Question

这是我的代码问题是我无法找到为什么要创建一个额外的表单

        public void actionPerformed(ActionEvent ae){
           submitBtn.setForeground(Color.red);               
           //getting value form the textFields
           String name = nameTxt.getText();
           String userName = userNameTxt.getText();
           char[] pass = password.getPassword();
           Object monthValue = month.getSelectedItem();
           String yearValue = yearTxt.getText();
           String dateValue = dateTxt.getText();
           Object genderValue = gender.getSelectedItem();
           String mobileValue = mobileTxt.getText();
           Object locationValue = country.getSelectedItem();

           showDetails page = new showDetails();
           page.setVisible(true);
           JPanel contentPane = new JPanel();
           contentPane.setLayout(null);
           contentPane.setBorder(BorderFactory.createTitledBorder("user Details"));
           JLabel nameVL = new JLabel("Name             :            " + name );
           nameVL.setBounds(80, 30, 200, 200);
           contentPane.add(nameVL); 
           page.getContentPane().add(contentPane);               
        }

以上代码位于signuppage.java类

并创建一个表单以将标签结果显示到showDetails类

public class showDetails extends JFrame {

    Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();

    public showDetails() {
        JFrame showFrame = new JFrame("user details");
        showFrame.setDefaultCloseOperation(javax.swing.JFrame.DISPOSE_ON_CLOSE);
        showFrame.setSize(300, 400);
        showFrame.setVisible(true);
        showFrame.setLocation((screen.width - 500)/2,((screen.height-350)/2));
    }
}

但是我的问题是结果是没有在showFram中显示这个表单被创建不知道如何....

Answer 1

ShowDeatils从JFrame延伸，而在其构造函数中，您正在创建另一个JFrame，因此，每次创建新实例{{}}时，您都会创建两个框架{1}}

基本上，或者您需要做的是......

showDetails

摆动Jform创造
