如何在关闭应用程序后显示我创建的java应用程序? 我的意思是我想要关闭我制作的应用程序,之后它仍然在后台进程(托盘)上运行,我做了,但是如何在双击托盘图标后再次显示应用程序(弹出)? 有人可以帮我吗?
public MainMenu(String access) {
this.access = access;
initComponents();
customInit();
this.setLocationRelativeTo(null);
this.setExtendedState(this.MAXIMIZED_BOTH);
requestJobList("ALL");
setDefaultCloseOperation(HIDE_ON_CLOSE);
createReminder();
}
private void customInit(){
joblistTable.setCellSelectionEnabled(rootPaneCheckingEnabled);
}
private void createReminder(){
String icoPath = "C:/Users/user/Documents/NetBeansProjects/MOADesktopBaru/src/com/mayora/image/MOA.PNG";
if(!SystemTray.isSupported()){
System.out.println("System tray is not supported !!! ");
return ;
}
//get the systemTray of the system
SystemTray systemTray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage(icoPath);
//popupmenu
PopupMenu trayPopupMenu = new PopupMenu();
//1t menuitem for popupmenu
MenuItem setting = new MenuItem("Setting");
setting.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
SettingFrame SF = new SettingFrame ();
jDesktopPane.add(SF);
SF.show();
}
});
trayPopupMenu.add(setting);
//2nd menuitem of popupmenu
MenuItem close = new MenuItem("Close");
close.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
trayPopupMenu.add(close);
//setting tray icon
TrayIcon trayIcon = new TrayIcon(image, "MOA Desktop", trayPopupMenu);
//adjust to default size as per system recommendation
trayIcon.setImageAutoSize(true);
trayIcon.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (e.getClickCount() == 2)
{
initComponents();
customInit();
setExtendedState(MAXIMIZED_BOTH);
requestJobList("ALL");
setDefaultCloseOperation(EXIT_ON_CLOSE);
}
}
});
try{
systemTray.add(trayIcon);
}catch(AWTException awtException){
awtException.printStackTrace();
}
}

我认为setDefaultCloseOperation(EXIT_ON_CLOSE);
不应放在托盘图标监听器内。
要想通过双击其托盘图标再次显示您的应用,只需在此行中添加mouseClicked()
方法:
setVisible(true);
请注意,您再次看到的是JFrame,因此如果您需要指定它,只需在setVisible(true)
方法之前添加它即可。顺便说一句,由于应用程序已经执行(在后台),您不需要再次调用initComponents()
方法。
另一个建议,不要使用mouseClicked()
方法。请改用MouseListener Interface中的mousePressed()
。为什么?有时您点击太快以至于应用检测到mouseDragged
事件,因此点击不计算在内。如果您使用mousePressed()
,则可以保证它同时检测到两次点击。
