在任务栏图标上使用java点击左键打开弹出窗口(菜单)

我正在使用 Java中的任务托盘图标,我喜欢使用左键单击弹出菜单打开一个弹出菜单,我右键单击打开,请快速回复.

提前致谢…

这里是代码工作的右键点击需要显示相同的弹出窗口左键单击…
不要忘记放置任何图像@“src / img”文件夹,名称为“titleImg.jpg”

只是运行这个…这是一个工作的例子,但我必须使用左键显示相同的弹出窗口

我已经检查了鼠标监听器,它听到左键单击托盘图标,但如何显示弹出式菜单使用？

package com.abc.dao;

import java.awt.Menu;
import java.awt.MenuItem;
import java.awt.PopupMenu;

public class MyTaskTray {

        //Check the SystemTray is supported
        if (!SystemTray.isSupported()) {
            System.out.println("SystemTray is not supported");
            return;
        }
        final PopupMenu popup = new PopupMenu();

                new TrayIcon(Toolkit.getDefaultToolkit().getImage(new java.io.File("").getAbsolutePath()+"/bin/img/titleImg.jpg"),"Library Drop");
        final SystemTray tray = SystemTray.getSystemTray();

        // Create a pop-up menu components
        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);

        trayIcon.setPopupMenu(popup);

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

    }
}

解决方法

您实际缺少的是显示您的PopupMenu的父组件.实现这一点的一个方法是使用“隐形”框架(实际上它是可见的,但是具有0边界并且未装饰,所以你看不到)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,您可以添加以下行来从任务栏中删除应用程序栏：

frame.setType(Type.UTILITY);

在任务栏图标上使用java点击左键打开弹出窗口(菜单)
