    @class wxToolTip

    This class holds information about a tooltip associated with a window (see
    wxWindow::SetToolTip()).

    The four static methods, wxToolTip::Enable(), wxToolTip::SetDelay()
    wxToolTip::SetAutoPop() and wxToolTip::SetReshow() can be used to globally
    alter tooltips behaviour.
