egui-winit-ash-integration

This is the egui integration crate for egui-winit and ash. The default GPU allocator is gpu_allocator, but you can also implement AllocatorTrait.

Example

sh cargo run --example example

sh cargo run --example user_texture

Usage

```rust fn main() -> Result<()> { let eventloop = EventLoop::new(); // (1) Call Integration::>>::new() in App::new(). let mut app = App::new(&eventloop)?;

event_loop.run(move |event, _, control_flow| {
    *control_flow = ControlFlow::Poll;

    match event {
        Event::WindowEvent { event, window_id: _ } => {
            // (2) Call integration.handle_event(&event).
            let _response = app.egui_integration.handle_event(&event);
            match event {
                WindowEvent::Resized(_) => {
                    app.recreate_swapchain().unwrap();
                }
                WindowEvent::ScaleFactorChanged { .. } => {
                    // (3) Call integration.recreate_swapchain(...) in app.recreate_swapchain().
                    app.recreate_swapchain().unwrap();
                }
                WindowEvent::CloseRequested => {
                    *control_flow = ControlFlow::Exit;
                }
                _ => (),
            }
        },
        Event::MainEventsCleared => app.window.request_redraw(),
        Event::RedrawRequested(_window_id) => {
            // (4) Call integration.begin_frame(), integration.end_frame(&mut window),
            // integration.context().tessellate(shapes), integration.paint(...)
            // in app.draw().
            app.draw().unwrap();
        },
        _ => (),
    }
})

} // (5) Call integration.destroy() when drop app. ```
