Oui, le temps de démarrage était aussi pour moi une inconnue.
J'ai donc attaqué ces tests en premier, et je peux vous faire tester un premier script qui devrait vous rassurer sur la question.
Un point que j'avais oublié de préciser, ce n'est pas du GTK que je ne connait pas du tout c'est du Qt
Donc pour tester le script il faut PyQt. si vous ne l'avez pas encore, dans l'installateur de paquet que vous utilisez, cherchez python-qt4.
Copier le script ci-dessous dans un blocnote et enregistrez-le de préférence dans un nouveau dossier avec l'extension py.
Exemple : ~/newFolder/newArte7.py
Ensuite, lancer arte7Recorder, ne le fermez pas, aller dans votre dossier /tmp et copier le fichier database.
Coller-le en compagnie du script, c'est la raison du nouveau dossier.
Fermez arte7recorder, il n'a servit qu'à créer le fichier database.
lancez le script :
python newFolder/newArte7.py
Le script :

Il est normal que divers textes apparaissent dans la console, ils me servent à voir ce qui se passe "dans le moteur".
Pendant que les images se chargent testez déjà le drag and drop vers la fenêtre de droite pour vous convaincre que le chargement des image n'amène aucune contrainte de temps.
Les boutons et les menus ne sont pas encore "raccordés", et ne sont évidemment pas définitifs non plus.
@ plus
edit : Vous ne verrez pas les icônes sur les boutons, bien sur.
