Starting with Plasma Next, KDE doesn't support the XEmbed systray in favor of their own Status Notifier Specification.
This little library allows to easily create a GObject to manage a StatusNotifierItem, handling all the DBus interface and letting you simply deal with the object's properties and signals.
You can simply create a new StatusNotifier using one of the helper function,
e.g. status_notifier_item_new_from_icon_name(), or simply creating an object
as usual - you then just need to make sure to specify property id :
sn = (StatusNotifier *) g_object_new (STATUS_NOTIFIER_TYPE_ITEM,
"id", "app-id",
"status", STATUS_NOTIFIER_STATUS_NEEDS_ATTENTION,
"main-icon-name", "app-icon",
"attention-icon-pixbuf", pixbuf,
"tooltip-title", "My tooltip",
"tooltip-body", "This is an item about <b>app</b>",
NULL);
You can also set properties (other than id) after creation. Once ready, call
status_notifier_item_register() to register the item on the session bus and to
the StatusNotifierWatcher.
If an error occurs, signal registration-failed will be emitted. On success,
property state will be STATUS_NOTIFIER_STATE_REGISTERED.
Once registered, you can change properties as needed, and the proper DBus
signal will be emitted to let visualizations (hosts) know, and connect to the
signals (such as context-menu) which will be emitted when the corresponding
DBus method was called.
Simple as that.
