NMTVDISPINFOA structure (commctrl.h)
Contains and receives display information for a tree-view item. This structure is identical to the TV_DISPINFO structure, but it has been renamed to follow current naming conventions.
Syntax
typedef struct tagTVDISPINFOA {
NMHDR hdr;
TVITEMA item;
} NMTVDISPINFOA, *LPNMTVDISPINFOA;
Members
hdr
Type: NMHDR
NMHDR structure that contains information about this notification.
item
Type: TVITEM
TVITEM structure that identifies and contains information about the tree-view item. The mask member of the TVITEM structure specifies which information is being set or retrieved. It can be one or more of the following values:
| Value | Meaning |
|---|---|
|
The cChildren member specifies, or is to receive, a value that indicates whether the item has child items. |
|
The iImage member specifies, or is to receive, the index of the item's nonselected icon in the image list. |
|
The iSelectedImage member specifies, or is to receive, the index of the item's selected icon in the image list. |
|
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, you typically copy the text to the buffer pointed to by the pszText member of the TVITEM structure. However, you can return a string in the pszText member instead. If you do so, you cannot change or delete the string until the corresponding item text is deleted or until two additional TVN_GETDISPINFO notification codes have been sent. |
Remarks
Note
The commctrl.h header defines NMTVDISPINFO as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
