一个JFrame不会停止其他帧的代码

Question

当用户点击编辑按钮时，会向他们显示一个新框架，当新框架关闭时我想要执行刷新线但问题是，在关闭新框架之前执行刷新线...我正在使用NetBeans来制作UI。

//If user clicks on edit button new frame will be shown to him 
EditUserFrame editUserFrame = new EditUserFrame();
Iterator itr = userList.iterator();
while(itr.hasNext()){
    user = (Users)itr.next();
    if((user.getF_name().equals(f_name) && user.getL_name().equals(l_name))){
        break;
    }
}//End of While Loop
editUserFrame.setUserObj(user);
editUserFrame.getExistingValues();
editUserFrame.setVisible(true);
//I want this line to be executed when the editUserFrame is closed..
RefreshUserTable();

我想要像这样的新框架可以按照你们的建议在JOPtionPane中制作图片。

您想要使用某种模式对话框。对话框旨在“停止”程序在显示时执行。

查看How to Make Dialogs。

您还可以使用JOptionPane让您更轻松，因为它们可以相对轻松地配置不同的按钮/选项。查看JOptionPane Features以获取概述

public class TestOptionPane01 {

    public static void main(String[] args) {
        new TestOptionPane01();
    }

    public TestOptionPane01() {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                }

                FormPane formPane = new FormPane();
                int result = JOptionPane.showConfirmDialog(
                                null, 
                                formPane, 
                                "Edit User", 
                                JOptionPane.OK_CANCEL_OPTION, 
                                -1);

                        break;

你可以使用

'editUserFrame.addWindowListener(new WindowAdapter()
{
    public void windowClosed(WindowEvent e){
    //call your method from here
        RefreshUserTable();
    }
};'

希望这会有所帮助
