Struct libadwaita::Application

pub struct Application { /* private fields */ }

A base class for Adwaita applications.

Application handles library initialization by calling init() in the default startup signal handler, in turn chaining up as required by gtk::Application. Therefore, any subclass of Application should always chain up its startup handler before using any Adwaita or GTK API.

Automatic Resources

Application will automatically load stylesheets located in the application’s resource base path (see [ApplicationExtManual::set_resource_base_path()][crate::gio::prelude::ApplicationExtManual::set_resource_base_path()], if they’re present.

They can be used to add custom styles to the application, as follows:

• style.css contains styles that are always present.

• style-dark.css contains styles only used when dark is TRUE.

• style-hc.css contains styles used when the system high contrast preference is enabled.

• style-hc-dark.css contains styles used when the system high contrast preference is enabled and dark is TRUE.

Properties

style-manager

The style manager for this application.

This is a convenience property allowing to access StyleManager through property bindings or expressions.

Readable

Application

active-window

The currently focused window of the application.

Readable

menubar

The GMenuModel to be used for the application’s menu bar.

Readable | Writeable

register-session

Set this property to TRUE to register with the session manager.

This will make GTK track the session state (such as the screensaver-active property).

Readable | Writeable

screensaver-active

This property is TRUE if GTK believes that the screensaver is currently active.

GTK only tracks session state (including this) when register-session is set to true.

Tracking the screensaver state is currently only supported on Linux.

Readable

Application

action-group

The group of actions that the application exports.

Writeable

application-id

The unique identifier for the application.

Readable | Writeable | Construct

flags

Flags specifying the behaviour of the application.

Readable | Writeable

inactivity-timeout

Time (in milliseconds) to stay alive after becoming idle.

Readable | Writeable

is-busy

Whether the application is currently marked as busy through g_application_mark_busy() or g_application_bind_busy_property().

Readable

is-registered

Whether [ApplicationExtManual::register()][crate::gio::prelude::ApplicationExtManual::register()] has been called.

Readable

is-remote

Whether this application instance is remote.

Readable

resource-base-path

The base resource path for the application.

Readable | Writeable

version

The human-readable version number of the application.

Implements

AdwApplicationExt, gtk::prelude::ApplicationExt, gio::prelude::ApplicationExt, [trait@glib::ObjectExt], gio::prelude::ActionGroupExt, gio::prelude::ActionMapExt

GLib type: GObject with reference counted clone semantics.

Implementations

impl Application

pub const NONE: Option<&'static Application> = None

pub fn builder() -> ApplicationBuilder

Creates a new builder-pattern struct instance to construct Application objects.

This method returns an instance of ApplicationBuilder which can be used to create Application objects.

impl Application

pub fn new(application_id: Option<&str>, flags: ApplicationFlags) -> Self

Creates a new Application.

If application_id is not NULL, then it must be valid. See gio::Application::id_is_valid().

If no application ID is given then some features (most notably application uniqueness) will be disabled.

application_id

The application ID

flags

The application flags

Returns

the newly created Application

Trait Implementations

impl Clone for Application

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 Application

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

Formats the value using the given formatter.

impl Default for Application

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for Application

type ParamSpec = ParamSpecObject

type SetValue = Application

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Application

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<T: AdwApplicationImpl> IsSubclassable<T> for Application

fn class_init(class: &mut Class<Self>)

Override the virtual methods of this class for the given subclass and do other class initialization.

fn instance_init(instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for Application

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 + PartialOrd,

Restrict a value to a certain interval.

impl ParentClassIs for Application

type Parent = Application

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

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

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 Application

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

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 Application

fn static_type() -> Type

Returns the type identifier of Self.
