Golang MainQuit Examples

Example #1

func NewGTKUI() *GTKUI {
	gtk.Init(nil)
	window := gtk.Window(gtk.GTK_WINDOW_TOPLEVEL)
	window.SetPosition(gtk.GTK_WIN_POS_CENTER)
	window.SetTitle("Pond")
	window.SetDefaultSize(1000, 800)

	ui := &GTKUI{
		window:  window,
		actions: make(chan interface{}, uiActionsQueueLen),
		events:  make(chan interface{}, 8),
	}

		gtk.MainQuit()
	})
	if err := syscall.Pipe(ui.pipe[:]); err != nil {

	}
	syscall.SetNonblock(ui.pipe[0], true)

	glib.FdWatchAdd(ui.pipe[0], glib.IOIn, func(conditions int) bool {

	return ui
