gotk3

Package gotk3 provides Go bindings for GLib 2, GDK 3, and GTK+3. Each component is given its own subdirectory, which is used as the import path for the package.

Care has been taken for memory management to work seamlessly with Go's garbage collector without the need to use or understand GObject's floating references.

Sample Use

The following example can be found in gtk/examples/simple/simple.go. Usage of additional features is also demonstrated in the gtk/examples/ directory.

package main

import (
	"github.com/conformal/gotk3/gtk"
	"log"
)

func main() {
	// Initialize GTK without parsing any command line arguments.
	gtk.Init(nil)

	// Create a new toplevel window, set its title, and connect it to the
	// "destroy" signal to exit the GTK main loop when it is destroyed.
	win, err := gtk.WindowNew(gtk.WINDOW_TOPLEVEL)
	if err != nil {
		log.Fatal("Unable to create window:", err)
	}
	win.SetTitle("Simple Example")
	win.Connect("destroy", func() {
		gtk.MainQuit()
	})

	// Create a new label widget to show in the window.
	l, err := gtk.LabelNew("Hello, gotk3!")
	if err != nil {
		log.Fatal("Unable to create label:", err)
	}

	// Add the label to the window.
	win.Add(l)

	// Set the default window size.
	win.SetDefaultSize(800, 600)

	// Recursively show all widgets contained in this window.
	win.ShowAll()

	// Begin executing the GTK main loop.  This blocks until
	// gtk.MainQuit() is run. 
	gtk.Main()
}

Documentation

Each package's internal go doc style documentation can be viewed online without installing this package by using the GoDoc site (links to glib, gdk, and gtk documentation).

You can also view the documentation locally once the package is installed with the godoc tool by running godoc -http=":6060" and pointing your browser to http://localhost:6060/pkg/github.com/conformal/gotk3

Installation

gotk3 currently requires GTK 3.8 and GLib 2.36 or later. Older GTK and GLib versions may work due to missing bindings, but installing on these older versions is not supported.

The gtk package requires glib and gdk packages as dependencies, so only one go get is necessary for complete installation.

$ go get github.com/conformal/gotk3/gtk

TODO

• Add bindings for all of GTK+
• Add tests for each implemented binding
• Add examples for intent

GPG Verification Key

All official release tags are signed by Conformal so users can ensure the code has not been tampered with and is coming from Conformal. To verify the signature perform the following:

• Download the public key from the Conformal website at https://opensource.conformal.com/GIT-GPG-KEY-conformal.txt

• Import the public key into your GPG keyring:

  gpg --import GIT-GPG-KEY-conformal.txt
  

• Verify the release tag with the following command where TAG_NAME is a placeholder for the specific tag:

  git tag -v TAG_NAME
