"""Abstractions to detect the currently focused window across compositors.
|
|
|
|
Focus detection is implemented as a registry of backends. To add support for a
|
|
new compositor, implement a new ``FocusBackend`` and append its class to
|
|
``focus_backend_classes`` (ordered by priority). ``select_backend`` returns the
|
|
first backend that reports itself as available, so the most specific backend
|
|
for the current session wins.
