Golang WidgetFromObject Examples

Example #1

File: builder.go Project: caengcjd/go-gtk

func main() {
	gtk.Init(&os.Args)
	builder := gtk.Builder()
	builder.AddFromFile("hello.ui")
	builder.ConnectSignals(nil)
	obj := builder.GetObject("window1")

	window := gtk.WidgetFromObject(obj)
	window.Show()
	window.Connect("destroy", gtk.MainQuit)

	gtk.Main()
}

Example #2

File: builder.go Project: mattn/go-gtk

//"github.com/mattn/go-gtk/example/builder/callback"
func main() {
	gtk.Init(&os.Args)

	builder := gtk.NewBuilder()

	builder.AddFromFile("hello.ui")
	obj := builder.GetObject("window1")

	window := gtk.WidgetFromObject(obj)
	window.Show()
	window.Connect("destroy", gtk.MainQuit)

	callback.Init(builder)

	gtk.Main()
}
