conseils pour une petite application graphique

Ave

J'ai écrit un petit programme graphique avec 3 boutons qui enrobe la récupération de vidéos de la BBC avec get_iplayer.

J'ai utilisé Tkinter, c'est moche et ça marche.

Que me conseillez-vous ?

Pyqt, WxPython...

Merci pour vos lumières/ idées d'amélioration

Si vous voulez tester, installez get_iplayer, rentrez par exemple
Wrong Mans
puis cliquer sur Film
cela va vous proposer les épisodes 1, 2, et 3
vous en sélectionnez un, puis cliquez sur download
et vous aurez une vidéo et un fichier de sous-titres, du même nom.

Re : conseils pour une petite application graphique

Salut,

je ne sais pas à quoi ressemble ton appli, mais si tu veux quelque chose qui ressemble à tes applis GTK, je te suggère gtkdialog ; pour voir à quoi ça ressemble côté visuel et côté code (dans du bash, en l'occurence) : http://puppy2.org/slaxer/Porteus/Gtkdia … color.html

Hoplà !

PS: tu bootes quoi sur clé USB dans ton Ebox ? Perso, j'ai mis un dur 2"5 dans le mien, ça ouvre pas mal de perspectives ! (bon, là mon dur est mort ...)

Re : conseils pour une petite application graphique

Je vais regarder GTKDialog, merci.

J'ai essayé plusieurs OS, j'ai préféré Toutou Linux (variante française de Puppy Linux).
Sinon DSL (Damn Small Linux) est très bien aussi.
