如何將東西添加到系統托盤並添加mouseOver（）功能？

enter image description here 如何將東西添加到系統托盤並添加mouseOver（）功能？

對不起，如果標題含糊不清，但這是我想實現的。
這是Battery Care軟件iconified /最小化。當您將鼠標懸停在圖標上時，您會看到圖片中顯示的窗口。
這怎麼可以在Java中實現？

也許您可以從[這個]（http://stackoverflow.com/questions/1882055/java-swing-change-background-color-on-mouse-over） – Jeff

首先看看[如何使用系統托盤]（http：///docs.oracle.com/javase/tutorial/uiswing/misc/systemtray.html） – MadProgrammer

這是關於系統托盤的具體內容嗎？或者您只想瞭解onMouseOver事件？對於系統托盤功能，您可以看到http：// docs。 oracle.com/javase/tutorial/uiswing/misc/systemtray.html –

這將使用JPopupMenu上顯示點擊信息，而不是最值得推薦的方法，因爲它很難佈置其他組件...但你可以很容易地使用一個JWindow，而不是...

public class SystemTrayTest { 

    public static void main(String[] args) { 
    if (SystemTray.isSupported()) { 

     EventQueue.invokeLater(new Runnable() { 
     @Override 
     public void run() { 
      try { 
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); 
      } catch (Exception ex) { 
      } 
      try { 
      final JPopupMenu popup = new JPopupMenu(); 
      popup.add(new JLabel("Charging (45%)", JLabel.CENTER)); 

      popup.add(new JLabel("Charging", new ImageIcon(ImageIO.read(SystemTrayTest.class.getResource("/battery_connection.png"))), JLabel.LEFT)); 
      popup.add(new JLabel("Power Saver", new ImageIcon(ImageIO.read(SystemTrayTest.class.getResource("/flash_yellow.png"))), JLabel.LEFT)); 

      popup.add(new JSeparator()); 

      JMenuItem exitMI = new JMenuItem("Exit"); 
      exitMI.addActionListener(new ActionListener() { 
       @Override 
       public void actionPerformed(ActionEvent e) { 
       System.exit(0); 
       } 
      }); 
      popup.add(exitMI); 

      TrayIcon trayIcon = new TrayIcon(ImageIO.read(SystemTrayTest.class.getResource("/battery_green.png")), "Feel the power"); 
      trayIcon.addMouseListener(new MouseAdapter() { 
       @Override 
       public void mouseClicked(MouseEvent e) { 
       popup.setLocation(e.getX(), e.getY()); 
       popup.setInvoker(popup); 
       popup.setVisible(true); 
       } 
      }); 
      SystemTray.getSystemTray().add(trayIcon); 
      } catch (Exception ex) { 
      ex.printStackTrace(); 
      System.exit(0); 
      } 

     } 
     }); 
    } 

    } 
}

更新與鼠標支持

因爲我無法抗拒玩...

'JWindow'基本上就像一個可以顯示在屏幕上的'JPanel'，對嗎？ –

不，不是真的。 'JWindow'更像是一個未裝飾的'JFrame'（'JFrame'從'JWindow'延伸） – MadProgrammer

我知道層次結構，只是給出了一個明示的:)如果你仍然想要更多的Java：http：// stackoverflow.com/questions/14375338/cannot-play-embedded-sound-in-a-jar-file –

起初，我認爲這將是相當微不足道的 - 增加一個鼠標監聽使用addMouseListener將（在任務欄圖標），並使用的mouseEntered（）和mouseExitedEvents（）：

icon.addMouseListener(new MouseAdapter() 
{ 
    @Override 
    public void mouseEntered(MouseEvent e) 
    { 
     System.out.println("Mouse over icon"); 
    } 

    @Override 
    public void mouseExited(MouseEvent e) 
    { 
     System.out.println("Mouse leaving icon"); 
    } 
});

但是，至少在我測試過的平臺上（Windows上的Java 7u10），這不起作用 - 當我將鼠標光標懸停在托盤圖標上時，沒有生成任何事件。做什麼工作是一個MouseMotionListener和addMouseMotionListener方法：

icon.addMouseMotionListener(new MouseMotionAdapter() 
{ 
    @Override 
    public void mouseMoved(MouseEvent e) 
    { 
     System.out.println("Moving..."); 
    } 
});

活動在mouseMoved()產生只有當鼠標移動到圖標。通過一些工作，在收到第一個事件以模擬工具提示時間之後的某個延遲之後，這可以用於顯示JWindow（您可以通過類似於ToolTipManager.sharedInstance().getInitialDelay()的東西獲得平臺的工具提示顯示時間）
