代码解析
设置窗口默认图标

# set logo

icon = GdkPixbuf.Pixbuf.new_from_file(os.path.join(os.path.dirname(__file__), "../Data/gtk-logo-rgb.gif"))
# transparent

icon = icon.add_alpha(True, 0xff, 0xff, 0xff)
self.set_default_icon(icon)

hb = Gtk.HeaderBar()

创建Gtk.HeaderBar

hb.set_decoration_layout("icon,menu:minimize,maximize,close")

设置布局方式，名称中间用逗号分隔，冒号用来分隔左右两部分
最左边是图标（icon），中间是自定义的区域（menu），后面是最小化最大化和关闭按钮（minimize,maximize,close”），顺序可以任意调换

剩下一段代码主要讲解一下以下两句

box = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL)
Gtk.StyleContext.add_class(box.get_style_context(), "linked")

设置Box的样式为”linked”,这样，box中的子部件之间间距为0，而且子部件接触的地方没有圆角弧度之类的。
