Jtable Custom Cell Renderer et Editor problème de focus
Bonjour
J'ai créé un renderer et une editor qui contiennent un JPanel avec une checkbox et une combobox.
Mon problème est que il faut que je clique une fois sur la cellule ou la ligne pour la sélectionner et une fois de plus pour pouvoir sélectionner ou non la checkbox/combobox.
Je n'arrive pas a trouver comment faire pour que l'utilisateur puisse directement sélectionner la checkbox/combobox (Quand je passe la souris sur les composants le rollover n'est pas activé).
