Required Methods§
Provided Methods§
Sourcefn context_drawer(&self) -> Option<ContextDrawer<'_, Self::Message>>
fn context_drawer(&self) -> Option<ContextDrawer<'_, Self::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.
Sourcefn dialog(&self) -> Option<Element<'_, Self::Message>>
fn dialog(&self) -> Option<Element<'_, Self::Message>>
Displays a dialog in the center of the application window when Some
.
Displays a footer at the bottom of the application window when Some
.
Sourcefn header_start(&self) -> Vec<Element<'_, Self::Message>>
fn header_start(&self) -> Vec<Element<'_, Self::Message>>
Attaches elements to the start section of the header.
Sourcefn header_center(&self) -> Vec<Element<'_, Self::Message>>
fn header_center(&self) -> Vec<Element<'_, Self::Message>>
Attaches elements to the center of the header.
Sourcefn header_end(&self) -> Vec<Element<'_, Self::Message>>
fn header_end(&self) -> Vec<Element<'_, Self::Message>>
Attaches elements to the end section of the header.
Allows overriding the default nav bar widget.
Shows a context menu for the active nav bar item.
Allows COSMIC to integrate with your application’s nav_bar::Model
.
Sourcefn on_app_exit(&mut self) -> Option<Self::Message>
fn on_app_exit(&mut self) -> Option<Self::Message>
Called before closing the application. Returning a message will override closing windows.
Sourcefn on_close_requested(&self, id: Id) -> Option<Self::Message>
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<Self::Message>
Called when a navigation item is selected.
Called when a context menu is requested for a navigation item.
Sourcefn on_window_resize(&mut self, id: Id, width: f32, height: f32)
fn on_window_resize(&mut self, id: Id, width: f32, height: f32)
Called when a window is resized.
Sourcefn subscription(&self) -> Subscription<Self::Message>
fn subscription(&self) -> Subscription<Self::Message>
Event sources that are to be listened to.
Sourcefn update(&mut self, message: Self::Message) -> Task<Self::Message>
fn update(&mut self, message: Self::Message) -> Task<Self::Message>
Respond to an application-specific message.
Sourcefn system_theme_update(
&mut self,
keys: &[&'static str],
new_theme: &Theme,
) -> Task<Self::Message>
fn system_theme_update( &mut self, keys: &[&'static str], new_theme: &Theme, ) -> Task<Self::Message>
Respond to a system theme change
Sourcefn system_theme_mode_update(
&mut self,
keys: &[&'static str],
new_theme: &ThemeMode,
) -> Task<Self::Message>
fn system_theme_mode_update( &mut self, keys: &[&'static str], new_theme: &ThemeMode, ) -> Task<Self::Message>
Respond to a system theme mode change
Sourcefn view_window(&self, id: Id) -> Element<'_, Self::Message>
fn view_window(&self, id: Id) -> Element<'_, Self::Message>
Constructs views for other windows.
Sourcefn style(&self) -> Option<Appearance>
fn style(&self) -> Option<Appearance>
Overrides the default style for applications
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
