JOptionPane.showInputDialog中的多个输入 [英] Multiple input in JOptionPane.showInputDialog

问题描述

有没有办法在 JOptionPane.showInputDialog 中创建多个输入而不只是一个输入？

Is there a way to create multiple input in JOptionPane.showInputDialog instead of just one input?

推荐答案

是的。您知道可以将任何 Object 放入大多数 JOptionPane.showXXX方法的 Object 参数中，通常对象恰好是 JPanel 。

Yes. You know that you can put any Object into the Object parameter of most JOptionPane.showXXX methods, and often that Object happens to be a JPanel.

在你的情况下，也许你可以使用 JPanel ，它有几个 JTextFields in它：

In your situation, perhaps you could use a JPanel that has several JTextFields in it:

import javax.swing.*;

public class JOptionPaneMultiInput {
   public static void main(String[] args) {
      JTextField xField = new JTextField(5);
      JTextField yField = new JTextField(5);

      JPanel myPanel = new JPanel();
      myPanel.add(new JLabel("x:"));
      myPanel.add(xField);
      myPanel.add(Box.createHorizontalStrut(15)); // a spacer
      myPanel.add(new JLabel("y:"));
      myPanel.add(yField);

      int result = JOptionPane.showConfirmDialog(null, myPanel, 
               "Please Enter X and Y Values", JOptionPane.OK_CANCEL_OPTION);
      if (result == JOptionPane.OK_OPTION) {
         System.out.println("x value: " + xField.getText());
         System.out.println("y value: " + yField.getText());
      }
   }
}
