### GENERAL NOTES ###
|
| 5 |
"""
|
| 6 |
- voir si il faut gerer une demande de connexion alors que c'est deja connecte |
| 7 |
- voir si le bouton "cancel" est necesaire dans la fenetre "contacting" : |
| 8 |
- si oui il faudra trouver un moyen de faire la connection sans bloquer l'interface |
| 9 |
(thread, idle gtk ou io_watch?) |
| 10 |
- en prod regler test a 0 |
| 11 |
- bug pour setter le bouton par defaut quand on change de tab. Il faut que le tab est le focus pour que ca marche. Pourtant le "print" apparait ??? |
