do I have to check the column name or compare the addresses of my columns?

Thanks for any help in advance.

Best Regards,
Lars
