46     \brief HbListWidget represents a list

    46     \brief The HbListWidget class is for simple lists consisting of single row items of an icon and some text, and together with HbListWidgetItem consisting of icon and at most two-row text items.

    47 

    47 

    48     This class has been provided with the class HbListWidgetItem as a convenience

    48     

    49     API. It provides an item-based interface for adding and removing items. 

    49     HbListWidget provides a convenience API for adding, modifying, and removing single row items in simple lists. Single row items consist of some text and an icon in one line. If you want list items with two texts or two icons, that is, with multirow items, then you can create HbListWidgetItem objects and add them to an HbListWidget. See HbListWidgetItem for the detailed description of the multirow item.

    51     SetModel() function of the base class HbListView cannot be used. If the user wants to start 

    51      HbListWidget model supports arranging items with drag and drop.

    52     using a list view with e.g. a directory model (QDirModel) this convenience API cannot be used.

    53     

    53      \link HbAbstractItemView::setModel(QAbstractItemModel *model, HbAbstractViewItem *prototype=0) SetModel()\endlink method of the base class HbAbstractItemView cannot be used. HbListWidget cannot be used for list views with a directory model (QDirModel), for example.

    54     HbListWidget can be used without HbListWidgetItem to populate 

    54     

    55     simple list with single row items consisting of a text and an icon.

    86     This signal is emitted when the user activates an item in the list. \a item indicates the activated item. The activation of the item depends on the input method. An item can be activated in the following ways:

    88     How to activate items depends on the input method; e.g., with mouse by clicking the item,

    87     - by clicking the item with a mouse

    89     or with touch input by tapping the item, or with hardware keys by pressing the Return

    88     - by tapping the item on a touch screen

    90     or Enter key when the item is current, or with soft keys by pressing choosing "Select"

    89     - by pressing Return or Enter hardware keys when the item has focus

    91     when the item is current.
