  @endverbatim

 * The type field while defining find can be one of the following:

 @verbatim

 EAknCtSelectionListFixedFind

 EAknCtSelectionListPopupFind

 EAknCtSelectionListAdaptiveFind

 @endverbatim

 *

 * The menubar you give for selection list dialog should have

 * one of the following as one of its menu panes (defined in avkon.hrh):

 @verbatim

 R_AVKON_MENUPANE_SELECTION_LIST

 R_AVKON_MENUPANE_SELECTION_LIST_WITH_FIND_POPUP

 @endverbatim

 * @code

 * RESOURCE MENU_BAR r_res_id_for_a_menubar

 * {

 * titles =

 *     {

 *     MENU_TITLE { menu_pane = R_AVKON_MENUPANE_SELECTION_LIST; } 

 *     };

 * };

 * @endcode

 * C++ Usage:

 * @code

 *    TInt openedItem = 0;

 *    MDesCArray *array = ...;

 *    CAknSelectionListDialog *dialog = CAknSelectionListDialog::NewL(openedItem, array, R_RES_ID_FOR_A_MENUBAR);

 *    TInt result = dialog->ExecuteLD(R_RES_ID_FOR_A_DIALOG);

 *    if (result)

 *        {

 *        ...use openeditem here...

 *        }

 *    else

 *        {

 *        ...canceled...

 *        }

 *

 * @endcode

 * Alternatively, you can use:

 * @code

 *    TInt openedItem = 0;

 *    MDesCArray *array = ...;

 *    CAknSelectionListDialog *dialog = CAknSelectionListDialog::NewL(openedItem, array, R_RES_ID_FOR_A_MENUBAR);

 *    dialog->PrepareLC(R_RES_ID_FOR_A_DIALOG);

 *    // do some operations here, for example fill icon array 

 *    TInt result = dialog->RunLD();

 *    if (result)

 *        {

 *        ...

 *        }

 *    else

 *        {

 *        ...

 *        }

 * @endcode

 *

 * Often it is also useful to derive from CAknSelectionListDialog and implement OkToExitL(), constructors and the NewL() methods.

 * OkToExitL() implementation helps with providing navigation with other dialogs; OkToExitL() is ideal place to launch

 * new dialogs when a list item is selected. This way when backstepping, the state of the first dialog is preserved...
