import org.jfree.ui.ApplicationFrame 是界面方面的类
其实它就只是一个窗口类
即public Frame(String title) throws HeadlessException
下面贴出它的原代码
package org.jfree.ui;
import java.awt.event.WindowEvent;import java.awt.event.WindowListener;
import javax.swing.JFrame;
/** * A base class for creating the main frame for simple applications. The frame listens for * window closing events, and responds by shutting down the JVM. This is OK for small demo * applications...for more serious applications, you'll want to use something more robust. * * @author David Gilbert */public class ApplicationFrame extends JFrame implements WindowListener {
/** * Constructs a new application frame. * * @param title the frame title. */ public ApplicationFrame(final String title) { super(title); addWindowListener(this); }
/** * Listens for the main window closing, and shuts down the application. * * @param event information about the window event. */ public void windowClosing(final WindowEvent event) { if (event.getWindow() == this) { dispose(); System.exit(0); } }
/** * Required for WindowListener interface, but not used by this class. * * @param event information about the window event. */ public void windowClosed(final WindowEvent event) { // ignore }
