title: How to diplay system tray icon using Mono (Linux)?
body: <p>I am using GTK# 2.12 as it is described <a href="http://www.mono-project.com/docs/gui/gtksharp/widgets/notification-icon/" rel="nofollow">here</a>.</p>
  
  <p>But when I use a PNG image with transparency, KDE does not want to redraw the transparent parts of the image. So, I see the old bitmap (not panel bar) on transparent parts of image.</p>
  
  <p>I guess that it can be bug inside GTK# itself. So, I am looking for a new way to display system tray icons using mono. Maybe some library over QSystemTrayIcon could do it. Ideally, it should be cross-platform. So, on Windows, it should also be displayed.</p>
  
  <p>Alternatively, I can try to implement platform invoke for Linux version (maybe best option). But please give me some example... I am new for Qt and platform invocation in Linux.</p>
