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

3This 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.

7Under X Window System, the window manager must support either
8the \urlref{System Tray Protocol by freedesktop.org}{http://freedesktop.org/Standards/systemtray-spec}
9(WMs used by modern desktop environments such as GNOME >= 2, KDE
10>= 3 and XFCE >= 4 all do) or the older methods used in GNOME 1.2 and
11KDE 1 and 2. If it doesn't, the icon will appear as a toplevel window on
12user's desktop.
13
14Because not all window managers have system tray, there's no guarantee that
15wxTaskBarIcon will work correctly under X Window System and so the applications
16should use it only as an optional component of their user interface. The user
17should be required to explicitly enable the taskbar icon on Unix, it shouldn't
18be on by default.

34\wxheading{Event handling}
35
36To process input from a taskbar icon, use the following event handler macros to direct input to member
37functions that take a wxTaskBarIconEvent argument. Note that not all ports are
38required to send these events and so it's better to override
39\helpref{CreatePopupMenu}{wxtaskbariconcreatepopupmenu} if all that
40the application does is that it shows a popup menu in reaction to mouse click.

66\membersection{wxTaskBarIcon::wxTaskBarIcon}\label{wxtaskbariconctor}
67
68\func{}{wxTaskBarIcon}{\void}
69
70Default constructor.
71
72\membersection{wxTaskBarIcon::\destruct{wxTaskBarIcon}}\label{wxtaskbaricondtor}
73
74\func{}{\destruct{wxTaskBarIcon}}{\void}
75
76Destroys the wxTaskBarIcon object, removing the icon if not already removed.
77
78\membersection{wxTaskBarIcon::CreatePopupMenu}\label{wxtaskbariconcreatepopupmenu}
79
80\func{virtual wxMenu*}{CreatePopupMenu}{\void}
81
82This method is called by the library when the user requests popup menu
83(on Windows and Unix platforms, this is when the user right-clicks the icon).
84Override this function in order to provide popup menu associated with the icon.
85
86If CreatePopupMenu returns NULL (this happens by default),
87no menu is shown, otherwise the menu is
88displayed and then deleted by the library as soon as the user dismisses it.
89The events can be handled by a class derived from wxTaskBarIcon.
90
91\membersection{wxTaskBarIcon::IsIconInstalled}\label{wxtaskbariconisiconinstalled}
92
93\func{bool}{IsIconInstalled}{\void}
94
95Returns true if \helpref{SetIcon}{wxtaskbariconseticon} was called with no subsequent \helpref{RemoveIcon}{wxtaskbariconremoveicon}.
96
97\membersection{wxTaskBarIcon::IsOk}\label{wxtaskbariconisok}
98
99\func{bool}{IsOk}{\void}
100
101Returns true if the object initialized successfully.
102
103\membersection{wxTaskBarIcon::PopupMenu}\label{wxtaskbariconpopupmenu}
104
105\func{bool}{PopupMenu}{\param{wxMenu*}{ menu}}
106
107Pops up a menu at the current mouse position. The events can be handled by
108a class derived from wxTaskBarIcon.
109
110\wxheading{Note}
111
112It is recommended to override
113\helpref{CreatePopupMenu}{wxtaskbariconcreatepopupmenu}
114callback instead of calling this method from event handler, because some
115ports (e.g. wxCocoa) may not implement PopupMenu and mouse click events at all.
116
117\membersection{wxTaskBarIcon::RemoveIcon}\label{wxtaskbariconremoveicon}
118
119\func{bool}{RemoveIcon}{\void}
120
121Removes the icon previously set with \helpref{SetIcon}{wxtaskbariconseticon}.
122
123\membersection{wxTaskBarIcon::SetIcon}\label{wxtaskbariconseticon}
124
125\func{bool}{SetIcon}{\param{const wxIcon\&}{ icon}, \param{const wxString\& }{tooltip}}
126
127Sets the icon, and optional tooltip text.
