J'essaie de modifier facilement une table en utilisant un composant personnalisé pour afficher des informations. Chaque cellule contient 3 textes de données.Traversée de focus dans les composants d'un éditeur de cellules
Ce que je veux est:
- si une cellule se concentrer, commencer à modifier la valeur 1er.
- lors de l'édition de la 1ère valeur presse utilisateur [TAB], puis allez éditer la 2ème valeur (ne pas aller à la cellule suivante)
- si j'appuyez sur [TAB] dans la 3ème valeur, alors, allez éditer la prochaine cellule (saisie de la valeur 1sr)
Je recherche Wass dans les forums un i didnt trouver ce cas, ce problème ... lire encore apprendre swing
Merci d'avance pour vos réponses, c'est mon code:
public class PruebaTabla extends JFrame {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable(){
