bonjour,
Je suis en train de creer mon petit logiciel est je bute sur quelque chose qui me paraissait simple avant de commencer.

Je vous donne ma class elle est fonctionnelle ,mais voila je voulais juste rajouter un scrollbar a ma jtable mais rien a faire.
Je ne comprend vraiment pas ou est le probleme.
j ai beaut utiliser ScollPanel ou ScrollBar, rien , la compilation est bonne mais rien ne s affiche.
Si quelqu un peu m aider, ca serait sympa.

merci

Il te faut mettre ta JTable dans une JScrollPane.

Code :

JTable maTable = new JTable (monTableModel);
JScrollPane scrollPane = new JScrollPane(maTable);
maFrame.add(scrollPane);

merci pour la reponse,
c est quelque chose que j ai essayé de faire sans succes,

J essaie de passer par un getcontentpane mais la aussi rien a faire.

Je me demande si c est pas l architectute de mon code qui ne permet pas d ajouter un scroll, j espere que non.

je seche completement!

[bergoliv]

mon code contient deux panel , peut etre y il a t il un probleme de gestion du scroll avec plusieurs panel dans une frame?

[bergoliv]

Je pensais avoir trouvé mon soucie, mais non,

Une chose n allait pas , J avais cree 2 Jpanel et un Scrolpanel donc = 3 panel!

j ai suprimé un Jpanel : JPanel panelHaut = new JPanel();


j affecte mon tableau a ma table
JTable table = new JTable(new MyTableModel());

puis j ai mis ma table dans le Jscrollpanel :
JScrollPane panelHaut = new JScrollPane(table);

ensuite j ajoute mon panelHaut a ma frame
getContentPane().add(panelHaut, BorderLayout.NORTH);


Je pensais avoir resolut le probleme mais non; tout est bon mais toujours pas de scroll!!!!!

[bergoliv]

AAAAAAAHHH enfin!!


Il ne faut pas preciser "BorderLayout.NORTH" dans

getContentPane().add(panelHaut, BorderLayout.NORTH);


va comprendre, l essentiel est que ca marche.
