    Detailed Description

    This element is part of the QtMobility.feedback 1.1 module.

    You can't create one of these elements directly, but several other elements inherit the methods and properties of these elements.

    There are several predefined enumerations and constants provided in this class:

    1. Duration This enum describes the possible predefined duration types. Generally a specific value in milliseconds can be supplied instead of one of these values.

    2. State This enum describes the state of the effect. An effect will be in one of these states.

    3. ErrorType This enum describes the possible errors happening on the effect.

    See also FileEffect, ThemeEffect, HapticsEffect, and QFeedbackEffect.
