Following code illustrates how to use Popup lists for displaying data along with the Icon

With this example the Popup list is constructed as CAknSinglePopupMenuStyleListBox, but you could also use Other types of Popuplists. CAknPopupList Takes an existing listbox control and puts it into a popup frame together with an optional title.

Note: The format for the item text string depends on the Popup list type. If you change the Popup list type you also need to modify the item text string format accordingly.

#include <aknlists.h> 
#include <eikimage.h>

void CBrandingPopup::ShowPopupListL()
    {
    // Create CEikTextListBox instance, list
    CEikTextListBox* list = new( ELeave ) CAknSinglePopupMenuStyleListBox;
    // Push list pointer to CleanupStack.
    CleanupStack::PushL( list );
    // Create CAknPopupList instance, popupList
    CAknPopupList* popupList = CAknPopupList::NewL( list,
                                                    R_AVKON_SOFTKEYS_SELECT_CANCEL,

    CleanupStack::PushL(popupList);
    // Initialize listbox.
