LV_DISPINFO
The LV_DISPINFO structure contains information needed to display an owner-drawn item in a
list view control.
typedef struct tagLV_DISPINFO {
NMHDR hdr;
LV_ITEM item;
} LV_DISPINFO;
Members
hdr
Specifies a NMHDR structure. The code member of this structure identifies the notification message being sent. It
can be one of the following notification codes: LVN_GETDISPINFO or LVN_SETDISPINFO.
item
Specifies an LV_ITEM structure that identifies the item or subitem. The structure either contains
or receives information about the item. The mask member contains a set of bit flags that specify which item attributes are
relevant. You can set one or more of the following bit flags:
Value
| Meaning
| LVIF_IMAGE
| The iImage member specifies, or is to receive, the index of the item's icon in the image
list.
| LVIF_STATE
| The state member specifies, or is to receive, the state of the item.
| LVIF_TEXT
| The pszText member specifies the new item text or the address of a buffer that is to
receive the item text.
|
If the structure is receiving item text, the pszText and cchTextMax members specify the address and size of a buffer. You can either copy text to
the buffer or assign the address of a string to the pszText member. In the latter case, you must not change or delete the string until
the corresponding item text is deleted or two additional LVN_GETDISPINFO messages
have been sent.
If you are handling the LVN_GETDISPINFO message, you can set the
LVIF_DI_SETITEM flag in the mask member. This tells the operating system to store the requested list item
information, and not ask for it again.
Remarks
When a list view control sends the LVN_GETDISPINFO or LVN_SETDISPINFO
notification codes, it passes a pointer to an LV_DISPINFO structure as the lParam parameter of a WM_NOTIFY message.
