I want my GTK application to have a status icon in the system tray, I have got this working quite nicely using a StatusIcon, however this has been deprecated:
gtk_status_icon_new has been deprecated since version 3.14 and should not be used in newly-written code.
Use notifications
The documentation says "Use notifications" but I have no idea what this actually means. I interpret this to mean "use desktop notifications", but as far as I can tell that serves an entirely different purpose. I want an always-visible system tray icon, not a temporary popup notification. Despite that, I can't find anything else which would seem to be what is meant by "Notifications".
Does there exist a new replacement for GtkStatusIcon which provides an icon in the system tray, with support for receiving mouse click/scroll signals and displaying popup menus?
