[Debian / Jigloo / Eclipse] Je débute avec Swing - problème basique
bonjour,
une petite question : j'ai pour but de créer une appli qui a le comportement suivant : une classe principale, avec une méthode main, instancie et affiche une JFrame.Cette JFrame possède un menu dont un item instancie et affiche une JDialog, qui contient une JTable.
problème : avec les listings donnés ci-dessous, j'ai les problèmes suivants : la JFrame s'affiche bien, je clique sur l'item de menu, et là il se passe disons 5 secondes avant que la JDialog s'affiche.c'est gênant. autre problème : la JTable ne s'affiche pas, et j'arrive en survolant la JDialog à faire apparaître les titres de colonnes. là aussi c'est gênant.
savez-vous comment je peux arranger les choses?
