Code resolution
Set window default icon

# 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 ()

Create Gtk.headerbar

Hb.set_decoration_layout ("Icon,menu:minimize,maximize,close")

Set the layout by separating the names with commas and colons to separate the left and right parts
On the left is the icon, the middle is a custom area (menu), followed by the minimized Maximize and Close button (minimize,maximize,close "), the order can be changed arbitrarily

The remaining piece of code mainly explains the following two sentences

box = Gtk.box (orientation=gtk.orientation.horizontal)
Gtk.StyleContext.add_class (Box.get_style_context (), " Linked ")

The box is styled "linked" so that the child parts in box are spaced between 0 and the child parts are not in contact with fillet radians.
