/**
|
|
* Edje example demonstrating how to use multiseat filtering.
|
|
*
|
|
* It presents 4 widgets that can be controlled by:
|
|
* * seat1 only
|
|
* * seat2 only
|
|
* * seat1 + seat2
|
|
* * any seat
|
|
*
|
|
* You'll need at least one Evas engine built for it (excluding the
|
|
* buffer one) that supports multiseat. It may be wayland or
|
|
* X11 with VNC support. Using other engines will lead you to a
|
|
* situation where all seats are reported as the same one ("default").
|

* edje_cc multiseat_filter.edc && gcc -o edje-multiseat-filter edje-multiseat-filter.c `pkg-config --libs --cflags evas ecore ecore-evas edje`
