java托盤
⑴ 我要用java做一個系統托盤，點最小化按鈕，要怎麼監聽或者給我來個系統托盤的全代碼 不要網上復制的
以下代碼直接即可運行，注意修改一下托盤圖標的文件路徑！
/////////////////////////////////////////////////////////////////////
import java.awt.AWTException;
import java.awt.Image;
import java.awt.MenuItem;
import java.awt.PopupMenu;
import java.awt.SystemTray;
import java.awt.Toolkit;
import java.awt.TrayIcon;
import java.awt.TrayIcon.MessageType;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JFrame;
public class SystemTrayTest extends JFrame {
public SystemTrayTest() throws AWTException {
this.setSize(500, 300);
this.setLocation(100, 50);
//判斷當前操作系統是否支持托盤
if (SystemTray.isSupported()) {
//獲取系統托盤
SystemTray tray = SystemTray.getSystemTray();
//托盤的右鍵菜單
PopupMenu menu = new PopupMenu();
//退出菜單
MenuItem exitItem = new MenuItem("Exit");
exitItem.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
//顯示主窗口菜單
MenuItem showItem = new MenuItem("Show the main frame");
showItem.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
SystemTrayTest.this.setVisible(true);
}
});
//關於菜單（未注冊事件）
MenuItem aboutItem = new MenuItem("about...");
menu.add(exitItem);
menu.add(showItem);
menu.add(aboutItem);
//托盤的標題
String title = "Hey,Java!";
//托盤圖標
Image img = Toolkit.getDefaultToolkit().getImage("icon.jpg");
//實例化TrayIcon對象
TrayIcon icon = new TrayIcon(img, title, menu);
//托盤添加滑鼠事件
icon.addMouseListener(new MouseAdapter() {
public void mouseReleased(MouseEvent e) {
SystemTrayTest.this.setVisible(true);
}
});
tray.add(icon);
icon.displayMessage("Hello!", "this is my DIY SystemTray!",
MessageType.INFO);// 運行程序的時候右下角會提示信息
}
}
public static void main(String[] args) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
try {
new SystemTrayTest().setVisible(true);
} catch (AWTException e) {
e.printStackTrace();
}
}
});
}
}
⑵ java應用程序系統托盤的問題
演示程序，程序啟動後會在托盤處顯示一個黑色方塊代表圖標，滑鼠移上去會有提示，右鍵點擊會有菜單。
import java.awt.*;
import java.awt.event.*;
import java.awt.image.BufferedImage;
import javax.swing.JOptionPane;
public class TrayIconTest {
public static void main(String[] args) throws Exception {
TrayIcon ti = new TrayIcon(new BufferedImage(16, 16, 1));
ti.setImageAutoSize(true);
if (SystemTray.isSupported()) {
SystemTray.getSystemTray().add(ti);
ti.setToolTip("Trayicon test.");
ActionListener l = new ActionListener() {
public void actionPerformed(ActionEvent e) {
String ac = e.getActionCommand();
if (ac.equalsIgnoreCase("action 1")) {
System.out.println("Menu 1 performed.");
} else if (ac.equalsIgnoreCase("action 2")) {
System.out.println("Menu 2 performed.");
JOptionPane.showMessageDialog(null, "Hello world.");
} else if (ac.equalsIgnoreCase("action 3")) {
System.out.println("Menu exit performed.");
System.exit(0);
}
}
};
PopupMenu pm = new PopupMenu();
MenuItem mi = new MenuItem("Menu 1");
mi.setActionCommand("action 1");
mi.addActionListener(l);
pm.add(mi);
mi = new MenuItem("Menu 2");
mi.setActionCommand("action 2");
mi.addActionListener(l);
pm.add(mi);
mi = new MenuItem("Menu exit");
mi.setActionCommand("action 3");
mi.addActionListener(l);
pm.add(mi);
ti.setPopupMenu(pm);
}
}
}
⑶ JAVA 系統托盤 圖片不顯示
可能是圖沒有了，setImageAutoSize(true)把這個設置下能不能看到圖片的，再沒有那就指定是圖沒拿到了。
⑷ java swing 系統托盤問題

哦

托盤圖標，建
議使用較小的圖片

final JFrame frame=new JFrame();
JPanel jp=new JPanel();
frame.add(jp);
frame.setSize(320,240);
frame.setLocationRelativeTo(null);
frame.setResizable(false);
frame.setIconImage(img);//
設置窗口左上角的圖標
frame.setVisible(true);
Tray=SystemTray.getSystemTray();//
獲得系統托盤實例
//
創建系統托盤的右鍵彈出菜單
PopupMenu pm=new PopupMenu();
MenuItem mi0=new MenuItem("Open");
MenuItem mi1=new MenuItem("Close");
pm.add(mi0);
pm.add(mi1);
trayIcon=new TrayIcon(img,"",pm);//
創建托盤圖標實例
trayIcon.setImageAutoSize(true);//
圖標自動適應托盤，也就是說它自動
改變大小
trayIcon.setToolTip(" ");//
設置提示語
//
添加系統托盤圖標
frame.addWindowListener(new
WindowAdapter()
{//
當「關閉」窗口時，最
小化到系統托盤
public void windowClosing(WindowEvent e) {
try {
Tray.add(trayIcon);
} catch (AWTException exc) {
exc.printStackTrace();
}
}});
mi0.addActionListener(new ActionListener(){ //
右鍵彈出菜單的事件
監聽
public void actionPerformed(ActionEvent e) {
frame.setExtendedState(JFrame.NORMAL);
frame.setVisible(true);
Tray.remove(trayIcon);
}
});
mi1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
System.exit(0);
Tray.remove(trayIcon);//
退出程序，移出系統托盤處的圖標
