Java对话框 - 查看是否单击了确定？ [英] Java Dialog - Find out if OK is clicked?

问题描述

我有一个客户端GUI对话框，询问要连接的服务器的IP和端口。我还有其他所有内容，但是如何在用户点击对话框中的确定时进行操作呢？这是我到目前为止所拥有的：

I have a dialog for a client-GUI that asks for the IP and Port of the server one wants to connect to. I have everything else, but how would I make it so that when the user clicks "OK" on my dialog box, that it runs something? Here's what I have so far:

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JDialog;
import javax.swing.JOptionPane;
import javax.swing.JTextField;


public class ClientDialog {
    JTextField ip = new JTextField(20);
    JTextField port = new JTextField(20);
    GUI gui = new GUI();
    Client client = new Client();
    JOptionPane optionPane;

    public void CreateDialog(){

        Object msg[] = {"IP: ", ip, "\nPort: ", port};

        optionPane = new JOptionPane();
        optionPane.setMessage(msg);
        optionPane.setMessageType(JOptionPane.INFORMATION_MESSAGE);
        JDialog dialog = optionPane.createDialog(null, "Connect to a server");
        dialog.setVisible(true);

        if(dialog == JOptionPane.OK_OPTION){
            System.out.println(ip);

            String ipMsg = ip.getText();
            int portMsg = Integer.parseInt(port.getText());

            gui.CreateConsole(client, ipMsg, portMsg);
        }

    }

}   //End class

我知道代码不正确，但我想要的是当用户在对话框上点击OK时，我可以运行一些代码。谢谢！

I know that the code isn't correct, but what I want is that when the user hits "OK" on the dialog, I can run some code. Thanks!

推荐答案

我建议使用 showConfirmDialog 代替

int result = JOptionPane.showConfirmDialog(myParent, "Narrative", 
       "Title", JOptionPane.INFORMATION_MESSAGE);

在那里你可以测试来自 JDialog / JOptionPane的各种回报值

and there you can test for various returns value from JDialog/JOptionPane

if (result == JOptionPane.OK_OPTION, 
              JOptionPane.CANCEL_OPTION, 
              JOptionPane.CLOSED_OPTION, etc..
