我想知道如何在第二個JFrame(2)中單擊按鈕時打開此JFrame表單(1)。問題是我無法獲取Form 2中的.setVisible方法。請幫忙。謝謝&關心! :)通過單擊按鈕打開新的JFrame
表1(當點擊表格按鈕2
public class FlightForm {
public FlightForm() {
initialize();
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
FlightForm window = new FlightForm();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
}
表2
public class MainMenu{
private JFrame frame;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
MainMenu window = new MainMenu();
window.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public MainMenu() {
frame = new JFrame("Main Menu");
setBounds(100, 100, 830, 574);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
JButton btnNewButton = new JButton("Flight Form");
);
btnNewButton.setFont(new Font("Candara", Font.BOLD, 15));
btnNewButton.setBounds(169, 328, 193, 77);
frame.getContentPane().add(btnNewButton);
JButton btnNewButton_1 = new JButton("Passenger Form");
btnNewButton_1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
PassengerForm window = new PassengerForm();
window.setVisible(true); // This is not working
