go 与 gtk 的示例

cat main.go 

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(1920, 1080)
    //win.Move(100,100)

    // 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()
}
