Incular Docs

TitleController owns title state shared by rebuilds and the native bridge; Title binds it to a subtree with an optional sink.

use incular::prelude::*;

fn main() {
    let controller =
        TitleController::try_new("Incular", Color::BLACK).expect("opaque color");
    println!("accepted: {}", controller.set_title("New title"));
    println!(
        "color accepted: {}",
        controller.set_color(Color::BLACK).expect("opaque color")
    );
    println!(
        "set both: {}",
        controller
            .set("Title", Color::BLACK)
            .expect("opaque color")
    );
    println!("title: {}", controller.data().title);
    controller.synchronize();
    let app = Application::new(|_cx| {
        Title::simple("Incular", Text::new("Hi")).into()
    })
    .expect("valid application");
    incular::run(app).expect("run application");
}

TitleData { title: String, color: Color }. TitleError::TransparentColor (title colors must be opaque). WindowChromeSink trait: set_title(&str) -> bool, set_application_color(Color) -> bool (default false); NoopWindowChromeSink declines everything (headless).
