TV_DISPINFO
The TV_DISPINFO structure retrieves and sets information about a tree-view item.
typedef struct _TV_DISPINFO { tvdi
NMHDR hdr;
TV_ITEM item;
} TV_DISPINFO;
Members
hdr
Specifies a NMHDR structure, which enables a tree-view control to pass a pointer to a TV_DISPINFO structure as the lParam parameter of a WM_NOTIFY message.
item
Specifies a TV_ITEM structure that identifies and contains information about the tree-view item.
The mask member of the TV_ITEM structure specifies which information is being set or retrieved; it can be
one or more of the following values:
Value
| Meaning
| TVIF_CHILDREN
| The cChildren member specifies, or is to receive, a value that indicates whether the item
has child items.
| TVIF_IMAGE
| The iImage member specifies, or is to receive, the index of the item's non-selected icon
in the image list.
| TVIF_SELECTEDIMAGE
| The iSelectedImage member specifies, or is to receive, the index of the item's selected icon in
the image list.
| TVIF_TEXT
| The pszText member specifies the new item text or the pointer to 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 TV_ITEM 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 messages have been sent.
Remarks
A pointer to a TV_DISPINFO structure is passed as the lParam parameter when a tree-view control sends a WM_NOTIFY message with the TVN_GETDISPINFO and TVN_SETDISPINFO notification codes. A tree-view control sends these notifications in the
following situations in which the parent window of the control stores information
about a tree-view item:
- If the pszText member of the item's TV_ITEM structure is the LPSTR_TEXTCALLBACK value, the control sends these
notifications to retrieve or set the item's text.
- If the iImage or iSelectedImage member of the item's TV_ITEM structure is the I_IMAGECALLBACK value, the control sends these notifications
to retrieve or set the index of an item's icons in the control's image list.
- If the cChildren member of the item's TV_ITEM structure is the I_CHILDRENCALLBACK value, the control sends these
notifications to retrieve or set a value that indicates whether the item has child items.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
