[Swing] probleme de GridBagLayout
Bonjour,
Je cherche a construire une fenetre de ce type:
...._______________________________________________
...|.............................................................................................................|
...|................................................"Nord".................................................|
...|_______________________________________________|
...|.....................|.......................................................................................|
...|.....................|.......................................................................................|
...|.....................|.......................................................................................|
...|....."West"....|........................."Center"...............................................|
...|.....................|.......................................................................................|
...|.....................|.......................................................................................|
...|.....................|.......................................................................................|
...|.....................|.......................................................................................|
...|.....................|_____________________________________ |
...|_________|____________"South"____________________|
Qui ressemble a un borderLayout mais pas exactement. Je l'ai decoupe de la maniere suivante en grille (13*5) pour conserver les rapports de taille:
...._______________________________________________
...|_________|_________|_________|_________|_________|
...|_________|_________|_________|_________|_________|
...|_________|_________|_________|_________|_________|
...|_________|_________|_________|_________|_________|

...|_________|_________|_________|_________|_________|
...|_________|_________|_________|_________|_________|
...|_________|_________|_________|_________|_________|
...|_________|_________|_________|_________|_________|
J'ai donc ecrit le code suivant:

[ce code est directement executable dans un fichier Test.java, si vous voulez voir ce que ca donne..]
Mais je n'obtiens pas le rapport de taille que je desirais. En effet, le centre a la meme hauteur que le sud, et il semble que cette taille depend du contenu des panels. Comment faire pour forcer cette disposition?
