gestionnaire fonctionnant à moitié

**Pallas4** · 02/05/2006, 18h27

Bonjour

J'ai un problème avec le GridBagLayout... J'ai fait quelques recherches mais vu le nombre de réponse je n'ai pas pu toutes les regarder et celes que j'ai regardées ne m'aident pas

voilà j'essaye de faire marcher le code que je vais mettre en fin de message (pardon pour l'aspect rudimentaire mais c'est un code de test). Pour faire simple, ce code doit permettre à l'utilisateur de rentrer en mode console des données : (position X, position Y, dimensions) et grâce à la fonction paneCen, les utiliser dans un gestionnaire GridBagLayout... (lignes 75 à 81).
Quand je lance le programme, tout se met en place sauf que les Jpanel PaneCentre,PaneCentre2 et PaneCentre3 sont toujours de la même taille 10*10...
Si quelqu'un sait ce que j'ai fait comme erreur...

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Avec l'attribut fill de tes GridBagConstraints à NONE il est évident que rien ne change de taille, passe le à HORIZONTAL si tu veux que ton panel occupe la largeur, VERTICAL pour la hauteur et BOTH pour les deux

**Pallas4** · 02/05/2006, 19h07

Malhjeureusement j'ai essayé..

J'ai aussi remplacé gbc.fill = gbc.BOTH par gbc.fill = GridBagConstraints.BOTH mais rien n'y fait..

**sinok** · 02/05/2006, 19h15

Dans la partie du code que je vois elle est à NONE cette valeur.

Sinon quelle sont les valeurs entrées pour tes weightx et weighty?

J'ai posté cette version du code mais j'ai fait des tests et j'ai mis la dernière version que j'ai faite... Mais qui plante tout autant que les autres ^^'
Pour weightx et weighty ce sont les mêmes valeurs que gridheight et gridwith. (au passage j'avais également testé sans weightx et weighty)
