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.

30\wxheading{Event handling}
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.

62\membersection{wxTaskBarIcon::wxTaskBarIcon}\label{wxtaskbariconctor}
63
64\func{}{wxTaskBarIcon}{\void}
65
66Default constructor.
67
68\membersection{wxTaskBarIcon::\destruct{wxTaskBarIcon}}\label{wxtaskbaricondtor}
69
70\func{}{\destruct{wxTaskBarIcon}}{\void}
71
72Destroys the wxTaskBarIcon object, removing the icon if not already removed.
73
74\membersection{wxTaskBarIcon::CreatePopupMenu}\label{wxtaskbariconcreatepopupmenu}
75
76\func{virtual wxMenu*}{CreatePopupMenu}{\void}
77
78This method is called by the library when the user requests popup menu
79(on Windows and Unix platforms, this is when the user right-clicks the icon).
80Override this function in order to provide popup menu associated with the icon.
81
82If CreatePopupMenu returns NULL (this happens by default),
83no menu is shown, otherwise the menu is
84displayed and then deleted by the library as soon as the user dismisses it.
85The events can be handled by a class derived from wxTaskBarIcon.
86
87\membersection{wxTaskBarIcon::IsIconInstalled}\label{wxtaskbariconisiconinstalled}
88
89\func{bool}{IsIconInstalled}{\void}
90
91Returns true if \helpref{SetIcon}{wxtaskbariconseticon} was called with no subsequent \helpref{RemoveIcon}{wxtaskbariconremoveicon}.
92
93\membersection{wxTaskBarIcon::IsOk}\label{wxtaskbariconisok}
94
95\func{bool}{IsOk}{\void}
96
97Returns true if the object initialized successfully.
98
99\membersection{wxTaskBarIcon::PopupMenu}\label{wxtaskbariconpopupmenu}
100
101\func{bool}{PopupMenu}{\param{wxMenu*}{ menu}}
102
103Pops up a menu at the current mouse position. The events can be handled by
104a class derived from wxTaskBarIcon.
105
106\wxheading{Note}
107
108It is recommended to override
109\helpref{CreatePopupMenu}{wxtaskbariconcreatepopupmenu}
110callback instead of calling this method from event handler, because some
111ports (e.g. wxCocoa) may not implement PopupMenu and mouse click events at all.
112
113\membersection{wxTaskBarIcon::RemoveIcon}\label{wxtaskbariconremoveicon}
114
115\func{bool}{RemoveIcon}{\void}
116
117Removes the icon previously set with \helpref{SetIcon}{wxtaskbariconseticon}.
118
119\membersection{wxTaskBarIcon::SetIcon}\label{wxtaskbariconseticon}
120
121\func{bool}{SetIcon}{\param{const wxIcon\&}{ icon}, \param{const wxString\& }{tooltip}}
122
123Sets the icon, and optional tooltip text.
