Module interaction 

Host-owned input capabilities shared by the retained widget tree.

Apps describe semantic controls once. The host updates this environment from platform events, and controls adapt their hit targets and hover-only affordances without app code branching on raw winit events.

Structs

InputAvailability

A compact set of the input devices discovered for this session.

InteractionEnvironment

Runtime interaction information propagated by the host to every widget.

TouchPointerEmulator

Converts direct touch into the toolkit’s ordinary pointer contract.

Enums

ControllerFamily

Controller legend/layout used when rendering face buttons.

InputDevice

Devices known to be available in this session. This is deliberately separate from InputModality: moving a mouse must not make a connected touchscreen or controller disappear from shortcut help.

InputModality

The kind of interaction most recently used.

KeyboardFamily

Physical legends printed on the connected keyboard. Tilo may run on Linux with an Apple keyboard attached, so this cannot be inferred from the OS.

PointerPrecision

Accuracy of the active pointing device.

TouchPointerEvent

Pointer events synthesised from direct touch, so ordinary widgets work on a touchscreen without interpreting contact streams themselves.
