Note that this list is about the development of GTK+ itself. For
questions about application programming you should usually use
gtk-app-devel-list.

To answer your question, try setting the tooltip on column->button
(where column is a GtkTreeViewColumn*).

There's nothing really special with TreeView column headers, except that
the button (in which a user-specified widget is packed) has an
input-only window which covers the button. And that's why user-specified
widgets (like your event box), won't get events and tooltips won't work.


hope this helps,
