GUI-based Applications
In this section you will learn about how to create a window for your
application. You need to define a subclass of Frame to create a window for your
application. The Frame consists of a Window with a title, menubar, and border.
Moreover, you need to construct an instance of that class through the main
method as shown below.
One point to remember here is that
Applications respond to events in the same way as applets do. In the
example given below, you will see that the Application responds to the native window toolkit
i.e. quit or close.
import java.awt.*;
import java.awt.event.*;
public class ApplicationWindow extends Frame{
public ApplicationWindow(){
super("ApplicationWindow");
setSize(200, 200);
addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent we){
setVisible(false); dispose();
System.exit(0);
}
});
}
public static void main(String[] args){
ApplicationWindow aw = new ApplicationWindow();
aw.setVisible(true);
}
}
