  \class HbLongPressVisualizer

  \brief Displays the long press animation, that is, the small animated icon

  indicating that the tap being held may potentially become a long press.

  Widgets or applications should use the functions of this class to show and

  hide the standard, themed long press animation.

Q_GLOBAL_STATIC(HbLongPressVisualizerPrivate, visualizer)

/*!

  Shows the animated icon at (or near) position \a pos. If \a delayMs is non-zero then

  the animation is only shown after the specified number of milliseconds.

  \a pos is treated to be a scene position. In typical usage scenarios the scene

  position will be retrieved from a gesture event and passed as it is in \a

  pos. Do not make any assumptions about the exact position of the icon, the

  visualizer may decide to position it a bit differently in order to make it

  more visible to the user (e.g. to prevent being obscured by the user's

  finger).

  If \a widget is not 0 then the icon is added to the scene of the widget's

  mainwindow.  Otherwise the first main window is used. If no main windows were

  instantiated before calling start() then it will return immediately.

  The widget is also used for tactile feedback, if it is 0 then no feedback

  effect will be started. If the widget is given then the instant LongPressed

  feedback effect will be started automatically.

  not currently visible.
