GTK+3 的 Go 绑定 gotk3

gotk3 提供 Go 绑定 GTK+3 和依赖的其他项目。每个组件都给出了用来导入包路径的子目录。以下是部分已经实施的支持库：

* GTK+3 (3.6 and later)

* GDK 3 (3.6 and later)

* GLib 2 (2.36 and later)

* Cairo (1.10 and later)

已经采取谨慎的内存管理与Go的垃圾收集器无缝工作，而无需使用或理解图形对象的浮动参考。

简单示例：

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()
}
