The behavior of a Cushy window.

Required Associated Types

type Context: Send + 'static

The type that is provided when initializing this window.

Required Methods

fn initialize( window: &mut RunningWindow<Window<'_, WindowCommand>>, context: Self::Context, ) -> Self

Return a new instance of this behavior using context.

fn make_root(&mut self) -> WidgetInstance

Create the window’s root widget. This function is only invoked once.

Provided Methods

fn initialized<W>(&mut self, window: &mut W)

where W: PlatformWindow,

Invoked once the window has been fully initialized.

fn close_requested<W>(&self, window: &mut W) -> bool

where W: PlatformWindow,

The window has been requested to close. If this function returns true, the window will be closed. Returning false prevents the window from closing.

fn run() -> Result

where Self::Context: Default,

Runs this behavior as an application.

fn run_with(context: Self::Context) -> Result

Runs this behavior as an application, initialized with context.

Object Safety

This trait is not object safe.
