Struct epi::Frame

pub struct Frame<'a>(_);

Represents the surroundings of your app.

It provides methods to inspect the surroundings (are we on the web?), allocate textures, do http requests, and change settings (e.g. window size).

Implementations

impl<'a> Frame<'a>

pub fn is_web(&self) -> bool

True if you are in a web environment.

pub fn info(&self) -> &IntegrationInfo

Information about the integration.

pub fn tex_allocator(&mut self) -> &mut dyn TextureAllocator

A way to allocate textures.

pub fn quit(&mut self)

Signal the app to stop/exit/quit the app (only works for native apps, not web apps). The framework will not quit immediately, but at the end of the this frame.

pub fn set_window_size(&mut self, size: Vec2)

Set the desired inner size of the window (in egui points).

pub fn repaint_signal(&self) -> Arc<dyn RepaintSignal>

If you need to request a repaint from another thread, clone this and send it to that other thread.

pub fn http_fetch(
    &self,
    request: Request,
    on_done: impl 'static + Send + FnOnce(Result<Response, Error>)
)

Very simple Http fetch API. Calls the given callback when done.

You must enable the “http” feature for this.
