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
