<interface name="zwlr_workspace_manager_v1" version="1">
<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 zwlr_workspace_manager_v1, each workspace will be
sent via the workspace event.
</description>
<event name="workspace_group">
<description summary="a workspace group has been created">
This event is emitted whenever a new workspace group has been created.
All initial details of the workspace group (workspaces, outputs) will be
sent immediately after this event via the corresponding events in
zwlr_workspace_group_handle_v1.
</description>
<arg name="workspace_group" type="new_id" interface="zwlr_workspace_group_handle_v1"/>
</event>
<request name="commit">
<description summary="all requests about the workspaces have been sent">
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 zwlr_workspace_handle_v1 objects, for example, deactivating one
workspace and activating another.
</description>
</request>
<event name="done">
<description summary="all information about the workspace groups has been sent">
This event is sent after all changes in all workspace groups have been
sent.
This allows changes to one or more zwlr_workspace_group_handle_v1
properties 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
zwlr_workspace_group_handle_v1 objects in question. The compositor sends
the done event only after updating the output information in both
workspace groups.
</description>
</event>
<event name="finished">
<description summary="the compositor has finished with the workspace_manager">
This event indicates that the compositor is done sending events to the
zwlr_workspace_manager_v1. The server will destroy the object
immediately after sending this request, so it will become invalid and
the client should free any resources associated with it.
</description>
</event>
<request name="stop">
<description summary="stop sending events">
Indicates the client no longer wishes to receive events for new
workspace groups. However the compositor may emit further workspace
events, until the finished event is emitted.
The client must not send any more requests after this one.

A zwlr_workspace_group_handle_v1 object represents a a workspace group

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.

The compositor must remove all workspaces belonging to a workspace group
before removing the workspace group.

<interface name="zwlr_workspace_handle_v1" version="1">
<description summary="a workspace handing a group of surfaces">
A zwlr_workspace_handle_v1 object represents a a workspace that handles a
group of surfaces.
Each workspace has a name, conveyed to the client with the name 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.
</description>

This event is emitted immediately after the zwlr_workspace_handle_v1 is
created and whenever the name of the workspace changes.
</description>
<arg name="name" type="string"/>
</event>
<event name="coordinates">
<description summary="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 zwlr_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.
</description>
<arg name="coordinates" type="array"/>
</event>
<event name="state">
<description summary="the state of the workspace changed">
This event is emitted immediately after the zwlr_workspace_handle_v1 is

compositor action or because of a request in this protocol.
