使用java左鍵單擊任務托盤圖標上的打開彈出窗口（菜單）

Question

我正在使用Java中的任務托盤圖標，我喜歡打開一個彈出菜單，使用左鍵單擊相同的彈出菜單，因為我打開右鍵，請幫助我快速響應。

提前致謝...

這是用於右鍵單擊的代碼需要在左鍵單擊時顯示相同的彈出窗口...不要忘記放置任何圖像@“src / img”文件夾，名稱為“titleImg.jpg”

只需運行此...這是一個工作示例，但我必須使用左鍵單擊顯示相同的彈出窗口

我已經檢查了鼠標監聽器，它聽左鍵單擊托盤圖標，但如何顯示彈出菜單使用???

你實際缺少的是顯示你的PopupMenu的父組件。 實現這一目標的一種方法是使用“隱形”框架（實際上它是可見的，但有0邊界和未修飾，所以你看不到它）像這樣：

import java.awt.AWTException;
import java.awt.CheckboxMenuItem;
import java.awt.Frame;
import java.awt.Menu;
import java.awt.MenuItem;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.Toolkit;
import java.awt.TrayIcon;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.net.MalformedURLException;
import java.net.URL;

public class MyTaskTray {
    public static void main(String arg[]) throws MalformedURLException {
        final Frame frame = new Frame("");
        frame.setUndecorated(true);
        // Check the SystemTray is supported
        if (!SystemTray.isSupported()) {
            System.out.println("SystemTray is not supported");
            return;
        }
        final TrayIcon trayIcon = new TrayIcon(Toolkit.getDefaultToolkit().getImage(
                new URL("http://home.comcast.net/~supportcd/Icons/Java_Required.jpg")), "Library Drop");
        final SystemTray tray = SystemTray.getSystemTray();

        // Create a pop-up menu components
        final PopupMenu popup = createPopupMenu();
        trayIcon.setPopupMenu(popup);
        trayIcon.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                if (e.getButton() == MouseEvent.BUTTON1) {
                    frame.add(popup);
                    popup.show(frame, e.getXOnScreen(), e.getYOnScreen());
                }
            }
        });
        try {
            frame.setResizable(false);
            frame.setVisible(true);
            tray.add(trayIcon);
        } catch (AWTException e) {
            System.out.println("TrayIcon could not be added.");
        }

    }

    protected static PopupMenu createPopupMenu() {
        final PopupMenu popup = new PopupMenu();
        MenuItem aboutItem = new MenuItem("About");
        CheckboxMenuItem cb1 = new CheckboxMenuItem("Set auto size");
        CheckboxMenuItem cb2 = new CheckboxMenuItem("Set tooltip");
        Menu displayMenu = new Menu("Display");
        MenuItem errorItem = new MenuItem("Error");
        MenuItem warningItem = new MenuItem("Warning");
        MenuItem infoItem = new MenuItem("Info");
        MenuItem noneItem = new MenuItem("None");
        MenuItem exitItem = new MenuItem("Exit");
        // Add components to pop-up menu
        popup.add(aboutItem);
        popup.addSeparator();
        popup.add(cb1);
        popup.add(cb2);
        popup.addSeparator();
        popup.add(displayMenu);
        displayMenu.add(errorItem);
        displayMenu.add(warningItem);
        displayMenu.add(infoItem);
        displayMenu.add(noneItem);
        popup.add(exitItem);
        return popup;
    }
}

從Java 1.7開始，您可以添加以下行以從任務欄中刪除應用程序欄：

frame.setType(Type.UTILITY);

Answer 2

你可以將ActionListener添加到TrayIcon ，鼠標double_click可以顯示JOptionPane

trayIcon.addActionListener(new ActionListener() {

   @Override
   public void actionPerformed(ActionEvent e) {
       JOptionPane.showMessageDialog(null, "This dialog box is run from System Tray");
   }
});

Answer 3

我想你正在尋找一個MouseListener ，它將添加到你的TrayIcon並在單擊鼠標上的按鈕，移動等時激活。要讓它在左鍵單擊時操作，只需查看MouseEvent上的ButtonMasks（ BUTTON1 ）用於鼠標左鍵單擊。

Answer 4

您可以在http://docs.oracle.com/javase/tutorial/uiswing/misc/systemtray.html上閱讀官方教程，或查看http://weblogs.java.net/blog/ixmal/archive/2006/05 /using_jpopupmen.html用於替代使用jpopuomenu的解決方案

Answer 5

這應該工作：

trayIcon.addMouseListener(new MouseAdapter() {
    @Override
    public void mouseClicked(MouseEvent e) {
        JOptionPane.showMessageDialog(null, "This shows after a left-click on tray icon");
    }
});

如果您想要一種不同類型的事件（不僅僅是上面示例中的click事件），請覆蓋任何其他方法。
