闪烁托盘图标

• 在某些情况下，以输出闪烁的图标更改图标没有问题

• 创建一个

  Arrays of BufferedImage

  或队列

• 在所需事件上启动Swing计时器，并在一段时间内更改

  BufferedImage

  或图标

• 并停止

  Swing Timer

  一段时间后残留或添加

  ActionListener

  到

  Message

  ，另一种方式可以是确定

  LEFT

  或

  RIGHT

  从鼠标按钮

  MouseListener

  （用于

  Icon

  在

  System Tray

  ）一个用于停止

  Timer

  ，对于第二

  JPopup

编辑

例如，正如我提到的，您可以添加ActionListener或MouseListener，在那里可以停止Swing
Timer
