timeraction.java

这个文件里面包含了java设计模式的一些例子讲解

package com.javapatterns.observertimer.cursor;

import javax.swing.AbstractAction;
import java.applet.Applet;
import java.awt.event.ActionEvent;
import java.awt.Cursor;

public class TimerAction extends AbstractAction
{
	private int ind = 0;
	private Applet applet;

    public TimerAction(Applet applet)
    {
        this.applet = applet;
    }

	public void actionPerformed(ActionEvent e)
	{
		if (ind == 0)
		{
			drawCursor(Cursor.NE_RESIZE_CURSOR);
		}
		else if (ind == 1)
		{
			drawCursor(Cursor.N_RESIZE_CURSOR);
		}
		else if (ind == 2)
		{

		{

	}

	public void drawCursor(int cursorType)
