FarListItemData

The FarListItemData structure describes the data that will be associated with an item in a DI_LISTBOX or DI_COMBOBOX list.

struct FarListItemData
{
  int   Index;
  int   DataSize;
  void *Data;
  DWORD Reserved;
};

Index

Index of the list item to which the data is associated.

DataSize

Size of Data or 0 if a null-terminated string is being associated with the item.

Data

Pointer to the data.

Reserved

Reserved.

Dialog manager allocates memory for the data associated with the list item using the following rules:

DataSize	Data
`0`	Pointer to a null-terminated string. Memory area of `strlen(Data)+1` bytes is alocated. The data is then copied to the allocated space.
`<= sizeof(DWORD)`	Character array of 4 or less elements or any pointer (`HWND` window handle, for example). No memory is allocated. Data is placed in the local area of the list item.
`> sizeof(DWORD)`	Arbitrary data. Memory area of `DataSize` bytes is allocated. The data is then copied to the allocated space.
