java swing 定时任务小工具(java窗体样式可改变)

最近以来，由于一直比较闲，所以有时间干一些事情，所以就有了这个采用java swing来完成的这个小工具。由于比较简单。所以将所有的逻辑处理都放在了一个类中，规范性上不是很好。另外这个小工具可以换肤，采用了java内置的5中样式，可以导出成可运行的jar文件使用。ok，废话不说，直接看代码：

package com.yjck.timetask;


public class TimeTask extends JFrame implements ActionListener{

	private static final long serialVersionUID = 1L;
	private String path = null;
	private Map<Integer,String> map = new HashMap<Integer,String>();
	private JPanel mainPanel = null;
	private JPanel btPanel = null;
	private JRadioButton closeRadio = null;
	private JRadioButton resetRadio = null;

	private ButtonGroup btGroup = null;	
	private JLabel titleLabel = null;
	private JLabel timeLabel = null;	
	private JLabel lookAndFell = null;
	private JTextField timeField =null;
	private JTextField planField = null;
	private JButton browerBt = null;
	private JButton ConfirmBt = null;
	private JButton CancelBt = null;
	private JComboBox laf = null;
	
	public TimeTask(){
		init();
	}
	/**
	 * 填充下拉列表
	 * @return Vector<String>
	 */
	private Vector<String> initComboBos() {
		//获得所有java自带的样式
		LookAndFeelInfo[] lafInfo =  UIManager.getInstalledLookAndFeels();
		Vector<String> lafs = new Vector<String>();
		for (int i = 0; i < lafInfo.length; i++) {
			//将样式存入map中，以便在更改样式时能找到。
			map.put(i,lafInfo[i].getClassName());
			String[] temp = lafInfo[i].getClassName().split("\\.");
			String str = temp[temp.length-1].replace("LookAndFeel", "");
			lafs.addElement(str);
		}

 所有的代码都有注释，应该可以看懂的。布局是自己定位的gridbaglayout。其他的应该没啥说的了，只要是将java swing编程的一些特点都记录下来了，以便以后查用！
