Open a native window in Rust

Run before editing

Run the prebuilt program from the Rust SDK root. Confirm the native window and HTML heading, then open examples/hello_world.rs.

.\bin\kui_rust_hello_world.exe

Read the complete entry point

Platform::init prepares the runtime, Window::new creates the window, document.load_html sends HTML to KUI, and platform.run starts the event loop. This example uses no WebView or JavaScript runtime.

use kui::{Platform, Window, WindowProps};

fn main() -> kui::Result<()> {
    let platform = Platform::init()?;
    let window = Window::new(&WindowProps {
        title: "KUI Rust SDK".into(),
        width: 960,
        height: 640,
        ..WindowProps::default()
    })?;
    let mut document = window.document()?;
    document.load_html(
        r#"<main style="padding:48px;font-family:sans-serif"><h1>Rust SDK 已接入 KUI</h1><p>此程序仅通过公开 C ABI 工作。</p></main>"#,
    )?;
    window.show()?;
    let _ = platform.run()?;
    Ok(())
}

Build this example only

Change the HTML heading. KUI_C_SDK points the build script to the import library; PATH lets the executable find native DLLs for this terminal session. Only this example is built.

$env:KUI_C_SDK = (Resolve-Path .\native).Path
$env:PATH = "$env:KUI_C_SDK\bin;$env:PATH"
cargo run --release --example hello_world

Check the result

Check the new heading. For linker errors, inspect native/lib/kui_c.lib; for launch errors, inspect native/bin and PATH. Keep UI objects on their creating thread and do not let panics cross the C ABI.
