<description summary="protocol to configure output devices">
|
||||||
|
This protocol exposes interfaces to obtain and modify output device
|
||||||
|
configuration.
|
||||||
|
|
||||||
|
Warning! The protocol described in this file is experimental and
|
||||||
|
backward incompatible changes may be made. Backward compatible changes
|
||||||
|
may be added together with the corresponding interface version bump.
|
||||||
|
Backward incompatible changes are done by bumping the version number in
|
||||||
|
the protocol and interface names and resetting the interface version.
|
||||||
|
Once the protocol is to be declared stable, the 'z' prefix and the
|
||||||
|
version number in the protocol and interface names are removed and the
|
||||||
|
interface version number is reset.

<interface name="zwlr_output_manager_v1" version="4">
|
||||||
|
<description summary="output device configuration manager">
|
||||||
|
This interface is a manager that allows reading and writing the current
|
||||||
|
output device configuration.
|
||||||
|
|
||||||
|
Output devices that display pixels (e.g. a physical monitor or a virtual
|
||||||
|
output in a window) are represented as heads. Heads cannot be created nor
|
||||||
|
destroyed by the client, but they can be enabled or disabled and their
|
||||||
|
properties can be changed. Each head may have one or more available modes.
|
||||||
|
|
||||||
|
Whenever a head appears (e.g. a monitor is plugged in), it will be
|
||||||
|
advertised via the head event. Immediately after the output manager is
|
||||||
|
bound, all current heads are advertised.
|
||||||
|
|
||||||
|
Whenever a head's properties change, the relevant wlr_output_head events
|
||||||
|
will be sent. Not all head properties will be sent: only properties that
|
||||||
|
have changed need to.
|
||||||
|
|
||||||
|
Whenever a head disappears (e.g. a monitor is unplugged), a
|
||||||
|
wlr_output_head.finished event will be sent.
|
||||||
|
|
||||||
|
After one or more heads appear, change or disappear, the done event will
|
||||||
|
be sent. It carries a serial which can be used in a create_configuration
|
||||||
|
request to update heads properties.
|
||||||
|
|
||||||
|
The information obtained from this protocol should only be used for output
|
||||||
|
configuration purposes. This protocol is not designed to be a generic
|
||||||
|
output property advertisement protocol for regular clients. Instead,
|
||||||
|
protocols such as xdg-output should be used.

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.

<description summary="output device">
|
||||||
|
A head is an output device. The difference between a wl_output object and
|
||||||
|
a head is that heads are advertised even if they are turned off. A head
|
||||||
|
object only advertises properties and cannot be used directly to change
|
||||||
|
them.
|
||||||
|
|
||||||
|
A head has some read-only properties: modes, name, description and
|
||||||
|
physical_size. These cannot be changed by clients.
|
||||||
|
|
||||||
|
Other properties can be updated via a wlr_output_configuration object.
|
||||||
|
|
||||||
|
Properties sent via this interface are applied atomically via the
|
||||||
|
wlr_output_manager.done event. No guarantees are made regarding the order
|
||||||
|
in which properties are sent.

|

|
<description summary="head name">
|
||||||
|
This event describes the head name.
|
||||||
|
|
||||||
|
The naming convention is compositor defined, but limited to alphanumeric
|
||||||
|
characters and dashes (-). Each name is unique among all wlr_output_head
|
||||||
|
objects, but if a wlr_output_head object is destroyed the same name may
|
||||||
|
be reused later. The names will also remain consistent across sessions
|
||||||
|
with the same hardware and software configuration.
|
||||||
|
|
||||||
|
Examples of names include 'HDMI-A-1', 'WL-1', 'X11-1', etc. However, do
|
||||||
|
not assume that the name is a reflection of an underlying DRM
|
||||||
|
connector, X11 connection, etc.
|
||||||
|
|
||||||
|
If the compositor implements the xdg-output protocol and this head is
|
||||||
|
enabled, the xdg_output.name event must report the same name.
|
||||||
|
|
||||||
|
The name event is sent after a wlr_output_head object is created. This
|
||||||
|
event is only sent once per object, and the name does not change over
|
||||||
|
the lifetime of the wlr_output_head object.

This event describes a human-readable description of the head.

The description is a UTF-8 string with no convention defined for its
|
||||||
|
contents. Examples might include 'Foocorp 11" Display' or 'Virtual X11
|
||||||
|
output via :1'. However, do not assume that the name is a reflection of

|
the make, model, serial of the underlying DRM connector or the display
|
||||||
|
name of the underlying X11 connection, etc.

This object is used by the client to describe a full output configuration.

First, the client needs to setup the output configuration. Each head can

be either enabled (and configured) or disabled. It is a protocol error to

send two enable_head or disable_head requests with the same head. It is a

protocol error to omit a head in a configuration.

Then, the client can apply or test the configuration. The compositor will

then reply with a succeeded, failed or cancelled event. Finally the client
