JFrame et plusieurs JPanel
Bonjour à tous,
J'aimerais savoir quelles solutions adoptées pour que dans le cadre où une JFrame possède plusieurs JPanels chaque JPannel puisse se connaitre.
Le but étant que lorsque je valide une option sur un JPanel je sois rediriger vers un autre JPanel.
Dans mon exemple, lorsque je clique sur le bouton "update" j'aimerais être redirigé du View_ vers View__
Si vous avez des solutions je suis preneur.
Merci
