\section{\class{wxTaskBarIcon}}\label{wxtaskbaricon}

This class represents a taskbar icon, appearing in the `system tray' and
responding to mouse clicks. An icon has an optional tooltip. This class is only
supported under Windows 95/NT and in X Window System ports (wxGTK, wxMotif,
wxX11). 

\wxheading{X Window System Note}

Under X Window System, the window manager must support either
the \urlref{System Tray Protocol by freedesktop.org}{http://freedesktop.org/Standards/systemtray-spec}
(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.

\wxheading{Event handling}

To process input from a taskbar icon, use the following event handler macros to direct input to member
functions that take a wxTaskBarIconEvent argument.

\membersection{wxTaskBarIcon::wxTaskBarIcon}\label{wxtaskbariconconstr}

\func{}{wxTaskBarIcon}{\void}

Default constructor.

\membersection{wxTaskBarIcon::\destruct{wxTaskBarIcon}}

\func{}{\destruct{wxTaskBarIcon}}{\void}

Destroys the wxTaskBarIcon object, removing the icon if not already removed.

\membersection{wxTaskBarIcon::IsIconInstalled}\label{wxtaskbariconisiconinstalled}

\func{bool}{IsIconInstalled}{\void}

Returns true if \helpref{SetIcon}{wxtaskbariconseticon} was called with no subsequent \helpref{RemoveIcon}{wxtaskbariconremoveicon}.

\membersection{wxTaskBarIcon::IsOk}\label{wxtaskbariconisok}

\func{bool}{IsOk}{\void}

Returns true if the object initialized successfully.

\membersection{wxTaskBarIcon::PopupMenu}\label{wxtaskbariconpopupmenu}

\func{bool}{PopupMenu}{\param{wxMenu*}{ menu}}

Pops up a menu at the current mouse position. The events can be handled by
a class derived from wxTaskBarIcon.

\membersection{wxTaskBarIcon::RemoveIcon}\label{wxtaskbariconremoveicon}

\func{bool}{RemoveIcon}{\void}

Removes the icon previously set with \helpref{SetIcon}{wxtaskbariconseticon}.

\membersection{wxTaskBarIcon::SetIcon}\label{wxtaskbariconseticon}

\func{bool}{SetIcon}{\param{const wxIcon\&}{ icon}, \param{const wxString\& }{tooltip}}

Sets the icon, and optional tooltip text.
