1\section{\class{wxTaskBarIcon}}\label{wxtaskbaricon}
2
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.

68
69\func{}{wxTaskBarIcon}{\void}
70
71Default constructor.
72
73
74\membersection{wxTaskBarIcon::\destruct{wxTaskBarIcon}}\label{wxtaskbaricondtor}
75
76\func{}{\destruct{wxTaskBarIcon}}{\void}
77
78Destroys the wxTaskBarIcon object, removing the icon if not already removed.
79
80
81\membersection{wxTaskBarIcon::CreatePopupMenu}\label{wxtaskbariconcreatepopupmenu}
82
83\func{virtual wxMenu*}{CreatePopupMenu}{\void}
84
85This method is called by the library when the user requests popup menu
86(on Windows and Unix platforms, this is when the user right-clicks the icon).
87Override this function in order to provide popup menu associated with the icon.
88
89If CreatePopupMenu returns NULL (this happens by default),
90no menu is shown, otherwise the menu is
91displayed and then deleted by the library as soon as the user dismisses it.
92The events can be handled by a class derived from wxTaskBarIcon.
93
94
95\membersection{wxTaskBarIcon::Destroy}\label{wxtaskbaricondestroy}
96
97\func{void}{Destroy}{\void}
98
99This method is similar to \helpref{wxWindow::Destroy}{wxwindowdestroy} and can
100be used to schedule the task bar icon object for the delayed destruction: it
101will be deleted during the next event loop iteration, which allows the task bar
102icon to process any pending events for it before being destroyed.
103
104
105\membersection{wxTaskBarIcon::IsIconInstalled}\label{wxtaskbariconisiconinstalled}
106
107\func{bool}{IsIconInstalled}{\void}
108
109Returns true if \helpref{SetIcon}{wxtaskbariconseticon} was called with no subsequent \helpref{RemoveIcon}{wxtaskbariconremoveicon}.
110
111
112\membersection{wxTaskBarIcon::IsOk}\label{wxtaskbariconisok}
113
114\func{bool}{IsOk}{\void}
115
116Returns true if the object initialized successfully.
117
118
119\membersection{wxTaskBarIcon::PopupMenu}\label{wxtaskbariconpopupmenu}
120
121\func{bool}{PopupMenu}{\param{wxMenu*}{ menu}}
122
123Pops up a menu at the current mouse position. The events can be handled by
124a class derived from wxTaskBarIcon.
125
126\wxheading{Note}
127
128It is recommended to override
129\helpref{CreatePopupMenu}{wxtaskbariconcreatepopupmenu}
130callback instead of calling this method from event handler, because some
131ports (e.g. wxCocoa) may not implement PopupMenu and mouse click events at all.
132
133
134\membersection{wxTaskBarIcon::RemoveIcon}\label{wxtaskbariconremoveicon}
135
136\func{bool}{RemoveIcon}{\void}
137
138Removes the icon previously set with \helpref{SetIcon}{wxtaskbariconseticon}.
139
140
141\membersection{wxTaskBarIcon::SetIcon}\label{wxtaskbariconseticon}
142
143\func{bool}{SetIcon}{\param{const wxIcon\&}{ icon}, \param{const wxString\& }{tooltip}}
144
145Sets the icon, and optional tooltip text.
