Tony MOREHEN reported a new bug.

Summary
-------

X11 Systray behaves strangely under GTK or QT5

Type             : Bug
Priority         : Medium
Gambas version   : Unknown
Product          : Unknown


Description
-----------

Under GTK, Systray icons must be placed using absolute screen coordinates, not relative to the proper window (as set in Systray.Show(Handle).  The background of transparent icons is correct ie set to the appropriate window background.

Under GTK 3 Systray icons also must be placed according to absolute screen coordinates.  Also, their backgrounds correspond to the root window background.

Under QT5 no icons are shown accompanied by the following error messages:
QXcbWindows unhandled client message: _NET_SYSTEMTRAY_OPCODE
QXcbWindows unhandled client message: _NET_WM_DESKTOP
QXcbWindows unhandled client message: _NET_SYSTEMTRAY_OPCODE

QT4 behaves correctly.
