Bare bone Rust + GTK 4 app ๐Ÿ”—

You can get gtk-rs examples here . Just pick one of those examples and edit it and iterate over it to reach your desired application look and feel.

Here is a little GTK 4 example in Rust ๐Ÿ”—

use gtk::prelude::*;

fn main() {
    let application =
        gtk::Application::new(Some("com.github.gtk-rs.examples.basic"), Default::default());

fn build_ui(application: &gtk::Application) {
    let window = gtk::ApplicationWindow::new(application);

    window.set_title(Some("First GTK Program"));
    window.set_default_size(350, 70);

    let button = gtk::Button::with_label("Click me!");


Use this command to run this little program:

cargo run
