title: How does (Gnome) Desktop Notification work?
body: <p>For example<br>
  <img src="https://www.gnome.org/wp-content/uploads/2013/03/message-tray-chat-3-8-420x236.png" alt="gnome chat"></p>
  
  <p>Or the Filezilla Notification "Upload complete!".</p>
  
  <p>How can i use it in my C++ Application? I have searched at developer.gnome.org and found <a href="https://developer.gnome.org/notification-spec/" rel="nofollow noreferrer">this</a> and <a href="http://standards.freedesktop.org/startup-notification-spec/startup-notification-latest.txt" rel="nofollow noreferrer">this</a> but they were not very helpful.</p>
