    \class HbFeedbackSettings

    \brief %Feedback Settings API for Qt application development.

    Application can choose to disable feedback effects for the application, for example

    phone application may want to disable vibration and sound feedback effects during a phone call.

    Feedback effects can also be disabled based on the type of feedback. There are currently four

    supported types of feedback: instant fire&forget feedback, continuous feedback that needs to

    be started and ended separately, hit area feedback that uses pre-registered feedback areas and

    finally tacticon feedback.
