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.

Title

title change

This event is emitted whenever the title of the toplevel changes.

Fields of Title

title: String

AppId

app-id change

This event is emitted whenever the app-id of the toplevel changes.

Fields of AppId

app_id: String

OutputEnter

toplevel entered an output

This event is emitted whenever the toplevel becomes visible on the given output. A toplevel may be visible on multiple outputs.

Fields of OutputEnter

output: WlOutput

OutputLeave

toplevel left an output

This event is emitted whenever the toplevel stops being visible on the given output. It is guaranteed that an entered-output event with the same output has been emitted before this event.

Fields of OutputLeave

output: WlOutput

State

the toplevel state changed

This event is emitted immediately after the zlw_foreign_toplevel_handle_v1 is created and each time the toplevel state changes, either because of a compositor action or because of a request in this protocol.

Fields of State

state: Vec<u8>

Done

all information about the toplevel has been sent

This event is sent after all changes in the toplevel state have been sent.

This allows changes to the zwlr_foreign_toplevel_handle_v1 properties to be seen as atomic, even if they happen via multiple events.

Closed

this toplevel has been destroyed

This event means the toplevel has been destroyed. It is guaranteed there won't be any more events for this zwlr_foreign_toplevel_handle_v1. The toplevel itself becomes inert so any requests will be ignored except the destroy request.
