List and treeview tooltips

["Manuel Op de Coul" <manuel op de coul eon-benelux com>]

I was using eventboxes to show tooltips on the labels of
column headers in columned lists. Disappointed that all my
carefully written tips didn't work anymore when moving from
1.2 to 2.2, I reported this bug to bugzilla.
http://bugzilla.gnome.org/show_bug.cgi?id=117978

Now I'm trying to put tooltips on a gtk_tree_view by setting an
eventbox as column widget, but it also doesn't work!
What went wrong here? When I use a button instead of an
eventbox as column widget, no tooltip either.
Even though the above bug refers to a deprecated widget,
now with this problem also occurring on a treeview, I
hope it will get fixed for both.
Is there a workaround?

By the way, it still seems necessary to put a label in an
eventbox to display tooltips, but labels now respond to
mouse events (labels can be selectable).

Also, I'd hate to see clists go away! They're much simpler
to use.
