title: don't show on panel
body: <p>I am trying to write a simple aplication (a continuously changing label on a window on the upper left side of the screen) and I don't want it to be seen on panel but only on system tray.Because it will run for a long time. How can I do that? Thanks.</p>
  
  <p>PS: I am using python and pyqt on Linux. I tried SplashScreen but when I clicked on the window it disapears. I have a contexmenu on the window, so I must click on it.!</p>
