Struct wayland_protocols_wlr::gamma_control::v1::server::zwlr_gamma_control_v1::ZwlrGammaControlV1

pub struct ZwlrGammaControlV1 { /* private fields */ }

Available on crate feature server only.

adjust gamma tables for an output

This interface allows a client to adjust gamma tables for a particular output.

The client will receive the gamma size, and will then be able to set gamma tables. At any time the compositor can send a failed event indicating that this object is no longer valid.

There can only be at most one gamma control object per output, which has exclusive access to this particular output. When the gamma control object is destroyed, the gamma table is restored to its original value.

See also the Request enum for this interface.

Implementations

impl ZwlrGammaControlV1

pub fn gamma_size(&self, size: u32)

size of gamma ramps

Advertise the size of each gamma ramp.

This event is sent immediately when the gamma control object is created.

pub fn failed(&self)

object no longer valid

This event indicates that the gamma control is no longer valid. This can happen for a number of reasons, including:

• The output doesn’t support gamma tables
• Setting the gamma tables failed
• Another client already has exclusive gamma control for this output
• The compositor has transferred gamma control to another client

Upon receiving this event, the client should destroy this object.

Trait Implementations

impl Borrow<ObjectId> for ZwlrGammaControlV1

fn borrow(&self) -> &ObjectId

Immutably borrows from an owned value.

impl Clone for ZwlrGammaControlV1

fn clone(&self) -> ZwlrGammaControlV1

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ZwlrGammaControlV1

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ZwlrGammaControlV1

fn hash<H: Hasher>(&self, state: &mut H)

impl PartialEq<Weak<ZwlrGammaControlV1>> for ZwlrGammaControlV1

fn eq(&self, other: &Weak<ZwlrGammaControlV1>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

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

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