Je suis nouveau à Java swing. J'ai un problème en invoquant mon Jframe de la classe principale. Ce peut être un doublon mais je ne peux pas savoir pourquoi mon code n'est pas travaillé. Donc, je poste ici.IllegalArgumentException ajoutant une fenêtre à un conteneur.
MainClass
public static void main(String[] args) {
// TODO code application logic here
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
SendMail sendMail = new SendMail();
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(sendMail,BorderLayout.CENTER);
frame.pack();
frame.setVisible(true);
}
});
}
