创建第一个Gtk.MenuButton,设置距离容器顶部50

button = Gtk.MenuButton("Menu Button popover")button.props.margin_top = 50

设置在button上方弹出气泡

button.set_direction(Gtk.ArrowType.UP)

创建一个Gtk.Popover(气泡窗口)

popover = self.create_popover(button, Gtk.Label("show popover"), Gtk.PositionType.TOP)@staticmethoddef create_popover(parent, child, pos):    popover = Gtk.Popover(relative_to=parent)    popover.set_position(pos)    popover.add(child)    popover.set_border_width(6)    child.show()    return popover

设置MenuButton点击时弹出这个popover

button.set_popover(popover)

创建第二个Gtk.MenuButton

button = Gtk.MenuButton("Menu Button popup")

创建一个Gtk.Menu（菜单）

menu = Gtk.Menu.new()for item in items:    item = Gtk.MenuItem(label=item)    item.connect("activate", self.on_menu_selected)    item.show()    menu.append(item)

绑定每一个菜单项“activate”信号，点击时执行on_menu_selected方法

@staticmethoddef on_menu_selected(widget, *args):    print("Menu item " + widget.get_label() + " was selected")

设置MenuButton点击时弹出这个菜单

button.set_popup(menu)
