## Note
This project is modified from KDE's xembed-sni-proxy project, extracted from plasma-workspace.
##XEmbed SNI Proxy
The goal of this project is to make xembed system trays available in Plasma.
This is to allow legacy apps (xchat, pidgin, tuxguitar) etc. system trays[1] available in Plasma which only supports StatusNotifierItem [2].
Ideally we also want this to work in an xwayland session, making X system tray icons available even when plasmashell only has a wayland connection.
This project should be portable onto all other DEs that speak SNI.
##How it works (in theory)
* We register a window as a system tray container
* We render embedded windows composited offscreen
* We render contents into an image and send this over DBus via the SNI protocol
* XDamage events trigger a repaint
* Activate and context menu events are replyed via X send event into the embedded container as left and right clicks
There are a few extra hacks in the real code to deal with some toolkits being awkward.
##Build instructions
cmake .
make
sudo make install
After building, run `xembedsniproxy`.
