Drag and drop d'un JPanel à un autre
Bonjour,
Je suis en train de travailler sur un projet qui va permettre de dessiner des réseaux électriques et je bloque sur le drag and drop.
J'ai une frame qui contient 2 JPanel, un JPanel de composant et un autre pour les dessins. L'objectif ici est de porter un JLabel du JPanel de composant pour le déposer dans le JPanel de dessin et gérer les enlèvements liés au JLable dépose.
Je débute en Java...
Quelqu'un aurait-il un idée sur comment procéder ?
Voici mon code:
