將 Swing GUI 添加到現有的工作 Java 程序

Question

我已經在互聯網上搜索了有關將 Swing GUI 添加到現有 Java 程序的信息，但我仍然對如何實現它感到有些困惑。

我為表單布局創建了一個單獨的類，並且可以從主類調用/打開表單窗口。 我從互聯網上獲得了 GUI 的基本代碼......

圖形界面類：

package gui;

import javax.swing.*; 
import java.awt.*; 
import java.awt.event.*; 

public class MainWindow extends JFrame implements ActionListener {

    private Container c; 
    private JLabel title; 
    private JLabel masterFilePath; 
    private JTextField masterFilePathInput; 
    private JLabel dataFilePath; 
    private JTextField dataFilePathInput; 
    private JButton reset;

    String def = ""; 

    public void mainWindow() {

        setTitle("Count Survey Comparison"); 
        setBounds(300, 90, 900, 600); 
        setDefaultCloseOperation(EXIT_ON_CLOSE); 
        setResizable(false); 

        c = getContentPane(); 
        c.setLayout(null); 

        title = new JLabel("Count Survey Comparison"); 
        title.setFont(new Font("Arial", Font.PLAIN, 30)); 
        title.setSize(500, 30); 
        title.setLocation(300, 30); 
        c.add(title); 

        masterFilePath = new JLabel("Master Data File Location"); 
        masterFilePath.setFont(new Font("Arial", Font.PLAIN, 20)); 
        masterFilePath.setSize(500, 20); 
        masterFilePath.setLocation(80, 100); 
        c.add(masterFilePath); 

        masterFilePathInput = new JTextField(); 
        masterFilePathInput.setFont(new Font("Arial", Font.PLAIN, 15)); 
        masterFilePathInput.setSize(200, 20); 
        masterFilePathInput.setLocation(400, 100); 
        c.add(masterFilePathInput); 

        dataFilePath = new JLabel("Count Survey Data File Location"); 
        dataFilePath.setFont(new Font("Arial", Font.PLAIN, 20)); 
        dataFilePath.setSize(500, 20); 
        dataFilePath.setLocation(80, 150); 
        c.add(dataFilePath); 

        dataFilePathInput = new JTextField(); 
        dataFilePathInput.setFont(new Font("Arial", Font.PLAIN, 15)); 
        dataFilePathInput.setSize(200, 20); 
        dataFilePathInput.setLocation(400, 150); 
        c.add(dataFilePathInput); 

        reset = new JButton("Reset"); 
        reset.setFont(new Font("Arial", Font.PLAIN, 15)); 
        reset.setSize(100, 20); 
        reset.setLocation(270, 450); 
        reset.addActionListener(this); 
        c.add(reset); 

        setVisible(true); 
    } 

    public void actionPerformed(ActionEvent e) { 


    }
}

進入 actionPerformed 的動作應該是什么？

我可以從我的主方法調用該類，並打開表單，但我不知道如何從表單本身獲取數據，並將它們輸入到我現有的代碼中（即 readExcel(...) 方法）

主要方法：

MainWindow window = new MainWindow();
            window.mainWindow();

            ReadExcel readExcel = new ReadExcel();
            CompareAndCleanData cleanData = new CompareAndCleanData();
            WriteExcel writeExcel = new WriteExcel();

            /* Change file paths here */

            /* Based on BSTVN Data */
            System.out.println("Read Input Excel Data: In Progress...");
            List<VehicleData> vehicleDataList = readExcel.readExcel(
                    "C:\\Users\\ray.tong\\Desktop\\Count Survey Digitalisation Things\\BSTVN\\Count survey data (PSR19, TBR18).xlsx");
            System.out.println("Read Input Excel Data: Complete");

            /* Read MasterData */
            System.out.println("Read Brand Master Data: In Progress...");
            List<BrandMasterData> brandMasterDataList = readExcel
                    .readBrandMaster("C:\\Users\\ray.tong\\Desktop\\Count Survey Digitalisation Things\\TireMasterData.xlsx");
            System.out.println("Read Brand Master Data: Complete");

            System.out.println("Read Size Master Data: In Progress...");
            List<SizeMasterData> sizeMasterDataList = readExcel
                    .readSizeMaster("C:\\Users\\ray.tong\\Desktop\\Count Survey Digitalisation Things\\TireMasterData.xlsx");
            System.out.println("Read Size Master Data: Complete");

            System.out.println("Read Pattern Master Data: In Progress...");
            List<PatternMasterData> patternMasterDataList = readExcel
                    .readPatternMaster("C:\\Users\\ray.tong\\Desktop\\Count Survey Digitalisation Things\\TireMasterData.xlsx");
            System.out.println("Read Pattern Master Data: Complete");

            System.out.println("Read Vehicle Make/Model Master Data: In Progress...");
            List<VehicleMasterData> vehicleMasterDataList = readExcel
                    .readVehicleMaster("C:\\Users\\ray.tong\\Desktop\\Count Survey Digitalisation Things\\TireMasterData.xlsx");
            System.out.println("Read Vehicle Master Data: Complete");

任何幫助表示贊賞，

在此先感謝各位。

我建議通過實現MVC Pattern將 gui 與其控制分開。
有一個Model類，其中包含視圖 (gui) 需要的所有信息。
有一個使用模型來顯示 gui 的View類。
有一個Controller模型和視圖的Controller類。

以下mre演示了具有非常簡單功能的 MVC 模式的使用：它允許用戶選擇一個文件。 選擇文件后，將顯示文件名。 它可以擴展以包含您需要的功能。
為了方便和簡單，可以將以下代碼復制粘貼到一個名為MVCDemo.java文件中並運行：

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JTextField;

public class MVCDemo {

    public static void main(String[] args) {
        Model model = new Model();
        View view = new View();
        new Controller(view, model);
    }
}

/*Model contains the information for the view and information from the view
 * as well as the logic.
 * The model is independent of the user interface.
 */
class Model {

    private String fileName;

    String getFileName() {
        return fileName;
    }

    void setFileName(String fileName) {
        this.fileName = fileName;
    }
}

/*View only contains the user interface part*/
class View {

    private Model model;
    private JFrame frame;
    private JButton selectFileButton;
    private JTextField textField;

    void createAndShowGui(Model model){

        this.model = model;

        frame = new JFrame("MVC Model Demo");
        textField = new JTextField(25);
        //do not use null layout
        frame.add(textField, BorderLayout.NORTH); //JFrame uses BorderLayout by default
        selectFileButton = new JButton("Select File");
        frame.add(selectFileButton, BorderLayout.SOUTH);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocationRelativeTo(null);
        frame.pack();
        frame.setVisible(true);
    }

    //may return null
    File getFile(){
        JFileChooser fileChooser = new JFileChooser();
        fileChooser.setFileSelectionMode(JFileChooser.FILES_ONLY);  
        // pop up  file chooser dialog
        fileChooser.showOpenDialog(frame);
        return fileChooser.getSelectedFile();
    }

    void update() {
        textField.setText(model.getFileName());
    }

    JButton getSelectFileButton() {
        return selectFileButton;
    }
}

/* The controller controls the view and model.
 * Based on the user action, the Controller calls methods in the View and Model
 * to accomplish the requested action.
 */
class Controller implements ActionListener{

    private final Model model;
    private final View view;

    Controller(View view,Model model) {
        this.model=model;
        this.view=view;
        view.createAndShowGui(model);
        view.getSelectFileButton().addActionListener(this);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        File file = view.getFile();
        model.setFileName(file == null  ? "No file selected" : file.getName());
        view.update(); //alternatively use have View listen to Model changes 
    }
}
