gotk3

The gotk3 project provides Go bindings for GTK+3 and dependent projects. Each component is given its own subdirectory, which is used as the import path for the package. Partial binding support for the following libraries is currently implemented:

• GTK+3 (3.12 and later)
• GDK 3 (3.12 and later)
• GLib 2 (2.36 and later)
• Cairo (1.10 and later)

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 Examples.

package main

import (
	"github.com/gotk3/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()
}

To build the example:

$ go build example.go

To build this example with older gtk version you should use gtk_3_10 tag:

$ go build -tags gtk_3_10 example.go

Documentation

Each package's internal go doc style documentation can be viewed online without installing this package by using the GoDoc site (links to cairo, 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/gotk3/gotk3

Installation

gotk3 currently requires GTK 3.6-3.16, GLib 2.36-2.40, and Cairo 1.10 or 1.12. A recent Go (1.3 or newer) is also required.

For detailed instructions see the wiki pages: installation

TODO

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