使用java左键单击任务托盘图标上的打开弹出窗口（菜单）

Question

我正在使用Java中的任务托盘图标，我喜欢打开一个弹出菜单，使用左键单击相同的弹出菜单，因为我打开右键，请帮助我快速响应。

提前致谢...

这是用于右键单击的代码需要在左键单击时显示相同的弹出窗口...不要忘记放置任何图像@“src / img”文件夹，名称为“titleImg.jpg”

只需运行此...这是一个工作示例，但我必须使用左键单击显示相同的弹出窗口

我已经检查了鼠标监听器，它听左键单击托盘图标，但如何显示弹出菜单使用???

你实际缺少的是显示你的PopupMenu的父组件。 实现这一目标的一种方法是使用“隐形”框架（实际上它是可见的，但有0边界和未修饰，所以你看不到它）像这样：

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;
    }
}

从Java 1.7开始，您可以添加以下行以从任务栏中删除应用程序栏：

frame.setType(Type.UTILITY);

Answer 2

你可以将ActionListener添加到TrayIcon ，鼠标double_click可以显示JOptionPane

trayIcon.addActionListener(new ActionListener() {

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

Answer 3

我想你正在寻找一个MouseListener ，它将添加到你的TrayIcon并在单击鼠标上的按钮，移动等时激活。要让它在左键单击时操作，只需查看MouseEvent上的ButtonMasks（ BUTTON1 ）用于鼠标左键单击。

Answer 4

您可以在http://docs.oracle.com/javase/tutorial/uiswing/misc/systemtray.html上阅读官方教程，或查看http://weblogs.java.net/blog/ixmal/archive/2006/05 /using_jpopupmen.html用于替代使用jpopuomenu的解决方案

Answer 5

这应该工作：

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

如果您想要一种不同类型的事件（不仅仅是上面示例中的click事件），请覆盖任何其他方法。
