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

workspace name changed

This event is emitted immediately after the zcosmic_workspace_handle_v1 is created and whenever the name of the workspace changes.

Fields

name: String

Coordinates

workspace coordinates changed

This event is used to organize workspaces into an N-dimensional grid within a workspace group, and if supported, is emitted immediately after the zcosmic_workspace_handle_v1 is created and whenever the coordinates of the workspace change. Compositors may not send this event if they do not conceptually arrange workspaces in this way. If compositors simply number workspaces, without any geometric interpretation, they may send 1D coordinates, which clients should not interpret as implying any geometry. Sending an empty array means that the compositor no longer orders the workspace geometrically.

Coordinates have an arbitrary number of dimensions N with an uint32 position along each dimension. By convention if N > 1, the first dimension is X, the second Y, the third Z, and so on. The compositor may chose to utilize these events for a more novel workspace layout convention, however. No guarantee is made about the grid being filled or bounded; there may be a workspace at coordinate 1 and another at coordinate 1000 and none in between. Within a workspace group, however, workspaces must have unique coordinates of equal dimensionality.

Fields

coordinates: Vec<u8>

State

the state of the workspace changed

This event is emitted immediately after the zcosmic_workspace_handle_v1 is created and each time the workspace state changes, either because of a compositor action or because of a request in this protocol.

Fields

state: Vec<u8>

Capabilities

compositor capabilities

This event advertises the capabilities supported by the compositor. If a capability isn’t supported, clients should hide or disable the UI elements that expose this functionality. For instance, if the compositor doesn’t advertise support for removing workspaces, a button triggering the remove request should not be displayed.

The compositor will ignore requests it doesn’t support. For instance, a compositor which doesn’t advertise support for remove will ignore remove requests.

Compositors must send this event once after creation of an zcosmic_workspace_handle_v1 . When the capabilities change, compositors must send this event again.

The capabilities are sent as an array of 32-bit unsigned integers in native endianness.

Fields

capabilities: Vec<u8>

array of 32-bit capabilities

Remove

this workspace has been destroyed

This event means the zcosmic_workspace_handle_v1 has been destroyed. It is guaranteed there won’t be any more events for this zcosmic_workspace_handle_v1. The zext_workspace_handle_v1 becomes inert so any requests will be ignored except the destroy request.

TilingState

indicates if tiling behavior is enabled for this workspace

This event is emitted immediately after the zcosmic_workspace_handle_v1 is created and each time the workspace tiling state changes, either because of a compositor action or because of a request in this protocol.

Only available since version 2 of the interface

Fields

state: WEnum<TilingState>
