تضمين JWindow في سطح المكتب باستخدام Java

To create a JWindow that stays on the desktop and remains visible even when you minimize all windows or switch between them, you can use the following approach. However, it’s important to note that manipulating windows at this level can be platform-dependent and may not work reliably on all operating systems or with all desktop environments.

First, you need to get the desktop’s JDesktopPane and add your JWindow to it. Then, you can use a WindowListener to listen for window events and ensure your JWindow remains visible even when other windows are minimized.

Here’s a basic example:

javaCopy code
import javax.swing.*;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

public class DesktopJWindowExample {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            // Create a JWindow
            JWindow window = new JWindow();
            window.setSize(200, 200);
            window.setLocationRelativeTo(null); // Center the window

            // Create a JDesktopPane to hold the JWindow
            JDesktopPane desktopPane = new JDesktopPane();
            desktopPane.add(window);

            // Create a JFrame to hold the JDesktopPane
            JFrame frame = new JFrame("Desktop JWindow Example");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setContentPane(desktopPane);
            frame.setSize(400, 400);
            frame.setVisible(true);

            // Add a WindowListener to the JWindow to keep it visible
            WindowListener windowListener = new WindowAdapter() {
                @Override
                public void windowIconified(WindowEvent e) {
                    window.setVisible(true); // Show the JWindow when iconified
                }

                @Override
                public void windowDeiconified(WindowEvent e) {
                    window.setVisible(true); // Show the JWindow when deiconified
                }
            };
            window.addWindowListener(windowListener);
        });
    }
}

This example creates a JWindow that stays on the desktop and remains visible even when other windows are minimized. Note that the behavior may vary depending on the platform and desktop environment.

لتحقيق هذا الهدف، يمكنك استخدام Java Native Access (JNA) للوصول إلى وظائف نظام التشغيل المناسبة التي تمكنك من تضمين النافذة في سطح المكتب. يمكنك استخدام JNA للوصول إلى وظائف واجهة برمجة التطبيقات الرسومية لنظام التشغيل (مثل Windows API أو X11) وتنفيذ الإجراءات الضرورية.

إليك مثال بسيط باستخدام JNA لنظام Windows لتضمين نافذة JWindow في سطح المكتب:

javaCopy code
import com.sun.jna.Native;
import com.sun.jna.Pointer;
import com.sun.jna.platform.win32.User32;
import com.sun.jna.platform.win32.WinDef;
import com.sun.jna.platform.win32.WinUser;

import javax.swing.*;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

public class DesktopJWindowExample {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            // Create a JWindow
            JWindow window = new JWindow();
            window.setSize(200, 200);
            window.setLocationRelativeTo(null); // Center the window

            // Create a JDesktopPane to hold the JWindow
            JDesktopPane desktopPane = new JDesktopPane();
            desktopPane.add(window);

            // Create a JFrame to hold the JDesktopPane
            JFrame frame = new JFrame("Desktop JWindow Example");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setContentPane(desktopPane);
            frame.setSize(400, 400);
            frame.setVisible(true);

            // Add a WindowListener to the JWindow to keep it visible
            WindowListener windowListener = new WindowAdapter() {
                @Override
                public void windowIconified(WindowEvent e) {
                    window.setVisible(true); // Show the JWindow when iconified
                }

                @Override
                public void windowDeiconified(WindowEvent e) {
                    window.setVisible(true); // Show the JWindow when deiconified
                }
            };
            window.addWindowListener(windowListener);

            // Use JNA to set the JWindow as the owner of the desktop
            setWindowAsDesktopOwner(window);
        });
    }

    private static void setWindowAsDesktopOwner(Window window) {
        if (System.getProperty("os.name").startsWith("Windows")) {
            // Get the HWND of the window
            WinDef.HWND hwnd = new WinDef.HWND(Native.getWindowPointer(window));

            // Get the HWND of the desktop
            WinDef.HWND desktopHwnd = User32.INSTANCE.GetDesktopWindow();

            // Set the owner of the window to the desktop
            User32.INSTANCE.SetWindowLong(hwnd, WinUser.GWL_HWNDPARENT, new WinDef.HWND(Pointer.nativeValue(desktopHwnd.getPointer())));
        }
    }
}

يرجى ملاحظة أن هذا المثال يستخدم JNA، والذي يمكن أن يكون معقدًا للمبتدئين، ويعتمد على واجهة برمجة التطبيقات الخاصة بنظام Windows. للحصول على نتائج مماثلة لأنظمة تشغيل أخرى، قد تحتاج إلى استخدام تقنيات مختلفة.
