status-notifier: Fix elements display on GTK < 3.20 2017-01-23T18:49:34+00:00 Colomban Wendling cwendling@hypra.fr 2017-01-20T14:49:00+00:00 bd25c5b4c173bb3541f204c60ffb9450a0d010cd On GTK 3.20 onwards, themes are expected to use CSS names rather than widget class names, and apparently CSS names are not inherited. So, a derived widget altering its CSS name won't be styled as its parent classes. Thus, SnItem setting the CSS name "sn-item" avoids being styled as a "button". But on older GTK versions, the widget class being used makes this change ineffective. Fix that by introducing a custom derived button that doesn't draw the unwanted parts.
