Emit property change signals for the IsStatusNotifierHostRegistered and RegisteredStatusNotifierItems properties in StatusNotifierWatcher, so code relying on the PropertiesChanged signal, instead of signals such as StatusNotifierHostRegistered, can work properly. A library that is affected by this is the libappindicator-gtk3* library and it can cause tray icons to be missing after starting swaybar due to a race condition, as follows: * An application using libappindicator-gtk3 starts, e.g. nm-applet. * Some time later, swaybar starts. * swaybar creates the StatusNotifierWatcher. * libappindicator-gtk3 observes the new watcher, but it sees that IsStatusNotifierHostRegistered=false, so it falls back to the Freedesktop System tray protocol. * swaybar creates the StatusNotifierHost. At this point, libappindicator-gtk3 should "un-fallback" back to SNI. However, since swaybar does not emit the PropertiesChange signal on IsStatusNotifierHostRegistered, libappindicator-gtk3 doesn't get notified, and stays in fallback state forever. * As a result, nm-applet will not show in the swaybar tray. This race can be made reliable by inserting a 1-second long sleep here: |
