如何在SWT中限制文本字段的大小？

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.VerifyEvent;
import org.eclipse.swt.events.VerifyListener;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

public class TextLimitExample {
    public static void main(String[] args) {
        Display display = new Display();
        Shell shell = new Shell(display);
        shell.setLayout(new FillLayout());

        Text text = new Text(shell, SWT.BORDER);

        // 设置文本字段的最大长度为10
        int maxLength = 10;
        text.setTextLimit(maxLength);

        // 添加VerifyListener监听器
        text.addVerifyListener(new VerifyListener() {
            @Override
            public void verifyText(VerifyEvent event) {
                // 获取用户输入的文本
                String newText = text.getText() + event.text;

                // 判断文本长度是否超过限制
                if (newText.length() > maxLength) {
                    // 阻止文本的输入
                    event.doit = false;

                    // 给用户一个提示
                    System.out.println("文本长度不能超过" + maxLength + "个字符");
                }
            }
        });

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

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

        display.dispose();
    }
}
