CTreeCtrl::CreateDragImage
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.
CImageList* CreateDragImage(
HTREEITEM hItem
);
Parameters
- hItem
Handle of the tree item to be dragged.
Return Value
Pointer to the image list to which the dragging bitmap was added, if successful; otherwise NULL.
Remarks
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:
HTREEITEM hItem =m_TreeCtrl.GetSelectedItem();
CImageList* pImageList = m_TreeCtrl.CreateDragImage(hItem);
// Do something with the image list.
delete pImageList;
