If this extension can be dropped after window creation.

fn as_any(&self) -> &dyn Any

fn as_any_mut(&mut self) -> &mut dyn Any

Cast to &mut dyn Any.

Provided Methods

fn configure(&mut self, args: &mut WindowConfigArgs<'_>)

Edit attributes for the new window.

fn window_inited(&mut self, args: &mut WindowInitedArgs<'_>)

Called just after the window is created.

fn command(&mut self, args: &mut WindowCommandArgs<'_>) -> ApiExtensionPayload

Called when a command request is made for the extension and window (window ID).

fn event(&mut self, args: &mut WindowEventArgs<'_>)
