CTreeCtrl::CreateDragImage

CImageList* CreateDragImage( HTREEITEM hItem );

Return Value

Pointer to the image list to which the dragging bitmap was added, if successful; otherwise NULL.

Parameters

hItem

Handle of the tree item to be dragged.

Remarks

Call this function to create a dragging bitmap for the given item in a tree view control, create an image list for the bitmap, and add the bitmap to the image list. An application uses the image-list functions to display the image when the item is being dragged.

The CImageList object is permanent, and you must delete it when finished. For example:

CImageList* pImageList = MyTreeCtrl.CreateDragImage(nItem, &point);
   ...
   ...
   delete pImageList;
