Petit problème de variables entre tabbedPane et tabbedPanes :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

for (JTabbedPane tabbedPane : lstTabbedPane) {
	tabbedPanes.add(tabbedPane.getName(), tabbedPane);
 
	IhmConverter.getHDMT().add(tabbedPanes);
}

Maintenant j'ai l'affichage , mais l'affichage un petit problème, il me crée un onglet et en dessous les onglets ou peut-être que ses la suite mais qu'il manque de place, de toute façon il est sensé mettre les noms de chaque feuilles ce qu'il ne fait pas Pourquoi ?
La console avec un System.out.println(tabbedPanes) :

**joel.drigo** · 25/03/2016, 11h08

Je ne comprends pas pourquoi tu as transformé les JPanel en JTabbedPane, alors que ça fonctionnait très bien : tu te retrouves avec des JTabbedPane à un onglet qui sont des onglets d'un autre JTabbedPane. Quel intérêt ?
Le nom du JTabbedPane (obtenu par getName()) n'a jamais constitué le nom de l'onglet : lequel ça serait s'il y en avait plusieurs (parce que en général, quand on fait des onglets, c'est qu'on en a plusieurs, sinon on fait juste un JPanel) ? On peut appeler setName(unNom) pour récupérer un nom par getName().

Quant à l'exception que tu as, ça vient probablement du fait que tu remplaces le LayoutManager des JTabbedPane par le tiens (un BorderLayout). A vouloir faire des trucs trop tordus et compliqués... Bon, Sun/Oracle aurait pu protéger la méthode setLayout de JTabbedPane pour empêcher le plantage pendant le rendu, mais fallait penser à l'époque que quelqu'un utilise un JTabbedPane pour faire autre chose que du panneaux à onglet.

**nadong94** · 25/03/2016, 11h32

Donc je change le JTabbedPane de mes sous ongelts alors et je vais voir.

**nadong94** · 25/03/2016, 11h56

Tu as raison c'est presque bon, j'ai les onglets et le nom qui correspond bien mais, je n'ai plus les jtable.

Peut-être parce que tu leur donne une largeur de 0 :

This may indicate that the file is used to inflate memory usage and thus could pose a security risk. You can adjust this limit via ZipSecureFile.setMinInflateRatio() if you need to work with files which exceed this limit.

J'ai cru comprendre que c'est à cause de la taille du fichier mais je suis pas sûr, et si c'est le cas comment y remédier ?

**joel.drigo** · 25/03/2016, 12h24

Il vient d'où ce fichier ? Parce qu'une ZipBomb c'est n'est pas normal (certains fichiers malveillants utilisent cette technique): c'est une configuration de compression dont on estime qu'elle va consommer tellement de ressources pour décompresser, que ça risque de provoquer un gel de la machine, ou un dépassement de mémoire.

On peut ajuster ce paramètre au besoin, comme indiqué dans le message d'erreur :

C'est un fichier XLSX qui fait 3,23 Mo sur le disque, et il n'est pas protégé... C'est étrange que ça fasse ça !
Tant pis, je vais mettre le "ZipSecureFile.setMinInflateRatio()" alors.

**nadong94** · 25/03/2016, 14h07

J'ai fait un :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

double ratio = 0.009900990099009901;
ZipSecureFile.setMinInflateRatio(ratio);

dans le main, est toujours le même message, faut-il que je le mette ailleurs ?

Dis moi je souhaite faire un table.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
Je l'ai mis là où je crée mon JTable.
Mais mon curseur ne fait rien :
