Module winit_030

Available on crate feature unstable-winit-030 only.

Expand description

Winit 0.30.x specific types and re-exports.

Note: This module is behind a feature flag and may be removed or changed in future minor releases, as new major Winit releases become available.

Use the types and traits in this module in combination with other APIs to access additional window properties, create custom windows, or hook into the winit event loop.

For example, use the WinitWindowAccessor to obtain access to the underling [winit::window::Window]:

Cargo.toml:

slint = { version = "~1.12", features = ["unstable-winit-030"] }

main.rs:

// Bring winit and accessor traits into scope.
use slint::winit_030::{WinitWindowAccessor, winit};

slint::slint!{
    import { VerticalBox, Button } from "std-widgets.slint";
    export component HelloWorld inherits Window {
        callback clicked;
        VerticalBox {
            Text {
                text: "hello world";
                color: green;
            }
            Button {
                text: "Click me";
                clicked => { root.clicked(); }
            }
        }
    }
}
fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Make sure the winit backed is selected:
   slint::BackendSelector::new()
       .backend_name("winit".into())
       .select()?;

    let app = HelloWorld::new()?;
    let app_weak = app.as_weak();
    app.on_clicked(move || {
        // access the winit window
        let app = app_weak.unwrap();
        app.window().with_winit_window(|winit_window: &winit::window::Window| {
            eprintln!("window id = {:#?}", winit_window.id());
        });
    });
    app.run()?;
    Ok(())
}

Re-exports§

pub use i_slint_backend_winit::winit;

Structs§

SlintEvent: Internal type used by the winit backend for thread communication and window system updates.

Enums§

WinitWindowEventResult: Returned by callbacks passed to Window::on_winit_window_event to determine if winit events should propagate to the Slint event loop.

Traits§

WinitWindowAccessor: This helper trait can be used to obtain access to the [winit::window::Window] for a given slint::Window.
