改成这样:
import java.applet.Applet;
import java.awt.*;
public class mapplet extends Applet {
/**
* @param args
*/
Button button1=new Button("button1");
Button button2=new Button("button2");
Button button3=new Button("button3");
Button button4=new Button("button4");
Button button5=new Button("button5");
Button button6=new Button("button6");
Button button7=new Button("button7");
Button button8=new Button("button8");
Button button9=new Button("button9");
public void init( ){
GridBagLayout layout=new GridBagLayout( );
GridBagConstraints gbc=new GridBagConstraints( );
gbc.fill=GridBagConstraints.BOTH;
setLayout(layout);
gbc.weightx=1;
gbc.weighty=1;
layout.setConstraints(button1,gbc);
add(button1);
}
}
