Because list boxes need to transfer several pieces of information (strings, item data, and selection indexes), the transfer buffer uses a class called TListBoxData.

TListBoxData has several data members to hold the list box information:

TListBoxData data members

Data member	Type	Description
TListBoxData::ItemDatas	TUint32Array*	Contains the item data uint32 for each item in the list box.
TListBoxData::SelIndices	TIntArray*	Contains the indexes of each selected string (in a multiple-selection list box).
TListBoxData::Strings	TStringArray*	Contains all the strings in the list box.

TListBoxData also has the following member functions to manipulate the list box data:

Member function	Description
TListBoxData::AddItemData	Adds item data to the ItemDatas array.
TListBoxData::AddString	Adds a string to the Strings array, and optionally selects it.
