Variants (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.

Name

tablet device name

A descriptive name for the tablet device.

If the device has no descriptive name, this event is not sent.

This event is sent in the initial burst of events before the zwp_tablet_v2.done event.

Fields

name: String

the device name

Id

tablet device vendor/product id

The vendor and product IDs for the tablet device.

The interpretation of the id depends on the zwp_tablet_v2.bustype. Prior to version v2 of this protocol, the id was implied to be a USB vendor and product ID. If no zwp_tablet_v2.bustype is sent, the ID is to be interpreted as USB vendor and product ID.

If the device has no vendor/product ID, this event is not sent. This can happen for virtual devices or non-USB devices, for instance.

This event is sent in the initial burst of events before the zwp_tablet_v2.done event.

Fields

vid: u32

vendor id

pid: u32

product id

Path

path to the device

A system-specific device path that indicates which device is behind this zwp_tablet_v2. This information may be used to gather additional information about the device, e.g. through libwacom.

A device may have more than one device path. If so, multiple zwp_tablet_v2.path events are sent. A device may be emulated and not have a device path, and in that case this event will not be sent.

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 zwp_tablet_v2.done event.

Fields

path: String

path to local device

Done

tablet description events sequence complete

This event is sent immediately to signal the end of the initial burst of descriptive events. A client may consider the static description of the tablet to be complete and finalize initialization of the tablet.

Removed

tablet removed event

Sent when the tablet has been removed from the system. When a tablet is removed, some tools may be removed.

When this event is received, the client must zwp_tablet_v2.destroy the object.

Bustype

tablet device bus type

The bustype argument is one of the BUS_ defines in the Linux kernel’s linux/input.h

If the device has no known bustype or the bustype cannot be queried, this event is not sent.

This event is sent in the initial burst of events before the zwp_tablet_v2.done event.

Only available since version 2 of the interface

Fields

bustype: WEnum<Bustype>

bus type
