java托盘开发界面记录

设置对话框为圆角：

//首先选择设置

JFrame.setDefaultLookAndFeelDecorated(true);

JDialog.setDefaultLookAndFeelDecorated(true);

//然后设置，其中login为登陆对话框

AWTUtilities.setWindowShape(login, new RoundRectangle2D.Double(0.0D,0.0D,login.getWidth(),login.getHeight(),15.0D,15.0D));

对话框居中：

//获取屏幕大小

Dimension screenSize=Toolkit.getDefaultToolkit().getScreenSize();

//设置位置，WIDTH、HEIGHT分别为对话框的宽高

int HEIGHT=200;

int WIDTH=300;

setLocation(screenSize.width/2-WIDTH/2, screenSize.height/2-HEIGHT/2);

初始化系统托盘：

//系统托盘

 private SystemTray tray = null;

//托盘图标

 private TrayIcon trayIcon = null;

 //托盘图标图像

 private Image icon = null;

 //图标图像路径

 private final String ICON_PATH = "icons/app.png";

//系统名称

 private String SYSTEM_NAME = "提醒助手";

tray = SystemTray.getSystemTray();

ImageIcon imageIcon = new ImageIcon(this.getClass().getClassLoader().getResource(ICON_PATH));  //获得托盘显示图标

icon=imageIcon.getImage(); //获得Image对象

   

trayIcon=new TrayIcon(icon,SYSTEM_NAME,trayMenu);

trayIcon.setImageAutoSize(true); 

   

trayIcon.setToolTip(SYSTEM_NAME);

try{

    tray.add(trayIcon);

   }catch(AWTException e){

    System.out.println("托盘初始化出现故障：" + e.getMessage());

    e.printStackTrace();

   }

消息提醒框显示在右下角：

    private JFrame jf;

    //JPanel

    private JPanel jp;

    //超链接

    private LinkLabel lb; 

    //控制窗口弹出效果的参数

    private Integer screenWidth;  // 屏幕宽度

    private Integer screenHeight; // 屏幕高度

    private Integer windowWidth = 300; // 设置提示窗口宽度

    private Integer windowHeight = 150; // 设置提示窗口高度

    private Integer bottmToolKitHeight; // 底部任务栏高度，如果没有任务栏则为零

    private Integer stayTime = 5000; // 提示框停留时间

    private Integer x; // 窗口起始X坐标

    private Integer y; // 窗口起始Y坐标

  //控制窗口弹出效果

        bottmToolKitHeight = Toolkit.getDefaultToolkit().getScreenInsets(jf.getGraphicsConfiguration()).bottom;

        Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();

        screenWidth = dimension.width;

        screenHeight = dimension.height;

        x = screenWidth - windowWidth;

        y = screenHeight;

        jf.setLocation(x, y - bottmToolKitHeight - windowHeight);

        jf.setSize(windowWidth, windowHeight);

        jf.setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);

消息列表，用JTable实现：

private JTable jTable = null;

//初始化jtable的数据

  Object rowData[][] = new Object[list.size()][4];

  for(int i=0;i<list.size();i++){

   Message msg = list.get(i);

   rowData[i][0]= msg.getMsg();

   rowData[i][1]= msg.getTime();

   rowData[i][2]= msg.getMsgUrl();

   rowData[i][3]= msg.getFrom();

  }

  Object[] columnNames = new Object[]{"消息内容","接收时间","链接","发送者"};

//设置jtable不可编辑

  TableModel tableModel = new DefaultTableModel(rowData,columnNames){

   public boolean isCellEditable(int rowIndex,int columnIndex){

    return false;

   }

   

  };

//设置表格单元格当鼠标停留时悬浮显示全部内容

jTable = new JTable(tableModel){

    @Override

    public String getToolTipText(MouseEvent event) {

     int row = jTable.rowAtPoint(event.getPoint());

     int col = jTable.columnAtPoint(event.getPoint());

     String tip=null;

     if(row>-1 && col>-1){

      Object value = jTable.getValueAt(row, col);

      if(null!=value && !"".equals(value)){

       tip = value.toString();

      }

     }

     return tip;

    }

   };

  int width = 125;

  //设置列宽

  TableColumnModel tcm = jTable.getColumnModel();

  TableColumn tc1 = tcm.getColumn(1);

  tc1.setPreferredWidth(width);

  tc1.setMaxWidth(width);

  tc1.setMinWidth(width);

// tc1.setResizable(false);

 

  TableColumn tc = tcm.getColumn(2);

  tc.setMaxWidth(width);

  tc.setMinWidth(width);

  tc.setPreferredWidth(width);

// tc.setResizable(false);

 

  int width1= 100;

  TableColumn tc3 = tcm.getColumn(3);

  tc3.setMaxWidth(width1);

  tc3.setMinWidth(width1);

  tc3.setPreferredWidth(width1);

// tc3.setResizable(false);
