Struct X11Screen

pub struct X11Screen { /* private fields */ }

Signals

window-manager-changed

GLib type: GObject with reference counted clone semantics.

Implementations

impl X11Screen

pub fn current_desktop(&self) -> u32

Returns the current workspace for @self when running under a window manager that supports multiple workspaces, as described in the Extended Window Manager Hints specification.

Returns

the current workspace, or 0 if workspaces are not supported

pub fn number_of_desktops(&self) -> u32

Returns the number of workspaces for @self when running under a window manager that supports multiple workspaces, as described in the Extended Window Manager Hints specification.

Returns

the number of workspaces, or 0 if workspaces are not supported

pub fn screen_number(&self) -> i32

Returns the index of a X11Screen.

Returns

the position of @self among the screens of its display

pub fn window_manager_name(&self) -> GString

Returns the name of the window manager for @self.

Returns

the name of the window manager screen @self, or “unknown” if the window manager is unknown. The string is owned by GDK and should not be freed.

pub fn supports_net_wm_hint(&self, property_name: &str) -> bool

This function is specific to the X11 backend of GDK, and indicates whether the window manager supports a certain hint from the Extended Window Manager Hints specification.

When using this function, keep in mind that the window manager can change over time; so you shouldn’t use this function in a way that impacts persistent application state. A common bug is that your application can start up before the window manager does when the user logs in, and before the window manager starts gdk_x11_screen_supports_net_wm_hint() will return false for every property. You can monitor the window_manager_changed signal on X11Screen to detect a window manager change.

property_name

name of the WM property

Returns

true if the window manager supports @property

pub fn connect_window_manager_changed<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId

impl X11Screen

pub unsafe fn xscreen(&self) -> *mut Screen

Available on crate feature xlib only.

Returns the screen of a X11Screen.

Returns

an Xlib Screen*

pub fn monitor_output(&self, monitor_num: i32) -> XID

Gets the XID of the specified output/monitor. If the X server does not support version 1.2 of the RANDR extension, 0 is returned.

monitor_num

number of the monitor, between 0 and gdk_screen_get_n_monitors (screen)

Returns

the XID of the monitor

Trait Implementations

impl Clone for X11Screen

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for X11Screen

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

Formats the value using the given formatter.

impl HasParamSpec for X11Screen

type ParamSpec = ParamSpecObject

type SetValue = X11Screen

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

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, X11Screen>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for X11Screen

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

where H: Hasher,

Hashes the memory address of this object.

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 X11Screen

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

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

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,

Restrict a value to a certain interval.

impl ParentClassIs for X11Screen

type Parent = Object

impl<OT: ObjectType> PartialEq<OT> for X11Screen

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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

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

impl<OT: ObjectType> PartialOrd<OT> for X11Screen

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

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for X11Screen

fn static_type() -> Type

Returns the type identifier of Self.
