Bonsoir,

Actuellement en train de commencer avec PyGTK j'ai un souci lorsque je clic sur mon menu Fichier>Ouvrir, ça ouvre bien la boite de dialogue de sélection d'un fichier, lorsque je clic sur la croix pour fermer la fenêtre ça ferme bien la fenêtre et lorsque je refais Fichier>Ouvrir mon programme se ferme (fenêtre principal du programme) et je ne vois pas du tout pourquoi ça fait ça.

Edit : Bon au final sur toute les fenêtre que je crée ça fait la même chose :/ J'ai erreur de segmentation dans l'interpréteur

Voila mon code :

glade :

Merci d'avance.

Bonsoir,

En fait c'est tout a fait normal que tu obtienne un segmentation fault puisque lors du clic sur la croix rouge tu détruit la fenêtre en question. Tu peux soit essayer d'écrire directement le code ( c'est pas bien long ) :

Deja on crée la fenetre "ouvrir" :

ouvrir = gtk.FileChooserDialog("Ouverture de fichiers", self.fenetre, gtk.FILE_CHOOSER_ACTION_OPEN, ((gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL, gtk.STOCK_OPEN, gtk.RESPONSE_OK)))

Ensuite il te faut une variable qui va contenire la réponse de l'utilisateur, c'est à dire si il ouvre un fichier ou tout simplement qu'il annule :

reponse = ouvrir.run()

Et la tu peut traiter les différents choix de la part de l'utilisateur :

if reponse == gtk.RESPONSE_OK:
    print "OK"
elif reponse == gtk.RESPONSE_CANCEL:
    print "CANCEL"

Une fois le traitement terminé il faut détruire la fenetre que tu as crée au risque d'en créer une a chaque ouverture de fichier :

ouvrir.destroy()

Et sinon en passant par pyGTK tu active ta fenêtre avec show() et tu la cache avec hide(). Par contre l'astuce viens du fait qu'il faut intercepter l’événement de destruction : "delete-event" et non le signal "destroy". Le delete-event correspond au moment entre lequel tu a clic la croix et la fenêtre qui va se détruire. Tu intercepte ce signal et au lieu de détruire la fenêtre tu la cache

Merci de ta réponse

Bah oui au final cet après midi j'ai réussi en écrivant le code

Donc pour utiliser le filechooserdialog avec glade il faut utiliser delete-event ?
Mais cacher la fenêtre avec hide ne consomme pas plus de ressource que de la détruire ?
Et j'ai essayé en utilisant pygobject qui est conseillé plutôt que pygtk (je ne sais pas pourquoi d'ailleurs :/) mais il y a certaines constantes qui ont changé apparament.

Voila mon nouveau code sinon (Et par la même occasion si tu pouvais me dire si mon code peut être optimisé et comment ? Bon il n'y a pas grand chose mais si je peux déjà "bien coder"):
