代码解析

stack = Gtk.Stack()
        stack.set_transition_type(Gtk.StackTransitionType.SLIDE_UP_DOWN)
stack.set_transition_duration(1000)

创建一个Gtk.Stack,设置动画时间1S，动画类型，上下切换

checkbutton = Gtk.CheckButton("Click me!")
stack.add_titled(checkbutton, "check", "Check Button")

label = Gtk.Label()
label.set_markup("<big>A fancy label</big>")
stack.add_titled(label, "label", "A label")

image = Gtk.Image.new_from_icon_name("help-about", Gtk.IconSize.MENU)
image.set_pixel_size(256)
stack.add_titled(image, "image", "Image")

向stack中添加三个子部件。

stacksidebar = Gtk.StackSidebar()
