分析主要代码
创建Gtk.ActionBar

ab = Gtk.ActionBar()

创建三个图片按钮，第一个放在最左边，第二个放在中间，第三个放在最末尾

icons = ["edit-cut", "edit-paste", "edit-copy"]theme = Gtk.IconTheme.get_default()for i, icon in enumerate(icons):    if theme.has_icon(icon):        image = Gtk.Image.new_from_icon_name(icon, Gtk.IconSize.MENU)        button = Gtk.Button()        button.add(image)        if i == 0:            ab.pack_start(button)        elif i == 1:            ab.set_center_widget(button)        elif i == 2:            ab.pack_end(button)
