Struct input::event::tablet_tool::TabletToolProximityEvent

pub struct TabletToolProximityEvent { /* fields omitted */ }

Signals that a tool has come in or out of proximity of a device with the DeviceCapability::TabletTool capability.

Proximity events contain each of the current values for each axis, and these values may be extracted from them in the same way they are with TabletToolAxisEvent events.

Some tools may always be in proximity. For these tools, proximity events with ProximityState::In are sent only once after DeviceAddedEvent, and proximity events with ProximityState::Out are sent only once before DeviceRemovedEvent.

If the tool that comes into proximity supports x/y coordinates, libinput guarantees that both x and y are set in the proximity event.

When a tool goes out of proximity, the value of every axis should be assumed to have an undefined state and any buttons that are currently held down on the stylus are marked as released. Button release events for each button that was held down on the stylus are sent before the proximity out event.

Implementations

impl TabletToolProximityEvent

pub fn proximity_state(&self) -> ProximityState

Returns the new proximity state of a tool from a proximity event.

Used to check whether or not a tool came in or out of proximity during an TabletToolProximityEvent.

See Handling of proximity events for recommendations on proximity handling.
