valid - ¿Cómo pongo una aplicación Java en la bandeja del sistema?

porque no puedo verificar la version de java

Question

Tengo un pequeño panel de control, solo una pequeña aplicación que hice. Me gustaría minimizar / poner el panel de control arriba / abajo con los sistemas, junto con la duración de la batería, la fecha, las redes, etc.

¿Alguien que pueda darme una pista, un enlace a un tutorial o algo para leer?

Answer 1

Este es el código que puede usar para acceder y personalizar la bandeja del sistema:

final TrayIcon trayIcon;

if (SystemTray.isSupported()) {

SystemTray tray = SystemTray.getSystemTray();
Image image = Toolkit.getDefaultToolkit().getImage("tray.gif");

MouseListener mouseListener = new MouseListener() {

    public void mouseClicked(MouseEvent e) {
        System.out.println("Tray Icon - Mouse clicked!");                 
    }

    public void mouseEntered(MouseEvent e) {
        System.out.println("Tray Icon - Mouse entered!");                 
    }

    public void mouseExited(MouseEvent e) {
        System.out.println("Tray Icon - Mouse exited!");                 
    }

    public void mousePressed(MouseEvent e) {
        System.out.println("Tray Icon - Mouse pressed!");                 
    }

    public void mouseReleased(MouseEvent e) {
        System.out.println("Tray Icon - Mouse released!");                 
    }
};

ActionListener exitListener = new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        System.out.println("Exiting...");
        System.exit(0);
    }
};

PopupMenu popup = new PopupMenu();
MenuItem defaultItem = new MenuItem("Exit");
defaultItem.addActionListener(exitListener);
popup.add(defaultItem);

trayIcon = new TrayIcon(image, "Tray Demo", popup);

ActionListener actionListener = new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        trayIcon.displayMessage("Action Event", 
            "An Action Event Has Been Performed!",
            TrayIcon.MessageType.INFO);
    }
};

trayIcon.setImageAutoSize(true);
trayIcon.addActionListener(actionListener);
trayIcon.addMouseListener(mouseListener);

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

} else {

//  System Tray is not supported

}

Es muy sencillo

import java.awt.*;
import java.awt.event.*;
import javax.swing.JOptionPane;

public class SystemTrayDemo{

//start of main method
public static void main(String []args){
    //checking for support
    if(!SystemTray.isSupported()){
        System.out.println("System tray is not supported !!! ");
        return ;
    }
    //get the systemTray of the system
    SystemTray systemTray = SystemTray.getSystemTray();

    //get default toolkit
    //Toolkit toolkit = Toolkit.getDefaultToolkit();
    //get image 
    //Toolkit.getDefaultToolkit().getImage("src/resources/busylogo.jpg");
    Image image = Toolkit.getDefaultToolkit().getImage("src/images/1.gif");

    //popupmenu
    PopupMenu trayPopupMenu = new PopupMenu();

    //1t menuitem for popupmenu
    MenuItem action = new MenuItem("Action");
    action.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            JOptionPane.showMessageDialog(null, "Action Clicked");          
        }
    });     
    trayPopupMenu.add(action);

    //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, "SystemTray Demo", trayPopupMenu);
    //adjust to default size as per system recommendation 
    trayIcon.setImageAutoSize(true);

    try{
        systemTray.add(trayIcon);
    }catch(AWTException awtException){
        awtException.printStackTrace();
    }
    System.out.println("end of main");

}//end of main

}//end of class

Establezca la ruta adecuada para la imagen y luego ejecute el programa. ty :)

A partir de Java 6, esto es compatible con las clases SystemTray y TrayIcon . SystemTray tiene un ejemplo bastante extenso en sus Javadocs:

TrayIcon trayIcon = null;
if (SystemTray.isSupported()) {
    // get the SystemTray instance
    SystemTray tray = SystemTray.getSystemTray();
    // load an image
    Image image = Toolkit.getDefaultToolkit().getImage("your_image/path_here.gif");
    // create a action listener to listen for default action executed on the tray icon
    ActionListener listener = new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            // execute default action of the application
            // ...
        }
    };
    // create a popup menu
    PopupMenu popup = new PopupMenu();
    // create menu item for the default action
    MenuItem defaultItem = new MenuItem(...);
    defaultItem.addActionListener(listener);
    popup.add(defaultItem);
    /// ... add other items
    // construct a TrayIcon
    trayIcon = new TrayIcon(image, "Tray Demo", popup);
    // set the TrayIcon properties
    trayIcon.addActionListener(listener);
    // ...
    // add the tray image
    try {
        tray.add(trayIcon);
    } catch (AWTException e) {
        System.err.println(e);
    }
    // ...
} else {
    // disable tray option in your application or
    // perform other actions
    ...
}
// ...
// some time later
// the application state has changed - update the image
if (trayIcon != null) {
    trayIcon.setImage(updatedImage);
}
// ...
