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.

31
32To process input from a taskbar icon, use the following event handler macros to direct input to member
33functions that take a wxTaskBarIconEvent argument. Note that not all ports are
34required to send these events and so it's better to override
35\helpref{CreatePopupMenu}{wxtaskbariconcreatepopupmenu} if all that
36the application does is that it shows a popup menu in reaction to mouse click.

59
60\func{}{wxTaskBarIcon}{\void}
61
62Default constructor.
63
64\membersection{wxTaskBarIcon::\destruct{wxTaskBarIcon}}\label{wxtaskbaricondtor}
65
66\func{}{\destruct{wxTaskBarIcon}}{\void}
67
68Destroys the wxTaskBarIcon object, removing the icon if not already removed.
69
70\membersection{wxTaskBarIcon::CreatePopupMenu}\label{wxtaskbariconcreatepopupmenu}
71
72\func{virtual wxMenu*}{CreatePopupMenu}{\void}
73
74This method is called by the library when the user requests popup menu
75(on Windows and Unix platforms, this is when the user right-clicks the icon).
76Override this function in order to provide popup menu associated with the icon.
77
78If CreatePopupIcon returns NULL (this happens by default),
79no menu is shown, otherwise the menu is
80displayed and then deleted by the library as soon as the user dismisses it.
81The events can be handled by a class derived from wxTaskBarIcon.
82
83\membersection{wxTaskBarIcon::IsIconInstalled}\label{wxtaskbariconisiconinstalled}
84
85\func{bool}{IsIconInstalled}{\void}
86
87Returns true if \helpref{SetIcon}{wxtaskbariconseticon} was called with no subsequent \helpref{RemoveIcon}{wxtaskbariconremoveicon}.
88
89\membersection{wxTaskBarIcon::IsOk}\label{wxtaskbariconisok}
90
91\func{bool}{IsOk}{\void}
92
93Returns true if the object initialized successfully.
94
95\membersection{wxTaskBarIcon::PopupMenu}\label{wxtaskbariconpopupmenu}
96
97\func{bool}{PopupMenu}{\param{wxMenu*}{ menu}}
98
99Pops up a menu at the current mouse position. The events can be handled by
100a class derived from wxTaskBarIcon.
101
102\wxheading{Note}
103
104It is recommended to override
105\helpref{CreatePopupIcon}{wxtaskbariconcreatepopupmenu}
106callback instead of calling this method from event handler, because some
107ports (e.g. wxCocoa) may not implement PopupMenu and mouse click events at all.
108
109\membersection{wxTaskBarIcon::RemoveIcon}\label{wxtaskbariconremoveicon}
110
111\func{bool}{RemoveIcon}{\void}
112
113Removes the icon previously set with \helpref{SetIcon}{wxtaskbariconseticon}.
114
115\membersection{wxTaskBarIcon::SetIcon}\label{wxtaskbariconseticon}
116
117\func{bool}{SetIcon}{\param{const wxIcon\&}{ icon}, \param{const wxString\& }{tooltip}}
118
119Sets the icon, and optional tooltip text.
