The previous example was a little artificial. Normally you create
your own subclass of Dialog and instantiate that
subclass from the main program. For example one of the simpler
common dialogs is a notification dialog that gives the user a
message to which they can say OK to signify that they've read it.
The following program is such a Dialog subclass.
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class YesNoDialog extends Dialog implements ActionListener {
private Button yes = new Button("Yes");
private Button no = new Button("No");
public YesNoDialog(Frame parent, String message) {
super(parent, true);
this.add(BorderLayout.CENTER, new Label(message));
Panel p = new Panel();
p.setLayout(new FlowLayout());
yes.addActionListener(this);
p.add(yes);
no.addActionListener(this);
p.add(no);
this.add(BorderLayout.SOUTH, p);
this.setSize(300,100);
this.setLocation(100, 200);
this.pack();
}
public void actionPerformed(ActionEvent evt) {
this.hide();
this.dispose();
}
}
