How do I get the number

[Igor Korot <ikorot01 gmail com>]

Hi, ALL,
For the GtkTreeView there is a "row-activated" signal:
https://developer.gnome.org/gtk3/stable/GtkTreeView.html#GtkTreeView-row-activated.

That function receives as a parameter

column the GtkTreeViewColumn in which the activation occurred.

The problem is (at least as I see it) is that it is not a simple integer
for the column number.

Is there a simple way to get a column number on which I activated
the row from this signal?

Thank you.
