GTK and Rust
About
The gtk-rs project contains Rust bindings for GTK, Cairo and other GLib-compatible libraries.
The bindings of Cairo, Pango, Gio, Graphene and GLib are part of gtk-rs core. The bindings of GTK 4 can be found at gtk4-rs.
gtk-rs Documentation
gtk4-rs provides extensive documentation for its API based on GObject-Introspection. An introduction to building GUI applications with Rust and GTK 4 is also available in the form of a book.
The gtk4-rs Github repository features additional examples which demonstrate solutions to specific problems.
A Hello World app
This code shows how to use gtk4-rs to create a simple Hello World application.
use glib::clone;
// glib and other dependencies are re-exported by the gtk crate
use gtk::glib;
use gtk::prelude::*;
// When the application is launched…
fn on_activate(application: >k::Application) {
// … create a new window …
let window = gtk::ApplicationWindow::new(application);
// … with a button in it …
let button = gtk::Button::with_label("Hello World!");
// … which closes the window when clicked
button.connect_clicked(clone!(@weak window => move |_| window.close()));
window.set_child(Some(&button));
window.present();
}
fn main() {
// Create a new application with the builder pattern
let app = gtk::Application::builder()
.application_id("com.github.gtk-rs.examples.basic")
.build();
app.connect_activate(on_activate);
// Run the application
app.run();
}
