oui ok c vrai la scroll n a pas l air de suivre mais neanmoins si tu la selectionne avec la souris ca va direct la ou tu veux dans le film.
Je regarde pour le scroll.

Commentaire de thierrytitix le 14/07/2004 18:19:29

Bon ben voila je te livre le fichier corrigé avec un thread en plus pour bouger la barre ca a l air de marcher mais c de l approximatif , je debute en multithread.
C est aussi de l approximatif pour la barre de scroll qui ne devrait pas etre la representation exacte de la longueur du film mais plutot d'un multiple de cette longueur afin de faire un entier sinon la derniere seconde risque de ne pas etre représentée sur la barre enfin bon tu me diras c pas si grave.
Parfois il arrive des erreurs mais non bloquantes.

Comment ( "java nomdufichier")? comme appelle d'un module externe? 'avec (exec (java nomdufichier))? mais pour ça, il faudra que la commande java soit reconnu.

en fait moi je suis sous linux et je travail avec  le serveur apache. Mon souci est de permettre à partir d'un clik sur un nom de video(sous forme de lien) le document video joue dans le player.

Avez vous une solution pour ça?
