don't. GtkTooltips has long since been deprecated, and should never be
used in newly written code:

    https://developer.gnome.org/gtk2/stable/GtkTooltips.html

you should simply set the tooltip through the
Gtk2::Widget::set_tooltip_text() method (or set_tooltip_markup()
method, if you want to use Pango markup in the tooltips).

the page for the tooltip API is here:

    https://developer.gnome.org/gtk2/stable/GtkTooltip.html

it allows you to create custom tooltips, with complex contents (like
images) and to listen to specific coordinates (for instance, if you
have a custom canvas). unlike the old GtkTooltips API, the tooltip API
allows you to set tooltips on complex widgets like Gtk2::TreeView.

if you experience similar issues with the tooltip API feel free to
open a bug against the GTK+ product on https://bugzilla.gnome.org.

ciao,
 Emmanuele.
