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.您知道您可以将任何 Object 放入大多数 JOptionPane.showXXX 方法 的 Object 参数中，通常是 Object> 恰好是一个 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.

在您的情况下，也许您可​​以使用包含多个 JTextFields 的 JPanel:

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());
      }
   }
}
