libadwaita

Struct Application

source
pub struct Application { /* private fields */ }
Expand description

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

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.

Readable | Writeable

§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§

source§

impl Application

source

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

source

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.

source§

impl Application

source

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
