Struct ZwlrOutputConfigurationV1

pub struct ZwlrOutputConfigurationV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

output configuration

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 should destroy the configuration object.

See also the Event enum for this interface.

Implementations

impl ZwlrOutputConfigurationV1

pub fn enable_head<U, D>( &self, head: &ZwlrOutputHeadV1, qh: &QueueHandle<D>, udata: U, ) -> ZwlrOutputConfigurationHeadV1

where U: Send + Sync + 'static, D: Dispatch<ZwlrOutputConfigurationHeadV1, U> + 'static,

enable and configure a head

Enable a head. This request creates a head configuration object that can be used to change the head’s properties.

pub fn disable_head(&self, head: &ZwlrOutputHeadV1)

disable a head

Disable a head.

pub fn apply(&self)

apply the configuration

Apply the new output configuration.

In case the configuration is successfully applied, there is no guarantee that the new output state matches completely the requested configuration. For instance, a compositor might round the scale if it doesn’t support fractional scaling.

After this request has been sent, the compositor must respond with an succeeded, failed or cancelled event. Sending a request that isn’t the destructor is a protocol error.

pub fn test(&self)

test the configuration

Test the new output configuration. The configuration won’t be applied, but will only be validated.

Even if the compositor succeeds to test a configuration, applying it may fail.

After this request has been sent, the compositor must respond with an succeeded, failed or cancelled event. Sending a request that isn’t the destructor is a protocol error.

pub fn destroy(&self)

destroy the output configuration

Using this request a client can tell the compositor that it is not going to use the configuration object anymore. Any changes to the outputs that have not been applied will be discarded.

This request also destroys wlr_output_configuration_head objects created via this object.

impl PartialEq<Weak<ZwlrOutputConfigurationV1>> for ZwlrOutputConfigurationV1

fn eq(&self, other: &Weak<ZwlrOutputConfigurationV1>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
