Window extension methods for HeadlessApp.

Required Methods

fn open_window<F>( &mut self, window_id: impl Into<WindowId>, new_window: impl IntoFuture<IntoFuture = F>, ) -> WindowVars

where F: Future<Output = WindowRoot> + Send + 'static,

Open a new headless window and returns the new window ID.

The new_window runs inside the WINDOW context of the new window.

Returns the WindowVars of the new window after the window is open and loaded.

fn focus_window(&mut self, window_id: impl Into<WindowId>)

Cause the headless window to think it is focused in the screen.

fn blur_window(&mut self, window_id: impl Into<WindowId>)

Cause the headless window to think focus moved away from it.

fn window_frame_image( &mut self, window_id: impl Into<WindowId>, mask: Option<ImageMaskMode>, ) -> ImageVar

Copy the current frame pixels of the window.

The var will update until the image is loaded or error.

fn close_window(&mut self, window_id: impl Into<WindowId>) -> bool

Sends a close request.

Returns if the window was found and closed.

fn run_window<F>( &mut self, window_id: impl Into<WindowId>, new_window: impl IntoFuture<IntoFuture = F>, )

where F: Send + Future<Output = WindowRoot> + 'static,

Open a new headless window and update the app until the window closes.

fn doc_test_window<F>(&mut self, new_window: impl IntoFuture<IntoFuture = F>)

where F: Future<Output = WindowRoot> + 'static + Send,

Open a new headless window and update the app until the window closes or 60 seconds elapse.

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.
