When I run the thread example and try to move the window, it doesn't respond and the program is dead.

Please try to add runtime.LockOSThread() on the top of main func.

Thank you for your advice.I follow it, but it can not solve this issue.Any other advice? My code is as below:

package main

import (
	"runtime"
	"strconv"
	"time"

	"github.com/mattn/go-gtk/gdk"
	"github.com/mattn/go-gtk/glib"
	"github.com/mattn/go-gtk/gtk"
)

func main() {
	runtime.LockOSThread()
	runtime.GOMAXPROCS(10)
	glib.ThreadInit(nil)
	gdk.ThreadsInit()
	gdk.ThreadsEnter()
	gtk.Init(nil)
	window := gtk.NewWindow(gtk.WINDOW_TOPLEVEL)
	window.Connect("destroy", gtk.MainQuit)

	vbox := gtk.NewVBox(false, 1)

	label1 := gtk.NewLabel("")
	vbox.Add(label1)
	label2 := gtk.NewLabel("")
	vbox.Add(label2)

	window.Add(vbox)

	window.SetSizeRequest(800, 600)
	window.ShowAll()
	time.Sleep(1000 * 1000 * 100)
	go (func() {
		for i := 0; i < 30000000; i++ {
			gdk.ThreadsEnter()
			label1.SetLabel(strconv.Itoa(i))
			gdk.ThreadsLeave()
		}
		gtk.MainQuit()
	})()
	go (func() {
		for i := 30000000; i >= 0; i-- {
			gdk.ThreadsEnter()
			label2.SetLabel(strconv.Itoa(i))
			gdk.ThreadsLeave()
		}
		gtk.MainQuit()
	})()
	gtk.Main()
}
