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.

Head

introduce a new head

This event introduces a new head. This happens whenever a new head appears (e.g. a monitor is plugged in) or after the output manager is bound.

Fields of Head

head: Main<ZwlrOutputHeadV1>

Done

sent all information about current configuration

This event is sent after all information has been sent after binding to the output manager object and after any subsequent changes. This applies to child head and mode objects as well. In other words, this event is sent whenever a head or mode is created or destroyed and whenever one of their properties has been changed. Not all state is re-sent each time the current configuration changes: only the actual changes are sent.

This allows changes to the output configuration to be seen as atomic, even if they happen via multiple events.

A serial is sent to be used in a future create_configuration request.

Fields of Done

serial: u32

Finished

the compositor has finished with the manager

This event indicates that the compositor is done sending manager events. The compositor will destroy the object immediately after sending this event, so it will become invalid and the client should release any resources associated with it.
