\brief The HbFeedback namespace defines the feedback effects supported

    by the current feedback framework.

    As a widget developer, you may want to give feedback to the user

    corresponding to how the user interacts with the device. Feedback can

    be given using different modalities supported on the device, such as

    tactile, audio, or visual. Tactile feedback is feedback that is 'felt'

    by the user, for example vibration of the device. Extra visual feedback,

    in addition to the user interface changes on the screen, can be flashing

    the screen or switching extra lights on the device on or off. The feedback

    mechanism of the device can be further extended by implementing other

    modality plug-ins (see HbFeedbackEffectPlugin).

    Instant feedback is a fire-and-forget type of feedback which initiates a short

    tactile and/or sound feedback effect. Each enumeration value corresponds

    to a certain instant feedback effect.

    For many standard instant effects, there is both a 'basic' and 'sensitive'

    version. The sensitive feedback effect is for situations where the triggering

    action is not important, or where there can be a large number of feedback

    instances within a short time. An example of a less important touch event is

    when the focus is changed in a list, while an example of a situation where

    lots of events could be triggered is when the device user selects text and

    feedback is given for every character selected.

    Continuous feedback is a feedback type that you can use to provide

    ongoing feedback in situations where the user is performing some

    longer duration touch interaction, such as dragging a slider handle

    to change the slider value. You need to explicitly start and stop

    a continuous feedback effect. You can update continuous feedback intensity

    during the playback between values 0 and 100 with HbContinuousFeedback::setIntensity().

    The feedback framework uses HbFeedback::ContinuousEffect for its

    internal purposes as well, and it will also stop any continuous feedback

    playback when a timeout occurs.

    The available modalities for feedback effects. The currently supported

    modalities are audio and tactile. Effects can be played using both

    modalities or only one of them.

*/

/*! 

    \var HbFeedback::Modality HbFeedback::All

    All available modalities.

/*! 

    \var HbFeedback::Modality HbFeedback::Audio

    Audio modality.

*/

/*! 

    \var HbFeedback::Modality HbFeedback::Tactile

    Tactile modality.

    A timeout value has to be defined for each continuous feedback to avoid

    situations where the continuous feedback is never stopped and unintentionally

    continues to play indefinitely.
