    \class HbListWidgetItem

    \brief HbListWidgetItem represents a list item. It is part of convenience list API together with HbListWidget. 

    As this is a convenience API it is supposed to be easy to use. For that reason complicated list items are not possible

    The following code snippet presents how to create an list item with icons in the left 

    and right columns and two rows of text in the middle column.
