如何做到这一点？

public class TransparentWindow extends JFrame { public TransparentWindow() { initComponents(); } @SuppressWarnings("unchecked") private void initComponents() { setExtendedState(Frame.MAXIMIZED_BOTH); setResizable(false); setUndecorated(true); setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE); setAlwaysOnTop(true); System.setProperty("sun.java2d.noddraw", "true"); WindowUtils.setWindowTransparent(this, true); WindowUtils.setWindowAlpha(this, 0.6f); } public static void main(String[] args) { new TransparentWindow().setVisible(true); } }

推荐答案

我似乎已经找到了答案，只需将行 setVisible（false）; 放入注释中，您将看到实际的程序，UNCOMMENT该行看不到任何痕迹，据我所知，Java程序正在某个地方运行，直到您不会手动将图标添加到系统托盘中。此外，如何从任务管理器中删除您的应用程序仍然存在问题，但您可以删除所述图标，如您在问题中所指出的那样。

I just seems to have found the answer, just put the line setVisible(false); into comments and you will see the actual program, UNCOMMENT the line to see no trace is left, as far as I can see, that the Java Program is running somewhere, until you won't add the icon to your system tray, manually. Moreover how to remove your Application from Task Manager that question still remains, though you can remove the said icon, as pointed by you in your question.

import javax.swing.*; public class TransparentWindow extends JFrame { public TransparentWindow() { initComponents(); } @SuppressWarnings("unchecked") private void initComponents() { setExtendedState(JFrame.MAXIMIZED_BOTH); setResizable(false); setUndecorated(true); setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE); setAlwaysOnTop(true); setOpacity(0.8f); setSize(200, 200); //System.setProperty("sun.java2d.noddraw", "true"); //WindowUtils.setWindowTransparent(this, true); //WindowUtils.setWindowAlpha(this, 0.6f); setVisible(true); setVisible(false); JOptionPane.showMessageDialog(this, "It is working!", "Guess : ", JOptionPane.INFORMATION_MESSAGE); } public static void main(String[] args) { TransparentWindow tw = new TransparentWindow(); } }

以下是运行此程序时桌面的快照，请参阅任务栏
