[GTKBuilder]Nombreux warnings connect

[GTKBuilder]Nombreux warnings connect_signals

Bonjour,

Voila j'ai porté récemment une application de libglade (dépréciée) vers gtkbuilder.

Tout fonctionne à merveille, c'est parfait. Sauf un léger détail qui fait un peu "tache". Quand je lance le programme depuis une console j'ai un warning pour chaque signal de mon programme.

C'est légèrement agaçant, surtout que tout fonctionne sans problèmes :s

class SimpleGladeApp:
 
    def __init__(self, path, root=None, domain=None):
        self.glade_path = path
        self.builder = gtk.Builder()
        self.builder.set_translation_domain(domain)
        self.builder.add_from_file(path)
        self.builder.connect_signals(self)
        for o in self.builder.get_objects():
            if issubclass(type(o), gtk.Buildable):
                name = gtk.Buildable.get_name(o)
                setattr(self, name, o)
            else:
                pass
 
        if root:
            self.main_widget = self.get_widget(root)
        else:
            self.main_widget = None

Et :

class frmMain(SimpleGladeApp):
 
	def __init__(self, path="Main.glade", root="frmMain", domain="OpenShot", project=None, version="0.0.0", **kwargs):
		"""Init the main window"""
 
		# Load the Glade form using the SimpleGladeApp module	
		SimpleGladeApp.__init__(self, os.path.join(project.GLADE_DIR, path), root, domain, **kwargs)

Voila j'ai essayé pas mal de truc, je ne vois pas d'où ça vient, même après de nombreuses recherches sur google.

Salut,

L'erreur "missing handler" signifie que le Builder ne trouve pas de fonction callback.

Il faut que tu ajoutes la méthode "on_btnOK_clicked" (et les autres) dans ta classe "SimpleGladeApp" (la classe passée en argument de "builder.connect_signals" doit contenir les callbacks).

-

Mais l'intérêt de builder.connect_signals est de pouvoir connecter automatiquement les signaux normalement, si je commence à mettre tous les callbacks ça va vite devenir très lourd non ?

En fait avec libglade j'utilisais glade_xml_signal_autoconnect(xml) qui ne me renvoyait pas de warnings.

Surtout que le code fonctionne parfaitement sans !

Sans quoi ?

-

Les signaux sont bien connectés automatiquement à leur callback, mais il faut simplement spécifier où se trouvent ces fonctions callbacks.
Si tu passes "self" comme argument de la fonction "connect_signals", alors les fonctions callback doivent se trouver dans la classe désignée par "self".

Exemple :
Code:

1 2 3 4 5 6 7 8 9 class SimpleGladeApp: def __init__(self, path, root=None, domain=None): ... self.builder = gtk.Builder() ... self.builder.connect_signals(self) ... def on_btnOK_clicked(self, *data): print "Clic sur bouton OK"
Ensuite, il y a peut-être un problème dans la construction des classes : si par exemple c'est la classe fille "frmMain" qui contient les fonctions callback, alors ce n'est pas "self.builder.connect_signals(self)" qu'il faut appeler mais "self.builder.connect_signals(instance_de_la_classe_frmMain)"

J'espère avoir été clair... ;)

-

Merci beaucoup, c'est plus clair maintenant, je test ça des que j'ai le temps :D

Alors j'ai testé mais ça ne fonctionne pas.

Il faut savoir que toutes mes fenêtres héritent de la classe simplegladeapp.

J'ai essayé en virant simplegladeapp et en construisant le builder directement dans la classe ou se trouvent les callbacks mais j'ai toujours les warnings :s

Du coup je ne vois pas d'où ça peut venir :s

Pourrais-tu poster un bout de code qui affiche ces messages ?
(pas besoin de ton programme complet, juste un fichier glade avec un gtkbutton et son signal "clicked" + son code python (par exemple))

Eh bien curieusement pas de warning avec un programme plus simple construit de la même façon.

Je cherche ce que ca peut être.

A mon avis ça doit être parce que tu essaies de construire ton gtk.Builder avec des fonctions pas encore déclarées, ou un truc du genre. Faudrait voir au niveau des "import", ou dans l'ordre des de déclaration des fonctions/classes...
