Le "widget" de notification d'application est un mélange de widgets, d'une classe css et de comportements.
Vous devez utiliser un Gtk.Overlay dans la fenêtre que vous prévoyez d'utiliser les notifications d'application, puis utiliser un Gtk.Frame avec la classe app-notification
prédéfinie. Le Gtk.Frame doit être enveloppé dans un Gtk.Revealer pour permettre la transition "slide".
Voici un fichier ui Glade (app-notification.ui) avec un exemple:

Le résultat Glade:
Et voici un code python qui utilise le fichier glade précédent et donne un certain comportement dynamique à la notification afin que vous puissiez le voir en action en cliquant sur les boutons. Le fichier doit être nommé Glade app-notification.ui, sinon changer le code pour refléter le nom donné:
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
def onButtonShow(self):
revealer.set_reveal_child(True)
def onButtonClose(self):
revealer.set_reveal_child(False)
builder = Gtk.Builder()
builder.add_from_file("app-notification.ui")
window = builder.get_object("window1")
buttonShow = builder.get_object("button1")
buttonClose = builder.get_object ("button2")
revealer = builder.get_object("revealer2")
buttonShow.connect ("clicked", onButtonShow)
buttonClose.connect ("clicked", onButtonClose)
window.connect ("destroy", Gtk.main_quit)
window.show_all()
Gtk.main()
Je voudrais utiliser moi-même :) J'ai donc pris la liberté de faire rapport aucune référence API pour le lien au bas de la page. – theGtknerd
J'ai déjà envoyé un mail aujourd'hui, peut-être que ça ne prendra pas trop de temps :) – microo8
microo8 @theGtknerd cochez la réponse. –
