The CSearchListContainer illustrates how to use CAknSearchField with list boxes to allow users to search the list items. To use this example modify the GetArrayL() method and add code to populate the text item array for the list box as well as add icons to the list box icon array. The text string format for the CAknSingleGraphicStyleListBox is “1\tText “, where 1 is a zero based index for the icon array.

If you want to use a list box without the search box option you can use the List box example instead.
