@class wxTaskBarIcon
|
|
|
|
This 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.
|
|
|
|
|
|
@section taskbaricon_xnote X Window System Note
|
|
|
|
Under X Window System, the window manager must support either the
|
|
"System Tray Protocol" (see http://freedesktop.org/wiki/Specifications/systemtray-spec)
|
|
by freedesktop.org (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.
|
|
|
|
@beginEventEmissionTable{wxTaskBarIconEvent}
|
|
Note that not all ports are required to send these events and so it's better
|
|
to override wxTaskBarIcon::CreatePopupMenu() if all that the application does
|
|
is that it shows a popup menu in reaction to mouse click.
|
|
@event{EVT_TASKBAR_MOVE(func)}
|
|
Process a @c wxEVT_TASKBAR_MOVE event.
|
|
@event{EVT_TASKBAR_LEFT_DOWN(func)}
|
|
Process a @c wxEVT_TASKBAR_LEFT_DOWN event.
|
|
@event{EVT_TASKBAR_LEFT_UP(func)}
|
|
Process a @c wxEVT_TASKBAR_LEFT_UP event.
|
|
@event{EVT_TASKBAR_RIGHT_DOWN(func)}
|
|
Process a @c wxEVT_TASKBAR_RIGHT_DOWN event.
|
|
@event{EVT_TASKBAR_RIGHT_UP(func)}
|
|
Process a @c wxEVT_TASKBAR_RIGHT_UP event.
|
|
@event{EVT_TASKBAR_LEFT_DCLICK(func)}
|
|
Process a @c wxEVT_TASKBAR_LEFT_DCLICK event.
|
|
@event{EVT_TASKBAR_RIGHT_DCLICK(func)}
|
|
Process a @c wxEVT_TASKBAR_RIGHT_DCLICK event.
|
|
@event{EVT_TASKBAR_CLICK(func)}
|
|
This is a synonym for either EVT_TASKBAR_RIGHT_DOWN or UP depending on
|
|
the platform, use this event macro to catch the event which should result
|
|
in the menu being displayed on the current platform.
