    \class CpDataFormButtonEntryViewItem
    \brief The CpDataFormButtonEntryViewItem is a item proto type of HbDataForm which is supplied by control panel.
	When you want use setting items which are come from control panel, you should append this class to the proto type list of your data form's instance.
	Code example:
	\code
	HbDataForm *form = new HbDataForm();
	QList<HbAbstractViewItem *> protoType = form->itemProtoTypetypes();
	protoType.append(CpDataFormButtonEntryViewItem::createCpItemProtoType());
	form->setItemPrototypes();
	\endcode
