\section{\class{wxTaskBarIcon}}\label{wxtaskbaricon}
|
|
|
|
This class represents a taskbar icon, appearing in the `system tray' and
|
|
responding to mouse clicks. An icon has an optional tooltip. This class is only
|
|
supported under Windows 95/NT and in X Window System ports (wxGTK, wxMotif,
|
|
wxX11).
|
|
|
|
\wxheading{X Window System Note}
|
|
|
|
Under X Window System, the window manager must support either
|
|
the \urlref{System Tray Protocol by freedesktop.org}{http://freedesktop.org/Standards/systemtray-spec}
|
|
(WMs used by modern desktop environments such as GNOME >= 2, KDE
|
|
>= 3 and XFCE >= 4 all do) or the older methods used in GNOME 1.2 and
|
|
KDE 1 and 2. If it doesn't, the icon will appear as a toplevel window on
|
|
user's desktop.
|
|
|
|
Because not all window managers have system tray, there's no guarantee that
|
|
wxTaskBarIcon will work correctly under X Window System and so the applications
|
|
should use it only as an optional component of their user interface. The user
|
|
should be required to explicitly enable the taskbar icon on Unix, it shouldn't
|
|
be on by default.

To process input from a taskbar icon, use the following event handler macros to direct input to member
|
|
functions that take a wxTaskBarIconEvent argument.

|
\func{}{wxTaskBarIcon}{\void}
|
|
|
|
Default constructor.
