class ToeButton extends Canvas {

}

}
(第一处) public boolean mouseDown(Event evt,int x,int y){
if(state==ToeDialog.BLANK){
state=parent.turn;
parent.turn=(parent.turn==ToeDialog.XX?ToeDialog.OO:ToeDialog.XX);

}
else

}
}
class ToeDialog extends Dialog {

static final int OO = 2;
int turn = XX;
public ToeDialog(Frame parent, int w, int h) {
super(parent, "The game itself", false);
setLayout(new GridLayout(w, h));
for(int i = 0; i < w * h; i++)
add(new ToeButton(this));
//resize(w * 50, h * 50);
setSize(w*50,h*50);

}

(第二处) public boolean handleEvent(Event evt) {
if(evt.id == Event.WINDOW_DESTROY)
dispose();
else
return super.handleEvent(evt);
return true;
}
}

public class ToeTest extends Frame{
TextField rows = new TextField("3");
TextField cols = new TextField("3");
/** Creates a new instance of ToeTest */
public ToeTest() {
setTitle("Toe Test");
Panel p = new Panel();
p.setLayout(new GridLayout(2,2));
p.add(new Label("Rows", Label.CENTER));
p.add(rows);
p.add(new Label("Columns", Label.CENTER));
p.add(cols);
add("North", p);
Button b=new Button("go");
b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
Dialog d=new ToeDialog(ToeTest.this,Integer.parseInt(rows.getText()),Integer.parseInt(cols.getText()));
d.setVisible(true);
}
});
add("South", b);
/*b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
Dialog d = new ToeDialog(this,Integer.parseInt(rows.getText()),Integer.parseInt(cols.getText()));
d.setVisible(true);
}
});*/
add("South",b);
}
/*public boolean handleEvent(Event evt) {
if(evt.id == Event.WINDOW_DESTROY)
System.exit(0);
else
return super.handleEvent(evt);
return true;
}*/

/*public boolean action(Event evt, Object arg) {
if(arg.equals("go")) {
Dialog d = new ToeDialog(this,Integer.parseInt(rows.getText()),Integer.parseInt(cols.getText()));
//d.show();
d.setVisible(true);
}
else
return super.action(evt, arg);
return true;
}*/

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
Frame f = new ToeTest();
f.setSize(200,100);
f.setVisible(true);

f.addWindowListener(
new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}
});

}
}
我在编译的时候,程序在这两处报了警告,请问我如何把这两处的代码换成新的消息机制.
