Expand description
Represents a touch event
Every time the user touches the screen, a new Start
event with an unique
identifier for the finger is generated. When the finger is lifted, an End
event is generated with the same finger id.
After a Start
event has been emitted, there may be zero or more Move
events when the finger is moved or the touch pressure changes.
The finger id may be reused by the system after an End
event. The user
should assume that a new Start
event received with the same id has nothing
to do with the old finger and is a new finger.
A Cancelled
event is emitted when the system has canceled tracking this
touch, such as when the window loses focus, or on iOS if the user moves the
device against their face.
Fields
device_id: DeviceId
phase: TouchPhase
location: PhysicalPosition<f64>
force: Option<Force>
Describes how hard the screen was pressed. May be None
if the platform
does not support pressure sensitivity.
Platform-specific
- Only available on iOS 9.0+ and Windows 8+.
id: u64
Unique identifier of a finger.
