Reopen окно с помощью PyGObject

Question

Код:

<...> 
class Handler: 
    <...> 
    @staticmethod 
    def about_destroy(*args): 
     about_win.destroy() 
    <...> 
    @staticmethod 
    def about_menu(*args): 
     about_win.show_all() 

builder = Gtk.Builder() 
builder.add_from_file("{}/gui.glade".format(SCRIPTDIR)) 
builder.connect_signals(Handler()) 

about_win = builder.get_object("About") 

main = builder.get_object("Main") 
main.show_all() 
<...> 
Gtk.main() 

Я пытаюсь вновь открыть окно, но получить: (gui.py:20607):

Gtk-ВАЖНЫЙ **: gtk_widget_show: утверждение 'GTK_IS_WIDGET (виджет)' не удалось

(gui.py:20607): Gtk-ВАЖНЫЙ **: gtk_label_set_markup: утверждение 'GTK_IS_LABEL (ярлык)' не удалось

(gui.py:20607): Gtk-ВАЖНЫЙ **: gtk_container_foreach: утверждение 'GTK_IS_CONTAINER (контейнер)' не удалось

Я решил мой проблема сама по себе.

Я использую .hide() метод вместо .destroy() в настоящее время. Мой код:

<...> 
class Handler: 
    <...> 
    @staticmethod 
    def about_destroy(*args): 
     about_win.hide() 
    <...> 
    @staticmethod 
    def about_menu(*args): 
     about_win.show_all() 

builder = Gtk.Builder() 
builder.add_from_file("{}/gui.glade".format(SCRIPTDIR)) 
builder.connect_signals(Handler()) 

about_win = builder.get_object("About") 

main = builder.get_object("Main") 
main.show_all() 
<...> 
Gtk.main()
