Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Motion

pointer relative motion event

The pointer has moved by a relative amount to the previous request.

Values are in the global compositor space.

Fields

§time: u32

timestamp with millisecond granularity

§dx: f64

displacement on the x-axis

§dy: f64

displacement on the y-axis

§

MotionAbsolute

pointer absolute motion event

The pointer has moved in an absolute coordinate frame.

Value of x can range from 0 to x_extent, value of y can range from 0 to y_extent.

Fields

§time: u32

timestamp with millisecond granularity

§x: u32

position on the x-axis

§y: u32

position on the y-axis

§x_extent: u32

extent of the x-axis

§y_extent: u32

extent of the y-axis

§

Button

button event

A button was pressed or released.

Fields

§time: u32

timestamp with millisecond granularity

§button: u32

button that produced the event

§state: WEnum<ButtonState>

physical state of the button

§

Axis

axis event

Scroll and other axis requests.

Fields

§time: u32

timestamp with millisecond granularity

§axis: WEnum<Axis>

axis type

§value: f64

length of vector in touchpad coordinates

§

Frame

end of a pointer event sequence

Indicates the set of events that logically belong together.

§

AxisSource

axis source event

Source information for scroll and other axis.

Fields

§axis_source: WEnum<AxisSource>

source of the axis event

§

AxisStop

axis stop event

Stop notification for scroll and other axes.

Fields

§time: u32

timestamp with millisecond granularity

§axis: WEnum<Axis>

the axis stopped with this event

§

AxisDiscrete

axis click event

Discrete step information for scroll and other axes.

This event allows the client to extend data normally sent using the axis event with discrete value.

Fields

§time: u32

timestamp with millisecond granularity

§axis: WEnum<Axis>

axis type

§value: f64

length of vector in touchpad coordinates

§discrete: i32

number of steps

§

Destroy

destroy the virtual pointer object

This is a destructor, once received this object cannot be used any longer.
