class EkdSaveDialog(QDialog):
'''
EkdSaveDialog : Classe représentant la boite de dialogue utiliser lors de
l'enregistrement des modification sur un fichier donné
attributs : suffix - Suffix utilisé en filtre
filter - Filtre (déduit à partir du suffix)
chemin - Chemin du dernier fichier enregistré
multiple - va-t-on enregistrer plus d'un fichier ?
(ex: extraction d'image d'une vidéo)
méthodes : getFile - Invoque la boite de dialogue et retourne
le fichier saisi
'''
### Pourquoi avoir réimplémenté cette classe au lieu de passer par
### QFileDialog ?
## Correction du bug de consommation mémoire
##
## Explication du problème :
## Par défaut un QFileDialog utilise un QFileSystemModel qui lui
## crée un QWatchFileSystem
## Hors QWatchFileSystem scan régulièrement les changement
## dans le répertoire courant
## Ce phénomène provoque une réaction en chaine :
## 1 - je choisi mon répertoire de destination d'enregistrement
## de mes images
## 2 - ffmpeg se lance
## 3 - ffmpeg crée un fichier dans l'arborescence
## 4 - QWatchFileSystem (est toujours dans le répertoire courant)
## détecte un changement
## et recharge l'ensemble du contenue du répertoire
## 5 - goto 3 jusqu'à plus de mémoire ou fin du process ffmpeg
##
