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.
§

Group

group announced

Sent on wp_tablet_pad initialization to announce available groups. One event is sent for each pad group available.

This event is sent in the initial burst of events before the wp_tablet_pad.done event. At least one group will be announced.

Fields

§

Path

path to the device

A system-specific device path that indicates which device is behind this wp_tablet_pad. This information may be used to gather additional information about the device, e.g. through libwacom.

The format of the path is unspecified, it may be a device node, a sysfs path, or some other identifier. It is up to the client to identify the string provided.

This event is sent in the initial burst of events before the wp_tablet_pad.done event.

Fields

§path: String

path to local device

§

Buttons

buttons announced

Sent on wp_tablet_pad initialization to announce the available buttons.

This event is sent in the initial burst of events before the wp_tablet_pad.done event. This event is only sent when at least one button is available.

Fields

§buttons: u32

the number of buttons

§

Done

pad description event sequence complete

This event signals the end of the initial burst of descriptive events. A client may consider the static description of the pad to be complete and finalize initialization of the pad.

§

Button

physical button state

Sent whenever the physical state of a button changes.

Fields

§time: u32

the time of the event with millisecond granularity

§button: u32

the index of the button that changed state

§

Enter

enter event

Notification that this pad is focused on the specified surface.

Fields

§serial: u32

serial number of the enter event

§tablet: ZwpTabletV2

the tablet the pad is attached to

§surface: WlSurface

surface the pad is focused on

§

Leave

leave event

Notification that this pad is no longer focused on the specified surface.

Fields

§serial: u32

serial number of the leave event

§surface: WlSurface

surface the pad is no longer focused on

§

Removed

pad removed event

Sent when the pad has been removed from the system. When a tablet is removed its pad(s) will be removed too.

When this event is received, the client must destroy all rings, strips and groups that were offered by this pad, and issue wp_tablet_pad.destroy the pad itself.
