如何在SWT MessageDialog或MessageBox中将焦点设置在文本上而不是按钮上？

import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.MessageBox;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

public class FocusExample {
    public static void main(String[] args) {
        Display display = new Display();
        Shell shell = new Shell(display);

        MessageBox messageBox = new MessageBox(shell, SWT.ICON_INFORMATION | SWT.OK);
        messageBox.setText("Message");
        messageBox.setMessage("Enter your name:");

        Text text = new Text(messageBox, SWT.BORDER);
        text.setBounds(10, 10, 200, 25);
        text.setFocus(); // 设置焦点在文本框上

        messageBox.open();

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