使用弹出窗口将项目添加到数组列表 [英] Using a popup window to add items to arraylist

问题描述

我正在尝试使用弹出式面板来输入信息以添加到我的数组列表中.我找到了这个代码

I am trying to use a popup sort of panel to enter information in order to add to my arraylist. I found this code

    import javax.swing.*;

public class JOptionPaneMultiInput {

    public static void main(String[] args) {
        JTextField xField = new JTextField(15);
        JTextField yField = new JTextField(15);
        JTextField zField = new JTextField(15);

        JPanel myPanel = new JPanel();
        myPanel.add(new JLabel("Item Name:"));
        myPanel.add(xField);

        myPanel.add(Box.createVerticalStrut(15)); // a spacer
        myPanel.add(new JLabel("Number in inventory:"));
        myPanel.add(yField);

        myPanel.add(Box.createVerticalStrut(15)); // a spacer
        myPanel.add(new JLabel("Unit Price:"));
        myPanel.add(zField);

        int result = JOptionPane.showConfirmDialog(null, myPanel,
                "Please Enter data into all boxes", JOptionPane.OK_CANCEL_OPTION);
        if (result == JOptionPane.OK_OPTION) {

        }

    }
}

它自己工作并显示我需要显示的内容，但是如何让它与我的 actionListner 一起工作?我希望它在用户单击添加按钮时弹出.

which works on it's own and displays what I need displayed, however how do I get it to work with my actionListner? I want it to pop up when the user clicks on the add button.

我也不确定如何将此信息输入到我之前构建的存储数组列表中，但如果需要，我可以将其作为一个单独的问题.

I also am not sure how to input this information into my stored arraylist that was previously built, but I can make that a separate question if needed.

推荐答案

尝试，

JButton but = new JButton("Popup");
but.addActionListener(new ActionListener() {
 @Override
 public void actionPerformed(ActionEvent e) {
 final JPanel myPanel = new PopupPanel();// Create a separate class extends JPanel
     int result = JOptionPane.showConfirmDialog(null, myPanel,
          "Please Enter data into both boxes", JOptionPane.OK_CANCEL_OPTION);
            if (result == JOptionPane.OK_OPTION) {

            }
        }
    });
