Expand description

A single touch event’s data

Fields§

§status: TouchStatus§x: u16

touch (x, y) position

§y: u16§id: usize

Numeric ID assigned to this touch. This ID allows the client to to match different TouchEvents to the same physical touch.

The driver must assign a unique ID to each touch.

§size: Option<u16>

Optional scaled value for the size of the touch. A larger value corresponds to a “fatter” touch. The size values range from 0 to 65535.

If a touchscreen does not provide information about the size of the touch, this must be set to None.

§pressure: Option<u16>

Optional scaled value for the pressure of the touch. A larger value corresponds to a “firmer” press. The pressure values range from 0 to 65536.

If a touchscreen does not provide information about the pressure of a touch, this must be set to None.
