Future Roadmap

Use GDBus

A whole bunch of Xfce uses DBus communication (xfconf, thunar, xfce4-panel, xfce4-session, xfce4-appfinder, tumbler). Most of this is done through generating dbus binding (xml > dbus-binding-tool > code) and using the dbus-glib library.

Since 2.26 glib has its own implementation for this to replace dbus-glib, so it is wise to switch to this API and drop dbus-glib.

Advantages are: gdbus does not include the dbus library and uses GIO streams. It's therefore a lighter implementation. dbus-glib is also not maintained as much as gdbus.


  1. Start with xfconf and port the code and generation to gdbus. It might be wise to use direct proxy communication in libxfconf, because the calls are sync.
  2. Port the other components to gdbus.
  3. Open bugs for the various components and attach the patches.
