用Java写一个SWT类-应用程序窗口班级姓名学号的代码

下面是一个使用 SWT 库编写的应用程序窗口代码，其中包括班级、姓名和学号的文本框：

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

public class ApplicationWindow {
    private Text textClass;
    private Text textName;
    private Text textNumber;

    public static void main(String[] args) {
        Display display = new Display();
        Shell shell = new Shell(display);
        shell.setText("Application Window");
        shell.setLayout(new GridLayout(2, false));

        // 添加班级标签和文本框
        Label labelClass = new Label(shell, SWT.NONE);
        labelClass.setText("Class:");
        textClass = new Text(shell, SWT.BORDER);
        textClass.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));

        // 添加姓名标签和文本框
        Label labelName = new Label(shell, SWT.NONE);
        labelName.setText("Name:");
        textName = new Text(shell, SWT.BORDER);
        textName.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));

        // 添加学号标签和文本框
        Label labelNumber = new Label(shell, SWT.NONE);
        labelNumber.setText("Number:");
        textNumber = new Text(shell, SWT.BORDER);
        textNumber.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false));

        // 添加确认按钮
        Button button = new Button(shell, SWT.PUSH);
        button.setText("OK");
        button.addSelectionListener(new SelectionAdapter() {
            public void widgetSelected(SelectionEvent event) {
                String classStr = textClass.getText();
                String nameStr = textName.getText();
                String numberStr = textNumber.getText();
                System.out.println("Class: " + classStr + ", Name: " + nameStr + ", Number: " + numberStr);
            }
        });

        shell.pack();
        shell.open();

        while (!shell.isDisposed()) {
            if (!display.readAndDispatch())
                display.sleep();
        }
        display.dispose();
    }
}

上述代码创建了一个基本的 SWT 应用程序窗口，其中包括班级、姓名和学号的文本框以及一个确认按钮。在单击确认按钮后，将在控制台上显示输入文本框中的值。
