3This class represents a taskbar icon, appearing in the `system tray' and
4responding to mouse clicks. An icon has an optional tooltip. This class is only
5supported under Windows 95/NT and in X Window System ports (wxGTK, wxMotif,
6wxX11).

10Under X Window System, the window manager must support either
11the \urlref{System Tray Protocol by freedesktop.org}{http://freedesktop.org/Standards/systemtray-spec}
12(WMs used by modern desktop environments such as GNOME >= 2, KDE
13>= 3 and XFCE >= 4 all do) or the older methods used in GNOME 1.2 and
14KDE 1 and 2. If it doesn't, the icon will appear as a toplevel window on
15user's desktop.
16
17Because not all window managers have system tray, there's no guarantee that
18wxTaskBarIcon will work correctly under X Window System and so the applications
19should use it only as an optional component of their user interface. The user
20should be required to explicitly enable the taskbar icon on Unix, it shouldn't
21be on by default.

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

62
63\func{}{wxTaskBarIcon}{\void}
64
65Default constructor.
66
67\membersection{wxTaskBarIcon::\destruct{wxTaskBarIcon}}\label{wxtaskbaricondtor}
68
69\func{}{\destruct{wxTaskBarIcon}}{\void}
70
71Destroys the wxTaskBarIcon object, removing the icon if not already removed.
72
73\membersection{wxTaskBarIcon::CreatePopupMenu}\label{wxtaskbariconcreatepopupmenu}
74
75\func{virtual wxMenu*}{CreatePopupMenu}{\void}
76
77This method is called by the library when the user requests popup menu
78(on Windows and Unix platforms, this is when the user right-clicks the icon).
79Override this function in order to provide popup menu associated with the icon.
80
81If CreatePopupIcon returns NULL (this happens by default),
82no menu is shown, otherwise the menu is
83displayed and then deleted by the library as soon as the user dismisses it.
84The events can be handled by a class derived from wxTaskBarIcon.
85
86\membersection{wxTaskBarIcon::IsIconInstalled}\label{wxtaskbariconisiconinstalled}
87
88\func{bool}{IsIconInstalled}{\void}
89
90Returns true if \helpref{SetIcon}{wxtaskbariconseticon} was called with no subsequent \helpref{RemoveIcon}{wxtaskbariconremoveicon}.
91
92\membersection{wxTaskBarIcon::IsOk}\label{wxtaskbariconisok}
93
94\func{bool}{IsOk}{\void}
95
96Returns true if the object initialized successfully.
97
98\membersection{wxTaskBarIcon::PopupMenu}\label{wxtaskbariconpopupmenu}
99
100\func{bool}{PopupMenu}{\param{wxMenu*}{ menu}}
101
102Pops up a menu at the current mouse position. The events can be handled by
103a class derived from wxTaskBarIcon.
104
105\wxheading{Note}
106
107It is recommended to override
108\helpref{CreatePopupIcon}{wxtaskbariconcreatepopupmenu}
109callback instead of calling this method from event handler, because some
110ports (e.g. wxCocoa) may not implement PopupMenu and mouse click events at all.
111
112\membersection{wxTaskBarIcon::RemoveIcon}\label{wxtaskbariconremoveicon}
113
114\func{bool}{RemoveIcon}{\void}
115
116Removes the icon previously set with \helpref{SetIcon}{wxtaskbariconseticon}.
117
118\membersection{wxTaskBarIcon::SetIcon}\label{wxtaskbariconseticon}
119
120\func{bool}{SetIcon}{\param{const wxIcon\&}{ icon}, \param{const wxString\& }{tooltip}}
121
122Sets the icon, and optional tooltip text.
