Trait Implementations

impl Application for App

Implement [Application] to integrate with COSMIC.

const APP_ID: &'static str = "com.system76.CosmicFilesDialog"

The unique application ID to supply to the window manager.

type Executor = Executor

Default async executor to use with the app.

type Flags = Flags

Argument received

type Message = Message

Message type specific to our App.

fn init(core: Core, flags: Self::Flags) -> (Self, Task<Message>)

Creates the application, and optionally emits command on initialize.

fn update(&mut self, message: Message) -> Task<Message>

Handle application events here.

fn view(&self) -> Element<'_, Message>

Creates a view after each update.

fn core(&self) -> &Core

Grants access to the COSMIC Core.

fn core_mut(&mut self) -> &mut Core

Grants access to the COSMIC Core.

fn context_drawer(&self) -> Option<ContextDrawer<'_, Message>>

Displays a context drawer on the side of the application window when Some. Use the [ApplicationExt::set_show_context] function for this to take effect.

fn dialog(&self) -> Option<Element<'_, Message>>

Displays a dialog in the center of the application window when Some.

fn footer(&self) -> Option<Element<'_, Message>>

Displays a footer at the bottom of the application window when Some.

fn header_end(&self) -> Vec<Element<'_, Message>>

Attaches elements to the end section of the header.

fn nav_bar(&self) -> Option<Element<'_, Action<Self::Message>>>

Allows overriding the default nav bar widget.

fn nav_model(&self) -> Option<&SingleSelectModel>

Allows COSMIC to integrate with your application’s [nav_bar::Model].

fn on_app_exit(&mut self) -> Option<Message>

Called before closing the application. Returning a message will override closing windows.

fn on_nav_select(&mut self, entity: Entity) -> Task<Message>

Called when a navigation item is selected.

fn on_escape(&mut self) -> Task<Message>

Called when the escape key is pressed.

fn subscription(&self) -> Subscription<Message>

Event sources that are to be listened to.

fn header_start(&self) -> Vec<Element<'_, Self::Message, Theme, Renderer>>

Attaches elements to the start section of the header.

fn header_center(&self) -> Vec<Element<'_, Self::Message, Theme, Renderer>>

Attaches elements to the center of the header.

fn nav_context_menu( &self, id: Entity, ) -> Option<Vec<MenuTree<Action<Self::Message>>>>

Shows a context menu for the active nav bar item.

fn on_close_requested(&self, id: Id) -> Option<Self::Message>

Called when a window requests to be closed.

fn on_context_drawer(&mut self) -> Task<Action<Self::Message>>

fn on_nav_context(&mut self, id: Entity) -> Task<Action<Self::Message>>

Called when a context menu is requested for a navigation item.

fn on_search(&mut self) -> Task<Action<Self::Message>>

Called when the search function is requested.

fn on_window_resize(&mut self, id: Id, width: f32, height: f32)

Called when a window is resized.

fn system_theme_update( &mut self, keys: &[&'static str], new_theme: &Theme, ) -> Task<Action<Self::Message>>

Respond to a system theme change

fn system_theme_mode_update( &mut self, keys: &[&'static str], new_theme: &ThemeMode, ) -> Task<Action<Self::Message>>

Respond to a system theme mode change

fn view_window(&self, id: Id) -> Element<'_, Self::Message, Theme, Renderer>

Constructs views for other windows.

fn style(&self) -> Option<Style>

Overrides the default style for applications
