GtkTreeView column right-click

[Murray Cumming <murrayc murrayc com>]

I'd like to popup a menu when the user right-clicks on a GtkTreeView's
column header.  Does anyone know of any example code for that, or even
an app that does that?

Obviously I don't want to access the private GtkTreeViewColumn::button.
