Migrating from SexyUrlLabel to GtkLabel GTK+ 2.18 supports showing links inside a #GtkLabel, similar to SexyUrlLabel. Porting from SexyUrlLabel to GtkLabel is relatively straightforward. GtkLabel accepts links in the markup using the same HTML a notation that SexyUrlLabel uses. In addition to the href attribute, GtkLabel accepts a title attribute that is displayed as a tooltip on the link. Instead of sexy_url_label_set_markup(), just call gtk_label_set_markup(). One difference between the two APIs is that the ::url-activated signal from SexyUrlLabel has been replaced by the #GtkLabel::activate-link signal. The need for connecting to this signal is greatly reduced, since GtkLabel has a default handler that calls gtk_show_uri().
