Struct gdk4_wayland::WaylandDisplay

pub struct WaylandDisplay { /* private fields */ }

The Wayland implementation of gdk::Display.

Beyond the regular gdk::Display API, the Wayland implementation provides access to Wayland objects such as the wl_display with wl_display(), the wl_compositor with wl_compositor().

You can find out what Wayland globals are supported by a display with query_registry().

Implements

gdk::prelude::DisplayExt

Implementations

impl WaylandDisplay

pub fn startup_notification_id(&self) -> Option<GString>

👎Deprecated: Since 4.10

Gets the startup notification ID for a Wayland display, or None if no ID has been defined.

Deprecated since 4.10

Returns

the startup notification ID for @self

pub fn query_registry(&self, global: &str) -> bool

Returns true if the interface was found in the display wl_registry.global handler.

global

global interface to query in the registry

Returns

true if the global is offered by the compositor

pub fn set_cursor_theme(&self, name: &str, size: i32)

Sets the cursor theme for the given @self.

name

the new cursor theme

size

the size to use for cursors

pub fn set_startup_notification_id(&self, startup_id: &str)

👎Deprecated: Since 4.10

Sets the startup notification ID for a display.

This is usually taken from the value of the DESKTOP_STARTUP_ID environment variable, but in some cases (such as the application not being launched using exec()) it can come from other sources.

The startup ID is also what is used to signal that the startup is complete (for example, when opening a window or when calling Gdk::Display::notify_startup_complete()).

Deprecated since 4.10

Use [ToplevelExtManual::set_startup_id()][crate::gdk::prelude::ToplevelExtManual::set_startup_id()]

startup_id

the startup notification ID (must be valid utf8)

impl WaylandDisplay

pub fn egl_display(&self) -> Option<Display>

Available on crate features v4_4 and egl only.

Retrieves the EGL display connection object for the given GDK display.

Returns

the EGL display

pub fn wl_compositor(&self) -> Option<WlCompositor>

Available on crate feature wayland_crate only.

Returns the Wayland wl_compositor of a gdk::Display.

Returns

a Wayland wl_compositor

pub fn wl_display(&self) -> Option<WlDisplay>

Available on crate feature wayland_crate only.

Returns the Wayland wl_display of a gdk::Display.

Returns

a Wayland wl_display

Trait Implementations

impl Clone for WaylandDisplay

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WaylandDisplay

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

Formats the value using the given formatter.

impl HasParamSpec for WaylandDisplay

type ParamSpec = ParamSpecObject

type SetValue = WaylandDisplay

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, WaylandDisplay>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for WaylandDisplay

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

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for WaylandDisplay

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl ParentClassIs for WaylandDisplay

type Parent = Display

impl<OT: ObjectType> PartialEq<OT> for WaylandDisplay

fn eq(&self, other: &OT) -> 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.

impl<OT: ObjectType> PartialOrd<OT> for WaylandDisplay

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for WaylandDisplay

fn static_type() -> Type

Returns the type identifier of Self.
