    22     \class CxuiZoomSlider

    23     \brief CxuiZoomSlider is a camera specific slider that is derived from HbSlider

    24 

    25     CxuiZoomslider has been created so that we are able to control and filter user

    26     mouse press events. All mouse press events that happen in slider rect are

    27     accepted in this class so that they won't be given any other components.

    28     This has to be done to prevent the slider to dismiss when accidentally 

    29     missing e.g.slider thumb touch area (camera view underneath will get the 

    30     event and hide the slider).
