JFACE AppllicationWindow问题

我写了一段代码，目的是在一个窗口的移行排列6个按钮，但奇怪的是运行后在第一个按钮前多了一个横线，请帮忙看看问题在哪里，谢谢。
代码如下：
import org.eclipse.jface.window.ApplicationWindow;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Display;
public class SWTDefaultButtonWX extends ApplicationWindow{
public SWTDefaultButtonWX() {
  super(null);
  // TODO Auto-generated constructor stub
}
   
    protected Control createContents(Composite parent) {
     FillLayout myLayout = new FillLayout();
     parent.setLayout(myLayout);
     
     final String[] ratings={"Killer!","Good stuff","So-so","Needs work"};
     final Button[] radios = new Button[4];
     
     for (int i=0;i<4;i++) {
      radios[i] = new Button(parent,SWT.RADIO);
      radios[i].setText(ratings[i]);
     }
     
     final Button canelButton = new Button(parent,SWT.PUSH);
     canelButton.setText("Canel");
     
     final Button rateButton = new Button(parent,SWT.PUSH);
     rateButton.setText("Rate!");
     
  return parent;
}
   
    public static void main(String[] args) {
     SWTDefaultButtonWX db = new SWTDefaultButtonWX();
     db.setBlockOnOpen(true);
     db.open();
     Display.getCurrent().dispose();
    }
}

radios = new Button(parent,SWT.RADIO);
      radios.setText(ratings);

这2句有问题吧radios 是个button组，编译就通不过

对不起,代码粘错了,应当是下段:
import org.eclipse.jface.window.ApplicationWindow;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Display;

public class SWTDefaultButtonWX extends ApplicationWindow{

    public SWTDefaultButtonWX() {
        super(null);
        // TODO Auto-generated constructor stub
    }
   
    protected Control createContents(Composite parent) {
        FillLayout myLayout = new FillLayout();
        parent.setLayout(myLayout);
        
        final String[] ratings={"Killer!","Good stuff","So-so","Needs work"};
        final Button[] radios = new Button[4];
        
        for (int i=0;i<4;i++) {
            radios[i] = new Button(parent,SWT.RADIO);
            radios[i].setText(ratings[i]);
        }
        
        final Button canelButton = new Button(parent,SWT.PUSH);
        canelButton.setText("Canel");
        
        final Button rateButton = new Button(parent,SWT.PUSH);
        rateButton.setText("Rate!");
        
        return parent;
    }
   
    public static void main(String[] args) {
        SWTDefaultButtonWX db = new SWTDefaultButtonWX();
        db.setBlockOnOpen(true);
        db.open();
        Display.getCurrent().dispose();
    }
}
