#!/usr/bin/env python3 """Frametop Input Settings: choose and map input devices for the universal 3D mouse. A Kirigami (QML) app with a Python backend. It runs in the dev container and talks to the input relay over its control socket (@frametop_relay): - Devices: every USB/Bluetooth mouse and keyboard, a live activity light to identify them, and a role for each (3D pointer, pass through, ignore). - Buttons: press a button or key on a pointer device, then pick an action. - Controllers: the same for the Frame controllers' buttons. They're read by the pointer helper through SteamVR input (@ft_pointer_helper: vrstatus, vrglobal), and a mapped button is taken from games. - Pointer: speed, dot size, distance and the rest, applied live. - Gaze: the pointer's gaze mode (@ft_pointer_helper "gaze") and the gaze service (gaze/ft-gazed, @ft_gazed: status, forget, reload). - Bluetooth: paired devices, and re-applying the Bluetooth LE fixes after pairing. Rules go to ~/.config/frametop-input.json and pointer settings to ~/.config/frametop.conf; then the relay (and through it the helper) reloads. Launch with input-settings/ft-input-settings (host wrapper).
