+    This class represents a taskbar icon.
+    A taskbar icon is an icon that appears in the 'system tray' and responds to
+    mouse clicks, optionally with a tooltip above it to help provide information.
+
+
+    @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)}
