Question

类型 Container 中的方法 setLayout（LayoutManager）对于参数（FlowLayout）不适用

import java.awt.*;
import java.awt.event.*;
public class S123 extends Frame {
private WindowApply windowListener=new WindowApply();
public S123(){
super("S123");
setLayout(new FlowLayout());
add(new Button("buttob1"));
add(new Button("buttob2"));
add(new Button("buttob3"));
add(new Button("buttob4"));
add(new Button("buttob5"));
addWindowListener(windowListener);
pack();
setVisible(true);
}
public class WindowApply extends WindowAdapter{
public void windowClosing(WindowEvent we){
System.exit(0);
}
}
public static void main (String args[]){
S123 start=new S123();
}
}
怎么改？我是新手，求解！！！！

怎么不适用了，就是这种效果嘛

你是想让按钮都在窗口正中间？？？，那得对flowlayout进行设置setAlignment(int align)
或者构造的时候加参数new FlowLayout(int align)
