<description summary="protocol to configure output devices">
|
||||
This protocol exposes interfaces to get and change 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.

|

<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, but they can be enabled or disabled and their properties can be
|
||||
changed. Each head may have one or more available modes.
|
||||
|
||||
Heads are advertised when the output manager is bound, and whenever they
|
||||
appear.
|
||||
|
||||
Whenever the number of heads or modes changes, the done event will be
|
||||
sent. It carries a serial which can be used in a create_configuration
|
||||
request to change 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.

<description summary="output device">
|
||||
A head is an output device. The difference with wl_output is that heads
|
||||
are advertized even if they are turned off. A head object only advertises
|
||||
properties and cannot be used directly to change them. In order to update
|
||||
some properties, one needs to create a wlr_output_configuration object.
|
||||
|
||||
A head has some read-only properties: mode, name, description and
|
||||
physical_size. These cannot be changed by clients.
|
||||
|
||||
enabled and current_mode are physical properties. Updating them might take
|
||||
some time, depending on hardware limitations.
|
||||
|
||||
position, transform and scale are logical properties. They describe how
|
||||
the output is mapped in the global compositor space.

|

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
