java – 如何将东西添加到系统托盘并添加mouseOver()功能？
作者：互联网
对不起,如果标题含糊不清,但这正是我想要实现的.
这是图标化/最小化的电池保护软件.将鼠标悬停在图标上时,您将看到图片中显示的窗口.
如何在Java中实现？
解决方法:
这使用JPopupMenu显示点击信息,而不是最推荐的方法,因为它很难布局其他组件……但你可以轻松地使用JWindow …
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);
}
}
});
}
}
}
更新了鼠标支持
因为我无法抗拒…
