@hackage / gtk-traymanager

This package wraps the venerable eggtraymanager code, which implements the freedesktop.org system tray protocol. The code seems to have originated somewhere in the GNOME project a long time ago; I took it from trayer-srg. The only change I made was to cast a few long variables in parameters to uint64_t to make interoperability with Haskell easier.

By itself, this code is not a system tray widget. It is, however, an integral part of one. This package exports a simple GObject (for use with gtk2hs) that emits events when system tray events occur. A system tray widget would listen for these events and respond. See the haddock documentation for details.
