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

Fields

name: String

tablet device name

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

Id

Fields

vid: u32

pid: u32

tablet device USB vendor/product id

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

Path

Fields

path: String

path to the device

A system-specific device path that indicates which device is behind this wp_tablet. 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 wp_tablet.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 wp_tablet.done event.

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 wp_tablet.destroy the object.
