+
+ @section taskbaricon_xnote X Window System Note
+
+ Under X Window System, the window manager must support either the
+ "System Tray Protocol" (see http://freedesktop.org/wiki/Specifications/systemtray-spec)
+ by freedesktop.org (WMs used by modern desktop environments such as GNOME >= 2,
+ KDE >= 3 and XFCE >= 4 all do) or the older methods used in GNOME 1.2 and KDE 1 and 2.
+
+ If it doesn't, the icon will appear as a toplevel window on user's desktop.
+ Because not all window managers have system tray, there's no guarantee that
+ wxTaskBarIcon will work correctly under X Window System and so the applications
+ should use it only as an optional component of their user interface.
+ The user should be required to explicitly enable the taskbar icon on Unix,
+ it shouldn't be on by default.
+
+ @beginEventEmissionTable{wxTaskBarIconEvent}
+ Note that not all ports are required to send these events and so it's better
+ to override wxTaskBarIcon::CreatePopupMenu() if all that the application does
+ is that it shows a popup menu in reaction to mouse click.
+ @event{EVT_TASKBAR_MOVE(func)}
+ Process a @c wxEVT_TASKBAR_MOVE event.
+ @event{EVT_TASKBAR_LEFT_DOWN(func)}
+ Process a @c wxEVT_TASKBAR_LEFT_DOWN event.
+ @event{EVT_TASKBAR_LEFT_UP(func)}
+ Process a @c wxEVT_TASKBAR_LEFT_UP event.
+ @event{EVT_TASKBAR_RIGHT_DOWN(func)}
+ Process a @c wxEVT_TASKBAR_RIGHT_DOWN event.
+ @event{EVT_TASKBAR_RIGHT_UP(func)}
+ Process a @c wxEVT_TASKBAR_RIGHT_UP event.
+ @event{EVT_TASKBAR_LEFT_DCLICK(func)}
+ Process a @c wxEVT_TASKBAR_LEFT_DCLICK event.
+ @event{EVT_TASKBAR_RIGHT_DCLICK(func)}
+ Process a @c wxEVT_TASKBAR_RIGHT_DCLICK event.
+ @event{EVT_TASKBAR_CLICK(func)}
+ This is a synonym for either EVT_TASKBAR_RIGHT_DOWN or UP depending on
+ the platform, use this event macro to catch the event which should result
+ in the menu being displayed on the current platform.
