<description summary="list and control workspaces">
|
||||||
|
Workspaces, also called virtual desktops, are groups of surfaces. A
|
||||||
|
compositor with a concept of workspaces may only show some such groups of
|
||||||
|
surfaces (those of 'active' workspaces) at a time. 'Activating' a
|
||||||
|
workspace is a request for the compositor to display that workspace's
|
||||||
|
surfaces as normal, whereas the compositor may hide or otherwise
|
||||||
|
de-emphasise surfaces that are associated only with 'inactive' workspaces.
|
||||||
|
Workspaces are grouped by which sets of outputs they correspond to, and
|
||||||
|
may contain surfaces only from those outputs. In this way, it is possible
|
||||||
|
for each output to have its own set of workspaces, or for all outputs (or
|
||||||
|
any other arbitrary grouping) to share workspaces. Compositors may
|
||||||
|
optionally conceptually arrange each group of workspaces in an
|
||||||
|
N-dimensional grid.
|
||||||
|
|
||||||
|
The purpose of this protocol is to enable the creation of taskbars and
|
||||||
|
docks by providing them with a list of workspaces and their properties,
|
||||||
|
and allowing them to activate and deactivate workspaces.
|
||||||
|
|
||||||
|
After a client binds the ext_workspace_manager_v1, each workspace will be
|
||||||
|
sent via the workspace event.

The client must send this request after it has finished sending other

requests. The compositor must process a series of requests preceding a

commit request atomically.
|
||||||
|
|

|
This allows changes to the workspace properties to be seen as atomic,
|

even if they happen via multiple events, and even if they involve
|
||||||
|
multiple ext_workspace_handle_v1 objects, for example, deactivating one

This event is sent after all changes in all workspaces and workspace groups have been

|
to be seen as atomic, even if they happen via multiple events.

In particular, an output moving from one workspace group to

another sends an output_enter event and an output_leave event to the two

<description summary="a workspace group assigned to a set of outputs">
|
||||||
|
A ext_workspace_group_handle_v1 object represents a workspace group
|
||||||
|
that is assigned a set of outputs and contains a number of workspaces.
|
||||||
|
|
||||||
|
The set of outputs assigned to the workspace group is conveyed to the client via
|
||||||
|
output_enter and output_leave events, and its workspaces are conveyed with
|
||||||
|
workspace events.
|
||||||
|
|
||||||
|
For example, a compositor which has a set of workspaces for each output may
|
||||||
|
advertise a workspace group (and its workspaces) per output, whereas a compositor
|
||||||
|
where a workspace spans all outputs may advertise a single workspace group for all
|
||||||
|
outputs.

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 creating workspaces, a button
|

|
triggering the create_workspace request should not be displayed.
|
||||||
|

The compositor will ignore requests it doesn't support. For instance,

a compositor which doesn't advertise support for creating workspaces will ignore

create_workspace requests.

|

A ext_workspace_handle_v1 object represents a workspace that handles a
|
||||||
|
group of surfaces.
|
||||||
|
|
||||||

Each workspace has:
|
||||||

- a name, conveyed to the client with the name event
|

|
- potentially an id conveyed with the id event
|
||||||
|
- a list of states, conveyed to the client with the state event

|
- and optionally a set of coordinates, conveyed to the client with the
|
||||||
|
coordinates event
|
||||||
|
|
||||||
|
The client may request that the compositor activate or deactivate the workspace.
|
||||||
|
|
||||||
|
Each workspace can belong to only a single workspace group.
|
||||||
|
Depepending on the compositor policy, there might be workspaces with
|
||||||
|
the same name in different workspace groups, but these workspaces are still
|

separate (e.g. one of them might be active while the other is not).

<description summary="workspace id">
|
||||||
|
If this event is emitted, it will be send immediately after the
|
||||||
|
ext_workspace_handle_v1 is created or when an id is assigned to
|
||||||
|
a workspace (at most once during it's lifetime).
|
||||||
|
|
||||||
|
An id will never change during the lifetime of the `ext_workspace_handle_v1`
|
||||||
|
and is guaranteed to be unique during it's lifetime.
|
||||||
|
|
||||||
|
Ids are not human-readable and shouldn't be displayed, use `name` for that purpose.
|
||||||
|
|
||||||
|
Compositors are expected to only send ids for workspaces likely stable across multiple
|
||||||
|
sessions and can be used by clients to store preferences for workspaces. Workspaces without
|
||||||
|
ids should be considered temporary and any data associated with them should be deleted once
|
||||||
|
the respective object is lost.

This event is used to organize workspaces into an N-dimensional grid
|
||||||
|
within a workspace group, and if supported, is emitted immediately after
|
||||||
|
the ext_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.

This event advertises the capabilities supported by the compositor. If

a compositor which doesn't advertise support for remove will ignore

remove requests.

Compositors must send this event once after creation of an
