"""Process that sends stuff to the GUI.
|
|
|
|
It should be started via input-remapper-control and pkexec.
|
|
|
|
GUIs should not run as root
|
|
https://wiki.archlinux.org/index.php/Running_GUI_applications_as_root
|
|
|
|
The service shouldn't do that even though it has root rights, because that
|
|
would enable key-loggers to just ask input-remapper for all user-input.
|
|
|
|
Instead, the ReaderService is used, which will be stopped when the gui closes.
|
|
|
|
Whereas for the reader-service to start a password is needed and it stops whe
|
|
the ui closes.
|
|
|
|
This uses the backend injection.event_reader and mapping_handlers to process all the
|
|
different input-events into simple on/off events and sends them to the gui.
