Bonjour,

Bien qu'ayant étudié un tuto sur developpez.com relatif au GridBagLayout, je suis bloqué sur un problème de placement.

Je voudrais avoir :

--------------------------------------------------------
! JLabel ! JLabel ! JTextArea ! JLabel ! JTextArea ! JButton !
--------------------------------------------------------
! JList ! JList !
--------------------------------------------------------
! JList !
--------------------------------------------------------

Au lieu de cela, j'ai :

--------------------------------------------------------
! JLabel ! JLabel ! JTextArea ! JLabel ! JTextArea ! JButton !
--------------------------------------------------------
!
!
!
--------------------------------------------------------
! JList ! JList !
--------------------------------------------------------
! JList !
--------------------------------------------------------

Quelqu'un saurait comment résoudre le problème?


Le code me donnant ce résultat est le suivant :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Je vous remercie d'avance pour votre aide.

En fait j'ai trouvé moi même : j'avais le "weighty" d'un label à "1" au lieu de "0".
Bonne journée à vous!
