TVM_CREATEDRAGIMAGE
The TVM_CREATEDRAGIMAGE message creates a dragging bitmap for the specified
item in a tree-view control, creates an image list for the bitmap, and adds the
bitmap to the image list. An application can display the image when dragging the
item by using the image-list functions. You can send this message explicitly
or by using the TreeView_CreateDragImage macro.
TVM_CREATEDRAGIMAGE
wParam = 0;
lParam = (LPARAM) (HTREEITEM) hitem;
Parameters
hitem
Handle to the item that receives the new dragging bitmap.
Return Values
Returns the handle of the image list to which the dragging bitmap was added if
successful or NULL otherwise.
Remarks
If you create a tree-view control without an associated image list, you cannot
use the TVM_CREATEDRAGIMAGE message to create the image to display during a
drag operation. You must implement your own way to support drag and drop cursor.
