Deno GI

Port of Gnome libraries (like Gtk) for Deno using gobject-introspection.

Early Stage and Unstable

Usage

Loading a library

Loading a library is done by calling require function.

Loading Gtk:

import * as gi from "https://deno.land/x/deno_gi/mod.js";
const Gtk = gi.require("Gtk", "4.0");

If you don’t explicitly define version, the latest version will be loaded

Creating Objects

Objects are initialized using creation functions or javascript constructors.

// creation function
const button = Gtk.Button.newWithLabel("Click Me!");

// js constructor
const button = new Gtk.Button({ label: "Click Me!" });

Signals

Signals are connected using on method.

button.on("clicked", () => {
  console.log("Clicked");
});

Example

import * as gi from "https://deno.land/x/deno_gi/mod.js";

const Gtk = gi.require("Gtk", "4.0");

const app = new Gtk.Application();

app.on("activate", () => {
  const win = new Gtk.ApplicationWindow({ app: application });
  const contentArea = new Gtk.Box();
  const label = new Gtk.Label({ label: "Hello World!" });

  contentArea.append(label);
  win.setChild(contentArea);
  win.present();
});

app.run();

Run the example with --allow-ffi and --unstable flags.
