Question

我想使用JPopupMenu创建System Tray但是它只接受awt的PopupMenu。

我使用以下代码：

package UserInterface;

import java.awt.AWTException;
import java.awt.Font;
import java.awt.Image;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.TrayIcon;
import java.net.URL;

import javax.swing.ImageIcon;
import javax.swing.JCheckBoxMenuItem;
import javax.swing.JMenuItem;
import javax.swing.JPopupMenu;

public class StartBarMenu extends JPopupMenu {
    private static final long serialVersionUID = 1L;

    public StartBarMenu() {
        JMenuItem mntmTwincloud = new JMenuItem("Cloud");
        mntmTwincloud.setFont(new Font("Segoe Print", Font.BOLD, 14));
        this.add(mntmTwincloud);

        JMenuItem mntmCapacity = new JMenuItem("X GB of Y GB used");
        this.add(mntmCapacity);

        this.addSeparator();

        JMenuItem mntmOpenTwinCloud = new JMenuItem("Open Cloud folder");
        this.add(mntmOpenTwinCloud);

        JCheckBoxMenuItem chckbxmntmEnableAutoSync = new JCheckBoxMenuItem(
                "Enable Auto Sync");
        this.add(chckbxmntmEnableAutoSync);
        chckbxmntmEnableAutoSync.setState(true);

        JMenuItem mntmShareFile = new JMenuItem("Share File");
        this.add(mntmShareFile);

        JMenuItem mntmLogOut = new JMenuItem("Log Out");
        this.add(mntmLogOut);

        JMenuItem mntmExit = new JMenuItem("Exit");
        this.add(mntmExit);

        addPopUpToTry();
    }

    private void addPopUpToTry() {
        final SystemTray tray = SystemTray.getSystemTray();
        final TrayIcon trayIcon = new TrayIcon(createImage("bulb.gif", "tray icon"));
        trayIcon.setPopupMenu(this); // Error

        trayIcon.setImageAutoSize(true);

        try {
            tray.add(trayIcon);
        } catch (AWTException e) {
            System.out.println("TrayIcon could not be added.");
            return;
        }
    }

    protected static Image createImage(String path, String description) {
        URL imageURL = TrayIconDemo.class.getResource(path);

        if (imageURL == null) {
            System.err.println("Resource not found: " + path);
            return null;
        } else {
            return (new ImageIcon(imageURL, description)).getImage();
        }
    }
}

但是，trayIcon.setPopupMenu(this);会出现以下错误。

TrayIcon类型中的方法setPopupMenu（PopupMenu）不是适用于参数（JPopupMenu）

当我将JPopupMenu更改为awt PopupMenu并进行其他必要的更改时，我可以成功运行代码。但我不想使用PopupMenu。

如何使用JPopupMenu并将其放入系统托盘？

无法将swing的JPopupMenu放入SystemTray
