    \class HbZoomSliderPopup

    \brief HbZoomSliderPopup widget provides a vertical zoom slider embedded in a popup.

    HbZoomSliderPopup is provided for convenience. HbZoomSliderPopup sets appropriate

    icons, properties and provides zoom slider specific functionality like a

    zoom level indicator label and appropriate elements out of the box.

    HbZoomSlider sets HbSlider::text  and consists of following

    slider elements by default:

    \li HbSlider::IncreaseElement

    \li HbSlider::TrackElement

    \li HbSlider::DecreaseElement

    \li HbSlider::TextElement

    \image html hbzoomslider.png A vertical zoom slider.

    The elements can be changed by calling HbSlider::setElements() later at any time.

    then first create HbSlider and set needed elements.

    Example usage:

    \code

    HbZoomSliderPopup *slider = new HbZoomSliderPopup();

    connect(slider, SIGNAL(valueChanged(int)), receiver, SLOT(zoomSliderChanged(int)));

    \endcode

    Note:: position and size of these elements cant be change.

    Note:: if setElement is called on this slider ,  application is reponsible for

    inconsitent UI.
